This study describes the prevalence of nutrition labelling use and its association with demographic factors, knowledge and perception of nutrition labelling, and awareness of nutrition labelling usefulness among 282 college students, aged 21~23 years, in Busan Gyeongnam area. The subjects consisted of 150 of male (53.2%) and 132 of female (46.8%) students. 31.3% of male students and 50% of female students reported reading nutrition labelling always or usually, while 34.7% of male and 13.6% of female subjects reported that they don't use nutrition labelling. Although most of the subjects perceived the need of nutrition labelling, their knowledge and understanding of nutrition labelling and their awareness of nutrition labelling usefulness were not enough to apply the information from the nutrition labelling in their daily life, even in the subjects who reported reading nutrition labelling always or usually. This statement might be one of the reasons why there were no significant differences among the groups divided by nutrition labelling use in regards to the dietary habit or snack eating habit in this study. Therefore, a practical nutrition education program on nutrition labelling should be provided for the college students to increase nutrition labelling use and to apply the information from nutrition labelling in their daily life in order to maintain healthy dietary habit.

1974년도에 가동될 고리 원자력 발전소(Westinghouse 600 MWe PWR)의 핵연료 주기비를 계산했다. 적용한 가정과 가격은 현재 핵 공학계에서 인용하는 것에 기준을 두었고, 한국이라는 국지적 조건을 참작하였다. 계산방식은 가장 적절하다고 생각되는 것을 Normal로 두어, 이 보다 좋거나 나쁜 조건을 고려하였다. 마지막으로 각 Parameter가 주어진 범위 내에서 변하는 것을 Normal과 비교하고 전비용중에서 각각이 차지하는 비율을 검토했는데 그 결과 Uranium 원광비, 성형가공비가 가장 비율이 크고, 그 다음이 이자율, Plutonium Credit, Plant Capacity Factor 등의 순이었다.

건설공사의 공종 중 거푸집공사는 전체공사기간의 대략 25％를 차지하고 있으며 공사비 비율은 일반적으로 전체공사비의 10～15％, 철근콘크리트공사비의 20～30％를 차지하고 있어 구조물의 안전성, 경제성 및 작업성과 품질관리에 중요한 역할을 한다. 또한 거푸집은 콘크리트가 양생되면 곧 해체되는 가설구조물로써 작업상에서 많은 위험요소를 포함하고 있으며 특히, 아파트공사의 경우 전체 재해발생의 17％로 가장 높은 비율을 차지하고 있다. 이와 같이 거푸집공사는 가장 우선적으로 관리하여야 할 위험공종이며 전체공기를 좌우하는 주공정으로서 이를 재해발생의 측면에서 제어하는 것이 안전관리에 있어서 가장 효율적이며 큰 효과를 나타낼 수 있는 것으로 생각된다.(중략)

The purpose of this study is to analyze the impact which the plan characteristics of Residential Land Development Projects have on land price changes in the project district and to derive policy implications for the efficient promotion of these projects. For this purpose, we analyzed the promotion land price change progress of Residential Land Development Projects step-by-step. After theoretical consideration and a review of the references, 16 plan characteristics of Residential Land Development Projects affecting land price changes were selected ((1) The rate of land price change, (2) Business area, (3) Residential land ratio, (4) Commercial land ratio, (5) Semi-residential land ratio, (6) Neighborhood facilities land ratio, (7) Apartment house ratio, (8) Street ratio, (9) Park & green ratio, (10) Ratio of land for schools, (11) Site development cost for $1m^2$, (12) General residential area ratio, (13) Semi-residential area ratio, (14) Commercial area ratio, (15) Semi-Industrial area ratio, and Natural green area ratio). We used SPSS Version 20.0 to analyze the impact of the 16 selected plan characteristics on the land price changes. As a result, it was found that the land price began to rise two years (before/after?) the appointment of the district and became stabilized after the completion of the project. The plan characteristics that affect the land price changes were found to be the (2) Business area, (4) Commercial land ratio, (6) Neighborhood facilities land ratio, (8) Street ratio, (11) Site development cost for $1m^2$, and (12) General residential area ratio.

This Study is to into fuel using a torrefation reaction to food waste. When the fuel of only food waste alone, fuel value is was performed at a ratio of sewage sludge constant attempts to prevent low. Mixing ratios of food waste and sewage sludge, 10:0, 8:2, 6:4, 5:5. Regardless mixing ratio, it was possible to confirm that decreases the moisture content of 10% or less at a reaction temperature of $240^{\circ}C$ or higher. As the ratio of the reaction temperature and the sewage sludge is high, the fixed carbon content is increased. It was measured at up to 36%(mixing ratios6:4, reaction temperature $270^{\circ}C$) from the initial 1.1%. From the reaction temperature $240^{\circ}C$ satisfied with 3000Kcal/Kg or more is a SRF criteria shows the calorific value. It was possible to obtain a heating value that is increased from the raw sample approximately sextuple. As reaction temperature is heightened, Van krevelen Diagram moved to the range of Lignite range. It was possible to obtain high fuel ratio and 5,500Kcal/kg or less of a combustility index as the sewage sludge mixing ratio becomes high. Increase the fixed carbon content, than those food waste alone solid fuel into and improved fuel costs, it is necessary to ensure that the quality of the fuel is improved.

In this study, we analyse the determinants of the youth employment rate of public agencies and local public enterprises. On the other hand the youth employment rate contains information of the youth employment rate and the size of the youth employment. We use pooled tobit model and panel tobit model since dependent variable is a censored form observed only in a certain area. The results of the analysis are summarized as follows. First, the panel tobit model is more statistically significant as compared to the combined tobit model. Second, the youth employment rate is more statistically significantly higher in 2014 and 2015 than in 2011. Third, the youth employment rate in public enterprises is more statistically significantly higher than that in local public agencies. Finally, the higher the average wage is, the lower the youth employment ratio is.

This study was carried out to evaluate the nutritional properties of quality protein maize (QPM) and to select the elite lines for corn breeding. Two laboratory procedures for simultaneous identification of QPM and lysine content analysis were performed. The $BC_{1}F_{2}$ lines of KS5/QPM and KS135/QPM were analyzed with opaque-2(o2) specific SSR marker in order to differentiate the opaque-2 carrying QPM lines from the non-opaque genotypes. Although no significant difference in protein content, significant differences in lipid, ash, and crude fiber contents were observed. The composition of unsaturated fatty acid of QPM lines was slightly lower than non-QPM lines, but there was no significant difference. Sulphur-containing amino acids such as methionine and cystine showed no difference between QPM and non-QPM lines. However, lysine content of QPM lines was 38% higher than that of non-QPM lines, and the essential amino acid content of QPM lines (28.1%) was higher compared to non-QPM lines (27.1%).

This experiment was carried out to elucidate the mfluence of honeybees pollinatIOn on yield and YIeld components of soybean at the Kyungbuk Provincial Rural Development Administration from 1990 to 1991. SIX soybean varieties were cultivated in net houses with and without bees. Italian honeybees(Apis melhfem L.) were used. The Vlsiting frequency of bees in net house wIth bees was 58% higher than that of field honeybees, and it was the highest at 10 A.M. during a day. Number of pods per plant and podding ratio of soybean were higher with bees compared with Wlthout bees, especially for the varieties Paldalkong and Dankyongkong. The number of seeds per pod was not significantly different between with bees and without bees, although the percentage of three seeded pod of varieties Danyeobkong and Muhankong and one seeded pod of varieties Hwangkeumkong and Milyangkong 'was increased. The percentage of three seeded pod of Paldalkong and Dankyeongkong, however, was decreased with bees compared with without bees. At the same time no varietal difference was found in two seeded pods between with bees and without bees. Yield of soybeans was increased 0 to 12 % with bees compared with that of without bees. Yield increase was the hIghest in Paldalkong and Dankyongkong. The ratIO of soybean hybrid plant was mcreased with-bees compared with that of without-bees, especially m Paldalkong and Dankyongkong. A negative correlation was found between the ratio of hybrid plant and the duration of flowering in soy¬beans.
