  • Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.

  • 일사량은 작물 생산성 평가를 위한 작물 생육 모델의 주요 입력 변수 중 하나로 사용되지만 관측이 어려워 다른 기상 변수들에 비해 관측값의 확보가 어렵다. 천리안 2A호와 히마와리 8호 위성 일사량 자료가 제공되기 시작하면서, 작물 생육과 태양광 발전을 결합한 영농형 태양광 시설 하에서의 작물 생산성 평가를 위한 일사량 자료를 확보하기 용이해졌다. 본 연구의 목적은 이들 인공위성 일사량 자료의 신뢰도를 비교하는 것이다. 이를 위해 2020년 5월부터 10월까지 인공위성 일사량 자료를 수집하여 일별 일사량의 평균 제곱근 편차(RMSE)와 정규 평균 제곱근 편차(NRMSE)를 계산하였다. 인공위성 일사량 자료가 작물 생육 모의 결과의 신뢰도에 미치는 영향을 파악하기 위해 연구기간 동안의 일사량 누적값을 비교하였다. 본 연구의 결과 히마와리 8호 일사량 자료가 천리안 2A호 일사량 자료보다 RMSE와 NRMSE가 작은 것으로 나타났다. 누적 일사량을 비교한 결과에서도 히마와리 8호 일사량 자료 누적값이 천리안 2A호 일사량 자료 누적값보다 오차가 작았다. 본 연구의 결과는 작물 생산성 평가에 히마와리 8호 일사량 자료를 사용하는 것이 천리안 2A호 일사량 자료를 사용하는 것보다 불확도를 줄일 수 있다는 것을 시사한다. 후속 연구에서 히마와리 8호 일사량 자료를 사용한 영농형 태양광 시설 하에서의 작물 생산성 및 태양광 발전량에 대한 분석이 이루어져야 할 것이다.

  • 급격한 도시화를 겪으면서 자연적인 물순환 체계의 왜곡을 초래하였다. 이러한 물순환 구조의 변화는 기존 수자원 이용 경향을 변화시키며 하천 건천화 현상을 유발하고 있다. 이를 관리하기 위해 건천화 평가 및 예측이 가능한 하천 건천화 영향 평가 기술이 필요하다. 하천 건천화 영향평가 기술 수행을 위해서는 기초자료로써 GIS 기반의 공간자료 구축이 필수적이나, 관련 연구는 미흡한 실정이다. 따라서 본 연구에서는 하천 건천화 평가를 위한 GIS 기반의 시계열 공간자료 활용에 대한 연구를 수행하였다. 이에 6개 하천 건천화 영향요소(기상, 토심, 산림밀도 및 높이, 도로망, 지하수 이용량, 토지이용)을 대상으로, 과거 수십년 간의 변화과정을 전국 단위 GIS 자료로 구축하여 연속수문모형 운용에 대한 기초자료로 활용하였다. 이러한 영향요소를 대상으로 시계열에 따라 하천 건천화 원인을 분석하고 해석할 수 있는 분포형 연속수문모형 기반의 DrySAT을 활용하여 하천 건천화 영향요소별 연유출량 및 건천화 평가를 수행하였다. 그 결과, 다른 요소들은 고려하지 않고 주어진 기상 조건하에 연유출량은 기본값 977.9mm로 산출되었다. 반면, 토심 감소, 산림 높이 증가, 도로 개발 증가, 지하수이용량 증가, 토지이용 개발변화를 고려하였을 때의 연평균 유출량은 각각 1,003.5mm, 942.1mm, 961.9mm, 915.5mm, 1003.7mm로 산출되었다. 산출된 결과는 하천건천화의 주요 원인으로서 지표유출량을 증가시켜 하천유량을 감소시키는 토심의 감소, 지표유출량을 감소시키는 산림 밀도의 증가, 지표하유출량을 감소시키는 도로의 증가, 기저유출량을 감소시키는 무분별한 지하수 개발과 지하수이용량의 증가, 지표유출량을 증가시키는 불투수지역의 증가를 들 수 있다. 또한, 하천 건천화 정의 및 등급 범위를 통해서 건천화 등급에 따라 표준유역별로 나타내었으며, 기상, 토심 감소 고려, 산림 높이 증가, 도로 개발 증가, 지하수이용량 증가, 토지이용 개발변화를 고려하였을 때의 건천화 등급은 각각 2.1, 2.2, 2.5, 2.3, 2.8, 2.2로 나타났다. 기본값인 강우조건을 제외한 5개 하천 건천화 영향요소에 대한 건천화 영향순위는 지하수 이용량 변화에 대한 건천화 영향이 제일 컸으며, 산림 밀도 변화, 도로 건설 변화, 토지이용 변화 및 토심 변화 순으로 나타났다. 향후 전국 하천 건천화 평가시스템 개발을 통해 6개 하천 건천화 영향요소에 대한 미래 자료 변화 및 이에 대한 건천화의 진행전망 등 시스템에 의한 평가결과를 토대로 맞춤형 하천 건천 관리 및 방지 방안을 제공할 수 있을 것으로 판단된다.

  • The research conducted here focuses on the effect of factors that affect the behavior of UCC (User Created Content) website users, other than user's rational recognition of how useful a UCC website can be. Most discussions in the existing literature on information systems have focused on users' evaluation how a UCC website can help to attain the users' own goals. However, there are other factors and this research pays attention to an individual's 'personality,' which is stable and biological in nature. Specifically, I have noted here that 'extroversion' and 'neuroticism,' the two common personality factors presented in Eysenck's most representative 'EPQ Model' and 'Big Five Model,' are the two personality factors that affect a site's 'usefulness,' by this I mean how useful does the user consider the website and its content. How useful a site is considered by the user is the other factor that has been regarded as the antecedent factor that influences the adoption of information systems in the existing MIS (Management Information System) research. Secondly, as using or creating a UCC website does not guarantee the user's or the creator's extrinsic motivation, unlike when using the information system within an organization, there is a greater likelihood that the increase in user's activities in relation to a UCC website is motivated by emotional factors rather than rational factors. Thus, I have decided to include the relationship between an individual's personality and what they find pleasurable in the research model. Thirdly, when based on the S-O-R Paradigm of Mehrabian and Russell, the two cognitive factors and emotional factors are finally affected by stimulus, and thus these factors ultimately have an effect on an individual's respondent behavior. Therefore, this research has presented an assumption that the recognition of how useful the site and content is and what emotional pleasure it provides will finally affect the behavior of the UCC website users. Finally, the relationship between the recognition of how useful a site is and how pleasurable it is to useand UCC usage may differ depending on certain situational conditions. In other words, the relationship between the three factors may vary according to how much users are involved in the creation of the website content. Creation thus emerges as the keyword of UCC. I analyzed the above relationships through the moderating variable of the user's involvement in the creation of the site. The research result shows the following: When it comes to the relationship between an individual's personality and what they find pleasurable it is extroverted users who have a greater likelihood to feel pleasure when using a UCC website, as was expected in this research. This in turn leads to a more active usage of the UCC web site because a person who is an extrovert likes to spend time on activities with other people, is sensitive to new experiences and stimuli and thus actively responds to these. An extroverted person accepts new UCC activities as part of his/her social life, rather than getting away from this new UCC environment. This is represented by the term 'Foxonomy' where the users meet a variety of users from all over the world and contact new types of content created by these users. However, neuroticism creates the opposite situation to that created by extroversion. The representative symptoms of neuroticism are instability, stress, and tension. These dispositions are more closely related to stress caused by a new environment rather than this creatingcuriosity or pleasure. Thus, neurotic persons have an uneasy feeling and will eventually avoid the situation where their own or others' daily lives are frequently exposed to the open web environment, this eventually makes them have a negative attitude towards the web environment. When it comes to an individual's personality and how useful site is, the two personality factors of extroversion and neuroticism both have a positive relationship with the recognition of how useful the site and its content is. The positive, curious, and social dispositions of extroverted persons tend to make them consider the future usefulness and possibilities of a new type of information system, or website, based on their positive attitude, which has a significant influence on the recognition of how useful these UCC sites are. Neuroticism also favorably affects how useful a UCC website can be through a different mechanism from that of extroversion. As the neurotic persons tend to feel uneasy and have much doubt about a new type of information system, they actively explore its usefulness in order to relieve their uncomfortable feelings. In other words, neurotic persons seek out how useful a site can be in order to secure their own stable feelings. Meanwhile, extroverted persons explore how useful a site can be because of their positive attitude and curiosity. As a lot of MIS research has revealed that the recognition of how useful a site can be and how pleasurable it can be to use have been proven to have a significant effect on UCC activity. However, the relationship between these factors reveals different aspects based on the user's involvement in creation. This factor of creationgauges the interest of users in the creation of UCC contents. Involvement is a variable that shows the level of an individual's mental effort in creating UCC contents. When a user is highly involved in the creation process and makes an enormous effort to create UCC content (classed a part of a high-involvement group), their own pleasure and recognition of how useful the site is have a significantly higher effect on the future usage of the UCC contents, more significantly than the users who sit back and just retrieve the UCC content created by others. The cognitive and emotional response of those in the low-involvement group is unlikely to last long,even if they recognize the contents of a UCC website is pleasurable and useful to them. However, the high-involvement group tends to participate in the creation and the usage of UCC more favorably, connecting the experience with their own goals. In this respect, this research presents an answer to the question; why so many people are participating in the usage of UCC, the representative form of the Web 2.0 that has drastically involved more and more people in the creation of UCC, even if they cannot gain any monetary or social compensation. Neither information system nor a website can succeed unless it secures a certain level of user base. Moreover, it cannot be further developed when the reasons, or problems, for people's participation are not suitably explored, even if it has a certain user base. Thus, what is significant in this research is that it has studied users' respondent behavior based on an individual's innate personality, emotion, and cognitive interaction, unlike the existing research that has focused on 'compensation' to explain users' participation with the UCC website. There are also limitations in this research. Firstly, I divided an individual's personality into extroversion and neuroticism; however, there are many other personal factors such as neuro-psychiatricism, which also needs to be analyzed for its influence on UCC activities. Secondly, as a UCC website comes in many types such as multimedia, Wikis, and podcasting, these types need to be included as a sub-category of the UCC websites and their relationship with personality, emotion, cognition, and behavior also needs to be analyzed.

  • 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.

  • It is significant for developing the future for us to know our present age. In order to preserve our Korean costume as a fola clothes retaining our distinguished independent characterisitics and to help design the tomorrow of our Korean costume playing a role as a racial to develop the world clothing culture, a survey was conducted to investigate modern people's conscious-ness and wearing practumes of Korean costume by questionaire and interviewing methods. The results of the survey were analyzed as follows: (1) At present, Korean costumes were purchased as customtailored(64.0%) and as ready-made(17.8%) and most of them were not made at individual homes. The laundry and ironing of them were carried out at laundry shops(68.8%). Considering our present economic, social and cultural aspects, sowing, laundryand ironing will not be carried out at homes again in the future and ready made costumes seen to be produced in a large scale in the future. Garment makers and laundry shop operators should be trained how to make our Korean costumes retain our traditional beauty in the course of their production and laundry and the makers of ready-made costumes must make research how to efficiently produce ideal ready-made costumes by adopting the synchro system in their wrk odisivion. (2) The age group wearing Korean costumes most frequently was the aged people over 60 (their wearing rate; 45%-50%) and the group wearing them most frequently next io the aged people over 60, was housewives(their wearing rate; 15%-20%). Excludign aged people and housewives, other respondentsdid not wear Korean costumes very frequently. Men's wearing rate was lower their wearing rate was the younger their ages were and the less their monthly incomes were. Korean costumes were used for holiday and festival(60%), wedding and funeral ceremonies (52%), visiting and working(22%), casual wear(12.8%) and home wear(9.2%). The use of Korean costumes as casual and home wears, was lower than the use for holday, festival, visiting and working, Under our present circumstances in which our Korean people use both Western style clothes and Korean costumer, our Korean costume has lostits position as a basic and necessary requiement in Korean people's daily life and become a ceremonical and fancy costume. It is natural that the times and life change everything in our daily life. Our costume has to be made as good ceremonial and fancy clothes satisfying modern sensibility according to its new role. In order for us to get close with our clothes, a keen study must be carried out to cleat the color, material, style, function and harmony of the Korean costume matching the of the times. (3) The 47.8% of the respondents answered that they were proud of our Korean costume as our folk clothes, 47.6% replied that thought them just common and 1.1% responded that they were ashamed of it. Most of them were affirmative in feeling pride with our Korean costume. (4) Considering the functional aspect of Korean costumes, their strong points were symetric beauty, rhythmical beauty, unity feeling, harmonical beauty and detailed decorations. Their common shortcomings were lack of individuality and inadequateness for active life. The shortcomings of woman costumes were suppressing breast, making resperation difficult and in adequnteness in summer time. The main reason not to wear our Korean costumes, was due to the fact that they are incomvenient for active life. As a measure to eliminate such shortcomings, 1) the suspension system of skirt to remove the suppression of breast should be generally adopted. 2) they should be simplified in their structure to make them convenient for active life and adepuate in wearing them in hot weather in an extent to which the traditional beauty of the costume may not be lostand 3) a new technique must be explored for showing individuality by wearing method and new arrangment of colors and decorations. (5) The reasons desiring to wear Korean costumes were classifide as follows: A. Korean costumes are our traditional clothes(43.4%). B. Korean costumes are noble and beautiful(26.8%). C. They are accustomed to wear Korean costumes by habit(19.5%). D. Korean costumes are necessary for attending ceremoneis(9.5%). E. Miscellaneous reasons(0.8%). Classifying these reasons into age groups, the high age group over 40 wore them because they were easy to wear by habit and the low age group of 10-30 never thought that they were east to wear by habit. Considering that even those who were accustomed to wear Korean costumes showed a low wearing rate and that the young generation were accustomed to wear Western style clothes rather than Korean costumes, the wearing rate of Korean costumes will be reduced in the future if such trend continues. It is urgent for us to make our best efforts in order to enhance the interest of young generation in Korean costumes and not to make them lose the strong points of Korean costume in the future. (6) Conicering the plan of the respondents on what kind of clothes they were going to wear in the future, among the age group over 50, those who wanted to wear only Korean costumes were 24.8%(men) and 35.1%(women), those who wanted to wear 49.7%(men) and 47.4(women), those who wanted to wear chiefly Western style clothes were 20.7% (men) and 14.4%(women) and those who wanted to wear only Western style clothes, were 2.4% (men) and 2.1%(women). This shows that the general tendency to wear only or chiefly Korean costumes is more prevalent than that to wear only Western style. Among the age group under 50, the tendency to wear Western style clothes was conspicuous and most of the respondent answered that they would wear chiefly Western style clothes and Korean costumes occasionally. Only 5.4% of the respondent answered that they would wear only Western style clothes and this shows that meny respondents still wonted to wear Korean costumes. Those who wanted their descendants to wear what they desire, were 50.1%(men) and 68.8% (women) and those who wanted their descendants to wear Koran costumes occasionally, were 85.8%(men) and 86.3%(women). This shows that most of respondents wanted their descendants to wear Korean costumes. In order to realize, it is necessory for us to make ourdescendants recognize the preciousness of our traditional culture and modify our Korean costumes according to their taste so that they may like wearing them.

  • 이 연구는 근거이론 방법을 활용하여 중도장애인의 레질리언스 과정을 분석한 것이다. 이를 위해 갑작스러운 사고로 장애를 갖게 된 중도장애인 8명을 심층 인터뷰하였다. 연구 결과, 총 393개의 개념이 도출되었고, 이를 45개의 하위범주, 18개의 상위범주로 유목화할 수 있었다. 중도장애인 레질리언스 과정의 패러다임 모형에서 인과적 조건은 '장애에 대해 모름', '너무 아파 힘듦', 심리적 고통으로 '마음 안으로 숨어듦'인 것으로 나타났다. 맥락적 조건으로는 '집에만 있어 무기력해지고', 장애인정이 어려워 '스스로 장벽을 쌓으며', 장애에 대한 '사회적 장벽'으로 좌절을 경험하는 것으로 나타났다. 또한 장애유형, 장애정도, 성(gender), 장애획득시기, 중도장애 여부 등에 따라 레질리언스에 차이가 있음을 보고하였다. 이러한 인과적 조건과 맥락적 조건에도 불구하고 중도장애인이 레질리언스를 갖게 되는 중심현상은 '긍정의 힘에 탄력이 붙음'으로 확인되었다. 이러한 중심현상을 촉진 혹은 억제하는 중재조건으로는 외적으로 가족, 친구, 주변사람, 제도의 지원을 통해 '혼자가 아님을 깨닫고', 내적으로 종교의 힘과 모델링을 통하여 '변화의 의지와 삶의 목표를 가지고 내일을 준비하는' 것으로 나타났다. 작용/상호작용전략은 '노력을 배가하고', '직접 찾아보며', '능동적으로 실행하기'로 나타났으며 그 결과 중도장애인들은 장애와 사회에 대한 '관점이 달라지고', 삶의 '여유가 생기며', 매사에 '적극적으로 참여함'을 알 수 있었다. 중도장애인 레질리언스 과정의 핵심범주는 '긍정의 힘을 믿으며 주도적으로 나의 삶 선택하기'이었으며, 이는 장애인 레질리언스에서 선택과 자기결정을 통한 주도성의 확보가 매우 중요함을 보여주는 것이다. 과정분석에서는 '고통', '낯섬', '성찰', '일상' 단계로 확인되었으며, 이 단계들은 단선적이기보다는 역동적인 순환과정으로 나타났다. 이 과정에서 중도장애인의 레질리언스 유형은 존재성찰형, 진로개척형, 은근노력형, 적극실행형으로 구분되었다. 또한 개인, 가족 및 친구, 사회 및 제도 차원의 위험 및 보호요인에 관한 상황모형을 정리함으로써, 향후 실천적 개입을 위한 기초 자료를 제시하였다. 본 연구는 국내에서 처음으로 중도장애인의 레질리언스 과정을 근거이론 방법을 활용하여 심층적 이해를 구축하면서 그 과정 및 유형, 상황모형 등을 구체적으로 밝힘으로써 중도장애인 연구에 관한 이론구축 및 정책적, 임상적 개입에 그 함의가 클 것으로 기대한다.

  • 해수 중 용존 이산화탄소 농도 증가가 두토막눈썹참갯지렁이(Perinereis aibuhitensis)의 세포내 에너지 할당(CEA, cellular energy allocation)에 미치는 영향을 알아보고자 0.39(대조구=390 ppmv), 3.03 (=3,030 ppmv), 10.3 (=10,300 ppmv), 그리고 30.1 (=30,100 ppmv) mM의 이산화탄소 농도를 갖는 해수에 청충을 7일간 노출하여 세포 에너지와 세포 전자전달체계(ETS, electro transport system) 활성을 분석하였다. 실험생물의 지질, 당질, 그리고 단백질 함량과 ETS로부터 에너지 소비율을 계산하여 CEA를 산출한 결과 이산화탄소 농도가 증가함에 따라 CEA가 감소하였다. 지질의 경우 이산화탄소 농도가 증가 할수록 지질함량도 증가하였으며, 당질은 이산화탄소 농도가 3.03 mM인 실험구에서 가장 낮고 10.3 mM인 실험구에서 일부 증가하였으나 가장 높은 농도에서는 다시 감소하는 경향을 보였다. 단백질은 이산화탄소 농도가 3.03 mM인 실험구에서는 영향이 없었지만, 10.3 mM 이상의 농도에서부터 유의한 수준의 CEA 감소가 나타났다. 에너지 소비율은 이산화탄소 최고 농도에서만 유의한 증가 현상이 나타났지만, CEA는 대조구와 비교해 3.03 mM의 실험구부터 감소하였다. 이산화탄소는 해수중 pH를 낮추어 시험생물에 스트레스를 증가시키고, 세포내 에너지 할당변화에 영향을 미친 것으로 판단된다. 해산 갯지렁이를 이용한 CEA 평가결과는 대기 중 이산화탄소의 증가 또는 이산화탄소 저감을 위해 추진되고 있는 해양 지중저장사업 과정에서 누출된 이산화탄소의 해양생태계 위해성을 예측하는 자료로 이용될 수 있을 것으로 판단된다.

  • 본 연구에서는 태백산국립공원 주요 탐방로 입구에 설치된 탐방객 자동 계수기 데이터를 이용하여 탐방로별 일간 탐방객수에 영향을 미치는 요인을 분석하고, 이를 바탕으로 탐방로를 유형화하였다. 일일 탐방객수를 종속변수로 다중회귀분석 실시한 결과, 개천절이나 눈축제 등 행사는 모든 탐방로의 탐방객수에 영향을 미쳐, 태백산국립공원의 일일 탐방객수를 결정하는 가장 큰 요인인 것으로 분석되었다. 3일 이상 휴일이 연속되는 연휴와 일반 공휴일도 대부분의 탐방로의 일일 탐방객수에 영향을 미쳤다. 강수량은 비산행 목적의 탐방객이 많은 탐방로의 탐방객수에는 부(-)의 영향을 미쳤으나, 산행 목적의 탐방객이 많은 탐방로의 탐방객수에는 유의미한 영향을 미치지 않아, 산행 목적 탐방객들은 날씨가 궂더라도 산행을 강행하는 것으로 나타났다. 기온은 산행 목적의 탐방객이 많은 탐방로의 탐방객수에는 정(+)의 영향을 미쳤으나, 눈축제가 열리는 당골광장 인근의 탐방로의 탐방객수에는 부(-)의 영향을 미쳐, 눈축제의 영향권인지 여부가 탐방로 관리에 결정적 요인이었다. K-mean clustering을 이용하여 18개 탐방로를 유형 분류한 결과, 태백산국립공원의 탐방로는 눈축제에 영향을 받는 유형(유형 1)과, 가까운 거리에 볼거리가 많아 비산행 탐방객이 많은 유형(유형 2), 그리고 산행을 목적으로 온 탐방객들이 대부분인 유형(유형 3)의 3개 유형을 분류할 수 있었다. 탐방로 유형별 탐방객 행태와 불법 행위 유형이 다르므로, 유형별 특성에 맞춰 탐방로 관리방안을 마련하여야 할 것이다.
