There are many different views of the opinion that smoking decreased the HDL cholesterol. So this cross-sectional study was attempted to find the influence which smoking, alcohol and weight affect HDL cholesterol. They were two groups;smoking group(409 males) and nonsmoking group(213 males). And HDL cholesterol, triglyceride, and total cholesterol of smoking group were compaired to them of nonsmoking group. Also the variables of age, relative weight, and alcohol were compaired. The HDL cholesterol of nonsmoking group was 47.2$\pm$10.1 mg/dl and the HDL cholesterol of smoking group was 45.5$\pm$10.7mg/dl. So there were no statistical difference. As smoking was increased in amount, HDL cholesterol was decreased slightly. According as the alcohol intake increases, especially only the HDL cholesterol of the moderate alcohol intake(101-200gm/week) group was significantly increased(P<0.05). As relative weight increases, HDL cholesterol were significantly decreased(P=0.007). Smoking was not statistical difference of HDL cholesterol. Moderately alcohol intake group(101-200gm/week) were increased the HDL cholesterol(P<0.05). Only relative weight was statistically decreased the HDL cholesterol(P<0.01). Multiple regression results that relative weight and alcohol were significant variable of the level of HDL cholesterol.

The standard design methodology was suggested to construct wetland system for reducing non-point source pollution from Saemangeum reclaimed paddy land. To set for the design flow and concentrations, runoff and water quality survey were conducted during the irrigation period in 2008 at Gyehwa reclaimed paddy land located at near Saemangeum lake. It is rational that 1ha is the optimum constructed wetland size. To meet this size, the moderate drainage area of reclaimed paddy field was 50ha under the conditions that rainfall is 30mm, average runoff coefficient is 0.83, and runoff capture ratio is 0.6. At these condition, the runoff volume from 50ha was 10,520 $m^3/d$ including base flow during irrigation period. To select the optimum wetland system, several case studies were conducted by focusing on the tidal reclaimed land areas having wetland systems in Seokmun. Pond-Wetland system was selected as the standard model because of showing the highest reduction efficiency. Single variable regression equation were delivered to estimate effluent water concentrations from the designed wetland by using long-term monitoring data from the Seokmun experiment site. The effluent concentration from the designed wetland using these equation were showed moderately range.

Atmospheric correction of satellite measurements is a major step to estimate accurate surface reflectance of solar spectrum channels. In this study, Simplified Method for the Atmospheric Correction (SMAC) radiative transfer model used to retrieve surface reflectance from MODIS (MODerate resolution Imaging Spectrometer) top of atmosphere (TOA) reflectance. It is fast and simple atmospheric correction method, so it uses for work site operation in various satellite. This study attempts a test of accuracy of SMAC through a sensitivity test to detected error sources and to improve accuracy of surface reflectance using SMAC. The results of SMAC as compared with MODIS surface reflectance (MOD09) was represented that low accuracy ($R^2\;=\;0.6196$, Root Means Square Error (RMSE) = 0.00031, bias = - 0.0859). Thus sensitivity analysis of input parameters and coefficients was conducted to searching error sources. Among the input parameters, Aerosol Optical Depth (AOD) is the most influence input parameter. In order to modify AOD term in SMAC code, Stepwise multiple regression was performed with testing and remove variable in three stages with independent variables of AOD at 550nm, solar zenith angle, viewing zenith angle. Surface reflectance estimation by using Newly proposed AOD term in the study showed that improve accuracy ($R^2\;=\;0.827$, RMSE = 0.00672, bias = - 0.000762).

Nitric oxide (NO) has emerged as an important intracellular and intercellular messenger, controlling many physiological processes and participating in the fertilization process via the autocrine and paracrine mechanisms. This study investigated whether nitric oxide synthase (NOS) inhibitior (L-NAME) and L-arginine could regulate in vitro fertilization and early embryonic development in mice. Mouse epididymal spermatozoa, oocytes, and embryos were incubated in mediums of variable conditions with and without L-NAME or L-arginine (0.5, 1, 5 and 10mM). Fertilization rate and early embryonic development were significantly inhibited by treating sperms or oocytes with L-NAME (93.8% vs 66.3%,92.1% vs 60.3%), but not with L-arginine. In contrast, fertilization rate and early embryonic development were conspicuously reduced when L-NAME or L-arginine was added to the culture media for embryos. Early embryonic development was inhibited by microinjection of L-NAME into the fertilized embryosin a dose-dependent manner, but only by high concentrations of L-arginine. These results suggest that a moderate amount of NO production is essential for fertilization and early embryo development in mice.

Lymphangiomas are congenital malformations of the lymphatic system. Cervicofacial lymphangioma represents 75% of all lymphangiomas. Surgical excision has been the treatment of choice, however the reported results have been unsatisfactory. Various sclerosants have been tried to treat lymphangiomas, with variable results and considerable side effects. Herein we report the results of treatment using intralesional picibanil for lymphangioma. Between January 1996 and January 1998, 16 patients with lymphangiomas, 10 boys and 6 girls, were treated with intralesional picibanil injections. All cases were treated as a primary therapy. Eight lymphagiomas were located in the neck, and 2 in the cheek, 2 in the parotid, 2 in the trunk, 1 in the oropharynx, 1 in the thigh. Dose and method of intralesional injection was similar to that reported by Ogita in 1987. Complete regression was observed in 10 cases and marked regression(> 75% size decrease) in 2 cases and moderate regression(75%-25% size decrease) in 2 cases and poor regression(< 25% size decrease) in 2 cases. No serious side effect was observed except fever lasting for 2-3 days. Intralesional injection of picibanil for lymphangiomas represents a safe, easy and effective way of treatment with high success rate. Picibanil injection can be used as a primary therapy for lymphangiomas.

Objectives: This study was conducted to analyze the mediating effect of self-identity on the relationship between aggression and school life adaptation of early adolescents. Methods: This study used the 5th-year data of the Korean Children & Youth Panel Survey (KCYPS) including 159 middle school 2nd students from single-parent families. The data was analyzed with open source statistics program R 3.5.0 to determine whether self-identity had a mediating effect on school life adaptation as an independent variable. Results: A moderate correlation was found among aggression, self-identity, and school life adaptation. As a result of the Sobel test, self-identity of early adolescents demonstrated a significant mediating effect on the relationship between aggression and school life adaptation. Conclusions: Given the significant mediating factor of self-identity, the strategies for early adolescents to boost their overall school life adaptation should be considered through intervention programs that help to enhance their self-identity.

The primary purpose of this study is to identify determinants influencing Vietnamese consumers' purchase intention towards Japanese convenience goods. The research model consisting of six factors affecting the dependent variable is proposed based on the Theory of Consumption Values and Theory of Perceived Value of purchase. This study employs a survey method in a convenient sampling method to collect data of target respondents. Data consisting of 180 samples was collected and analyzed using the SMARPLS3 software. The measurement model is assessed to confirm the validity and reliability of the construct, then hypotheses testing is performed with Bootstrapping analysis. The results demonstrated that five factors affect Vietnamese consumers' purchase intention towards Japanese convenience goods, including the price of the product, quality of the product, functional value, emotional value, and conditional value. Major findings of this study suggest that the functional value that consumer perceives about Japanese convenience goods has the most significant relationship with their purchase intention, followed by the quality of the product and the price of the product. Besides, emotional value and conditional value have a moderate influence on consumers' purchase intention. Whereas the influence of the epistemic value of the product on consumers' purchase intention is insignificant in this presented study.

Purpose: The purpose of this study was to identify the moderating effect of interpersonal skills on the relationship between childhood emotional trauma and depression. Methods: From June to July, 2017, a convenience sample of 226 nursing students was recruited. Research data were collected through self-report questionnaires and analyzed using SPSS version 22.0. Results: 68.1% (154) respondents experienced emotional abuse, and 48.1% (110) emotional neglect in childhood emotional trauma. The average depression score was 10.76. There were 54.4% (123), 34.5% (78), 12.8% (29), and 7.1% (16) of respondents with mild, moderate, and severe depression, respectively. The average interpersonal skills score was 3.59. There was a significant correlation between childhood emotional trauma (emotional abuse, emotional neglect), interpersonal skills and depression. And the moderating effect of interpersonal skills on the relationship between childhood emotional neglect and depression was significant. Conclusion: Interpersonal skills play a role as a moderating variable influencing the relationship between emotional neglect of childhood emotional trauma and depression, and also reduce the effects of childhood emotional trauma on depression. When developing a depression prevention program for nursing college students, such programs should consider strategies to reduce the negative effects of childhood emotional trauma and to improve interpersonal skills.

This quantitative study aims to examine the effect of family ownership on company performance empirically. Specifically, this study examines the moderating effect of corporate governance on the relationship between family ownership and company performance which has never been explored in the previous studies. This study's main target population was all listed companies in the Indonesian Capital Market Directory (ICMD) for 2008-2018. The study used criteria, namely data completeness, to measure research variables and obtained 2996 data or firm-year observations. The research contingency model to test the proposed hypothesis was the General Moment Method (GMM). The study presents the results of data descriptions shows the average, median, maximum, minimum, and standard deviation values for each variable. The descriptive data shows that family ownership is common in Indonesia: 64% of 244 companies in the sample. The inferential analysis results using a multiple regression model test show that family ownership significantly reduces company performance. However, corporate governance proxied by the board of directors, managerial risk profile, and independent commissioners significantly moderate the relationship between family ownership and company performance. Besides, the managerial risk profile and independent commissioners strengthened while the board of commissioners' presence weakened the effect of family ownership on performance.
