Hypertension is one of the most well known risk factors for cerebrovascular or coronary heart disease and is a major public health problem. Early detection and treatment of hypertension are essential, but the compliance of treatment on hypertension is not easy to achive. Hypertensive workers are being detected by the annual screening under the Labour Standard Law in Korea but the solidified control system for them is not existing. This study about workers 'Motive-Belief-Action in non-drug and drug treatment of their hypertension would be worthwhile to interpret how the workers actually behave in coping with hypertension, and also would be advisable to construct the follow-up program in Korea. In the field research process two criteria were used to select sample group. The first criterion included the workers who were screened to be hypertensive with their blood pressure above 160/95 in this survey. The second one was used to classify study-group respondents who had known their hypertension by successive annual screening. From such criteria a total of 156 male workers were sampled in 21 industries, the author interviewed them using the structured questionnaire which consisted of Belief-Motive-Action items about non-drug and drug treatment for hypertension with open-ended question on symptom of hypertension. The summary is as follows: 1) Sixty-one percent of respondents had ever checked their blood pressure somewhere besides the annual screening. 2) Most respondents(97.2%) complained no symptoms of hypertension at all. 3) Belief level of non-drug treatment was relatively high (82.1%-64.7%), but motive(55.1%-28.2%) and action(38.5%-16.7%) levels were low. 4) Belief level of drug treatment was relatively lower than that of non-drug treatment, blue collar workers showed higher artier level of drug treatment than white collar workers, and correlation coefficient between belief and motive on drug treatment was lower in group of not-recognizing their family history of hypertension than recognized group. Such findings indicated that belief on drug treatment of hypertensive workers would be problematic. 5) White collar workers showed significant lower correlation coefficients between Motive and Action of salt restriction, restriction of fatty diet and relaxation than blue collar workers. 6) Mild hypertension group showed low levels of Motive and Action of non-drug treatment(salt restriction, restriction of fatty diet and relaxation) and also showed low correlation coefficient between Belief and Motive of above non-drug treatment.

저작권법이 규정하는 '공연'은 상식적으로 생각하는 공연의 개념보다 훨씬 그 폭이 넓다. 저작물을 가창, 연주, 연술하는 실연 행위뿐만 아니라 음반이나 영상물을 공중이 열람할 수 있도록 상영하는 행위까지도 모두 저작권법이 규정하는 '공연'에 해당이 된다. 저작권법 제29조는 공연권의 제한 사유에 관한 것이다. 제1항은 영리를 목적으로 하지 아니하는 공연과 방송에 대한 저작권 제한 사유를 규정하고 있으며, 제2항은 판매용 음반과 판매용 영상저작물을 활용한 공연에 관한 면책 요건을 규율한다. 최근 도서관의 저작물 공연이 저작권법의 주요 이슈 가운데 하나가 되고 있다. 그 가운데에는 도서관 관내에서의 영상물 열람도 공연에 해당되고, 발행 후 6개월이 경과되지 않은 저작물을 서비스할 때에는 저작권자의 사전 허락을 받아야 한다는 주장도 포함되어 있다. 이러한 주장은 정상적인 도서관 서비스를 불가능하게 만드는 것이어서 부당하며, 도서관에서의 저작물 열람과 공연을 구분할 수 있는 입법적인 조치가 시급히 이루어질 필요가 있다.

Objectives: This study was performed to examine the effective health education measures and health education programs for college students and also investigated the demands of restriction on drinking and smoking behavior in public area at the school level. Methods: The data were collected from 446 students of five universities located in Seoul and analyzed with SPSS WIN 10.0 program. Results: 1) Current drinkers were average 87.7% (male 90.1%, female 85.3%) and binge drinker was 68.4% (male 76.5%, female 60.2%). Among all drinkers, 19.4% drank more than eight times per month. As for the rate of smoking, 50.9% among the male student, and 12.1% among females were smokers. Among all smokers. the largest group (41.5%) smoked between >$11{\sim}20$ cigarettes per day. Many of the students started smoking in their middle schools (male 29.8%, female 51.5%). It implies that smoking prevention programs need to be emphasized in these schools. 2) The analysis of the correlation between drinking and smoking shows that no smoking students who drank were 66.2%, but abstainer who is smoker were only 5.7%(p=0.004). Alcohol consumption frequency and amount of smokers were higher than those of nonsmokers (p=0.000). The rate of attempts to reduce drinking was 38.1%, mainly for health reason. More than 34.5% of smoking student had made attempts to quit smoking, but succeeded only 16.9%. 3) As for the needs of moderate drinking and smoking cessation education, 67.8% among female students and 53.6% among male demand special education programs. About effective health education measures on drinking and smoking, 49.3% of drinkers and 35.2% of smokers had an inclination for health educator, and the next were video, campaign and pamphlet. 4) The largest group (45.0%) of respondents had agreed to regulate on drinking behavior, and especially 74.5% of them wants to ban the practice in most public area in school. 35.7% among female students and 27.0% among male desired to extend the non-smoking area on whole campus. The health policy for college students, through various ways, such as education, counseling service, and special program on orientation, should be employed. For public health perspectives, university and college community had to institute the detailed enforcement regulation on drinking and smoking.

This article deals with the Improvement of Compulsory Arbitration System on Trade Union and Labor Relations Adjustment Act in Korea. If a labor dispute occcur, the settlement of labor dispute must be reached for the parties' own accord. The autonomy of the parties concerned is the fundamental principle in the settlement of labor dispute. If the Rights Which are guaranteed by art. 33 Constitutional Law belong to civil liberties, we should consider Trade Union Act as the restriction of basic rights. Arbitration is a procedure which permits the most positive intervention by the arbitrator. It is carried out by an arbitration committe which is composed of three arbitrators appointed by the chairman of the Labor Relations Commission. Compulsory arbitration system of the labor for parties should be improved. In case of necessary public enterprises, more strict requirements on assembly for labor disputes should be prepared and the government should support institutions to prevent labor-management disputes by educating experts on labor-management relations and improving the quality of arbitration.

In recent years, public complaints about railroad noise by KTX and Ordinary train are increasing. Restriction of railways uses same standard without distinguishing the type of railways. According to the type of railways, the frequency characteristics of emitting noise is different. Therefore it is requested to know how vary the public response to each types of railway. The noise annoyance to three types of trains (KTX, Electric train, Diesel train) was analyzed by Jury Evaluation Test for assessing the effect of frequency characteristics. The numerical results by a Semantic Differential Method showed that annoyance response to three type of trains depended on the frequency characteristics. As a result, this study proposed that the KTX could have a bonus level of maximum 2.9dB(A) to ordinary train.

This study was conducted to establish a management plan for the Sangrim Woodlands restoration by analyzing the vegetation survey and the site characteristics of the Sangrim Woodlands Natural Monument (Natural Monument 154) in Hamyang-Gun, Gyoungsangnam-Do, Korea. According to the vegetation analysis, the species diversity by the location of Sangrim was higher near forest (1.000) than near urban (0.358) areas. Although forest occupied 53% of the Sangrim woodlands area, it is still insufficient, requiring to transform arable land, lawn, or house areas to the forest within the woodlands. Soil bulk density was increased in access areas frequently used by public, while it was decreased in closed areas. Soil hardness at 0-10 cm soil depth was generally improved in the closed areas, while became worse in the public access areas compared with the soil hardness in 2004.

Objectives : To evaluate the hypothesis that increasing ambient levels of ozone or particulate matter are associated with increased emergency room visits for asthma and to quantify the strength of association, if any, between these. Methods : Daily counts of emergency room visits for asthma, air quality, and weather data were collected from hospitals with over 200 beds and from monitoring Stations in Seoul, Korea from 1994 through 1997. Daily counts of emergency mom visits for asthma attack were analyzed using a general additive Poisson model, with adjustment for the effects of secular trend, seasonal variation, Sunday and holiday, temperature, and humidly, according to levels of ozone and particulate matter. Results : The association between daily counts of emergency room visits for asthma attack and ozone levels was statistically significant in summer(from June to August), and the RR by unit inclement of 100 ppb ozone was 1.30(95% CI = $1.11\sim1.52$) without lag time. With restriction of the period from April to September in 1996, the RR was 1.37(95% CI = $1.06\sim1.76$), and from June to August in 1995, the RR was 1.62(95% CI = $1.12\sim2.35$). In the data for children$(5\sim14yr)$, the RR was 2.57(95% CI = $1.31\sim5.05$) with restriction of the period from April to September in 1997. There was no Significant association between TSP levels and asthma attacks, but a slight association was seen between PM10 levels and asthma attacks in a very restricted period. Conclusion : There was a statistically significant association between ambient levels of ozone and daily counts of emergency room visits for asthma attack. Therefore, we must make efforts to effectively minimize air pollution, in order to protect public health.

Objectives: Many governments have imposed-and are still imposing-mobility restrictions to contain the coronavirus disease 2019 (COVID-19) pandemic. However, there is no consensus on whether policy-induced reductions of human mobility effectively reduce the effective reproduction number (Rt) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several studies based on country-restricted data reported conflicting trends in the change of the SARS-CoV-2 Rt following mobility restrictions. The objective of this study was to examine, at the global scale, the existence of regional specificities in the correlations between Rt and human mobility. Methods: We computed the Rt of SARS-CoV-2 using data on worldwide infection cases reported by the Johns Hopkins University, and analyzed the correlation between Rt and mobility indicators from the Google COVID-19 Community Mobility Reports in 125 countries, as well as states/regions within the United States, using the Pearson correlation test, linear modeling, and quadratic modeling. Results: The correlation analysis identified countries where Rt negatively correlated with residential mobility, as expected by policymakers, but also countries where Rt positively correlated with residential mobility and countries with more complex correlation patterns. The correlations between Rt and residential mobility were non-linear in many countries, indicating an optimal level above which increasing residential mobility is counterproductive. Conclusions: Our results indicate that, in order to effectively reduce viral circulation, mobility restriction measures must be tailored by region, considering local cultural determinants and social behaviors. We believe that our results have the potential to guide differential refinement of mobility restriction policies at a country/regional resolution.

Background: To explore the relationship between polymorphisms of interleukin17 (IL-17) gene(A-832G 7488A/G) and the susceptibility to silicosis, a risk factor for lung cancer. Materials and Methods: A total of 113 silicosis patients and 116 workers without silicosis were enrolled in the case-control study. IL-17A A-832G and IL-17F 7488A/G polymorphisms were evaluated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The frequencies of AA,GG and AG of IL-17A A-832G locus in the case and control groups were 46.9%, 8.0%, 45.1%, and 49.2%, 7.6%, 43.2%, respectively, with no significant differences (p>0.05).The GG genotype in the IL-17F (7488A/G) locus was not found. The frequencies of AA and GA of IL-17F 7488A/G locus in the case and control groups were 84.1%, 15.9% and 66.4%, 33.6%, respectively (p<0.05). Analysis of combined effects showed that the individuals with GG+AG genotype of IL-17A and GG+GA genotype of IL-17F are protected against silicosis (OR=0.469). Conclusions: IL-17F 7488A/G is associated with susceptibility to silicosis, and G allele may have a protective effect. No relationship was found between IL-17A gene polymorphisms at A-832G and silicosis.

Beam-forming 방식을 적용한 배열 안테나의 무선전력전송(WPT)은 송신기와 수신기를 접촉하지 않고 서로 떨어져도 높은 효율의 무선전력전송이 가능하다. 하지만 이 방식은 송신기와 수신기의 떨어진 거리에 따른 전자파에 대한 인체안전기준을 만족해야 사용할 수 있다. 본 논문에서는 시뮬레이션을 통해 2.4 GHz용 $4{\times}8$ 배열 안테나를 모델링하고 배열 안테나의 단일 안테나에 각각 1W의 2.4 GHz 정현파를 인가하여 배열 안테나로부터 떨어진 거리에 따른 전기장 세기 및 머리에 대한 10 gram 평균 SAR (Specific Absorption Rate)를 구하였다. 그리고 이 값들과 2018 ICNIRP (International Commission on Non-Ionizing Radiation Protection) 가이드라인 초안의 인체안전기준치와 비교하였다. 그 결과, 원거리장의 전기장 세기로부터 도출된 전력밀도가 $33.257W/m^2$로 직업인에 대한 전력밀도의 인체안전기준치는 만족하나 일반인에 대한 전력밀도의 인체안전기준치를 초과하였다. 10 gram 평균 SAR 또한 인체안전 기준치를 초과하였다.
