The purpose of this study was to investigate the differences in food and nutrient intake by smoking status among Korean. Food and nutrient intake in relation to smoking status was studied in 7,370 adults, aged 20 years and older in 1998 Korean National Health and Nutrition Survey, in which 24 hour recall method was used for dietary survey. Information of subject's smoking status was collected by interview as a part of health behavior survey. Analysis of variance was used to test the differences in food and nutrition intake among subjects following after Duncan's multiple range test among four different smoking exposure categories. Food intake of male ex-smoker was the highest in most of the food groups among the four groups of daily current smoker, occasional current smoker, ex-smoker and never smoker. There was significant differences observed in food intake of sugar, fruits, beverage, seasoning by the smoking status. It had been also observed that significantly high intake of energy from carbohydrate in non smoker compare to current smoker especially in male subjects. Fiber and vitamin C intake was also higher among non-smoker (never smoker and ex-smoker) than current smoker. In general, food and nutrient intake pattern of ex-smoker resembled those of never smoker than those of current smoker. Not likely the observation from European and American studies, fat intake was not statistically different between smoker (current) and non-smoker (ex-smoker and never smoker) among Korean.

FMS has received a great deal of attention in the past two decades as a possible breakthrough for the new technologies in manufacturing. Some people say that the era of FMS has just begun. We have seen the potential benefits of FMS to the manufacturing industries. But it seems that FMS has generated a large number of problems to solve. The objective of this paper is to provide a groundwork for researches in the area of FMS by discussing the current status and prospect. The current status of installations and operations of FMS worldwide is reviewed. U.S.A., Japan, Western Europe, U.S.S.R. and Eastern Europe, and domestic status are discussed briefly. The current status of researches that are related to the FMS is also reviewed. Lastly, the prospect of hardware and software is discussed.

According to consumer's needs of agriculture like vegetables and paprika, etc. are being various, the agricultural facilities are diversifying. In current trends of agricultural facilities, area and heigh of those is becoming bigger and higher to plant various agriculture. But the software and support for constructing the various agricultural facilities is insufficient. And understanding the current status of agricultural facilities to help farmer and users of agricultural facilities is needed. Therefore, in this study, the status of the agricultural facilities are examined by interviewing farmer and users of facilities. The results of this survey on the status of agricultural facilities are presented. Firstly, the construction cost of facilities is most important. Secondly, the materials and technology for constructing facilities is also important.

Purpose: In the course of the domestic environmental impact assessment, the current status survey was improperly conducted, and the issue of false and inaccurate environmental impact assessment reports has been raised several times recently through media reports. Research design, data and methodology: There is a continuous demand for improvement measures for the current status measurement method, such as having difficulties in securing a normal measurement date in consideration of equipment operation and rainfall days in the field. Results: In addition, in order to grasp the general air quality status of the evaluation target area, it is necessary to check the various current status concentrations by season and time series per year. However, there is a problem that is currently being carried out based on limited results such as measurement for 1 day or 3 days. Conclusions: Therefore, in this study, based on the national atmospheric measurement network, an inverse distance weighted (IDW) interpolation method was applied to calculate the current state concentration. This study suggested a method to use it in preparing the air quality item in the environmental impact assessment report.

In this paper, we develop a nonparametric Bayesian methodology of estimating an unknown distribution function F at the given survival time with current status data under the assumption of Dirichlet process prior on F. We compare our algorithm with the nonparametric maximum likelihood estimator through application to simulated data and real data.

When modeling event times in biomedical studies, the outcome might be incompletely observed. In this paper, we assume that the outcome is recorded as current status failure time data. Despite well-developed literature the routine practical use of many current status data modeling methods remains infrequent due to the lack of specialized statistical software, the difficulty to assess model goodness-of-fit, as well as the possible loss of information caused by covariate grouping or discretization. We propose a model based on pseudo-observations that is convenient to implement and that allows for flexibility in the choice of the outcome. Parameter estimates are obtained based on generalized estimating equations. Examples from studies in bile duct hyperplasia and breast cancer in conjunction with simulated data illustrate the practical advantages of this model.

우리나라에 서식하는 파충류상과 분포 현황을 파악하기 위해 제2차 전국자연환경조사, 국립공원자연자원조사, 개인 조사결과 등이 분석되었다. 그 결과 우리나라에 서식하는 파충류는 총 2목 7과 21종으로 확인되었다(장수거북, 바다거북, 붉은바다거북, 바다뱀, 얼룩바다뱀, 먹대가리바다뱀 등 해양 파충류 제외). 또한 분류학적으로 많은 논쟁이 있는 도마뱀류, 장지뱀류, 뱀류에 대한 분류학적 고찰이 시도되었다. 그러나 추가적으로 해양파충류에 대한 연구가 필요할 것을 판단된다.

Purpose : The purpose of this survey was to investigate the health status (food intake, exercise, smoking, drinking, stress, social support) of North Korean Refugees in Gwangju metropolitan city and Jeonnam province. Method : Data were collected by self-reported questionnaire from 61 North Korean Refugees from March 20 to April 20, 2005. The data were analyzed by descriptive statistics using SPSS win 12.0 programs. Results: In current health status, 42.7% of the subjects were in poor health. In exercise status, 32.8% of the subjects practiced exercise regular basis but only 13.1% did it 3-4 times per week. In smoking status, 26.2% of the subjects were current smokers and 81% were nicotine dependent. In drinking status, 37.7% of the subjects were current drinkers, 48% were problematic and 17% were alcohol dependent. In stress status, 42.7% of the subjects were in psycho-emotional, 49.2% in physical and 19.6% in behavioral stress. The mean score of social support was 24 out of 54 points showing a little low relatively. Conclusion : These findings showed that the health conditions of Saeteomins were poor relatively. Therefore, health care programs should be started for these Saeteomins in order to improve their health status.

The entire land of Southern Iran faces problems arising out of various types of land degradation of which vegetation degradation forms one of the major types. The present work introduces a model developed for assessing the current status of hazard of vegetation degradation using Geographic Information System (GIS). This kind of assessment differs from those assessments based on vulnerability or potential hazard assessments. The Sadra watershed which covers the upper reaches of Marharlu basin, Fars Province, has been chosen for a hazard assessment of this type of degradation. The different kinds of data for indicators of current status of vegetation degradation were gathered from collecting of field data and also records of the governmental offices of Iran. Taking into consideration three indicators of current status of vegetation degradation the model identifies areas with different hazard classes. By fixing the thresholds of severity classes of the three indicators including per cent of vegetation cover, biomass production and ratio of actual biomass to potential biomass production, a hazard map for each indicator was first prepared in GIS. The final hazard map of current status of vegetation degradation was prepared by intersecting three hazards in the GIS. Results show areas under severe hazard class have been found to be widespread (89 %) while areas under moderate and very severe hazard classes have been found less extensive in the Sadra watershed. The preparation of hazard maps based on the GIS analysis of these indicators will be helpful for prioritizing the areas to initiate remedial measures.
