Rapid socio-cultural and economic changes in the country has brought with it changes in the society's value system. For a traditional society that is increasingly being exposed to modernization but where sex norms are still very restrictive, the adolescent sexual mores takes on added significance. Adolescents are caught between two opposing forces, the changing environment that allows for freer and liberal mores and the traditional society that cannot keep pace with the changing environment and therefore demands resistance to changes. This paper focuses on problems of adolescent sexuality in this country and considers the countermeasures for the existing problems. Amongst the problems are: (a) increasingly younger age of the adolescents who start sexual intercourse (b) non-use of contraception, (c) unwanted pregnancies, (d) increase in the number of induced abortion and (e) increase in the number of unwanted children and unmarried mothers. The Korean adolescent's sexual behavior seems to follow that of the developed countries. In other words, many western modes of life and sexual values seem to bave been copied in Korea and yet Korean adolescents lack in their knowledge of sex related matters such as reproductive physiology and contraception. Among middle and high school students, female students are reported to have less knowledge on sex than male students according to a 1988 survey by KIPH. Even among the unmarried famale factory workers, only 42.5 percent replied they know of the condom, and 25.1 percent and 23.1 percent said they had knowledge of spermicide and menstrual regulation respectively. However, 14.9 percent and 13.9 percent reported that they had a knowledge of the loop and female sterilization respectively according to the 1984 study by KIPH. Among the middle school students 0.8 percent said they had experience in sexual intercourse, while 7.3 percent of the high school students reported having had sexual intercourse. The sexual intercourse experience rate among the unmarried female factory workers is 37.8 percent. Among those female factory workers with sexual experience, 46.7 percent had more than one sex partners. Only 39.1 percent of male students and 18.9 percent of female students among those with sexual intercourse experience have used contraceptives. mostly condoms and oral pills 45.1 percent of female factory workers with sexual intercourse experience used contraceptives such as pills, condoms and rhythm methods. The pregnancy experience rate among the female factory workers who had experience in sexual intercourse is 29.5 percent, which is 11.1 percent among the total respondents. Out of the 102 pregnant female workers, 98 workers(96.1 percent) terminated their pregnancy by induced abortion and 2 workders(2 percent) in natural abortion, while 1 worker(1 percent) was in pregnancy and another 1 worker had normal birth that was subsequently sent to orphanage. In order to cope with the problem of adolescent sexuality, a drastic and strong policy measures should be taken by the government. The most effective countermeasure to the adolescent sexual problems appears to the education. The sex and population education in the school is very much in need. In addition, sex education program through mass media and at the job sit-should be promoted for a healthy development of adolescents' sexual behavior. Also, the existing national family planning program, which has focused on the married couples, should be extended to the unmarried people in its scope and contents of the program.

In Korea, groundwater is main water source in livestock farms. Most dairy and cattle farms have constructed their own wells for human drinking and livestock farming. However, these private residential wells have not been controlled by government and also there was scant study about livestock drinking water quality. Therefore this study was to monitor of the livestock farms' groundwater quality in Korea. Water samples were collected at 123 dairy and cattle farms and were analysed forty six substances with quality standard for drinking water approved by the Minister of Environment. Seventy eight (63.4%) of 123 samples failed to drinking water stand a test. The most frequent contaminants were nitrate-nitrogen and microbial. 22.8% (n=28) of samples showed nitrate-N concentration of higher than 10 mg/L meant that can't be used drinking water for human and the Nitrate-N concentration analysed in the range of 0.2 to 61.2 mg/L. All of 78 failed to drinking samples had microbial problems, especially 5.7% (n=7) of samples indicated water could be contaminated by feces. Other contaminants detected were zinc and evaporation residue. Especially detected zinc concentration (32 mg/L) was about ten times higher than standard of zinc (3 mg/L). Regression analysis indicated that groundwater pH did not influence to nitrate-N concentration but the hardness and chloride could affect to nitrate-N concentration in the groundwater. Most livestock farms were adjacent to crop farmland in Korea. This could cause contamination of groundwater with nitrate-N and pesticide that could accumulate livestock product. Moreover Heavy metal such as zinc and copper could be released from a corrosive plated water pipe in livestock farm. Put together, Korea livestock system is indoor, not pasture-based, hence livestock could be exposed to potential contaminated water consistently. Therefore on the basis of these data, appropriate livestock drinking water quality standards should be prepared to keep livestock healthy and their product safe. Further, livestock drinking water quality should be monitored continuously in suitable livestock drinking water standards.

Background: It is projected that low and middle-income countries will bear a major burden of tobacco related morbidity and mortality, yet, only limited information is available on the determinants of smoking initiation among youth in Africa. This study aimed to assess the determinants of smoking initiation and susceptibility to future smoking among a population of high school school students in Lagos, Nigeria. Materials and Methods: Baseline data from an intervention study designed to assess the effect of an anti-smoking awareness program on the knowledge, attitudes and practices of adolescents was analyzed. The survey was carried out in six randomly selected public and private secondary schools in local government areas in Lagos state, Nigeria. A total of 973 students completed self-administered questionnaires on smoking initiation, health related knowledge and attitudes towards smoking, susceptibility to future smoking and other factors associated with smoking. Results: Of the respondents, 9.7% had initiated smoking tobacco products with the predominant form being cigarettes (7.3%). Males (OR: 2.77, 95%CI: 1.65-4.66) and those with more pro-smoking attitudes (OR: 1.44, 95%CI: 1.34-1.54) were more likely to have initiated smoking. Those with parents and friends who are smokers were 3.47 (95%CI: 1.50-8.05) and 2.26 (95%CI: 1.27-4.01) times more likely to have initiated smoking. Non-smoking students, in privately owned schools (OR: 5.08), with friends who smoke (5.09), with lower knowledge (OR: 0.87) and more pro-smoking attitudes (OR 1.13) were more susceptible to future smoking. In addition, respondents who had been sent to purchase cigarettes by an older adult (OR: 3.68) were also more susceptible to future smoking. Conclusions: Being male and having parents who smoke are predictors of smoking initiation among these students. Consistent with findings in other countries, peers not only influence smoking initiation but also influence smoking susceptibility among youth in this African setting. Prevention programs designed to reduce tobacco use among in-school youth should take these factors into consideration. In line with the recommendations of article 16 of the WHO FCTC, efforts to enforce the ban on the sales of cigarettes to minors should be also emphasised.

Purpose: Ths study aims to examine characteristics of patients using emergency room after execution of five-day workweek system by government and provide basic materials for operation of efficient emergency room. Methods: Data were collected tbrough medical records of patients visiting emergency room from July of 2004 to October of 2006 and they were analyzed with SPSSlPC 10.0. Conclusion : 1. The number of patients visiting emergency room was average 16.7 persons a day in 2004, 17.5 in 2005 and 18.6 in 2006 and it was found that it was increasing every year since the execution of five-day workweek system 2. Gender distribution of subjects using emergency room was higher in male than in female every year. 3. Means of transport to emergency room were mostly private car and others(public transport or on foot), but use of ambulance was increasing. 4. Residential areas of subjects were mostly 'Myeon area' in 2004~2005, but it was changed to residents at 'Eup area' in 2006. 5. Distribution of patients by medical departments was highest in internal medicine and surgery in 2004~2006 and rate of visiting pediatrics was increasing every year. 6. Time to stay at emergency room was most at 'below 30 min'. in 2004~2006, but cases of stay for 'more than 2 hours' were increasing every year. 7. On presence or absence of trauma in patients visiting emergency room, rate of visit to emergency room with 'no trauma' was higher and this result was increasing every year. 8. As a result of classifying severity of patients visiting emergency room, use rate of emergency room by 'non-emergency' patients was over 90% in 2004~2006 and such a phenomenon was deepened in 2006 compared to that in 2004. 9. Measures after emergency care of patients were most in case of 'discharge' in 2004~2006, but cases of admission to hospital after emergency care were increased every year. 10. According to use of emergency room by a day of the week, use on Sunday was most frequent in 2004~2006, but use on Friday the day before holiday was increasing. 11. According to distribution by age, use by those between '40~49' was most in 2004~2005, but use by those 'below 10' was most in 2006. 12. According to time to visit emergency room, using emergency room at "15:31~23:30 was most in 2004~2006, cases of visiting emergency room at day working hour were decreased every year and those at evening and night working hours were increased. Conclusion: In sum, it was found that characteristics of patients visiting emergency room and their actual status were changed after the execution of five-day workweek system and efforts to rearrange emergency medical system are required.

Current TMDL based on the 'Polluter Pays Principle' in Republic of Korea is individually operated by each local government for the designed allocated pollution load of unit watershed and unit district. However, unlike the motion of the air contaminants, the polluted contaminants in a river move from upstream to downstream, and a river can affect to districts more than two. In addition, a decision making on the construction of a sewage treatment facilities follows the concept of 'economy of scale'. These reasons support the collaboration among local governments in order to reduce the costs in improving water quality. This study suggested a method to reduce water quality management cost by redistributing reduction load considering cost-effectiveness for an entire watershed. The assessment on the suggested method is conducted in Youngsan river watershed. Without variation in total load, reduction load assigned for unit watershed and unit district is retributed in the region where pollutant source is concentrated, and then water quality and cost reduction improved from the redistribution of reduction load is analyzed. The results show that the cost saved by the suggested method is KRW 124 billion for scenario-1 and 172 billion for scenario-2 considering total cost of KRW 788 billion for the existing plan. We expect that the suggested method is a good example to reduce water quality management cost in local governments for TMDL.

In order to assess policies for training of radiological technologists and public health, this study was conducted from the mid July to the end of August 2003 to the subjects of 890 radiological technologists who work at 44 general hospitals in 16 cities and provinces of the country. For this purpose, an analysis of variance was performed by regions divided in Capital city, metropolitan areas and small- and medium-sized cities as well as by length of service. The outcomes look as follows : 1. From the analysis of replies to questions about the government health policy for radiological technologists, high scores were given to the items: "the Law of Medical Engineers should be revised from the pattern of supervision to assignment" and "the medical institutions should be legally obliged to secure certain number of radiological technologists". 2. From the analysis of variance by regions and groups, there was difference by regions in the items: "demand and supply of radiological technologists should be controlled" and "the license number of radiological technologists should be indicated in the medical insurance bill"(p<0.000). 3. From the analysis of variance as to training of radiological technologists, a significant difference was found by length of service in the items: "it is necessary to open a 4-year department of radiology and to revise curriculum" and "the legal system to indicate license number of radiological technologists in the medical insurance bill should be introduced". 4. The analysis of variance by length of service revealed that those who have served for more than 20 years favored "it is necessary to open a 4-year department of radiology and to revise curriculum" higher than those who have served for less than 5 years, showing a tendency the longer they work, the stronger they feel necessity".

Migrant Worker are rapidly increasing in Korea since 1990. They are nowadays main sources of laborer groups engaging in medium-sized factories. The purpose of this study is to provide the basic information to establish proper oral health policy. Dental caries and periodontal disese are the most common disease that occur in the mouth. Periodontal disease is the most common disease in humans and the biggest reason for the loss of the teeth in the adult population. The CPITIN has been developed jontly by the international Dental Federation and the World Health Organization. CPITN is now an established index of level, of periodontal condition in populations for which specific intervention might be considered. This study was conducted to obtain the information regarding to CPITN of migrant workers located in Daegu, Questionaire survey was carried out for 289 workers from July 9 to August 8, 2006. Total survey was 289, 224 males and 65 females. The result was as follows: First, The number of nationality was 14. The first majority was China as 31.8% Among 14 nationalities were Cambodia 18.0%, Vietnam 12.8%, Sri Lanka 12.1%, Indonesia 7.3%, Nepal 4.2%, the other 13.8%, those who are aged from 20 to 29 were 43.9%, and salary from 1,000,000 won to 1,490,000 won 51.2%.(as for their residence, those who resided) over 3 years were 42.6% and not insured reached 68.5%. Second, more than 93.4% of the subjects need periodontal treatment, only 4.9% of non-smoker was health periodontal states, four times frequency of tooth brushing per a day was 16.7%. Third, 28.7% of migrant workers had experienced visit of dental clinic, and 22.9% had received treatment of decayed tooth. Fourth, It is difficult for them 65.1% of them to visit dental clinic in korea, the First was a communication problem and the second was time. Fifth, Most of them didn't have a oral health education but 85.1% of them said that they wish they attend oral health education. We conclude that the situation of migrant workers was very bad considering their working conditions, circumstances, and health condition. According to this study, more than 93.4% of the people need periodontal treatment. Besides they didn't have accurate knowledge about prevention of periodontal disease. Therefor our considering these facts, the policy of dental health by government should be established for migrant workers.

In December 2015, 195 nations agreed to cut green house gas emissions in the Paris Climate Convention, and all over the world showed their willingness to participate in greenhouse gas mitigation. Accordingly, various technologies related to greenhouse gas reduction are being considered, among which carbon dioxide capture, storage, utilization (CCUS) technologies are attracting attention as an unique technology capable of directly removing greenhouse gases. However, CCUS technologies are still costly and have low efficiency. It is still more important to analyze the level of CCUS technology before commercialization and to understand trends and to predict future direction of technology. Therefore, this study analyzes the patent trends of CCUS technology and derives implications for future directions. As a result of country analysis, the United States had the highest number of applications, and sectoral analysis shows that 64% of total patents are from capture sector. Companies such as Alstom technology, Toshiba Corp, and Mitsubishi Heavy are focusing on capturing carbon dioxide. In Korea, government research institutes have focused on storage and utilization technologies. In addition, since the late 2000s, patent applications have increased rapidly, and many countries have been interested in the development of the technology and have made efforts to reduce greenhouse gas.

1997년과 1998년 4월 1일자의 M&A제한규정이었던 증권거래법 제200조의 철폐와 적대적 M&A의 전면허용 그리고 외국자본의 투자제한의 간소화 등 규제완화조치와, 향후 외국인에 대해서 100%까지 주식을 매입할 수 있는 적대적 M&A가 허용될 것으로 보여 우리나라에서도 M&A활동이 보다 본격화 될 것으로 전망되고 있다. 우리나라에서는 1980년대부터 M&A에 대한 관심과 연구가 시작되면서 지금까지 기업합병ㆍ인수의 동기와 효과에 대해서 많은 연구가 이루어져 왔다. 지금까지의 연구내용은 대부분 기업의 M&A동기는 시너지효과를 얻기 위함이며, 또한 공시정보가 합병공시일 전후동안에 주가수익율에 반영되어 합병 당사기업의 주주의 부에 영향을 미치는지의 주가변화 유무에 국한된 것이었다. 또한 1985년부터 1991년 초 사이에 이루어졌던 연구는 당시 국내 M&A 환경이 매우 열악하고 극히 제한된 비정상적인 자본시장 상황 하에서 이루어진 사례에 의한 연구이었기 때문에 연구결과의 문제점과 한계성이 있었고, 실효성 측면에서도 다소 미흡하였다고 할 수 있다. 우리나라 M&A의 성장발전과정을 크게 2단계로 분류한다면, 제1단계는 1975년부터 시작하여 1990년까지로써 이 기간동안의 M&A환경은 그 여건조성과 성숙준비단계였으며, 제2단계인 1990년 초부터 비로소 선진국형 시장경제원리에 근거한 보다 경쟁적이고 자율적인 M&A 시장구조가 형성되면서 활성화 단계로 진입하였다고 볼 수 있을 것이다. 본 연구의 주된 목적은 1990년부터 1996년 사이에 이루어진 상장기업의 M&A 사례를 표본으로 하여 한국에서의 기업합병과 기업인수(주식취득)가 기업가치에 미치는 영향을 구명하는데 있다. 이를 위하여 먼저, M&A 당사기업의 합병성과 발생과 차이 유무를 주가수익율을 측정하여 실증분석하고 다음으로 M&A에 따른 시너지의 잠재적 원천이 어디에 있는지 재무성과분석을 통해서 이를 실증하는데 목적이 있다.PA-designated retailers ("sellers") must accept end-of-life items returned to them by the consumers. At the local level, Taipei City implements a pay-as-you-throw program, whereby citizens pay waste collection and treatment fees through the purchase of special trash bags approved by the Taipei City Government. However. recyclables that are separated by citizens are collected free-of-charge by the City. Taichung City and Kaohsiung City, on the other hand, enforce mandatory sorting schemes, whereby citizens face penalties if they don't separate recyclables from the trash before pick-up. These programs have resulted in a significant reduction in municipal waste. Per capita waste collected per day has dropped from 1.143 kg in 1997 to 0.978 kg in 2000. Targeting a 10% recycling rate for municipal waste in 2001. EPA plans to research and develop new recycling techniques, expand the scope of producer responsibilities, and strengthen existing mu

After global financial crisis, policy makers in major countries tried to find a new bank recovery and resolution policy. The new policy intends to normalize the market not by bail-out approach in which public funds should be provided bankrupt banks, but by market discipline approach in which unsecured creditors take part in liquidation process. Bail-in system is a new and dominant financial policy after crisis period in resolution regimes led by the government administration. This study tries to analyze the relationship between bail-in system and pro-cyclicality. Empirical analysis has been done by taking the basis of the 8 year data from 2008 to 2015, which is selected from financial statistics information system of Korea Financial Supervisory Service. Accounting and financial data are collected from the dataguide 5.0 between 2008 and 2015. Through the analysis, the effect of bail-out system and bail-in system on pro-cyclicality of total loans did not show the statistically significant relationship. However the effect of bail-out system on pro-cyclicality of SME loans showed the statistically significant relationship, meanwhile the effect of bail-in system on pro-cyclicality of SME loans did not show the statistically significant relationship. In conclusion, bail-in system can be useful policy which improves the support and promotion of SMEs.
