Adiponectin and Gut hormones(insulin, glucagon, ghrelin, PYY and GLP-1) are recently discovered peptides that are associated with lipid metabolism, insulin resistance, and control appetite. The purpose of this study was to investigate the effects of acute treadmill exercise(walking, 45min ; all-out running, 5min) on Adiponectin and gut hormones in high school ssireum player(light class, n=8; heavy class, n=8). From the experimental results, Adiponectin and ghrelin of light class were significantly higher than heavy class(p<.05), but there was no difference between pre and post exercise. Insulin level of heavy class was significantly higher than that of light class(p<.01) and no difference between pre and post exercise. Only glucagon significantly increased after exercise(p<.01), but no difference between classes. PYY and GLP-1 were no difference on classes and pre vs. post-exercise. The result of this study suggest that adiponectin, ghrelin and insulin were affected by body weight(light class vs. heavy class) and glucagon was affected by acute exercise.

This paper investigates empirically the lead-lag relation between the 'apartment price index' and 'Internet search volume'. This study uses Naver Trend Index as a proxy for Internet search volume. An increase in Internet search volume on the apartment price index indicates an increase in people's attention to an apartment. Different from previous studies exploring the relation between 'the released price index of the apartment' and 'Naver Trend Index', this study investigates the relation of the Naver Trend Index with 'the fundamental price component of an apartment' and 'the transitory price component of an apartment', respectively. The results of the Granger causality test reveal that there are bidirectional Granger causalities between the 'released price' and Naver Trend Index. In addition, the 'fundamental price component of an apartment' and Naver Trend Index have a feedback relation, while 'the transitory price component of an apartment' Granger causes the Naver Trend Index uni-directionally. The impulse response function analysis indicates that the shock of apartment prices increases Naver Trend Index in the first month. Overall, The close relationship between apartment prices and Naver Trend Index suggests that increases in the movement of apartment prices are positively associated with public attention on the apartment market.

소화가 잘 안된다, 머리가 아프다, 자꾸 마른다 등등 현대인들은 사소함(?) 신체적 고통을 흔히 호소한다. 그리고는 소화제, 두통약, 피로회복제등을 수시로 입안으로 털어넣곤 한다. 그러면서도 이러한 증상을 병으로 생각하는 사람은 없다. 그저 일시적인 현상으로만 치부해 버리고 고통과 약의 사이를 왕래한다. 물론, 몸에 좋다는 모든 것을 먹어도 나이들어 몸이 말을 듣지 않는 것은 어쩔 수 없다하더라도 사소하다고 생각하는 증상들이 경우에 따라서는 엄청난 병의 시작일 수도 있다는 것을 주위에서 수없이 경험하는 우리가 아닌가. 도대체, 소화불량ㆍ노화현상ㆍ비만ㆍ두통 이런 증상들은 어디까지가 병이고, 어디까지가 일시적인 것일까.

방청유는 오래 전 부터 일시적 녹을 방지할 목적으로 각종 금속제품의 표면처리법으로 사용되어 왔다. 방청유의 특징은 0.5~100mm 정도의 엷은 도막(塗膜)에 의하여 일시적인 녹방지 역할을 함과 동시에, 한편 녹방기 기간 후 다시 도막을 제거하는 것으로 녹방지의 기간, 포장(包裝)의 조건, 보관환경(保管環境), 사용조건 및 후처리공정의 조건 등, 각기 다른 복잡한 요건이 수반되기 때문에 이에 대응하여 방청유의 종류도 다양하게 마련이다. 특히 근간에 이르러서는 포장재의 진보와 더불어 금속제품들의 보관 및 수송환경 개선 등의 위치와 병행하여 방청유에 대한 금속표면처리의 관심도 표면화되어지고 있다. 따라서 본 논고에서는 다양다종한 방청유에 관하여 일일이 설명하기는 매우 곤란하나, 한국 공업규격을 중심으로 한 표제에 대하여 간략하게 기술하기로 하겠다.

This paper documents the increase in earnings variability (or earnings risk) during the 1990s in Korea, and investigates whether it can be accounted for by capital market opening. The variances of transitory and permanent innovations in earnings are estimated from repeated cross-section data using a simple econometric framework. The increasing time-series pattern of earnings risk among men follows the increased foreign capital presence reasonably well, but the supporting cross-sectional evidence for a causal relationship between the two is weak. However, foreign direct investment (FDI) is found to have had some non-neutral effects on workers of varying skills in such a way that transitory earnings risk of less-skilled workers relatively increased with FDI. To the extent that transitory innovations are not fully insured, this widening effect of FDI on earnings risk gap may have contributed to widening welfare gap between skilled and unskilled workers in Korea, at least in terms of "risks."

It seems like many songs have the tonality of one key in jazz standards, but there are many cases in which more than one new key could be formed, despite being a short moment. Moreover, some songs contain keys of temporary changes many times in the event that keys are changed transitionally with the sequencing of cords many times, which is called 'Transitional Modulation with Sequences. The proceeding II-V-I of the major and minor keys are used as the sequencing of cords, and the most popular type in this sequencing pattern is the downward modulation in whole-steps or half-steps. The downward modulation in the interval of whole-steps is a useful technique; for example, there should be three compositions in the adjacency circumstances when it is used twice. We could express effectively a phenomenon that feelings go up to the climax and rapidly fall down. The downward modulation in half-steps must be more dramatic because a higher comparative aspect is made between the adjacent two keys.
