실버세대의 중요성은 인구 증가뿐만 아니라 구매력의 향상 및 의사 표현의 강도가 증가하면서 더욱 커지고 있다. 이에 따라 과거 실버세대 전체를 대상으로 접근하던 마케팅 전략은 실버세대의 특성에 따라 적절히 분류하여 접근하는 방식으로 수정되는 것이 적절하다. 또한 세분군 분류 결과에 따라 고객 접근 전략이 결정되므로, 세분군이 얼마나 동일한 특성을 보유하고 있는 지는 마케팅 계획 수립에 매우 중요한 요소가 된다. 따라서 이론적으로 동일 세분군에 속해 있는 고객의 니즈는 대체로 일치해야 한다. 본 연구에서는 실버세대의 생활 행태와 생애 단계를 감안하여, 실버 세대 대상의 마케팅을 위한 세분군 (細分群) 분류를 수행하였으며, 분류된 세분군의 니즈가 얼마나 일치하고 있는지를 측정하기 위하여 동질도 (DoH: Degrees of Homogeneity)를 측정하였다. 동질도는 각 세분군을 대상으로 수행된 설문조사의 객관식 문항 별로 최다 응답자가 선택한 보기 문항이 다른 문항에 비하여 유의미하게 많다고 판단되는 문항의 수를 전체 문항의 수로 나눈 것으로 정의하였다. 본 연구는 동질도를 활용한 세분군 분류 결과의 적절성 평가 방법을 제시하였다는데 의의가 있으며, 다양한 분야에서 응용될 수 있을 것으로 판단된다. 또한 본 연구에서 제시한 실버세대 세분군 분류 결과는 점차 증가하고 있는 실버세대를 위한 마케팅 방안 수립의 기본 자료로 활용될 수 있을 것으로 판단된다.

The main purpose of this study was to test the effect of the structured information on the sleep amount of the patients undergoing open heart surgery. This study has specifically addressed to the Following two basic research questions: (1) Would the structed in formation influence in the reduction of sleep disturbance related to anxiety and Physical stress before and after the operation? and (2) that would be the effects of the structured information on the level of preoperative state anxiety, the hormonal change, and the degree of behavioral change in the patients undergoing an open heart surgery? A Quasi-experimental research was designed to answer these questions with one experimental group and one control group. Subjects in both groups were matched as closely as possible to avoid the effect of the differences inherent to the group characteristics, Baseline data were also. collected on both groups for 7 days prior to the experiment and found that subjects in both groups had comparable sleep patterns, trait anxiety, hormonal levels and behavioral level. A structured information as an experimental input was given to the subjects in the experimental group only. Data were collected and compared between the experimental group and the control group on the sleep amount of the consecutive pre and post operative days, on preoperative state anxiety level, and on hormonal and behavioral changes. To test the effectiveness of the structured information, two main hypotheses and three sub-hypotheses were formulated as follows; Main hypothesis 1: Experimental group which received structured information will have more sleep amount than control group without structured information in the night before the open heart surgery. Main hypothesis 2: Experimental group with structured information will have more sleep, amount than control group without structured information during the week following the open heart surgery Sub-hypothesis 1: Experimental group with structured information will be lower in the level of State anxiety than control group without structured information in the night before the open heart surgery. Sub-hypothesis 2 : Experimental group with structured information will have lower hormonal level than control group without stuctured information on the 5th day after the open heart surgery Sub-hypothesis 3: Experimental group with structured information will be lower in the behavioral change level than control group without structured information during the week after the open heart surgery. The research was conducted in a national university hospital in Seoul, Korea. The 53 Subjects who participated in the study were systematically divided into experimental group and control group which was decided by random sampling method. Among 53 subjects, 26 were placed in the experimental group and 27 in the control group. Instruments; (1) Structed information: Structured information as an independent variable was constructed by the researcher on the basis of Roy's adaptation model consisting of physiologic needs, self-concept, role function and interdependence needs as related to the sleep and of operational procedures. (2) Sleep amount measure: Sleep amount as main dependent variable was measured by trained nurses through observation on the basis of the established criteria, such as closed or open eyes, regular or irregular respiration, body movement, posture, responses to the light and question, facial expressions and self report after sleep. (3) State anxiety measure: State Anxiety as a sub-dependent variable was measured by Spi-elberger's STAI Anxiety scale, (4) Hormornal change measure: Hormone as a sub-dependent variable was measured by the cortisol level in plasma. (5) Behavior change measure: Behavior as a sub-dependent variable was measured by the Behavior and Mood Rating Scale by Wyatt. The data were collected over a period of four months, from June to October 1981, after the pretest period of two months. For the analysis of the data and test for the hypotheses, the t-test with mean differences and analysis of covariance was used. The result of the test for instruments show as follows: (1) STAI measurement for trait and state anxiety as analyzed by Cronbachs alpha coefficient analysis for item analysis and reliability showed the reliability level at r= .90 r= .91 respectively. (2) Behavior and Mood Rating Scale measurement was analyzed by means of Principal Component Analysis technique. Seven factors retained were anger, anxiety, hyperactivity, depression, bizarre behavior, suspicious behavior and emotional withdrawal. Cumulative percentage of each factor was 71.3%. The result of the test for hypotheses show as follows; (1) Main hypothesis, was not supported. The experimental group has 282 minutes of sleep as compared to the 255 minutes of sleep by the control group. Thus the sleep amount was higher in experimental group than in control group, however, the difference was not statistically significant at .05 level. (2) Main hypothesis 2 was not supported. The mean sleep amount of the experimental group and control group were 297 minutes and 278 minutes respectively Therefore, the experimental group had more sleep amount as compared to the control group, however, the difference was not statistically significant at .05 level. Thus, the main hypothesis 2 was not supported. (3) Sub-hypothesis 1 was not supported. The mean state anxiety of the experimental group and control group were 42.3, 43.9 in scores. Thus, the experimental group had slightly lower state anxiety level than control group, howe-ver, the difference was not statistically significant at .05 level. (4) Sub-hypothesis 2 was not supported. . The mean hormonal level of the experimental group and control group were 338 ㎍ and 440 ㎍ respectively. Thus, the experimental group showed decreased hormonal level than the control group, however, the difference was not statistically significant at .05 level. (5) Sub-hypothesis 3 was supported. The mean behavioral level of the experimental group and control group were 29.60 and 32.00 respectively in score. Thus, the experimental group showed lower behavioral change level than the control group. The difference was statistically significant at .05 level. In summary, the structured information did not influence the sleep amount, state anxiety or hormonal level of the subjects undergoing an open heart surgery at a statistically significant level, however, it showed a definite trends in their relationships, not least to mention its significant effect shown on behavioral change level. It can further be speculated that a great degree of individual differences in the variables such as sleep amount, state anxiety and fluctuation in hormonal level may partly be responsible for the statistical insensitivity to the experimentation.

목적: 조기위암은 진행위암에 비해 월등히 좋은 예후를 보인다. 조기위암의 5년 생존율은 현재 $90\%$를 상회하며 치료가 가능한 암으로 알려져 있다. 특히 조기위암에서 중요한 예후인자는 림프절 전이의 존재 여부이다. 요즘 조기 위암에 대해 보존적 술식이 제안되고 있지만 각 개인에 있어서 적절한 술식을 선택하는 것은 매우 중요하다. 이후향적 연구는 점막하층암에서 적절한 치료 방법을 결정하기 위해서 임상병리학적 형태와 림프절 전이와 관련된 인자들을 명확히 하기 위해 시행되었다. 대상 및 방법: 본 연구의 대상은 전남대학교병원에서 1981년부터 1999년 사이에 수술을 받았던 점막하층암(I군) 279예의 임상병리학적 특징을 점막암(II군), 근육층암(III군)과 비교한 것이다. 각 군들 간에 나이, 성별, 종양의 위치, 간 전이 여부, 복막파종 여부 등은 통계적으로 유의한 차이는 없었다. 결과: 림프절 전이는 점막하층암 279명 중 47명($16.8\%$)에서 보였다. 점막하층암에서 림프절 전이는 점막에서 보다 유의하게 높았다($16.8\%\;vs.\;3.9\%$; P<0.01). 점막하층암(I군)에서 5년 생존율은 $88.6\%$이며 점막암(II군)과 근육층암(III군)에서는 각각 $95.2\%$와 $72.7\%$였다(I군 vs. II군, I군 vs. III군; P<0.01). 점막하층암 환자에서 림프절 전이가 있는 경우 생존율은 림프절 전이가 없는 경우에 비해 유의하게 불량하였다($82.2\%\;vs.\;93.6\%$; P<0.01). 결론: 점막하층암에서 림프절의 전이유무가 중요한 예후인자이므로 D2 림프절 곽청술을 포함한 위절제술이 점막 하층암 환자에서 적절한 수술적 방법으로 사료된다. 예후 인자라고 할 수 있다. STI-571은 재발 혹은 전이 환자에 있어 치료 효과를 나타내므로 술후 치료에 적용하는 것이 예후 향상에 기여하리라 생각된다.한 검사로 환자의 일반적인 상태를 반영하며, 특히 혈소판 증가증, 혈청 알부민 감소, 빈혈 등이 나타난 경우 병의 예후가 나쁠 것임을 예측하는데 유용한 것으로 판단된다.서는 C/C 116($40\%$), C/T 103$40\%$), T/T 68($24\%$)이었다(P=0.045). 암의 위치에 따른 MTHFR유전자형의 분포는 위 하부에서 C/C 16($28\%$), C/T & T/T 42($77\%$)이었고, 위 중부 및 상부에서 C/C 2($5\%$), C/T & T/T 36($75\%$) 이었다(P=0.006). 환자군 내에서 흡연력 유무에 따른 MTHFR유전 자형의 분포는 흡연력이 있을 때 C/C 13($23\%$), C/T & T/T 43($77\%$)이었고, 흡연력이 없을 때 C/C 5($12\%$), C/T & T/T 35 ($88\%$)였다(P=0.189). 환자군 내에서 음주력 유무에 따른 MTHFR유전자형의 분포는 음주력이 있을 때 C/C 12($26\%$), C/T & T/T 33($74\%$)이었고, 음주력이 없을 때 C/C 6($12\%$), CT & T/T 45($88\%$)였다.(P=0.063). 결론: 본 연구에서는 MTHFR C/T & T/T 유전자 다형성이 위암의 발생과 그 위치에 대해 관련이 있는 것으로 여겨지고, 흡연력, 음주력과는 관련이 없는 것으로 여겨진다.

I. Subject of the study A study on the nutritive value and utilization of powdered seaweeds. II. Purpose and Importance of the study A. In Korea the shortage of food will be inevitable by the rapidly growing population. It will be very important study to develop a new food from the seaweeds which were not used hitherto for human consumption. B. The several kinds of seaweeds have been used by man in Korea mainly as side-dishes. However, a properly powdered seaweed will enable itself to be a good supplement or mixture to certain cereal flours. C. By adding the powdered seaweed to any cereals which have long been staple foods in this country the two fold benefits; saving of cereals and change of dietary pattern, will be secured. III. Objects and scope of the study A. Objects of the study The objects will come under four items. 1. To develop a powdered seaweed as a new food from the seaweeds which have been not used for human consumption. 2. To evaluate the nutritional quality of the products the analysis for chemical composition and animal feeding experiment will be conducted. 3. Experimental cocking and accepability test will be conducted for the powdered products to evaluate the value as food stuff. 4. Sanitary test and also economical analysis will be conducted for the powdered products. B. Scope of the study 1. Production of seaweed powders Sargassum fulvellum growing in eastern coast and Sargassum patens C.A. in southern coast were used as the material for the powders. These algae, which have been not used for human consumption, were pulverized through the processes of washing, drying, pulverization, etc. 2. Nutritional experiments a. Chemical composition Proximate components (water, protein, fat, cellulose, sugar, ash, salt), minerals (calcium, phosphorus, iron, iodine), vitamins (A, $B_1,\;B_2$ niacin, C) and amino acids were analyzed for the seaweed powders. b. Animal feeding experiment Weaning 160 rats (80 male and 80 female rats) were used as experimental animals, dividing them into 16 groups, 10 rats each group. Each group was fed for 12 weeks on cereal diet (Wheat flour, rice powder, barley powder, potato powder, corn flour) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. After the feeding the growth, feed efficiency ratio, protain efficiency ratio and ,organs weights were checked and urine analysis, feces analysis and serum analysis were also conducted. 3. Experimental cooking and acceptability test a. Several basic studies were conducted to find the characteristics of the seaweed powder. b. 17 kinds of Korean dishes and 9 kinds of foreign dishes were prepared with cereal flours (wheat, rice, barley, potato, corn) with the supplementary levels of 5%, 10%, 15%, 20% and 30% of the seaweed powder. c. Acceptability test for the dishes was conducted according to plank's Form. 4. Sanitary test The heavy metals (Cd, Pb, As, Hg) in the seaweed powders were determined. 5. Economical analysis The retail price of the seaweed powder was compared with those of other cereals in the market. And also economical analysis was made from the nutritional point of view, calculating the body weight gained in grams per unit price of each feeding diet. IV. Results of the study and the suggestion for application A. Chemical composition 1. There is no any big difference in proximate components between powders of Sargassum fulvellum in eastern coast and Sargassum patens C.A. in southern coast. Seasonal difference is also not significant. Higher levels of protein, cellulose, ash and salt were found in the powders compared with common cereal foods. 2. The levels of calcium (Ca) and iron (Fe) in the powders were significantly higher than common cereal foods and also rich in iodine (I). Existence of vitamin A and vitamin C in the Powders is different point from cereal foods. Vitamin $B_1\;and\;B_2$ are also relatively rich in the powders.'Vitamin A in ·Sargassum fulvellum is high and the levels of some minerals and vitamins are seemed4 to be some influenced by seasons. 3. In the amino acid composition methionine, isoleucine, Iysine and valine are limiting amino acids. The protein qualities of Sargassum fulvellum and Sargassum patens C.A. are seemed to be .almost same and generally ·good. Seasonal difference in amino acid composition was found. B. Animal feeding experiment 1. The best growth was found at.10% supplemental level of the seaweed Powder and lower growth rate was shown at 30% level. 2. It was shown that 15% supplemental level of the Seaweed powder seems to fulfil, to some extent the mineral requirement of the animals. 3. No any changes were found in organs development except that, in kidney, there found decreasing in weight by increasing the supplemental level of the seaweed powder. 4. There is no any significant changes in nitrogen retention, serum cholesterol, serum calcium and urinary calcium in each supplemental level of the seaweed powder. 5. In animal feeding experiment it was concluded that $5%{\sim}15%$ levels supplementation of the seaweed powder are possible. C. Experimental cooking and acceptability test 1. The seaweed powder showed to be utilized more excellently in foreign cookings than in Korean cookings. Higher supplemental level of seaweed was passible in foreign cookings. 2. Hae-Jo-Kang and Jeon-Byung were more excellent than Song-Pyun, wheat cake, Soo-Je-Bee and wheat noodle. Hae-Je-Kang was excellent in its quality even as high as 5% supplemental level. 3. The higher levels of supplementation were used the more sticky cooking products were obtained. Song-Pyun and wheat cake were palatable and lustrous in 2% supplementation level. 4. In drop cookie the higher levels of supplementation, the more crisp product was obtained, compared with other cookies. 5. Corn cake, thin rice gruel, rice gruel and potato Jeon-Byung were more excellent in their quality than potato Man-Doo and potato noodle. Corn cake, thin rice gruel and rice gruel were excellent even as high as 5% supplementation level. 6. In several cooking Porducts some seaweed-oder was perceived in case of 3% or more levels of supplementation. This may be much diminished by the use of proper condiments. D. Sanitary test It seems that there is no any heavy metals (Cd, Pb, As, Hg) problem in these seaweed Powders in case these Powders are used as supplements to any cereal flours E. Economical analysis The price of the seaweed powder is lower than those of other cereals and that may be more lowered when mass production of the seaweed powder is made in future. The supplement of the seaweed powder to any cereals is also economical with the criterion of animal growth rate. F. It is recommended that these seaweed powders should be developed and used as supplement to any cereal flours or used as other food material. By doing so, both saving of cereals and improvement of individual's nutrition will greatly be achieved. It is also recommended that the feeding experiment for men would be conducted in future.

본 논문의 목적은 무형문화유산 일반전승자의 역할을 주목하면서, 소셜 네트워크 분석을 활용해 무형문화유산 전승공동체의 연결망과 전승활동에서 발생하는 지식 흐름의 구조적 특징을 분석하는 데 있다. 이러한 연구 목적을 이루기 위해 본 논문에서는 연구 대상을 국가무형문화재 종목들 중에서 일반인의 전승활동이 활발한 '아리랑'으로 선정하였다. 아리랑은 오랜 기간 제도권 밖에서 일반대중 활동을 중심으로 자생적으로 전승되었으며, 2015년에 전문전승자 지정 없이 국가무형문화재로 지정된 최초의 사례이다. 현재 아리랑은 약 60여 종, 3,600여 곡에 이르는 것으로 추정된다. 본 논문에서는 이 중에서 전문전승자와 일반전승자의 상호교류가 활발한 향토민요 '정선아리랑'을 중심으로 연구하였다. 소셜 네트워크 분석은 사람과 사람 사이의 관계를 노드(Node)와 링크(Link)로 모델링하여 수치화 통계화 시각화하여 해석하는 방법을 말한다. 이 방법은 전통적으로 사회학에서 사회조직 및 취약계층을 연구하는 데 꾸준히 활용되었다. 최근에는 문헌정보학, 문화콘텐츠학, 경영학 등과 같은 분야에서 연구경향, 시장동향, 조직관리 등을 연구하는 데 이 방법이 활용되고 있다. 이처럼 여러 학문 분야에서 소셜 네트워크 분석을 이용한 연구가 증가하는 추세지만 문화재 분야에서는 관련 연구를 찾아보기가 어렵다. 소셜 네트워크 분석은 크게 3단계, '연결망 모델링', '데이터 수집', '데이터 분석 및 시각화'로 진행된다. 본 논문에서는 첫 번째, 2017년 기준으로 정선아리랑보존회 회원 전체를 조사 대상으로 선정하여 완전한 연결망으로 모델링하였다. 두 번째, 데이터 수집은 보존회 회원 명부를 확보해 2017년 10월 17일 면대면 조사와 2017년 12월 15일 전화 설문조사를 통해 하였다. 세 번째, 데이터 분석은 Netminer 4.0 프로그램을 이용해 중심성 분석, 구조적 등위성 분석, 커뮤니티 분석 등을 주요 지표로 하였다. 본 논문은 기존에 무형문화유산 계보조사에서 소수 사람들의 구술자료에 의존해 파악하던 방식에서 벗어나 객관적이고 계량적인 방법으로 조사할 수 있는 기반을 제공하였다는 점에서 연구 의의가 있다. 그리고 무형문화유산 전승공동체 구성원들의 관계 및 지식 흐름의 구조를 지식지도(2D Spring Map) 형태로 시각화함으로써 추상적인 내용을 직관적으로 파악할 수 있게 했다는 점에서 의미가 있다.

권우(卷宇) 홍찬유(洪贊裕)(1915~2005)는 대한민국 근 현대 시기 대표적 한학자(漢學者)의 한 사람이자 시대의 지성인(知性人)으로, 학계의 후예들에 의해 사표(師表)로 추앙받고 있는 인물이다. 권우(卷宇)는 일제강점기와 한국전쟁, 독재와 민주화의 투쟁기라는 한국 사회의 지난한 혼란기를 몸소 겪으며 당대의 젊은 학자들을 교육하고 이끌었던 시대의 스승이었지만, 운명 이후 지금까지 그의 생애와 업적에 관한 학계의 조명이 이루어지지 않고 있다. 이 글은 아직까지 학계에서 논의되지 않았던 근 현대의 대표적 한학자 권우(卷宇) 홍찬유(洪贊裕)의 시문학 세계에 대해 살펴보고자 한 글이다. 그간 학계에서 논의되지 않았던 권우(卷宇) 홍찬유(洪贊裕)의 문집에 근거한 최초의 작업이고, 그에 대한 본격적인 탐구의 시작으로 최소한의 의미를 지닌다는 점에서, 이 글은 그의 문집 속 시문학 작품에 대한 세부적인 점검을 우선적인 목표로 삼는다. 그렇지만, 이와 같은 의도에도 불구하고 필자의 부족한 지식과 학문적 역량, 자료의 불비(不備)로 인해 이 글의 곳곳에서 한계가 노정될 수밖에 없다. 권우(卷宇)의 문집을 통해 본 권우(卷宇)의 시세계는 그의 시가 자신의 내적 정서의 표출을 시의 중심에 두고 있다는 특징을 보여준다. 이와 같은 특징은 권우(卷宇)가 지니고 있었던 시 의식이 시의 대사회적 효용보다 개인적 정서의 표출이라는 개인화에 보다 주목하는 것이었음을 말해준다. 이와 같은 권우(卷宇)의 시 의식은 그의 시문학 세계 전반에서 고르게 확인이 된다. 이에 따라 권우(卷宇)는 고시보다 근체시를, 연작시보다 단형시를 중심으로 하였으며, 송별시나 증여시 만시와 같은 대사회적 관계 속에서 이루어지는 시의 창작을 꺼렸다고 생각된다. 그런데 권우(卷宇)의 시문학 세계가 지니는 특성을 이렇게 정리하였을 때 몇 가지 의문점이 남게 된다. 우선적으로 지닐 수 있는 의문은 그의 문집 속 시문학 작품들이 그의 시세계 전부인가 하는 것이다. 현재 필자가 확인한 권우(卷宇)의 시문학 작품은 모두 문집 속에 수록되어 있는 것이지만, 권유의 시문학 세계가 이 작품들만으로 정리될 수 있는 것인가 하는 것에는 의문의 여지가 크다. 다음으로 지니게 되는 의문은 권우(卷宇)의 시문학 작품들이 내적 정서의 표출을 시의 중심에 두고 있으며, 흥(興)의 정서를 표출한 시와 감회(感懷)와 감개(感慨)의 정서를 표출한 시가 각기 다른 시문학 작품의 창작 공간과 상황에서도 동일한 모습으로 드러난다면, 각기 다른 성격의 흥취(興趣)와 감회(感懷) 감개(感慨)라는 정서를 시문학 작품 속으로 옮겨간 구체적인 창작 방법은 어떠한가 하는 것이다. 마지막 의문점은 만약 지금까지 문집을 통해 확인한 권우(卷宇)의 시문학 세계가 그의 시가 지니는 실상을 있는 그대로 보여주는 것이라고 한다면, 혹은 그의 생애 중 한 시기의 실상을 있는 그대로 보여주는 것이라고 한다면 그 의미는 무엇인가 하는 것이다. 이상과 같은 의문점은 권우(卷宇) 개인에 대한 탐색과 아울러 시대에 대한 탐색이 입체적으로 동시에 진행되어야 해소될 수 있을 것이라고 생각한다. 특히 권우(卷宇)의 시문학 세계에 대해 던지는 새로운 방향의 심화 연구 촉구는 근 현대 한문학사의 온전한 구성과 한문학사 한문학 연구의 연속성 확보를 위해서도 중요한 의미를 지닐 것이다. 이와 같은 점에서 앞으로 더 많은 연구자의 노력이 필요하리라 생각된다.

I. Introduction Since the 1970's drug abuse among young people has increasingly become a social problem in Korea. In the 1980's, drug abuse, especially glue sniffing, has become the cause of many unfortunated incidents resulting in harm to others as well as the abusers themselves. Taking into consideration of the seriousness of this problem, the Republic of Korea National Red Cross initiated a nation-wide research programme, to understand the present situation and to raise the level of public awareness. The goal of this research was to begin a nation - wide campaign against drug abuse. The research team was composed of the Advisary Committee members and the staff of the Youth Department of the Republic of Korea National Red Cross. The data were collected in February 1988 with the collaboration of the staff and volunteers in the local Chapters. The respondents were allocated nation-wide by the quota sampling method. The questionnaires were distributed to the respondents in three groups :2, 700 to junior and senior high school students, 605 to working youths, and 916 to delinquent youths. A total of 4, 221 questionnaires were collected. II. Characteristics of the Respondents The respondents in each group were selected evenly from rural and urban areas. The general characteristics of the respondents can be described as follow: in case of students, the proportions between male and female respondents, and between senior high school and junior high school students were almost evenly distributed. In case of working youths, the proportion of females (80.5%) was higher than those of the students and the delinquents groups. Delinquent youths were defined as those currently being under custody of the centers for juvenile delinquents. Of this number, 38.8% and 68.2% were junior and senior high school drop-outs respectively. The majority of them (92.6%) were male. As for the family background of the respondents, the proportion of those residing in poverty - stricken areas, and the proportion of those from broken families were higher in case of working youths and delinquent youths than those in case of students. III. Present Patterns of Drug Abuse The following summarizes the presents of drug abuse, as tabulated from the results of the survey. 1. Smoking The percentage of youths who smoke was 36% in the student group, 32% m the working youths group, and 94.4% in the delinquent youths group. 2. Alcohol 50.3% of students, 71.6% of working youths, and 93.3% of delinquent youths has experienced drinking alcohol beverages. 3. Tonic: non - alcoholic, caffeinated beverages popular in Korea and Japan The percentage of those who have used tonic at least once was over 90% in all of the three groups. 4. Sedative About 70% of each group has used sedative with the proportion of working youths use higher than those in other groups. 5. Stimulants Those who have used stimulants comprised around 15% in each group. 6. Tranquilizers Somewhat less than 5% of students and working youths, and 28% of delinquent youths, have used tranquilizers. 7. Hypnotics The users of hypnotics amounted to 0.4% of students, 2.6% of working youths and 7.1% of delinquent youths. 8. Marihuana Those who have used marihuana indicated 0.7% of students, 0.8% of working youths, and 13% of delinquent youths. 9. Glue-sniffing The percentage of glue-sniffing was 3.7%, 5% in the students group and in the youths group respectively, but the proportion was unusually high, at 40.7% in the delinquent youths group. From the results of the survey the present situation of drug abuse in Korea can be summarized as follows: 1. A high percentage of Korean youths have experienced smoking cigarettes and drinking alcoholic beverages. 2. Tonics (non - alcoholic, caffeinated beverages), antipyretic analgesics and stimulants quite regularly used. 3. Tranquilizers, hypnotics, marihuana and glue-sniffing are more widely used among delinquent youths than the other youths. From this fact, there exists a correlation between drug abuse and juvenile delinquency. IV. Time-series Analysis of the First Experience of Drug Abuse and Deviant Behaviour The respoundents were asked when they were first exposed to drugs and when they committed deviant acts. By calculating the average age of each experience, the following pattern was found (See Figure 1). Youths are first exposed to drugs by abuse of tonic(non - alcoholic, caffeinated beverages). At the age of 13, they amoke cigarettes, the use of antipyretic analgesics begins at 14 year old, while at the age of 15, they use tranquilizers, and at 16 hynotics. The period of drug abuse which starts from drinking caffeinated beverages and smoking cigarettes and ends in the use of hypnotics takes about three years. During this period, other delinquent behaviours begin to surface, that is, at the age of 13 when smoking cigarettes begins, the delinquent behaviour pattern starts with truancy. Next, they start taking money from others by using physical force. Prior to the age of 15, they are suspended from school, become hostile to adults, begin running away from home, and start using stimulants and alcohol. Soon they become involved even in glue-sniffing and in the use of marihuana. At the age of 15, they begin to see adult videos and carry weapons. Sexual promiscuity and usage of tranquilizers follows the viewing of adult videos. Consequently, by the time they reach the age of 16, they visit drinking establishments, and are picked up by police for committing delinquent acts. And finally, they come to use hypnotic - type drugs. From the above descriptions, drug abuse can be assumed to have a close correlation with delinquent behaviour. V. Social Factors Related to Drug Abuse As for the Korean youths, glue-sniffing is found to he related to aggressive delinquency, in such cases as run - aways, being picked up by the police, and taking money by force. Smoking cigarettes and drinking alcohol is found to be related to seeing adult videos and visiting drinking establishments. Hypnotics and marihuana were found to be representive of drugs which are related to degenerational delinquency, irrespective of social delinquency. The social factors connected with these drug abuse are as follows: 1. Individual factors Male students were more heavily involved in the usage of drug than females. Youths who do not attend church were more likely to be involved in drugs than those who attend. 2. Family factors The youths who were displeased with their mothers smoking and those who thought their parents did not love each other, or those whose parents had used drugs without prescription, were more likely to he drug users. 3. School factors Those youths who found school life boring, were unsuccessful in their studies, spend most of their time with friends, feel their teachers smoke too much, those who had a positive perception of their teachers smoking were likely to he drug users. To sum up, drug abusers depend on the influence of their parents, teachers and peers. IV. Reasons for Drug Abuse Korean students have mainly used drugs to release stress (42.8%), to stay awake (19.7%), and because of the easy accessibility of drugs( 16.6%). Other reasons are due to their ignorance of the side effects of the drugs (3.6%), natural curiosity (4.2%), and to increase strength(3.O%). From the above facts, the major reasons for drug abuse among Korean youths are to release stress and to stay awake in order to prepare exams. Furthermore, since drugs are readily available, we can conclude that drug abuse is caused by the school system(such as entrance exams) in Korea. VII. Conclusion Drug usage among Korean youths are relatively less common than those of western youths. In some cases, such as, glue-sniffing and use of stimulants, the pattern of drug abuse is found. Moreover, early drug abuse is evident, and it has a close connection with deviant behaviour, resulting in juvenile delinquency. Drug abuse cannot be attributed to any one social factor. Specifically, drug abuse depends on parents, peers, teachers and other members of the community, and also is influenced by social institutions such as the entrance exam system. Every person and organization concerned with youth must participate collectively in restraining drug abuse. Finally, it is suggested that social agencial working for youth welfare should make every effort to tackle this serious problem confronted by the Korean youths today.

신 부전 환자에게 발생하는 빈혈의 원인은 여러 가지가 있다. 그러나 rHuEPO를 투여할 시 이러한 요인들을 극복하고 빈혈을 교정할 수가 있다. 하지만 약 10%의 환자들에서는 고용량의 rHuEPO에도 불구하고 rHuEPO 저항성 빈혈을 나타낸다. 이러한 경우 DFO는 이러한 저항성을 극복할 수 있다고 하며, 이에 대한 기전은 아직 논란이 많다. 따라서 저자들은 DFO를 투여시 나타나는 여러 인자들을 고려해보고 기존의 보고보다 장기적인 관찰을 통하여 이러한 환자에게서 DFO가 빈혈을 교정할 수 있을지 여부를 알아보고 DFO가 rHuEPO 저항성 빈혈을 극복하는 기전을 추측해보고자 하였다. 영남대학교 의과대학 부속병원 투석실에서 투석을 시행하는 만성 신부전 환자 중 rHuEPO의 효과에 저항성을 나타내는 7명의 환자가 실험군(DFO+EPO)으로 정해지고, 다른 7명이 대조군으로 선정되었다. 실험군은 주당 4000 U의 고용량의 rHuEPO에도 불구하고 혈색소치가 9 g/dL이하 이며 출혈이나 철결핍성 빈혈같은 뚜렷한 원인 없이 정구성 정색소성 빈혈을 나타낸 환자들이었으며 대조군은 나이, 평균 투석 기간에 있어서 대조군과 차이를 보이지 않으며 rHuEPO에 비교적 적절한 반응을 보이는 환자들이었다. DFO는 8주간 rHuEPO와 함께 투여 되어 졌고 rHuEPO의 사용 용량은 지난 6개월의 평균 용량과 같게 투여 되었다(평균 사용 용량은 123.5 U/Kg/Wk). 8주간 DFO가 투여된 후 15 개월간 혈색소치와 rHuEPO 사용 용량을 추적하였다. 이 15개월간은 각 개인의 혈색소치와 경제 사정에 의해 rHuEPO의 용량이 결정지어 졌다. 대조군에서는 같은 기간 실험군에서와 같은 방법으로 rHuEPO가 투여되어 졌으나 DFO는 사용되지 않았다. DFO가 투여된 15 개월의 추적기간은 Time I(DFO투여후 7개월간)과 Time II(Time I 이후 8개월간)으로 나누었다. 성적은 다음과 같다: DFO 투여 전, 실험군의 평균 혈색소치는 대조군과(평균 8.2 g/dL) 같은 정도의(p>0.05) 수준인 7.8 g/dL 이었다. 하지만 rHuEPO의 사용 용량은 평균 123.5 U/Kg/Wk으로서 대조군의 그것(평균 41.6 U/Kg/Wk)보다 의미있게 많은(p<0.05) 용량을 사용하여 rHuEPO에 대한 저항성을 나타내었다. 하지만 DFO사용후 실험군에서 혈색소치는 의미있게 상승되었고(p<0.05) 이것은 Time II에 이르기까지 지속되었다(Time I; 평균 8.6 g/dL, Time II; 평균 8.6 g/dL). 즉, 혈색소치에 대한 DFO의 효과는 투여 후 15 개월간 Time I, Time II의 시기에 걸쳐 균등한 정도로 지속되었다. 또한 실험군에서 rHuEPO의 사용 용량은 DFO투여후 대조군과 유사한 수준으로 감소하였고 이것도 마찬가지로 15개월간 지속되었다(Time I; 평균 48.1 U/Kg/Wk. Time II; 평균 51.8 R/Kg/Wk. 한편, 같은 기간 대조군에서의 혈색소치와 rHuEPO사용 용량의 변화는 없었다. 특히, 실험군에서 혈색소치의 증가와 rHuEPO의 사용 용량의 감소는 DFO투여 후 1개월동안에 극대점을 이루었다. 즉, DFO 사용 후 감소된 rHuEPO사용 용량으로도 조혈 작용을 증강시킬 수 있었고 따라서 DFO를 사용함으로써 rHuEPO의 저항상을 극복할 수 있으리라고 생각된다. 보다 대규모의 실험과 잠재적으로 위험한 DFO의 부작용을 최소화 할 수 있는 적절한 용량과 투여 방법에 대한 연구가 더 필요하다고 사료된다.

We investigated what factors motivate gamers to participate in a guild and why they continue to be engaged as members of the guild. We find that, based on the result of focus group interviews with MMORPG gamers, social support and self-esteem factors play important roles. Considering both prior research and the focus group interviews we have conducted, we define social support and character control as independent variables. Character identity, guild identity, and self-esteem are proposed as mediating variables while guild flow and game loyalty as dependent variables. Accordingly, we develop the research model and hypotheses, and verify them empirically. Based on our experiences of playing the WoW game, we proposed a research model and conducted focus-group interviews (FGIs). FGIs involve formulating a hypothesis and then collecting some relevant data. FGIs were conducted face-to-face with students of C University in Korea. We formulated structured interview schedules, and the questions were based on our research variables and personal experiences. The questions for the interviews encompassed the following areas: (a) the demographic characteristics of the focus group; (b) the number of years for which respondents had played online games; (c) the motive for starting a game; (d) the number of game-characters assumed by each gamer; (e) the type of game played; and (f) other issues such as the reasons for involvement in the play, the willingness to reuse the game in case new versions were released, etc. On average, it took two hours to interview each of three groups. A primary set of FGIs was conducted with three groups on the premise that there would be some differences caused by character race (Horde vs. Alliance) or by playable server (Normal vs. Combat). With respect to the manner of playing, we found that guild members shared information, felt a sense of belonging, and played computer games for quite a long time through the guild; however, they did not undergo these experiences when playing alone. Gamers who belonged to a specific guild helped other players without expecting compensation for that, freely shared information about the game, gave away items for free, and more generous with other members who made mistakes. The guild members were aware of the existence other members and experienced a sense of belonging through interactions with, and evaluations from, other players. It was clear that social support was shown within the guild and that it played an important role as a major research variable. Based on the results of the first FGIs, a second set of in-depth FGIs was carried out with a focus on the psychology of the individual within the guild and the social community of the guild. The second set of FGIs also focused on the guild's offline meetings. Gamers, over all, recognize the necessity of joining a community, not only off-line but also online world of the guild. They admit that the guild is important for them to easily and conveniently enjoy playing online computer games. The active behavior and positive attitudes of existing guild members can motivate new members of the guild to adapt themselves to the guild environment. They then adopt the same behaviors and attitudes of established guild members. In this manner, the new members of the guild strengthen the bonds with other gamers while feeling a sense of belonging, and developing social identity, thereby. It was discovered that the interaction among guild members and the social support encouraged new gamers to quickly develop a sense of social identity and increase their self-esteem. The guild seemed to play the role of socializing gamers. Sometimes, even in the real world, the guild members helped one another; therefore, the features of the guild also spilled over to the offline environment. We intend to use self-esteem, which was found through the second set of FGIs, as an important research variable. To collect data, an online survey was designed with a questionnaire to be completed by WoW gamers, who belong to a guild. The survey was registered on the best three domestic game-sites: 'WoW playforum,' 'WoW gamemeca,' and 'Wow invent.' The selected items to be measured in the questionnaire were decided based on prior research and data from FGIs. To verify the content of the questionnaire, we carried out a pilot test with the same participants to point out ambiguous questions as a way to ensure maximum accuracy of the survey result. A total of 244 responses were analyzed from the 250 completed questionnaires. The SEM analysis was used to test goodness-of-fit of the model. As a result, we found important results as follows: First, according to the statistics, social support had statistically significant impacts on character control, character identity, guild identity and self-esteem. Second, character control had significant effects on character identity, guild identity and self-esteem. Third, character identity shows its clear impact on self-esteem and game loyalty. Fourth, guild identity affected self-esteem, guild flow and game loyalty. Fifth, self-esteem had a positive influence on the guild flow. These days, the number of virtual community is rising along with its significance largely because of the nature of the online games. Accordingly, this study is designed to clarify the psychological relationship between gamers within the guild that has been generally established by gamers to play online games together. This study focuses on the relationships in which social support influences guild flow or game loyalty through character control, character identity, guild identity, and self-esteem, which are present within a guild in the MMORPG game environment. The study results are as follows. First, the effects of social support on character control, character identity, guild identity and self-esteem are proven to be statistically significant. It was found that character control improves character identity, guild identity and self-esteem. Among the seven variables, social support, which is derived from FGIs, plays an important role in this study. With the active support of other guild members, gamers can improve their ability to develop good characters and to control them. Second, character identity has a positive effect on self-esteem and game loyalty, while guild identity has a significant effect on self-esteem, guild flow and game loyalty. Self-esteem affects guild flow. It was found that the higher the character and guild identities become, the greater the self-esteem is established. Contrary to the findings of prior research, our study results indicate that the relationship between character identity and guild flow is not significant. Rather, it was found that character identity directly affects game players' loyalty. Even though the character identity had no direct effect on increasing guild flow, it has indirectly affected guild flow through self-esteem. The significant relationship between self-esteem and guild flow indicates that gamers achieve flow, i.e., a feeling of pleasure and excitement through social support. Several important implications of this study should be noted. First, both qualitative and quantitative methods were used to conduct this study. Through FGIs, it was observed that both social support and self-esteem are important variables. Second, because guilds had been rarely studied, this research is expected to play an important role in the online community. Third, according to the result, six hypotheses (H1, H5, H6, H7, H8, and H11) setup based on FGIs, were statistically significant; thus, we can suggest the corresponding relationships among the variables as a guideline for follow-up research. Our research is significant as it has following implications: first, the social support of the guild members is important when establishing character control, character identity, guildidentity and self-esteem. It is also a major variable that affects guild flow and game loyalty. Second, character control when improved by social support shows notable influence on the development of character identity, guild identity and self-esteem. Third, character identity and guild identity are major factors to help establish gamers' own self-esteem. Fourth, character identity affects guild flow through self-esteem and game loyalty. The gamers usually express themselves through characters; the higher character identity is, the more loyalty a gamer has. Fifth, guild identity, established within the guild, has clear effects on self-esteem, guild flow and game loyalty. Sixth, qualitative and quantitative methods are employed to conduct this study. Based on the results of focus group interviews and SEM analysis, we find that the social support by guild members and psychological factors are significant in strengthening the flow of guild and loyalty to the game. As such, game developers should provide some extra functions for guild community, through which gamers can play online games in collaboration with one another. Also, we suggest that positive self-esteem which is built up through social support can help gamers achieve higher level of flow and satisfaction, which will consequently contribute to minimizing the possibility for the players to develop negative attitude toward the guild they belong to.
