According as modern dociety highly developed, a change of circumstances concerning construction marked is rapidly expanding, and expect the tendency of this change to be accelerated in the future. Up to the present, virtually, not only consrructors' recognition of a change but strategic contents corresponding to this change have been somewhat insufficient. However, shall cope with a change of circumstances cosievely free from such a thought, otherwise it s doubtful to survive, in the future, in the age of internationalization and globalization of borderless infinite competition. Therefore, this is to study the current Seem of each kind related to construction, make up a questionnaire around constructors concerned, expose the problem of the current system of each kind relate to construction by analysis of such data and devise its solution, thence bring the problem concerned with support, supply and promotion of Korean building technicians and skilled manpower preparing for 21st century, and refer to the soulution there of.

We investigated that the effects of residential type on energy balance in college students. Total sixteen college students were participated in this study, all subjects were assigned one of three groups: either school attendee students group, self-governed living students group, dormitory students group. Routine physical activity level (for 5 days including three weekday and two weekend) and food intake were surveyed. For investigation of degree of physical activity, all subjects were requested to record on their physical movements as possible as detail should be obtained. To all subjects, five-day dietary log form was given, and used for examining of calorie intake from their routine diet. There was no statistical difference in energy intake and consumption in each. However energy consumption was significantly higher than energy uptake in school attendee students group. All other groups were shown a similar energy values between energy uptake and consumption. There were no significant differences in energy intake and consumption in any of experimental groups when comparisons were made between weekdays and weekend. As far as energy uptake was concerned it was no statistical difference in any of major nutrients among groups. In conclusion, partial imbalance was found between energy intake and uptake in school attendee groups. This may be due to their more active life style than other groups'. In future studies, better controlled study should be performed not only more subjects are recruited but also minor nutrients are included for examining of energy balance.

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two experts familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further ckecked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NIOSH method 7400. The air-borne asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7-1.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 subjects, there were 4(3%) definite asbestosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.

본 연구는 학교 주5일제에 관한 학생과 교사의 의식을 조사분석하여 학교 주5일제 실시에 대응하고자 하였다. 조사 대상자는 초·중·고 학생 1558명과 교사 1077명이었다. 연구결과, 학생들은 현재 학교생활에서 공부하는 즐거움을 알지 못하고 친구들과의 교제에서 즐거움을 찾고 있는 것으로 나타났다. 학교 주5일제 관해서는 학생과 교사 대부분이 찬성하고 있으며, 찬성 이유는 여유있는 하루, 가족과 접촉시간을 갖고 취미활동을 하며 친구와 놀 수 있기 때문이라고 하였다. 교사들은 학교 주5일제로 인한 수업시수의 문제를 감축해도 상관이 없다는 반응이 많았고, 현재의 수업시수를 확보해야 한다는 의견은 적었다. 학생과 교사 대부분은 학교 주5일제는 학생들이 다양한 체험을 할 수 있는 기회를 제공하는 체제로 인식, 긍정적인 반응을 보였다. The purpose of this study is twofold: (ⅰ) to analyze students and teachers' consciousness on the proposed Five-day-work-week School System(FSS) plan; and (ⅱ) to propose a desirable direction of school management including curriculum compatible with the (FSS) plan. This study developed as follows. For the theoretical background of this study, previous research was reviewed. For the items of the questionnaire, the Japanese Ministry of Education Survey on the FSS at school was referred to. The Subjects sampled were 1558 students and 1077 teachers, The data collected from the at elementary, secondary and high school of students and teachers were statistically analyzed by using the SPSS WIN 7.5. The following are the results of the survey. First, in order to adopt the FSS plan, schools have to develop new programs connecting home and school. It is required that school develop special programs that the local community can participate in and cooperate with. Second, most of the respondents support the FSS plan because students can have more chances to be with their family, to become familiar with nature, and to attend various activities sponsored by the local organizations. Third, to argue that it is desirable to adopt the FSS plan even though school has to reduce the minimum class hours. The reason they are against the no-school-on-saturday plan is that there are many families who cannot take care of their children on Saturdays; thus, special programs for them should be prepared before the plan is put into practice. It is also required that we develop various sports or culture events for young adolescents and make up more organizations for youth. We should have school or community facilities open to young adolescents and children whose parents are unavailable to care for them. The latter should have an easy access to those facilities. From these observations, we can conclude that it is imminent to develop various programs before we put the FSS plan into practice. Schools should cooperate fully with homes and the community.

Disorders of sex development (DSD) are congenital conditions characterized by atypical development of chromosomal, gonadal, and phenotypic sex. 46, XY DSD can result from disorders of testicular development or disorders of androgen synthesis/action. Prophylactic gonadectomy should be considered in patients with 46, XY DSD because of the increased risk of gonadal malignancy. We report two rare cases of 46, XY DSD, including XY pure gonadal dysgenesis and complete androgen insensitivity syndrome, who underwent a prophylactic gonadectomy.

Background and objective: This study was conducted to establish a Plant Hardiness Zone (PHZ) map, investigate the effect of global warming on changes in PHZ, and elucidate the difference in the distribution of evergreen trees between the central and southern region within hardiness Zone 7b in Korea. Methods: Mean annual extreme minimum temperature (EMT) and related temperature fluctuation data for 40 years (1981 to 2020) in each of the meteorological observation points were extracted from the Open MET Data Portal of the Korea Meteorological Administration. Using EMT data from 60 meteorological observation points, PHZs were classified according to temperature range in the USDA Plant Hardiness Zone Map. Changes in PHZs for each decade related to the effects of global warming were analyzed. Temperature fluctuation before and after the day of EMT were analyzed for 4 areas of Seoul, Suwon, Suncheon, and Jinju falling under Zone 7b. For statistical analysis, descriptive statistics and ANOVA were performed using the IBM SPSS 22 Statistics software package. Results: Plant hardiness zones in Korea ranged from 6a to 9b. Over four decades, changes to warmer PHZ occurred in 10 areas, especially in colder ones. Based on the analysis of daily temperature fluctuation, the duration of sub-zero temperatures was at least 2 days in Seoul and Suwon, while daily maximum temperatures were above zero in Suncheon and Jinju before and after EMT day. Conclusion: It was found that the duration of sub-zero temperatures in a given area is an important factor affecting the distribution of evergreen trees in PHZ 7b.
