해충의 저항성발달로 야기되는 문제를 해결하기 위한 정보를 제공함으로써 향후연구를 촉진시키고자 하였다. 농약사용이 지속되는 한 저항성 발달은 필연적이라는 생각으로, 저항성발달을 지연시키기 위해 재배자가 활용할 수 있는 약제성질에 근거를 둔 약종선택, 혼용, 교호, 모자이크 처리 등 약제살포법과, 천적과 양립할 수 있는 선택성 살충제와 저항성 천적의 이용을 중심으로 한 병해충 종합관리(IPM)에 대해 고찰하였다. 저항성관리에 약종의 성질을 이용할 경우 약종별로 작용점과 mode of action(작용방식)이 같거나 다를 수 있고, 2차 해충과 함께 살충제의 활성, 잔류기간, 약제 저항성 발달에 대한 취약성도 다르다. 약제는 섭식, locomotion(거동), 비행, 교미, 포식자 회피 등에도 영향을 미치므로 종합적으로 고려하여 역교차저항성을 나타내는 살충제의 사용이 바람직하다. 농약혼용은 실제 많이 이루어지고 있고 앞으로도 그러하겠지만, 진정한 의미에서 저항성 발달 지연을 위한 혼용, 교호, 모자이크 처리법은 대립유전자의 우성도, 교차저항성, 유입(immigration), fitness 불이익 등과 함께 살충제의 작용방식과 작용점들의 차이에서 구성약제가 매우 높은 비율로 충을 죽이는 부의 교차저항성을 가진 살충제들의 채택에 대하여 논의하였다. 저항성 관리에 약제혼용의 대표적인 사례 22가지와 교호처리 사례 27가지를 표로 제시하였다. 혼용처리의 잠재적 불이익은 생물적 방제의 와해, 이차해충의 저항성발달, 고도의 저항성 개체군 선발, 다양한 살충제에 대한 교차저항성 범위 확대를 내포하고 있다. 교호처리는 살포약량을 높이거나 낮추고, 다른 대사기구를 가진 살충제를 사용하는 것도 고려되었다. 모자이크 처리는 진딧물 같이 정주성 해충인 경우에 연관없는 살충제를 교호로 다른 구역에 처리하거나, 살충제 처리한 열(列)과 그렇지 않은 것을 혼합 배치하여 저항성 발달을 지연시키거나 피해를 감소시킬 수 있다. 해충의 저항성 진화 측면에서 볼 때, 기생자와 포식자의 저항성과 선택성은 농약처리를 요하는 세대 수를 감소시키고 농약으로부터 피난처의 상보적 역할을 수행할 수 있다. 작물별, 기주별, 기생자와 포식자에게 선택성을 보이는 약제를 별도의 표로 요약하여 제시하였다. 기생자의 생존력 향상을 위해 살충제의 선택성과 선택성에 영향을 주는 내 외적 요인에 대하여 검토하였다. 농약사용 하에서 기생자를 사용하기 위해 농약에 대해 저항성이거나 내성이 있는 기생자를 검정, 채집 혹은 선발하는 것을 논의하였다. 포식자에 대한 선택독성에 영향을 미치는 요인들로 농약의 선택성, 선택성의 포장적용과 그에 미치는 요인, 포식자와 기주의 균형, 선택성을 도외시한 방제법의 문제점, 천적과 농약의 양립성 등에 대하여 논의하였다.

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.

Personalized services directly and indirectly acquire personal data, in part, to provide customers with higher-value services that are specifically context-relevant (such as place and time). Information technologies continue to mature and develop, providing greatly improved performance. Sensory networks and intelligent software can now obtain context data, and that is the cornerstone for providing personalized, context-specific services. Yet, the danger of overflowing personal information is increasing because the data retrieved by the sensors usually contains privacy information. Various technical characteristics of context-aware applications have more troubling implications for information privacy. In parallel with increasing use of context for service personalization, information privacy concerns have also increased such as an unrestricted availability of context information. Those privacy concerns are consistently regarded as a critical issue facing context-aware personalized service success. The entire field of information privacy is growing as an important area of research, with many new definitions and terminologies, because of a need for a better understanding of information privacy concepts. Especially, it requires that the factors of information privacy should be revised according to the characteristics of new technologies. However, previous information privacy factors of context-aware applications have at least two shortcomings. First, there has been little overview of the technology characteristics of context-aware computing. Existing studies have only focused on a small subset of the technical characteristics of context-aware computing. Therefore, there has not been a mutually exclusive set of factors that uniquely and completely describe information privacy on context-aware applications. Second, user survey has been widely used to identify factors of information privacy in most studies despite the limitation of users' knowledge and experiences about context-aware computing technology. To date, since context-aware services have not been widely deployed on a commercial scale yet, only very few people have prior experiences with context-aware personalized services. It is difficult to build users' knowledge about context-aware technology even by increasing their understanding in various ways: scenarios, pictures, flash animation, etc. Nevertheless, conducting a survey, assuming that the participants have sufficient experience or understanding about the technologies shown in the survey, may not be absolutely valid. Moreover, some surveys are based solely on simplifying and hence unrealistic assumptions (e.g., they only consider location information as a context data). A better understanding of information privacy concern in context-aware personalized services is highly needed. Hence, the purpose of this paper is to identify a generic set of factors for elemental information privacy concern in context-aware personalized services and to develop a rank-order list of information privacy concern factors. We consider overall technology characteristics to establish a mutually exclusive set of factors. A Delphi survey, a rigorous data collection method, was deployed to obtain a reliable opinion from the experts and to produce a rank-order list. It, therefore, lends itself well to obtaining a set of universal factors of information privacy concern and its priority. An international panel of researchers and practitioners who have the expertise in privacy and context-aware system fields were involved in our research. Delphi rounds formatting will faithfully follow the procedure for the Delphi study proposed by Okoli and Pawlowski. This will involve three general rounds: (1) brainstorming for important factors; (2) narrowing down the original list to the most important ones; and (3) ranking the list of important factors. For this round only, experts were treated as individuals, not panels. Adapted from Okoli and Pawlowski, we outlined the process of administrating the study. We performed three rounds. In the first and second rounds of the Delphi questionnaire, we gathered a set of exclusive factors for information privacy concern in context-aware personalized services. The respondents were asked to provide at least five main factors for the most appropriate understanding of the information privacy concern in the first round. To do so, some of the main factors found in the literature were presented to the participants. The second round of the questionnaire discussed the main factor provided in the first round, fleshed out with relevant sub-factors. Respondents were then requested to evaluate each sub factor's suitability against the corresponding main factors to determine the final sub-factors from the candidate factors. The sub-factors were found from the literature survey. Final factors selected by over 50% of experts. In the third round, a list of factors with corresponding questions was provided, and the respondents were requested to assess the importance of each main factor and its corresponding sub factors. Finally, we calculated the mean rank of each item to make a final result. While analyzing the data, we focused on group consensus rather than individual insistence. To do so, a concordance analysis, which measures the consistency of the experts' responses over successive rounds of the Delphi, was adopted during the survey process. As a result, experts reported that context data collection and high identifiable level of identical data are the most important factor in the main factors and sub factors, respectively. Additional important sub-factors included diverse types of context data collected, tracking and recording functionalities, and embedded and disappeared sensor devices. The average score of each factor is very useful for future context-aware personalized service development in the view of the information privacy. The final factors have the following differences comparing to those proposed in other studies. First, the concern factors differ from existing studies, which are based on privacy issues that may occur during the lifecycle of acquired user information. However, our study helped to clarify these sometimes vague issues by determining which privacy concern issues are viable based on specific technical characteristics in context-aware personalized services. Since a context-aware service differs in its technical characteristics compared to other services, we selected specific characteristics that had a higher potential to increase user's privacy concerns. Secondly, this study considered privacy issues in terms of service delivery and display that were almost overlooked in existing studies by introducing IPOS as the factor division. Lastly, in each factor, it correlated the level of importance with professionals' opinions as to what extent users have privacy concerns. The reason that it did not select the traditional method questionnaire at that time is that context-aware personalized service considered the absolute lack in understanding and experience of users with new technology. For understanding users' privacy concerns, professionals in the Delphi questionnaire process selected context data collection, tracking and recording, and sensory network as the most important factors among technological characteristics of context-aware personalized services. In the creation of a context-aware personalized services, this study demonstrates the importance and relevance of determining an optimal methodology, and which technologies and in what sequence are needed, to acquire what types of users' context information. Most studies focus on which services and systems should be provided and developed by utilizing context information on the supposition, along with the development of context-aware technology. However, the results in this study show that, in terms of users' privacy, it is necessary to pay greater attention to the activities that acquire context information. To inspect the results in the evaluation of sub factor, additional studies would be necessary for approaches on reducing users' privacy concerns toward technological characteristics such as highly identifiable level of identical data, diverse types of context data collected, tracking and recording functionality, embedded and disappearing sensor devices. The factor ranked the next highest level of importance after input is a context-aware service delivery that is related to output. The results show that delivery and display showing services to users in a context-aware personalized services toward the anywhere-anytime-any device concept have been regarded as even more important than in previous computing environment. Considering the concern factors to develop context aware personalized services will help to increase service success rate and hopefully user acceptance for those services. Our future work will be to adopt these factors for qualifying context aware service development projects such as u-city development projects in terms of service quality and hence user acceptance.

The work-related diseases due to continuous overwork are mainly cerebro- and cardio-vascular ones, which is commonly called 'Karoshi', death from overwork. Many factors are capable for Karoshi : occupational stress in relation to technological renovation and industrial rationalization, competitive social structure, and accumulated fatigue accured to long time or irregular working. And its occurence is on the rise. The World Labor Report 1993 released by ILO, pointed out the diseases related to overwork and stress as one of the most important occupational health problem. In Korea, social awareness of Karoshi is at an infant stage, and reliable statistics for its occurence are not compiled in a convenient manner. Despite the rising Karoshi, there are no reliable clauses in workmen's compensation enough to settle down the disputes. Therefore, it is not uncommon that the Labour Ministry and Civil Court find difficulties in reaching an agreement. This study was intended to provide proper compensation and prevention program for workers by suggesting reasonable compensation clauses for the death from overwork. This study consists of two comparative reviews on the compensaton clauses for the death from overwork. One is to review legal standards of Karoshi among three countries, such as Korea, Japan and Taiwan. The other is to investigate the cases of Karoshi in Korea, 121 cases identified at the Labor Welfare Corperation and the Labour Ministrial process of examination and reexamination, and 73 leading cases at the High Court of Justice. The main findings of the study are as follows : 1. Comparisons of comperative review on compensation clauses for the death from overwork among three countries. 1) All of three countries have the same kinds of disease for compensation, which were cerebro-and cardiao-vascular diseases, while for cardiac disease group, Korea has the smaller number of diseases for compensation than Japan. 2) As for the definition of overwork, the three countries share equally that overload for one week prior to collapse is considered as an important factor, but accumulated chronic fatigue is disregarded. 3) As the basis of overwork, in Japan, there is a tendency to move from the conditions of an ordinary healthy adult to those of the individual concerned in Japan, whereas there is no such concern yet in Korea. 4) All the three countries use a common standard of medical judgement in demonstrating causal relationship between a job and a disease. However, Korea is progressive in the sense that in the case of CVA at worksite, the worker himself has no obligation to prove the cause. 2. The results of a comparative review on excutive decisions by Labor Ministry and judicial decisions by the Court in Korea : A judicial decision is based on the legalistic probability, but a excutive decision is not. Therefore, excutive decisions have such restrictions that : 1) TIA (transitory ischemic cerebral attack) and myocarditis are excluded from compensation, and there is little consistency of decision in the case of cause-unknown death. 2) There is a tendency not to compensate for the death from overwork since the work terms such as repeated long-time working, shift work or night-shift work are not considered as overloading. 3) There is a tendency to regard the conditions of a ordinary healthy adult rather than those of the individual concerned(age, existing diseases, health state, etc.) as the comparative basis of overload. 4) There remains a tendency not to compensate for the death from overwork in the case of collapse occuring out of workplace, on the ground of 'on the course of working' and 'in the cause of accident'. Through the study, the fact manifests itself that Korea's compensation clauses for work-related diseases due to overwork are very restrictive. So, it is necessary to extend the Labor Ministry's clauses of compensation for the death from overwork following to the recent changes of other countries and internal judicial decisions. This is very important in the perspective of occupational health that aims at health promotion of workers including prevention of the Karoshi.

최근 '창조 경제', '문화 융성' 등이 도시 및 지역 성장의 새로운 방법론으로 부상하면서 문화 산업에 대한 보다 다양한 연구가 요구되고 있다(Kim, 2013). 또한 지역의 창조역량을 강화하고 자생적이며 내발적인 지역문화 발전을 위한 정책마련의 중요성이 증대되고 있다(Ryu et al., 2012). 이러한 흐름에서 자생적으로 문화산업에 종사하는 창조계급들이 집적하여 나타나며, 새로운 문화경관을 형성하고 있는 경리단길을 고찰하여 그 집적요인 및 문화경관의 변화양상을 밝히고자 한다. 본 연구는 최근 급격한 변화과정에 있는 서울 용산구 이태원2동 회나무로(경리단길)를 연구함에 있어, 인근 지역인 이태원1동의 상업시설 포화상태로 인한 상업 공간의 확장 때문이라는 기존의 인식과는 달리 경리단길에 유입되고 있는 '창조계급'이 지역의 변화를 직 간접적으로 유도하며, 지역의 문화 및 경관을 변화시키고 있다는 관점에서 논의하고자 하였다. 본 연구의 목적은 다음과 같다. 첫째, 1910년대 일본군 기지 조성에 따른 영향으로 변화하기 시작하여 현재에 이르는 과정을 문화경관형성 과정으로 보고, 대상지 경관 변화의 역사적 맥락을 연구하고자 하였다. 둘째, 경리단길의 변화를 주도하는 주체로서 창조계급이 경리단길에 유입된 과정을 고찰하고, 어떠한 요인에서 경리단길에 유입되고 있는지를 밝히고자 하였다. 셋째, 이들의 활동이 지역의 문화 및 경관을 변화시키고 있다는 가설 하에 이들의 활동을 분석하여 경리단길의 독특한 문화경관형성 양상을 고찰하고자 하였다. 연구의 방법으로는 창조계급의 4집단(디자이너 및 건축가 집단, 독립 갤러리 및 카페(음식점)+갤러리 운영자 집단, 예술가 집단, 에스닉푸드 음식점 운영자 집단)들이 경리단길에 유입되고 있는 과정을 생생하게 고찰하기 위하여 심층인터뷰 연구를 진행하였다. 또한 이를 객관적이며 구조적으로 분석하기 위해 위해 Ratner(2002)가 제시한 인터뷰 대화내용 분석의 4단계를 활용하였다. 연구의 결과 창의적 문화산업 종사자가 경리단길에 유입되는 요인으로는 '저렴한 임대료에 비해 이슈화되고 있는 지역', '자연과 공존하는 도시', '도시의 혼잡스러움과는 격리된 듯한 호젓한 분위기', '자신이 좋아하는 개성 있는 소재를 시험하고 공유할 수 있는 장소', '지인과의 네트워크를 통해 활동의 시너지효과를 기대할 수 있는 장소'라는 5가지의 요인이 도출되었다. 또한 이들의 활동으로 형성되고 있는 문화경관의 특징으로는 창의성 증진을 위한 소통의 공간, 일시적이며, 유연한 공간의 활용, 자신의 정체성 및 취향의 표현, 구분짓기, 기존 시설의 적극적 활용이라는 5가지의 특징이 도출되었다. 이와 같이 본 연구는 경리단길의 변화과정을 주도하고 있는 주체인 '창조계급'을 드러냄으로써 경리단길 문화경관이 형성되고 있는 양상을 밝혀냈으며, 문화산업에 대한 보다 다양한 고찰이 요구되는 시점에서 자생적으로 문화산업에 종사하는 창조계급이 집적하여 나타나는 실제의 대상지를 연구함으로써 실증적인 유입요인 및 지역의 변화양상을 밝혀내었다.

본 연구는 숙면 유도 호르몬으로 알려진 멜라토닌의 원유 및 유제품 내 함량을 방사면역측정법으로 분석하였으며, 그 결과는 다음과 같다. 1. 착유 시간에 따른 멜라토닌 함량은 새벽 4시에 착유한 원유 샘플의 멜라토닌 함량이 평균 $6.90{\pm}3.55pg/mL$로 나타났으며, 저녁 7시 및 낮 12시 착유 원유 샘플은 각각 $2.01{\pm}1.47pg/mL$와 $0.16{\pm}0.04pg/mL$로 나타나 새벽 착유 원유 내 멜라토닌 함량이 유의적으로 높은 결과를 나타내었으며, 이는 로봇 착유기를 사용하는 농가에서도 심야 및 새벽 착유 원유에서 멜라토닌 함량이 가장 높게 나타나 2개 목장 모두 비슷한 결과를 나타내었다. 2. 일반 우유 제품과 나이트 밀크 제품 간 멜라토닌 함량비교 시, 나이트 밀크의 멜라토닌 함량이 약 5배 정도 높은 결과를 보였다. 3. 일반 우유를 대상으로 원유, 균질 및 살균 등의 공정이 멜라토닌 함량에 영향을 미치지 않는 것으로 나타났으나, 그 수준은 매우 낮은 농도로 존재하였다.

인터넷을 통한 개방적 협업의 가치가 사회 경제적으로 증가하고 있는 가운데, 오픈소스 소프트웨어 개발 프로젝트의 성공적인 운영의 중요성 또한 증가하였다. 기존의 연구들이 프로젝트 성과에 영향을 미치는 다양한 요인들을 검증하였으나 프로젝트 운영자가 프로젝트 성과에 어떤 영향을 미치는지에 대한 연구는 한정적이다. 따라서 본 연구는 운영자의 특성을 개인의 특성과 운영 방식의 특성으로 나누어 인상형성 및 사회적 자본 이론을 중심으로 그 영향을 검증하였다. 이를 위하여 대표적인 오픈소스 소프트웨어 개발 플랫폼인 깃허브(Github)에서 611개의 리퍼지토리(Repository)와 리퍼지토리 운영자의 데이터를 수집하였으며, 사회 연결망분석을 통해 각 리퍼지토리의 지식공유 네트워크를 구축하였다. 위계적 회귀분석을 통해 프로젝트 성과에 영향을 미치는 명시적 리더의 특성을 분석한 결과, 운영자가 개인의 정보를 많이 공개하여 신뢰성을 확보하고자 노력하거나, 적극적으로 팔로잉을 하여 외부 개발자에 대한 관심이 높거나, 지식공유 네트워크에서 중심적인 역할을 할 경우 성과에 긍정적인 영향을 주는 것으로 나타났다. 반면, 코드의 수용비율이 높거나, 깃허브 내에서 전문가로 인지되어 있을 경우 오히려 성과가 낮은 것으로 나타났다. 본 연구는 향후 오픈소스 소프트웨어뿐만 아니라 다양한 형태의 개방적 협업의 성공적 운영을 위한 운영자 가이드라인으로 활용될 수 있을 것으로 기대된다.

Changes in a drug's availability from prescription only to over-the-counter (OTC) status is of concern to physicians from both public health and individual patient perspectives. Government has generally been supportive of changes in medications from prescription(Rx) to over-the-counter (OTC) status in Korea, however, recognizing that there are both benefits and risks to any health care intervention, health care professionals are conservative in implementing changes to either the process or structure of health care. Changes in status of a drug from Rx to OTC can represent a change in both structure and process. Cost and convenience seem to be major factors in determining whether, given the choice, patients purchase a medicine over the counter or obtain it on prescription. With current arrangements, exemption from prescription charges provides an incentive to continue to obtain products on NHS prescription even when they are available over the counter. There is therefore no simple relation between the availability of over the counter medicines and the level of prescribing of deregulated products. The appropriate use of over the counter medicines-particularly those that have only recently been deregulated-places a burden of care on community pharmacists and calls for closer working relationships with general practitioners. In particular, systems for referral and for recording details of both prescribed and over the counter medicines need to be developed, and a direct route needs to be established for community pharmacists to report adverse drug reactions to over the counter products. Reclassification of prescription medicines-by making them available through pharmacies without a prescription-provides the opportunity for consumers to purchase a wider range of medicinal products without making a demand on NHS resources. There is, however, no simple relation between availability of over the counter medicines and demand for NHS prescriptions. In the late 1980s the UK government fuelled the over the counter market by making it easier to reclassify certain medicines from prescription only status to allow over the counter sale in pharmacies. To explore the influence of deregulation of medicines on NHS prescribing, this article presents analyses of consumer behaviour in using medicines and prescribers' attitudes to over the counter medication and collates findings from research. Policy makers should be aware that patients' expectations in relation to OTC medicines may be in conflict with evidence-based practice.
