  • 본 논문은 함정용 LED 조명기구의 전기적, 광학적 요구사항을 제시하고 실증으로 요구사항 만족여부를 확인하였으며, 2012년 함정에 최초 적용된 이후 현재까지 비용 효과를 분석하였다. 함정용 LED 조명기구의 요구사항을 도출하기 위하여 한국산업규격(KS), 국방규격(KDS) 및 미 해군규격(MIL)의 요구사항을 비교하여 함정용 LED 조명기구의 요구사항을 제시하였다. 형광등기구와 LED 조명기구의 전기적 특성과 광학적 특성을 실험으로 분석하여 요구사항 적용 타당성을 검증하였고, 제시된 함정용 LED 조명기구의 요구사항으로 A1함정에 주 조명등으로 설치되었다. LED 조명기구로 설치된 이후 형광등에 비해 소비전력은 약 40% 감소되었고, 광속은 10 ~ 15% 증가하였다. 또한, 2012년에서 2015년까지 함정 10척에서 약 4,900개의 형광등기구가 감소되는 효과가 있었고, 약 5.6억원의 절감효과를 확인하였다. 향후 지속적으로 함정에 LED 조명기구를 설치하고 있어 많은 절감효과가 기대된다.

  • Purpose - Recently, as Korean culture and economy develops, Seoul has become a world-famed city. In Seoul, many special grade hotels have been constructed in order to accommodate many tourists from China, Japan and many other Asian countries. And the hotels entered into competition among themselves. Thus many changes are accelerated due to their mutual competition and manpower problems. In this situation, the role of higher officers above all is thought to be very important in order to enhance the management result and to make preparations for the kernel ability of the organization. Research design, data and methodology - This study was intended to verify how the leadership of the higher officers based on trust affects the job satisfaction of employees of the organization. In order to achieve the purpose of this study, some study models and hypotheses have been established through theoretical examinations. The subjects of this study were centered on the constituents of C-Hotel, M-Hotel, and D-Hotel. 200 questionaries were distributed and 190 questionaries were collected and thus the collection ratio was 91 percent. 8 questionaries which were regarded to be insincere or hard to analyzed were excluded. Finally, 182 questionaries were used for analyzing the factors and trust. For the purpose of the verification of hypotheses, structural equation was used. In order to verify the mediating effect of trust between the relationship of emotional leadership and job satisfaction, 'Three-step Mediated Regression Analysis by Baron & Kenny(1986) was utilized. The four hypotheses for this study are as follows: First, emotional leadership will have a meaningful influence on trust in the affirmative. Second, trust will have a meaningful influence on job satisfaction in the affirmative. Third, trust will play a mediating role in the relationship of emotional leadership and job satisfaction. Result - First, the emotional leadership and trust was found to effect a positive effect. Second, the trust and job satisfaction was found on a positive effect on job satisfaction. Third, the emotional leadership and job satisfaction was found to positive effect on job satisfaction. Fourth, the trust in the relationship between emotional leadership and job satisfaction was found that the partial mediating effect. Especially, in the case of the business of hospitality, human services as well as material resources become its keynote, and we can safely say that the degree of dependence toward human resources is very high. Accordingly, the leaders should display their leadership on the basis of abundant emotional and intellectual faculties so that they can grasp, understand and admit the diverse views of value and emotion of the organization constituents and that they can form emotional leadership. On the basis of the analysis results of the verification of hypotheses, some suggestions and uppermost limit of this study have been presented for further study.

  • Objective : To analyze the effects of the number and shape of fenestrations on the mechanical strength of pedicle screws and the effects of bone cement augmentation (BCA) on the pull-out strength (POS) of screws used in conventional BCA. Methods : For the control group, a conventional screw was defined as C1, a screw with cannulated end-holes was defined as C2, a C2 screw with six pinholes was defined as C3, and the control group type was set. Among the experimental screws, T1 was designed using symmetrically placed thru-hole type fenestrations with an elliptical shape, while T2 was designed with half-moon (HM)-shaped asymmetrical fenestrations. T3 and T4 were designed with single HM-shaped fenestrations covering three pitches and five pitches, respectively. T5 and T6 were designed with 0.6-mm and 1-mm wider fenestrations than T3. BCA was performed by injecting 3 mL of commercial bone cement in the screw, and mechanical strength and POS tests were performed according to ASTM F1717 and ASTM F543 standards. Synthetic bone (model #1522-505) made of polyurethane foam was used as a model of osteoporotic bone, and radiographic examinations were performed using computed tomography and fluoroscopy. Results : In the fatigue test, at 75% ultimate load, fractures occurred 7781 and 9189 times; at 50%, they occurred 36122 and 82067 times; and at 25%, no fractures occurred. The mean ultimate load for each screw type was 219.1±52.39 N for T1, 234.74±15.9 N for T2, 220.70±59.23 N for T3, 216.45±32.4 N for T4, 181.55±54.78 N for T5, and 216.47±29.25 N for T6. In comparison with C1, T1, T2, T3, T4, and T6 showed significantly different ultimate load values (p<0.05). However, when the values for C2 and the fenestrated screws were evaluated with an unpaired t test, the ultimate load value of C2 significantly differed only from that of T2 (p=0.025). The ultimate load value of C3 differed significantly from those of T1 and T2 (C3 vs. T1 : p=0.048; C3 vs. T2 : p<0.001). Linear correlation analysis revealed a significant correlation between the fenestration area and the volume of bone cement (Pearson's correlation coefficient r=0.288, p=0.036). The bone cement volume and ultimate load significantly correlated with each other in linear correlation analysis (r=0.403, p=0.003). Conclusion : Fenestration yielded a superior ultimate load in comparison with standard BCA using a conventional screw. In T2 screws with asymmetrical two-way fenestrations showed the maximal increase in ultimate load. The fenestrated screws can be expected to show a stable position for the formation of the cement mass.

  • The purpose of this study was to investigate the real condition of hospital marketing and concrete strategy on medical consumers need for enhance the effectiveness of hospital management. The data were collected from January 27 to February 3, 2000 at a general hospital located in M city to 205 in-patients and out-patients by questionnaires. The research tool was based on literatures. The data was analysed by the use of percentage, mean, t-test and ANOVA by SAS(Statistical Analysis System) Package Program. The results of this study are summerized as follows: 1. Mean score of the marketing mix (4P 's) was 3.1 in total and each mean score was 3.6 in product, 2.5 in prices, 3.3 in place and 3.1 in promotion. The following are the items which received the highest scores in each: 'The hospital is clean' in service category; 'the prices of meals at the restaurant the patients' families use are reasonable ' in price sphere. In distribution, 'it is easy to locate the hospital' and in promotion,'we'll use this hospital again' and 'we'll recommend this hospital to others'. 2. Marketing mix factors(4P's) was significantly different on the general characteristics in terms of marriage status, occupations and the period of hospitalization. 3. The most important reason for choosing this hospital was 'This is a general hospital with good facilities' and the next were 'The hospital staffs are kind and the hospital is clean' and 'The traffic is convenient to come'. The most important factors contributing to a good image formation of the hospital were 'this is a clean hospital', 'This is a hospital with kind people' and 'this hospital is equipped with good medical facilities'. 4. The factors for making a good image concerning the nursing service were professional knowledge, good nursing skills and kindness. After grasping the marketing conditions of the hospital aided by the above-mentioned research results, the researchers concludes that it is necessary to develop an institutionalized service strategy to increase the satisfaction the patients feel about the hospital facilities and kindness of the staff and as a result, to differentiate it from other medical institutions.

  • 본 연구는 약물의 작용기전이 각기 다른 methylphenidate와 imipramine을 투여하여 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애(過剩運動障碍)(attention deficit-hyperactivity disorder : ADHD)아동에서 부모와 교사의 평정척도(平定尺度)로 행동변화를 그리고 신경심리학적검사(神經心理學的檢査)로 주의력(注意力)과 인지기능(認知機能)을 측정하여 두 약물이주는 영향이 행동영역(行動領域)과 인지기능(認知機能)에서 어떻게 다르게 나타나는 지를 비교검토해 본 것이다. 저자들은 미국정신의학회 정신질환 진단기준편람 개정3판(DSM-III-R)에 의거하여 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애(過剩運動障碍)로 진단받은 생후 만 5년 6개월부터 12년 1개월사이의 남아 30명을 대상으로 이들의 임상적${\cdot}$의학적 특성을 조사하고, 지능검사를 포함한 신경심리학적검사(神經心理學的檢査)를 시행한 뒤, 부모(父母) 및 교사용(敎師用) 평정척도(評定尺度)로 이들의 행동을 평가하였다. 그리고 평가된 아동을 무작위로 15명씩 두 집단으로 나누어 각각 methylphenidate($0.5{\sim}0.6mg/kg)$와 imipramine(25${\sim}100mg$)을 경구투여(經口投與)하고, 투여 1개월후 및 2개월후에 각 1회씩 다시 부모와 교사들에게 같은 평정척도(評定尺度)로 이들의 행동을 평가시키고 아울러 지능검사(知能檢査)를 제외한 모든 신경심리학적검사(神經心理學的檢査)를 시행하였다. 그 결과를 보면 imipramine을 투여받은 아동들은 투여 1개월후 아동행동조사표(兒童行動調査表)(CBCL)의 외상성(外商性)과 과잉행동(過剩行動)${\cdot}$사회적위축요인(社會的萎縮要因)에서 호전을, 그리고 2개월후에는 학교상황질간지(學校狀況質間紙), 코너스씨(氏) 단축형 교사평정척도(短縮形 敎師平定尺度)(CATRS) 및 연속과제수행(連續課題遂行)(CPT)에서 호전을 보였다. 반면 methylphenidate를 투여받은 아동들은 투여 1개월후 부터 부모가 평가하는 코너스씨(氏) 단축형 부모평정척도(短縮形 父母平定尺度)(CAPRS), 아동행동조사표(兒童行動調査表) 및 연속과제수행(連續課題遂行)에서 호전을 보였고, 투여 2개월후에서도 같은 양상의 호전을 보였으며, 또한 아동행동조사표(兒童行動調査表)에서 외향성(外向性)은 물론 소통불능(疏通不能)${\cdot}$사회적위축(社會的萎縮)${\cdot}$과잉행동(過剩行動)${\cdot}$공격성(攻擊性)${\cdot}$비행요인(非行要因)에서도 호전양상을 보였다. 이와같은 결과는 이 두 약물이 모두 주의력(注意力)과 인지기능(認知機能)을 증진시키기는 하였으나, 보다 뚜렷한 변화는 methylphenidate 투여후에 볼 수 있었다. 특히 methylphenidate투여후 연속과제수행(連續課題遂行)에서 민감도(敏感度)와 반응오류수(反應誤謬數)의 호전이 있었으나 반응기준(反應基準)에는 변화가 없었다는 소견, 그리고 단기기억수행(短期記憶遂行)에서의 호전과 '같은 그림 찾기' 검사의 오류수(誤謬數)에서 변화가 없었다는 소견은 methylphenidate가 훈기요인(勳機要因)의 호전에 의한 이차적인 변화에 의한 것이 아니라 주의집중력(注意集中力)에 직접적으로 효과를 나타내는 것으로 해석할 수 있었다. 또한 이같은 소견으로 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애환아(過剩運動障碍患兒)에서의 충동성(衝動性)은 이 장애의 중심증상이 아니거나, 이들 약물투여에 의해 호전되지 않거나, 호전의 측정에 문제가 있을 수도 있겠다. 마지막으로 주의력결핍(注意力缺乏)${\cdot}$과잉운동장애(過剩運動障碍)에서 과잉행동(過剩行動)과 주의력결핍(注意力缺乏)이 서로 다른 신경전달체계(神經傳達體系)를 통해서 나타날 가능성에 대해서도 논의하였다.

  • 전세계적으로 기후변화로 인한 그린인프라와 환경기반시설의 영향 및 예측에 대한 연구는 활발히 진행되고 있다. 하지만 국가별 극한기후가 발생하는 시기나 패턴이 다르기에 국내에도 극한기후로 인한 그린인프라와 환경기반시설에 대한 연구가 필요하다. 따라서 본 연구에서는 국내 주요 7개 도시를 대상으로 기상청에서 제공하는 20년 동안의 극한기후에 대한 통계적 분석과 극한기후로 인한 자연기반해법(NBS)을 적용한 그린인프라 시설에 대한 영향분석을 수행하였다. 극한기후에 대한 통계분석 결과 지리적 위치, 지표 불투수성, 지역 기상 패턴에 따라 다양한 극한 기상조건에 잠재적으로 취약한 것으로 분석되었다. 서울은 극한온도(영상, 영하)가 관측되었으며 부산, 울산 및 제주에서는 강수량과 바람에 대해 극한기후가 발생하여 도시탄력성에 잠재적인 위협인자로 분류되었다. 온도는 도시 내 식생에 대한 회복력에 주요 요인으로 적용되며, 바이오차, 모래, 자갈, 우드칩 등 여재를 적용한 습지(CW)에서 극 영하온도에서 물리적 제거효율 및 영양염류 제거능력을 저하되는 것으로 분석되었다. 극한기후로 인한 영향을 저감하기 위해 그린인프라 시설 내 온도조절이 가능한 차광 및 단열 시스템적용과 같은 극한기후 별 대응전략 수립이 가능하다. 본 연구를 통해 국내와 기후특성이 유사한 지역에서의 극한기후 대응전략 수립에 도움이 될 것으로 판단된다.

  • Purpose: This study was conducted to evaluate the effectiveness of the treatment strategy of transcatheter arterial embolization after pelvic CT angiography (CTA) in cases of traumatic pelvic hemorrhage. Methods: This is a retrospective analysis of pelvic hemorrhage patients who underwent transcatheter arterial embolization after pelvic CTA at our regional emergency center during a 31-month period. We reviewed the medical records and imagings of all these patients. Results: Transcatheter arterial embolization was performed in 17 patients (M:F=7:10, mean age=53.9) who underwent pelvic CTA for the evaluation of traumatic pelvic hemorrhage. Arterial bleeding was demonstrated on pelvic CTA in all patients, and the combined injury was also noted in 13 patients. The admission-to-CTA time was $84.53{\pm}66.92$ minutes, and the CTA-to-embolization time was $147.65{\pm}99.97$ minutes. Extravasation of contrast media or pseudoaneurysm was demonstrated on conventional angiography in all patients. Unilateral iliac artery embolization was performed in 8 patients, and bilateral iliac artery embolization was performed in 9 patients. Additional embolizations other than in the iliac arteries were performed in 7 patients. Initial hemostasis was achieved in 16 patients. One patient died of ongoing pelvic bleeding. Rebleeding occurred in only one patient and hemostasis was achieved with the second embolization. Another patient died of intracranial and facial bleeding in spite of pelvic hemostasis. The overall mortality was 11.8%, and there was no significant adverse effects in the other patients. Conclusion: Transcatheter arterial embolization after pelvic CTA is an effective treatment strategy in the management of traumatic pelvic hemorrhage patients.

  • The success of the family planning program in Korea is reflected in the decrease in the growth rate from 3.0% in 1962 to 2.0% in 1971, and in the decrease in the fertility rate from 43/1,000 in 1960 to 29/1,000 in 1970. However, it would be erroneous to attribute these reductions entirely to the family planning program. Other socio-economic factors, such as the increasing age at marriage and the increasing use of induced abortions, definitely had an impact on the lowered growth and fertility rate. Despite the relative success of the program to data in meeting its goals, there is no room for complacency. Meeting the goal of a further reduction in the population growth rate to 1.3% by 1981 is a much more difficult task than any one faced in the past. Not only must fertility be lowered further, but the size of the target population itself will expand tremendously in the late seventies; due to the post-war baby boom of the 1950's reaching reproductive ages. Furthermore, it is doubtful that the age at marriage will continue to rise as in the past or that the incidence of induced abortion will continue to increase. Consequently, future reductions in fertility will be more dependent on the performance of the national family planning program, with less assistance from these non-program factors. This paper will describe various approaches to help to the solution of these current problems. 1. PRACTICE RATE IN FAMILY PLANNING In 1973, the attitude (approval) and knowledge rates were quite high; 94% and 98% respectively. But a large gap exists between that and the actual practice rate, which is only 3695. Two factors must be considered in attempting to close the KAP-gap. The first is to change social norms, which still favor a larger family, increasing the practice rate cannot be done very quickly. The second point to consider is that the family planning program has not yet reached all the eligible women. A 1973 study determineded that a large portion, 3096 in fact, of all eligible women do not want more children, but are not practicing family planning. Thus, future efforts to help close the KAP-gap must focus attention and services on this important large group of potential acceptors. 2. CONTINUATION RATES Dissatisfaction with the loop and pill has resulted in high discontinuation rates. For example, a 1973 survey revealed that within the first six months initial loop acceptance. nearly 50% were dropouts, and that within the first four months of inital pill acceptance. nearly 50% were dropouts. These discontinuation rates have risen over the past few years. The high rate of discontinuance obviously decreases the contraceptive effectiveness. and has resulted in many unwanted births which is directly related to the increase of induced abortions. In the future, the family planning program must emphasize the improved quality of initial and follow-up services. rather than more quantity, in order to insure higher continuation rates and thus more effective contraceptive protection. 3. INDUCED ABORTION As noted earlier. the use of induced abortions has been increase yearly. For example, in 1960, the average number of abortions was 0.6 abortions per women in the 15-44 age range. By 1970. that had increased to 2 abortions per women. In 1966. 13% of all women between 15-44 had experienced at least one abortion. By 1971, that figure jumped to 28%. In 1973 alone, the total number of abortions was 400,000. Besides the ever incre.sing number of induced abortions, another change has that those who use abortions have shifted since 1965 to include- not. only the middle class, but also rural and low-income women. In the future. in response to the demand for abortion services among rural and low-income w~men, the government must provide and support abortion services for these women as a part of the national family planning program. 4. TARGET SYSTIi:M Since 1962, the nationwide target system has been used to set a target for each method, and the target number of acceptors is then apportioned out to various sub-areas according to the number of eligible couples in each area. Because these targets are set without consideration for demographic factors, particular tastes, prejudices, and previous patterns of acceptance in the area, a high discontinuation rate for all methods and a high wastage rate for the oral pill and condom results. In the future. to alleviate these problems of the methodbased target system. an alternative. such as the weighted-credit system, should be adopted on a nation wide basis. In this system. each contraceptive method is. assigned a specific number of points based upon the couple-years of protection (CYP) provided by the method. and no specific targets for each method are given. 5. INCREASE OF STERILIZA.TION TARGET Two special projects. the hospital-based family planning program and the armed forces program, has greatly contributed to the increasing acceptance in female and male sterilization respectively. From January-September 1974, 28,773 sterilizations were performed. During the same time in 1975, 46,894 were performed; a 63% increase. If this trend continues, by the end of 1975. approximately 70,000 sterilizations will have been performed. Sterilization is a much better method than both the loop and pill, in terms of more effective contraceptive protection and the almost zero dropout rate. In the future, the. family planning program should continue to stress the special programs which make more sterilizations possible. In particular, it should seek to add the laparoscope techniques to facilitate female sterilization acceptance rates. 6. INCREASE NUMBER OF PRIVATE ACCEPTORS Among the current family planning users, approximately 1/3 are in the private sector and thus do not- require government subsidy. The number of private acceptors increases with increasing urbanization and economic growth. To speed this process, the government initiated the special hospital based family planning program which is utilized mostly by the private sector. However, in the future, to further hasten the increase of private acceptors, the government should encourage doctors in private practice to provide family planning services, and provide the contraceptive supplies. This way, those do utilize the private medical system will also be able to receive family planning services and pay for it. Another means of increasing the number of private acceptors, IS to greatly expand the commercial outlets for pills and condoms beyond the existing service points of drugstores, hospitals, and health centers. 7. IE&C PROGRAM The current preferred family size is nearly twice as high as needed to achieve a stable poplation. Also, a strong boy preference hinders a small family size as nearly all couples fuel they must have at least one or more sons. The IE&C program must, in the future, strive to emphasize the values of the small family and equality of the sexes. A second problem for the IE&C program to work. with in the: future is the large group of people who approves family planning, want no more children, but do not practice. The IE&C program must work to motivate these people to accept family planning And finally, for those who already practice, an IE&C program in the future must stress continuation of use. The IE&C campaign, to insure highest effectiveness, should be based on a detailed factor analysis of contraceptive discontinuance. In conclusion, Korea faces a serious unfavorable sociodemographic situation- in the future unless the population growth rate can be curtailed. And in the future, the decrease in fertility will depend solely on the family planning program, as the effect of other socio-economic factors has already been maximumally felt. A second serious factor to consider is the increasing number of eligible women due to the 1950's baby boom. Thus, to meet these challenges, the program target must be increased and the program must improve the effectiveness of its current activities and develop new programs.

  • 체내 면역 증강정을 관찰하기 위하여 체내 임파구의 활성 및 증가 여부를 3개월간 의뢰한 물질인 Immu-Forte EX, Immu-Forte 된장고추장, Immu-Forte A, Immu-Forte를 투여한 후, flowcyometry 및 sandwitch ELISA를 이용하여 측정하였다. 본 실험의 실험 기간 중에 동물의 질병이나 감염에 의한 면역학적인 변화가 있었는지를 확인하기 위하여 혈액학적인 검사를 실시하였으며, 혈액학적인 검사에서 Alkaline phosphatase, T protein, Albumin, Creatine, ALT, AST, Total bilirubin, Potasium을 검사해 본 결과 대조군과 비교 했을때 투여군 전군에서 정상적인 범위내 수치를 나타내는 것으로 나타났다. 이러한 결과로부터 본 실험에서 나온 결과는 질병이나 감염에 의한 것이 아닌 생체내에서의 면역성 증강에 의한 것으로 판단할수 있는 근거를 제공한다고 판단되어진다. 한편, 3개월간 장기 투여시 Immu-Forte EX, Immu-Forte 된장고추장, Immu-Forte A과 Immu-Forte 의 모든 물질은 전반적으로 면역 세포와 사이토카인의 수치를 유의적으로 증가시켰다 그러나, 3개월간 Immu-Forte EX를 투여 후 혈중콜레스테롤 수치를 검사해 본 결과 대조군$(118\pm24.4 mg/dL)$과 비교하였을때, 고용량$(126\pm7.7 mg/dL)$, 중간용량$(121\pm8.4 mg/dL)$, 저용량$(109\pm24.Smg/dL)$으로서 통계학적인 유의적 감소로는 보이지 않는다. 각각의 물질의 면역학적인 변화양상을 살펴보면 물질 동암 EX는 중간 농도군에서는 CD4 T 림파구, CD8 림파구, 대식세포, IL-12, IFN-r가 대조군에 비해서 유의적으로 증가했으며 떠농도에서는 전체 T 임파구, 전체 B 임파구, CD4 T 임파구, 대식세포, IL-2, IL4, IL-12가 대조군에 비해서 유의적으로 증가했다. 물질 Immu-Forte 된장고추장에서는 고농도에서는 CD4 T 임파구, IL-2, IL-4, IL-12가 유의적으로 증가했으며, 중간농도에서는 CD4 임파구, 대식세포, IL-2,IL-4,IL-12 가 유의적으로 증가했고, 저농도에서는 전체 T 임파구, CD4 T 임파구, IL-2, IL-4, IL-12가 유의적으로 증가했다. 물질 Immu-Forte A의 경우 고농도에서 대식세포,자연살해세포, IL-12가 중간농도에서는 전체 T임파구, CD4 T임파구, 대식세포, 자연살해세포, IL-2, IL-4, IL-12가 저농도에서는 자연살해세포가 유의적으로 증가했다. 물질 Immune-Forte f의 경우 고농도에서 전체 B 임파구, IL-4, IL-12가 중간농도에서 전체 T임파구, 전체 B임파구, CD4 T임파구, CD8 T 임파구, 대식세포, IL-2, IL-4, IL-12, IFN-r가 저농도에서는 자연살해세포, IL-12가 유의적으로 증가하였다. 이상과 같이 각각의 물질은 전반적으로 면역증강 효과가 있는 것으로 나타났으며 그 면역증강을 유도하는 세포나 사이토카인은 서로 정확히 일치하지 않는 것으로 보아 각각의 물질이 다른 기전을 통해서 면역증강을 유도하는 것으로 생각된다.
