This study was carried out to investigate the perception on nutrition labeling of the processed foods among elementary school teachers in Busan. The survey was conducted from November 1 to November 30, 2008 by questionnaires and data which were analyzed by SPSS program. The results are summarized as follows. Ninety five point seven percent of the male teachers and 98.2% of the female teachers recognized the nutrition labeling (NL). The necessity of a NL system and comprehension of NL were higher in the female group than the male group. NL was trusted by 22.9% of male teachers and 19.7% of female teachers. The main reason for checking NL of the teachers was for food safety. For the most important NL items at purchasing the food, the teachers replied 'trans fatty acid' and 'cholesterol'. Five point seven percent of male teachers and 17.0% of female teachers were educated for NL. Seventy two point nine percent of males and 91.0% of females recognized the necessity of NL teaching. It is necessary to prepare education programs for both teachers and students about accurate recognition of NL. (Korean J Community Nutrition 14(4) : 430${\sim}$440, 2009)

Rural community in Korea being changed to aging community, declining population and income loss by the industrialization and the urbanization. The weak class in rural is confronted with more poorly environment. So it is needed to check the quality of the weak class's house in rural. Basically proposes of this paper is to find ways about rural housing improving and the vitality of rural community. This paper contents rural housing problems through the paper review and house repair characteristics for the weak class. Data for statics analysis were obtained from house repair support program for the weak class in Jeonnam province from 2011 to 2012. The results of this paper are as follow: First, house repair items ranking for the weak class in rural was insulation & heating, toilet, structure, indoor environment, electricity, outside and kitchen & waterproof. This result was reflected that weak class's energy bills is high ratio compared with income. Second, health facilities were improved for the socially disadvantaged's convenience in considering that most of weak class is a senior. Last, most of houses for weak class in rural are old clay wall and block wall. So these houses are reinforced the wall for structural safety.

This paper presents a landscape design for the meeting plaza around the "Myeonmok" subway station. The site is located at 120-1 Myeonmok 1-dong, Jnngrang-gu, Seoul, and its area is approximately $2,664.7m^2$. The goal of the design was to make an environmentally friendly meeting and rest place which was related to the subway station. To achieve this goal, concepts of history, tradition, sense of place, community, environmental friendliness, and function were developed. For history, stone sculpture and art tiles symbolizing the paleolithic area were introduced because the site is located near an archaeological site of paleolithic min. For tradition, considering that the site is a 'sailing ship' form in terms of Pungsu theory, a sculpture symbolizing a sailing ship and paving patterns symbolizing waves were introduced. For asense of place, a grass hill, a waterfall and a pond symbolizing an old meadow for horse pasture was introduced. In addition, a multi-purpose round plaza as a meeting place for local community and subway users was proposed. A zelkova grove symbolizing a village forest was proposed for a restand relaxation area. All areas were designed to be environmentally friendly and barrier-free. Concepts for a defensible space wereadapted for safety because the site was a crime-prone area.

The membrane-aerated biofilm reactor (MABR) is a promising municipal wastewater treatment process. In this study, two cross-flow MABRs were constructed to explore the carbon and nitrogen removal performance and bacterial succession, along with changes of influent loading shock comprising flow velocity, COD, and NH₄-N concentrations. Redundancy analysis revealed that the function of high flow velocity was mainly embodied in facilitating contaminants diffusion and biosorption rather than the success of overall bacterial populations (p > 0.05). In contrast, the influent NH₄-N concentration contributed most to the variance of reactor efficiency and community structure (p < 0.05). Pyrosequencing results showed that Anaerolineae, and Beta- and Alphaproteobacteria were the dominant groups in biofilms for COD and NH₄-N removal. Among the identified genera, Nitrosomonas and Nitrospira were the main nitrifiers, and Hyphomicrobium, Hydrogenophaga, and Rhodobacter were the key denitrifiers. Meanwhile, principal component analysis indicated that bacterial shift in MABR was probably the combination of stochastic and deterministic processes.

Post-harvest handling and hygienic level of aquatic products significantly affect the quality and level of safety. Cold chain control is one of the determining factors for the quality of fish and the bacterial community that grows on the fish. Identification of spoilage bacteria and pathogens in aquatic products must be made because it will determine the physical and chemical quality. A molecular identification method with high sensitivity is the solution. This study aims to identify the quality of fish and bacterial communities that grow. The research procedures included sample collection, pH measurement, drip loss measurement, transportation and cold storage treatment, DNA extraction, DNA sequencing, sequence analysis, and bioinformatics analysis. The conclusion obtained from this study is that the simulation of the cold chain system applied to eastern little tuna does not significantly affect changes in the water activity value, pH, and drip loss. The insignificant change indicates that the eastern little tuna samples are still in good quality. The bioinformatics analysis showed the highest diversity and abundance of the bacterial community came from the Gammaproteobacterial class.

The purpose of this study is to compare the relative risk of metabolic syndrome (MS) in middle aged adults with different body weights. 155 subjects living in urban Beijing were recruited from 24 neighborhood committees of urban Beijing. They were divided into normal weight, overweight and obese groups according to their BMIs. The general information of the subjects was collected using an interview-administered questionnaire. Standard procedure was followed to measure subject's weight, height and waist. Biochemical parameters (total cholesterol (TC), low- and high­density lipoprotein cholesterol (LDL-C ; HDL-C), triglyceride (TG), and fasting glucose) and blood pressure were also determined. The results indicated that the systolic and diastolic blood pressure, HDL-C of obese group was lower than that of the normal weight group. Fasting glucose of obese males was significantly higher than that of normal weight males. No significant difference of fasting glucose was found among female groups. No significant difference of TG was found among male groups, while TG of overweight and obese females was both significantly higher than normal weight females. There was no significant difference of TC and LDL-C among normal weight, overweight and obese groups in both males and females. The MS rate of obese males was significantly higher than the normal weight and overweight males, as was the female. The relative risk of MS in obese group was about 11 times higher (OR=11.249, $95\%CI$ = 3.812 - 33.191) than the normal weight group after adjusting for age, gender, smoking, drinking, family economic level and education status. It is concluded that obesity contributed to lower HDL-C, hypertriglyceride, hypertension and MS after controlling the effects of age, gender, socioeconomic status, alcohol drinking and smoking. Obese individuals have a higher risk of having MS than their normal weight counterparts.

This study was not intended to analyze out the realities of the safety accidents in school. The purpose of this study was to find out the personality of elementary school students in 6th grade and analyze the relationship between the personality of elementary school students and the safety accidents in the school. We made a visit 12 elementary school personally in the B city of Gyeonggi Province and gave out 552 questionaries in order to accomplish the purpose of this study. And we analyzed the 501 answer data except the unfittable data 51 sheets-in case of no answer or untruthfulness. The inspection of the personality used the Eysenck Personality Questionnaire(EPQ) and the questionnaires of the safety accidents in the school were reorganized of the questionnaires which were used in Chun-Ok, Joen(1997) and One-Yong, Kim(1999)'s study to correspond with our purpose of study. Answer sheets were gone through the t and x2 test by using the program of SPPS. First, elementary school students are in the formative period in the life of a man. So many students's personality was in the middle group rather than in high and low group. In regard of the distintion between the boy students and the girl students, the boy students had higher score in Psychoticism(P) but the girl students had higher score in Neutroticism(N). And Lie(L) was showing a little more score in the girl students. Second, there was significant difference in the investigation of safety accidents in school according to sex distinction. 1) Comparing the boy students and the girl students, the rate of accidents was higher in boy rather than girl. And there was significant difference. 2) Comparing the grade of the school, the rate of accidents was higher in upper grade than lower grade both girls and boys. 3) In the kind of accidents, the traumatic Injuries were very popular and the next were contusions. There was significant difference in the traumatic injury and nosebleed. 4) The results of injured parts showed that the injuries of foot, leg, hand, arm hold a large majority. And there was a significant difference in head, face, foot, leg and etc. 5) Most accidents broke out during the break time and then accidents happened after school were the next. The flowings were lunch time and class time. There was a significant difference in accidents happened during the class, break time and lunch time. 6) Comparing the subjects, the most accidents broke out in the class of physics. 7) Among the cause of accidents, one's own carelessness was showing the highest rate. There was a significant distintion in the fight and game. 8) The safety accidents took place most in playground, and there was a significant difference. 9) Being slight wound was showing almost in the degrees of damage. And there was a significant difference. Third, the boy students were not showing the significant difference in relation to the personality, the frequency of accidents and the degrees of damage. But the girl students were showing the significant difference in relation to the Extraversion-Introversion(E) and the frequency of accidents. And there were a significant difference between E and N. Also they were showing the intense damages.

본 연구에서는 수치해석모형을 통하여 수위변동시 필댐의 거동 특성을 분석하고 저수지의 안전관리 방안을 고찰하였다. 수치해석 프로그램(GTS NX 및 LIQCA)을 이용하여 필댐의 상·하류측 Shell 및 Core에서 수위승강에 따른 소성전단변형률, 수평변위, 응력경로, 간극수압 등을 분석하였다. 제체의 거동을 분석한 결과, 제체 내의 수위가 빠른 속도로 상승하면 간극수압 및 변위 또한 급격하게 증가하는데, 수위의 상승은 제체 내의 간극수압 증가와 제체의 포화도 증가를 유발하며, 제체의 유효응력을 감소시키는 것으로 나타났다. 이러한 수위승강 시 필댐의 거동 특성은 제체의 강도 및 강성이 저하되는 원인이 되고, 침투로 인해 발생하는 제체의 변형에 의해 소성전단변형률이 축적되어 변위 증가를 유발하는 것으로 판단된다. 본 연구를 통해 저수지의 정밀안전진단 상태평가 기준 개선안을 제안하였으며, 향후 저수지 안전진단지침 개정안 마련 시 기초자료로 활용될 수 있을 것으로 판단된다.

The number of household living alone including young single adults has gradually increased. The purpose of this study is to examine the demand on housing options, additional space, shared space, community facilities, housing service for young adults living alone including college students. A total of 180 questionnaire were collected and analyzed. For housing location, commuting distance is the most important feature and amenities are the second important feature. For additional space, there is a significant difference between male and female single residents. Female residents want to install dress room most while male adults want to have a study room. For the shared house option, single adults concerns housing fee and living cost most. However, female adults concern safety and security issues much more than male ones do. The degree of preference to community facilities varies between male and female single residents. The findings suggest more differentiated approaches are needed for alternative housing options for male and female residents.
