Young-Son Cho,Sok-Dong Kim,Bon-Chul Koo,Won-Ha Yang,Jin-Chul Shin,Young-Han Yun1,Joung-Gon Kim 한국작물학회 2008 한국작물학회 학술발표대회 논문집 Vol.2008 No.10

Changing climate could be effect on the growth of soybean and seed yield, so we evaluated newly developed soy cultivars in the point of the physiological characteristics by changing temperature and light intensity in the phytotron. Two soy cultivars evaluated in three temperature levels (T1, 20/15; T2, 25/20; T3, 30/25oC at day/night) the pot experiment in phytotron between winter and spring in 2006 and spring and summer in 2007. Increased temperature from T1 to T2 and T2 to T3 enhanced crop growth parameters greatly and shortened growth duration and increased seed yield, however, grown in winter and spring enhanced too much plant height, so plant stems were very slim and weak and it resulted in the lodging problem. In this results we can estimate warming in Korean peninsular which might be increase temperature with low light intensity, so plant breeders and physiologists should be develop improved lodging resistance cultivars under low light intensity and high temperature.

This report presents a young-aged man with Hirayama disease who had muscle atrophy and weakness strictly confined to the C8/T1 myotome that consistently accorded with electromyographic results. In the magnetic resonance imaging (MRI) evaluation, there was only a prominent isolated spinal cord atrophy without any typical flexion MRI features of Hirayama disease. We speculate that it may be possible to have only isolated spinal cord atrophy as a limited form in Hirayama disease even in the absence of anterior displacement of the dura in the flexed position. These findings emphasize the importance of understanding both typical and atypical limited findings of the MRI imaging features of Hirayama disease, because it’s critical to distinguish Hirayama disease, mostly showing benign course, from fatal conditions like amyotrophic lateral sclerosis.

The objective of this study was to determine the effect of macrophages on growth of human colon cancer cells. The results showed that co-culture of colon cancer cells with macrophages inhibited the growth of colon cancer cells (HCT116 and SW620) depending on the number of macrophages, RAW 264.7 cells, and activated THP-1 cells accompanied by down regulation of pSTAT3 in cancer cells. We also found that expression and release of cancer cell growth inhibitory cytokines, IL-1 receptor antagonist (IL-1ra) and IL-10, was increased in macrophages. Blocking of the STAT3 pathway with specific inhibitor and siRNA of STAT3 abolished the growth of colon cancer cells and expression of IL-1ra and IL-10. In addition, neutralization of IL-1ra and IL-10 with antibodies resulted in reversal of macrophage-induced inhibition of cancer cell growth. These data showed that IL-1ra and IL-10 released from macrophages inhibit growth of colon cancer cells through inhibition of the STAT3 pathway

거시경제 변수를 활용한 주택담보대출 연체율에 미치는 결정요인에 관한 연구

이석원(Lee, Seok-Won),황윤구(Hwang, Yun-Goo),윤영의(Yoon, Young-Eui) 한국부동산정책학회 2017 不動産政策硏究 Vol.18 No.3

In the second quarter of 2017, the size of the household debts has been reaching 1,388 trillion won. And, because the size of the housing mortgage loans has been closing in upon 560 trillion won, around 40.3% has been crowded in the housing demand funds. Regarding this, there is no choice but for the influence on the entire economy to be high according to the increase of the delinquency rate in case the economy worsens or the recession continues. This study intends to suggest the implications regarding the housing mortgage loans in the long-term viewpoint through the influence evaluations of the macroeconomic variables related to such housing mortgage loan delinquencies. The macroeconomic variables that were used were the housing mortgage loan delinquency rate (TOD), the price index of the average buying and selling of the real apartment transactions (APT_PRICE), the new housing mortgage loan interest rate (HINTEREST), the index of the industrial products (IIP), the amount of money in circulation (M2), the monetary amount of the housing mortgage loans (HML), the amount of the apartment transactions (TRADE), and these were unfolded in the viewpoint of the relationship with the real estate market and the currency policy. As a result of the unit root test, it appeared that, regarding the amount of the apartment transactions, the time series raw data had been maintaining the stability. And it was able to find out that the data of the remaining variables, including the housing mortgage loan delinquency rate (TOD), had been getting stabilized through the primary difference. Because, as a result of a co-integration test, at least 6 variables possess the linear, the selection of the model used the VEC model, and, regarding the optimal differential, the 1st model was selected based on the SC (Schwarz Criterion) value. As a result of taking a look at the granger causality relationship, it appeared that the variables that had the influences on the housing mortgage loan delinquency rate were the price index of the average buying and selling of the real apartment transactions (APT_PRICE), the new housing mortgage loan interest rate (HINTEREST), the index of the industrial products (IIP), the amount of money in circulation (M2), and the amount of the apartment transactions (TRADE). As a result of analyzing the VECM (Vector error correction Model) short-run equilibrium relationship, it appeared that the housing mortgage loan delinquency rate were influenced by the index of the average price of the buying and selling of the real transactions of the apartments and by the index of industrial products. As a result of a reaction to a shock, the positive (+) correlation appeared between the housing mortgage loan delinquency rate and the amount of the transactions of the apartments (TRADE) and, also, the interest rate of the new housing mortgage loan (HINTEREST). Eventually, regarding the housing mortgage loan delinquency rate, if the interest rate goes up, right away, an increase of the delinquency rate takes place. And, it appeared that, if the monetary amount of the housing mortgage loan becomes big, the delinquency rate decreases. This is because the delinquency rate has the influences on the incomes and others of the like, it can be under the control of the interest rate policies. The meaning of this research is that it investigated about the relationship with the housing mortgage loan delinquency rates by considering the indices in the real estate market and the currency policies at the same time. And, it is that, in the condition in which the scale of the housing mortgage loan having become big at present, raising the interest rate can aggravate the confusion more in the market. As a result, with regard to the proceeding with the real estate policies, the prudent and macroscopic approach is needed. And the researches on the relationships of the indices will be needed more in the macroscopic viewpoint.

Scalp hair loss has increased recently in young-aged people as well as middle-aged people, and although there are no serious in health problems, scalp hair loss may significantly affect a variety of psychological and social experiences and the individual's quality of life. DREAMMO scalp lotion is composed of several plant extracts which are known to be used as oriental medicine to prevent hair loss or promote hair growth in alopecia. This study was carried out to investigate the effect of DREAMMO scalp lotion on hair growth in an alopecia model of C57BL/6 mice. Mice were divided into three experimental groups including control, DREAMMO scalp lotion and 3% Minoxidil (MXD). The test compounds were topically treated with 0.2 ㎖ per mouse per day for 4 weeks. The hair growth was determined photographically and histologically in an alopecia model of C57BL/6 mice. After 3-4 weeks, DREAMMO scalp lotion significantly increased hair growth compared to the controls in the dorsal skin of C57BL/6 mice. DREAMMO scalp lotion also promoted the elongation of hair follicles than the controls. These results suggest that DREAMMO scalp lotion has a hair growth activity and can be useful for the treatment of alopecia.

탈북청소년에 대한 신변보호경찰관의 효율적인 지원방안

김윤영(Kim, Yun-young),이상원(Lee, Sang-won) 호남대학교 인문사회과학연구소 2011 인문사회과학연구 Vol.33 No.-

국내에 정착한 탈북청소년은 북한체제 및 탈북과정에서 겪은 육체적ㆍ정신적 피폐에 따른 스트레스로 우리사회에 쉽게 동화되지 못하고 ‘주변인’으로 머물며 우울함과 불안감 정도가 남한 청소년들보다 심하여 외부자극에 대한 과잉반응을 보일뿐만 아니라 사회적 적개심으로 표출되어 일탈행위로 이어지고 있다. 김정일 이후 북한체제의 변화가 예상되고 통일시대가 구호가 아닌 현실 가능성으로 다가오고 있는 가운데, 통일세대라 할 수 있는 탈북청소년들의 보호문제는 통일 이후 함께 해야 할 수백만 명의 북한청소년들을 이끌어 가기 위한 과제이자, 진정한 남북사회통합의 성패를 가름하는 바로미터가 될 수 있다. 신변보호경찰관은 탈북자의 사회정착 성공여부를 결정하는 데 직접적인 영향을 미칠 뿐 만 아니라 남북통일의 자산인 탈북청소년이 건전한 통일 세대로 성장할 수 있도록 보호지원 하는데 중요한 역할을 수행하고 있다. 이 논문은 탈북청소년들의 신변보호 지원체계 및 문제점 분석을 통해 신변보호경찰관의 맞춤형 배치와 의식재고, 업무의 명확화 및 역량강화 방안을 비롯하여 범죄 예방대책 등을 제언하였다. 이러한 신변보호 개선방안들은 관계당국의 적극적인 실현 의지와 정부의 제도적인 뒷받침은 물론 국민들이 다 함께할 때 가능하다. 그러할 때만이 탈북청소년들이 건전한 국민으로 성장하여 향후 통일 과정에서 야기될 수 있는 정치적ㆍ사회적ㆍ문화적 갈등 해소와 사회적 혼란을 예방할 수 있는 인적 자원인 치안활동의 매개자로 성장할 수 있을 것이다. Recently, there have been an influx of North Korean refugees entering into South Korea, leading to changes in the population among the North Korean refugees. There were more male refugees than female in the past between the ages of the 20’s and 30’s, but the ratio of females, adolescences, and elders have increased in recent years. North Korean refugees who have entered into South Korea have suffered severely from post-traumatic stress disorder caused by the physical and psychological shock that occurred during the escape from North Korea, and making it difficult for them to settle in South Korea society. In addition they suffer from depression and anxiety due to social discrimination and ignorance during the period of adaptation. One of the reasons of social deviation among young North Korean refugees after settlement is a failure of understanding domestic circumstances. Solving a settlement problem of those young North Korean refugees in South Korea is not simply a solution of the current problem but is also a way to prevent future problems by integrating numerous young North Koreans after the unification of Korea. This is a one indicator for the success of social unification between North and South Korea. Security police has a direct effect in the success of resettlement and has an important role to protect and to assist in the resettlement of young North Korean refugees. This study analyzes the current status of adaptation among young North Korean Refugees in South Korea and the protection problem from security police. Furthermore, this article suggests improved protective roles and services of the police and the systemization of bodyguard services and protection from the arrival of young North Korean refugees. This study begins with an introduction in the first chapter, followed by a theoretical background in the second chapter, current status and problems among young North Korean refugees in the third chapter, an improvement of protection for young North Korean refugees in the fourth chapter, and a conclusion in the final chapter.
