The objective of this study was to access the effect of climate and soil factors on alfalfa dry matter yield (DMY) by the contribution through constructing the yield prediction model in a general linear model considering climate and soil physical variables. The processes of constructing the yield prediction model for alfalfa was performed in sequence of data collection of alfalfa yield, meteorological and soil, preparation, statistical analysis, and model construction. The alfalfa yield prediction model used a multiple regression analysis to select the climate variables which are quantitative data and a general linear model considering the selected climate variables and soil physical variables which are qualitative data. As a result, the growth degree days(GDD) and growing days(GD), and the clay content(CC) were selected as the climate and soil physical variables that affect alfalfa DMY, respectively. The contributions of climate and soil factors affecting alfalfa DMY were 32% (GDD, 21%, GD 11%) and 63%, respectively. Therefore, this study indicates that the soil factor more contributes to alfalfa DMY than climate factor. However, for examming the correct contribution, the factors such as other climate and soil factors, and the cultivation technology factors which were not treated in this study should be considered as a factor in the model for future study.

Sorghum×sudangrass hybrid (Sorghum bicolor (L.) Moench, SSH) is one of the most important summer forage crop and it is widely used for silage in Korea. Agriculture is highly dependent on the climate condition and experiencing significant loss of productivity due to climate change. This study was conducted to investigate the correlation analysis between productivity of forage SSH and climatic factors in Central Northern region of South Korea for 3 years (2017 to 2019). Plant height and dry matter yield of SSH were significantly higher in Gyeonggi-do than Ganwon-do. The productivity of SSH is more closely related with temperature than other climatic factors. Maximum temperature and Growing degree days in May and June showed a positive correlation. However, correlation between production of SSH and precipitation was not clear in this study, but rainy days showed a negative correlation (0.42). In conclusion, temperature is most important climatic factor to the maintenance of plant yield.

With the continuous deterioration and rebound of Novel Corona Virus Disease worldwide, the impact on all areas of society can not be underestimated. In particular, the normalization of the pandemic has also had a profound impact on the development and adaptation of adolescents from overseas working families. There are a large number of special social groups, adolescents from overseas working families in Yanbian, China. Affected by severe pandemic normalization, these adolescents have been separated from their parents for a long time, suffering from troubles and many other problems. School adaptation is an important measure of adolescents' social adaptability. In order to explore the influencing factors of school adaptability of Chinese-Korean adolescents from overseas working families, this study did a questionnaire survey on them through the method of cluster sampling. A total of 602 valid questionnaires were collected. Among them, there are 289 adolescents from overseas working families, accounting for about 48%. The correlation and multiple regression analysis were carried out with SPSS 24.0. The results show that: 1) There is a significant correlation between the main factors; 2) Self-esteem and depression in personal factors, parental attachment in family factors, and teacher-student relationship and school performance in school factors have a significant impact on adolescents‘ school adaptability. Finally, this paper puts forward a system to strengthen the school adaptability of adolescents from Chinese-Korean overseas working families, as well as some specific intervention measures.

Sodium intake has been associated with the health-related quality of life (HRQoL). This study examined the demographic factors related to HRQoL and whether there is an association between sodium intake and HRQoL in adults residing in rural areas. A total of 1,980 adults (aged ≥20 years) were selected from a cross-sectional study conducted between December 2013 and February 2014 in Gyeongju, South Korea. The sodium intake and HRQoL were measured using a validated food frequency questionnaire and the EuroQol Five-Dimension (EQ-5D) (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), respectively. The education levels (<5 years) were inversely associated with all five dimensions of HRQoL. Men had better EQ-5D scores for each of the five components examined. Adults living with spouses had better scores related to usual activities and anxiety/depression, whereas widowers had decreased scores of mobility and self-care. Unlike older adults aged 70-79 years, adults aged <60 years were more likely to have greater scores related to mobility, usual activities, and pain/discomfort. The income levels were also inversely related to the scores for self-care, usual activities, pain/discomfort, and anxiety/depression. Sodium intake was positively associated with the HRQoL related to self-care, usual activities, and pain/discomfort, but it was negatively associated with anxiety/depression. In conclusion, these findings suggest that the demographic factors and sodium intake were independently associated with HRQoL. The results highlight the need to provide tailored, targeted policies and interventions that consider personal characteristics and dietary intake to improve the overall HRQoL in adults residing in rural areas.

This study investigated the factors affecting restrained and emotional eating according to the BMI of college women in Seoul. Based on their weight, 514 college women were divided into 3 groups. General demographics, nutrient consumption, eating habits and DEBQ were subsequently evaluated. Multiple regression analysis was performed to determine the factors responsible for restrained and emotional eating in each group. Percentage of the overweight or obese group having negative emotions, such as frequency of overeating (p<0.05), habitual eating, regret, and guilt after overeating, was higher as compared to the other groups (p<0.001). Considering factors that affect restrained eating, negative emotion after overeating had a positive correlation in the underweight group (β=0.481, p<0.001). In the normalweight group, the BMI (β=0.201, p<0.001), total food intake (β=0.241, p=0.002), and negative emotion after overeating (β=0.284, p<0.001) positively affected restrained eating. In the underweight group, habitual eating (β=0.292, p=0.002) and negative emotions after overeating (β=0.233, p=0.012) were determined to affect emotional eating. Moreover, habitual eating (β=0.290, p<0.001) and negative emotions after overeating (β=0.172, p=0.004) were observed to influence emotional eating in the normal weight group. In the overweight and obese groups, habitual eating was determined to affect emotional eating (β=0.410, p<0.001). Taken together, these results provide a basis for creating a weight control program for young women having undesirable eating behaviors, such as restrained and emotional eating.

This study compared the lifestyle patterns, dietary patterns, and health care practices of Korean middle-aged people by household type, and ultimately analyzed their relationship with different risk factors for the prevalence and severity of metabolic syndrome. We analyzed the data from 4,755 subjects who were from 40 to 64 years old, and gathered our sample from participants of the Korea National Health and Nutrition Examination Survey from 2013 to 2015. Our results showed that single-person households had lower economic income levels, lower subjective health statuses, and higher levels of food instability than households with two or more individuals. The incidence of metabolic syndrome was 1.64 times higher in single-person households than in households with two or more individuals. After adjusting for potential confounding factors (sex, age, education, household income, smoking status, health status, and dietary factors), single-person households showed 1.75 times higher hypertriglyceridemia ORs than non-single-person households. In the conclusion of our study, we suggest that middle-aged people in single-person households may be at greater risk for metabolic syndrome and hypertriglyceridemia.

본 연구의 목적은 모발 성장인자 관련 논문의 고찰을 통해 성장인자가 탈모에 적용되었을 때 모발의 시너지 효과를 연구하여 뷰티산업 종사자들이 전문적이고 경쟁력 있는 제품 선택의 폭을 넓힐 수 있으며 그로 인해 틈새 시장인 점판 시장의 활성화로 뷰티산업의 발전에 기여하고자 하였다. 성장 인자는 인체가 출생 시 가지고 태어나는 세포분열 활성화인자로 기능이 떨어진 세포를 자극하여 모발 성장과 모유두 세포의 세포 분열을 촉진시키며 모발 성장기를 연장시킨다. 모낭에서 발현되는 것으로 보고된 성장 인자는 섬유아세포 성장인자(bFGF, basic Fibroblast GF), 혈관내피세포 성장인자(VEGF, Vascular endothelial Growth Factor), 인슐린 유사 성장인자(IGF-1, Insulinlike Growth Factor), Noggin(모낭자극성장인자), 줄기세포증식인자 (SCF, Stem Cell Factor), 케라틴형성세포 성장인자(KGF ,keratinocyte growth factor), 간세포성장인자 (HGF, hepatocyte growth factor) 등이 있다. 이들 성장인자들은 각각 모낭과 모발의 형성을 촉진하며 모낭의 성장을 조절하고 모발의 성장기 유지에 기여하며 정상적인 성장 주기로 컨트롤 한다. IGF-1과 GH를 같이 투여하면 시너지 효과를 얻어 피부 파필라 주위의 매트릭스 세포와 결합 조직 피복(CTS)의 두께가 증가함을 알 수 있다. 프로시니아딘(포도씨 추출물)과 산사열수 추출물은 모발 성장과 모유두세포의 성장인자 유전자 발현에 유의미하다. 황칠나무 잎 추출물의 적용 시도 모유두 세포의 성장인자 유전자 발현에 유의미한 효과가 있다. 모발이 성장함에 따라 IGF-1의 발현 은 증가되고 TGF-β1의 발현은 감소되어 모유두 세포의 퇴행과 감소를 지연시켜 주는 역할을 하여 성장인자가 남성형 탈모를 지연시켜 줄 수 있다고 사료된다. 본 논문은 좀 더 편리하고 효과가 증대되는 대중적인 두피.모발관리의 한 방법인 샴푸, 트리트먼트 등의 제품을 사용하여 다양하고 전문적인 제품에 대한 긍정적인 인식과 대안을 제시 하고자 하였으며 추후 더 많은 연구를 통하여 미흡한 점이 보완되기를 바란다 .

PURPOSES : Pavement growth (PG) is a phenomenon whereby the overall length of a concrete pavement increases. The increase in length induces an axial compressive force in the concrete pavement slab, resulting in blow-up and damage of adjacent structures, such as a bridge. PG is influenced by several interacting factors, including climatic conditions, pavement materials, joint systems, incompressible particles (IP) infiltrating the joints or cracks in the slab, and an expansion caused by reactive aggregates in the concrete. However, it is difficult to predict PG and blow-up due to various complicated factors. Therefore, in this study, the pavement growth and blow-up analysis (PGBA) package program was developed to predict the PG and blow-up potential. The PGBA can consider the pavement configuration, expansion joint (EJ) configuration, climatic conditions, and design reliability. To evaluate the effects of influencing factors — such as climatic data, EJ configuration, pavement structures and materials, and design reliability — on PG and occurrence time of blow-up, a numerical example was demonstrated and a sensitivity analysis was performed. METHODS : To predict the PG, the concrete temperature was calculated using an appropriate analytical model. The trigger temperature for pavement growth(TTPG) was predicted using a statistical equation that considers pavement age, joint spacing, and precipitation. An analytical solution for estimating the concrete slab movement was performed. Through the calculated TTPG and the amount of PG, the service life of the EJ (width of EJ) can be predicted compared to the allowable width. In addition, by using analytical and finite elements, the safe temperature(Tsafe) for preventing blow-up occurrence was calculated. The blow-up occurrence was assumed to occur when the variation between the concrete temperature and TTPG was larger than Tsafe. RESULTS :As a result of the sensitivity analysis of maximum temperature and precipitation, the temperature and precipitation increase and the EJ service life and possibility of blow-up decrease. Sensitivity analysis was performed on the thermal expansion coefficient, pavement thickness, base layer type, concrete elastic modulus, and joint rotational stiffness in the concrete pavement structure and properties. In the PGBA program, the coefficient of thermal expansion and the type of base layer significantly affect the EJ life, as do the possibility of blowup and the elastic modulus. The joint rotational stiffness and pavement thickness had little effect on the EJ life but were found to affect the possible timing of blow-up. As a result of the PGBA sensitivity analysis of the width and spacing, which are the specifications of the EJ, the life of the EJ and the possibility of blow-up increased as the joint width increased; however, the EJ life and blow-up increased as the EJ interval reached a certain value. It was found that the possibility of a blow-up occurrence decreased. The results for the PGBA program in extreme weather conditions, the life span of EJs, and the possibility of blow-up in normal climates were reduced by over 50 %. CONCLUSIONS : As a result of PGBA sensitivity analysis, it was found that the substrate type, thermal expansion coefficient, precipitation, and alkali-silica reaction had the greatest influence on pavement expansion and blow-up.

Autophagy is a cell survival mechanism that works for the survival of cells under various physiological and pathological conditions. ATG5 is a key protein in the process of autophagy propagation and is involved in tumor development and progression. Chemotherapeutic agents targeting ATG5 enhance the host's immune response in various human cancers and intensify the effectiveness of chemotherapy. However, the physiological role of ATG5 protein in oral squamous cell carcinoma (OSCC) has not been fully recognized. The purpose of this study was to examine the correlation between clinico-pathological factors of OSCC patients and ATG5 immunoexpression through immunohistochemistry (IHC) in the tissues of OSCC patients treated at our hospital, and to analyze the regarding influences and their mechanisms. The authors analyzed 20 OSCC patients from National University Dental Hospital, at Pusan National University from January 2002 to December 2007, which were eligible for the study. Data were obtained by reviewing the medical records of the OSCC patients, and ATG5 immunoexpression was obtained using IHC staining in the tissue samples of the OSCC patients. In the tissue sample of OSCC patients, the immunoexpression of ATG5 elevated, in comparison to the normal oral mucosa, and there was a significant correlation with Drinking, Pathological Stage. In regards to Cox regression analysis, Clinical stage, Tumor size, Histopathologic grade, Cervical nodal metastasis, Loco-regional recurrence, and ATG5 expression have statistically significant correlations. These results imply that the changes in the expression of ATG5 proteins in OSCC can be a prominent factor in the OSCC progression and the prognosis of OSCC patients.

The seismic deformation method is conventionally used as a seismic design for a multi-utility tunnel in Korea. In the seismic deformation method, the soil ground’s natural period is one of the most critical factors for calculating the ground displacement using cosine functions. Correction factors for the natural period and shear wave velocity have been used to consider the non-linearity of dynamic soil properties. However, the correction factors have been issued because the correction factors have not been sufficiently studied to consider Korea’s regional conditions. This paper aims to evaluate the natural periods for the seismic deformation method considering Korea’s ground conditions. Ground response analysis was performed using seven real earthquake records on twelve sites with different soil conditions where actual multi-utility tunnels are installed. As a result, natural periods of the sites were analyzed and new correction factors were proposed according to seismic performance and Korea’s regional conditions.

This study used a food-frequency questionnaire to estimate fruit consumption by sex, age, and type of fruit to analyze the association between fruit type and metabolic factors. Using food-frequency-questionnaire data from 3,091 adults aged 19~64 years (1,184 men and 1,907 women) in the 2016 Korea National Health and Nutrition Examination Survey, this study analyzed weekly fruit consumption and the consumption frequency of strawberry, oriental melon, watermelon, peach, grape, apple, pear, persimmon/ dried persimmon, tangerine, banana, orange, and kiwi by sex and age groups. Apple was the most-consumed fruit (459.45 g/wk), followed by pear (165.80 g/wk), watermelon (124.80 g/wk), and banana (115.32 g/wk). After adjustment for confounding factors, ED: Please give examples. in the women who ate more than the median consumption of apple, the prevalence of hyperglycemia was 27.4% (OR: 0.726, 95% CI: 0.539~0.979) (p=0.0362), and of high triglycerides, 25.7% (OR: 0.743, 95% CI: 0.564~0.978) (p=0.0340). These rates were lower than those of women who ate less than the median consumption of apple. The results of this study suggest that apple consumption helps improve metabolic indicators in Korean adults.

기상현상관측은 기상청에서 다양한 방법(지상, 고층, 해양, 항공, 등)으로 관측되고 있다. 하지만, 인간생활에 많은 영향을 미치는 대기경계층 관측에는 한계가 있다. 특히, 존데 또는 항공기를 이용한 기상관측은 경제적인 측면에서 상당 한 비용이 필요하다. 따라서 본 연구의 목적은 기상드론을 이용하여 국지기상현상 중 해륙풍 연직분포에 대한 기상 인자들을 측정하고 분석하는 것이다. 해륙풍의 공간적 분포를 연구하기 위해 보성지역 표준기상관측소의 보성종합기상탑을 포함한 다른 세 지점(해안가, 산기슭, 산중턱)에 동일한 통합기상센서를 각 드론에 탑재하였다. 2018년 8월 4일 1100 LST부터 1800 LST까지 30분 간격으로 최대 400 m 고도까지 기온, 상대 습도, 풍향, 풍속, 기압의 연직 프로파일 관측이 수행되었다. 기온, 상대 습도, 기압에 대한 기상현상의 공간적 특성은 네 지점에서 보이지 않았다. 강한 일사량 시간 대에 중간지점(~100 m)에서 강한 바람(~8 m s−1 )이 관측되었고, 오후에는 풍향이 내륙지역의 상층부터 서풍으로 바뀌었다. 기상드론을 이용하여 관측한 하부 대기층의 분석결과는 보다 정확한 기상예보 향상에 도움이 될 것으로 기대된다.

Identifying the water circulation status is one of the indispensable processes for watershed management in an urban area. Recently, various water circulation models have been developed to simulate the water circulation, but it takes a lot of time and cost to make a water circulation model that could adapt the characteristics of the watershed. This paper aims to develop a water circulation state estimation model that could easily calculate the status of water circulation in an urban watershed by using multiple linear regression analysis. The study watershed is a watershed in Seoul that applied the impermeable area ratio in 1962 and 2000. And, It was divided into 73 watersheds in order to consider changes in water circulation status according to the urban characteristic factors. The input data of the SHER(Similar Hydrologic Element Response) model, a water circulation model, were used as data for the urban characteristic factors of each watershed. A total of seven factors were considered as urban characteristic factors. Those factors included annual precipitation, watershed area, average land-surface slope, impervious surface ratio, coefficient of saturated permeability, hydraulic gradient of groundwater surface, and length of contact line with downstream block. With significance probabilities (or p-values) of 0.05 and below, all five models showed significant results in estimating the water circulation status such as the surface runoff rate and the evapotranspiration rate. The model that was applied all seven urban characteristics factors, can calculate the most similar results such as the existing water circulation model. The water circulation estimation model developed in this study is not only useful to simply estimate the water circulation status of ungauged watersheds but can also provide data for parameter calibration and validation.
