This study is to identify urban characteristics affecting obesity of elementary, middle and high school students. Most of previous studies in Korea discussed healthy city focusing on adults. We list up possible urban characteristic factors that are considered to affect adolescent obesity from previous studies, and then conduct regression analysis to find policy implications in urban planning. Based on the physical examination data of adolescent students in Seoul from the Ministry of Education, we set the rate of obese students by school as a dependent variable. Urban characteristic variables are set as explanatory variables, and measured by buffer analysis within 500m, 1000m and 1500m. The result of regression analysis shows that the obese rate of students increases with adults' lower education level, higher rate of non-apartment houses, older age of houses and more homogeneous land use. However, the result does not indicate that population density, accessibility to public transportation and the urban park are significant factors for adolescent obesity. Based on this result, urban planning policy for promoting adolescent health should be discussed further.

We present a method that enhances the rendering speed of z-buffer algorithm using temporal coherence between two contiguous frames on fixed viewing conditions. Conventional z-buffer algorithm stores depth value for each pixel on a view plane while rendering some polygons, then it determines the visibility of the remaining polygons based on the stored depth values. If we can get color and depth information for some polygons without rendering, it is possible to generate an image by rendering only the remaining ones. In case of high frame rate, we can find the fact that sets of static polygons of the two contiguous frames are almost the same. This temporal coherence enables us to get the color and depth information of static polygons efficiently. Our algorithm stores color and depth information of static polygons and reuses it for generating the next frame. This method can be easily implemented since it does not require complex data structure and modification for conventional z-buffer algorithm. Also it is adequate for hardware implementation.

Using youth panel data, this study attempted to diagnose the effect of residential characteristics (housing type and housing type) and various household background variables on the implementation of youth NEET (Not in Employment, Education or Training), and to suggest appropriate policy directions. As a result of the analysis, it was found that young individuals residing in unfavorable living conditions such as those who rent on a monthly basis or live in multi-household, villa, or officetel settings, had a higher likelihood of transitioning to NEET. Those who received financial support from their parents were more likely to transition to NEET. Therefore, comprehensive youth NEET support policies such as customized housing and job policies according to the characteristics of NEET should be established. In particular, even though they have reached adulthood, it is shown that the likelihood of becoming NEET is very high for youth who live together with their parents without being economically independent or who receive financial assistance from their parents. In order to mitigate and prevent these young people from NEET transition, transitioning from school to the labor market should be facilitated with policy support.

The Naeseong Stream is a meandering sand-bed stream flowing through mountains and has so long maintained its geomorphological uniqueness characterized by extensive braided bare bars. Recently, its long-lasting landscape has been changed due to encroachment of vegetation. In this study being a part of long-term monitoring research morphological changes of the 56.8 km long study reach of the Naeseong Stream, which occurred during the period of 2012 - 2016 were analyzed. Airborne LiDAR and terrestrial cross-section surveys were carried out. Hydrological and on-site investigation data were also collected. Among the main four sites, two bend reaches showed point bars enlarged, while along the other two straight reaches mid-channel bars were either newly formed or increased in area and height. At the highest deposition point of each bar, vertical changes which were caused by one or two times of sediment deposition amounted to 0.6 - 1.4 m. On the contrary channel bed degradation was not obvious. Overall morphological changes in the study reach were attributed to deposition of sediment which occurred during the flood in July 2016 on the bar surfaces vegetated during the precedent dry seasons. These kind of geomorphological processes are thought to be the same as those related to the existing mid-channel islands along the mid- and downstream reach of the Naeseong Stream.

We compared the physicochemical properties of meat and viscera with regard to the age of abalone (1-, 2-, 3- and 4-year-old abalone). With respect to total amino acids, the level was highest in 1-year-old abalone, at $19,046.00{\pm}548.53\;mg%$, whereas 4-year-old abalone had the lowest value of $15,770.44{\pm}454.19\;mg%$. In the viscera, 3-year-old abalone had the greatest level of total amino acids, at $16,575.10{\pm}477.37\;mg%$, whereas 1-year-old abalone had the lowest, at $14,947.26{\pm}430.48\;mg%$. The level of total free amino acids in meat tended to increase with age whereas that of the viscera fell. The level of polyunsaturated acids decreased with age in meat. The concentration of chondroitin sulfate in both meat and viscera tended to increase with age. This was especially noticeable in meat. The level in 1-year-old abalone, $9.03{\pm}0.23%$ (w/w), rose to $14.17{\pm}0.33%$ in 4-year-old abalone, with statistical significance. On the other hand, the collagen level in both meat and viscera decreased with age. Again, this was particularly noticeable in meat, where the concentration in 1-year-old abalone, $199.70{\pm}5.00\;mg/g$, fell remarkably to the value of $47.86{\pm}1.10\;mg/g$ in 4-year-old abalone. We have thus provided basic data for research on abalone.

This study was carreid out to investigate present comsuming behavior and consumer preference of SEAFOODS as a stuff in KIMCHI making, adopting a questionaire survey for 500 housewives living in Korea except Chejudo Province. Frequency distribution and percentage of preferences were measured. Out of total housewives responded, 65.5% consider, THEY SHOULD EAT KIMCHI DAILY. Which conforms, kimchi is still an important side dish at most of the households On the other hand, some others consider EATING KIMCHI EVERY DAY is not neccesary(6.0%) or dislike it(0.5%). This result might suggest that kimchi may or may not be an essential sidedish for every households in the future. 96.3% of Housewives used fermented salited fish and 45% used seafoods as a staffing in making kimchi. Major reasons for adding seafoods in kimchi were: it improves teste and flavor(79.5%) and nutritional value(54.2%). Reasons for rejecting seafoods as a stuffing in making kimchi were: it worsens taste and flavor(13.5%), hygenic treatments of seafoods are below the necessary level(13.5%) and shelf life become shorter(12.8%), respectively. Among the fermented salted sauces, 84.9% and 69.1% of house wives responded as anchovy and shrimp sause were most favorite(base) material in Kimchi making, respectively. Out of total seafoods utilized in making kimchi,76.4%, 54.7% and 31.4% of housewives responded as oyster, small shrimp and sea-staghorn as the favorite seafoods in Kimchi making(raw material). Majority of housewives responded to develop it's taste and flavor to meet that of international one(86.5%) and that hygienic level(treatments) should be upgraded(50.9%).

The most difficult problem one faces in estimating North Korea's GNP is the lack of basic national income data. In addition, there is no appropriate foreign exchange rate available to convert North Korea's GNP to dollar values. The physical indicators method is particularly useful in estimating North Korean GNP because it requires only a modest amount of data and obtains dollar GNP directly by applying a relationship between physical indicators and GNP, which is estimated from reference countries, to physical indicators of North Korea. The estimated result of North Korean GNP in 1990 is 27.1 billion dollars and per capita GNP 1,268 dollars. The trade participation ratio (Trade/GNP) implied by the GNP estimate was plausible and so was the ratio of fiscal expenditure to GNP. This paper examined the physical indicators method's logic, the quality of the North Korean data that was used in the estimation, and the plausibility of estimation result. Relatively simple data requirement, comparative ease of computation and plausible estimation results suggest that use of physical indicators method could enhance the reliability of North Korean GNP estimate.
