Purpose: The purpose of this study was to evaluate the effectiveness of three functional performance tests and one-legged hop test and to establish the reference data of the three functional performance tests of the active young Korean men. Materials and methods: We performed five tests on 40 normal subjects such as one-legged hop test (single hop, triple hop) and the three functional performance tests (carioca test, co-contraction test, shuttle run test). The mean age was 28.4 years. The mean score of Tegner activity scale was 6.2 and Lysholm score 98.2 Mean value and standard deviation were obtained. The correlation of age, height and weight with the results, the relationship between FPT and one-legged hop test and the mean difference between dominant and non-dominant limbs were statistically calculated. Results: All data obtained were normally distributed and there were no significant relationship between age, height and weight. The paired t-test of one legged hop test showed no statistical significance between dominant and non-dominant limbs. The results of one legged hop test had strong relationship with functional performance test. Conclusion; The three functional performance tests can be a useful functional test in ACL-insufficient athletes. Our results can be used as normal reference data of the normal active Korean men.

The study investigated the effect of food safety knowledge, food safety trust and the factors influencing organic food purchase intention in the 'new normal' of the COVID-19 pandemic. The study employed non-contrived and cross-sectional methods. The data was collected in Malaysia using convenience sampling. A total of 330 valid questionnaires were analyzed using Structural Equation Modelling (SEM) and PROCESS for hypothesis testing. The study revealed a significant relationship involving food safety knowledge on personal attitude, perceived social pressure, and perceived autonomy. Moreover, organic food purchase intention was found to be influenced by personal attitude, perceived social pressure, and perceived autonomy. Interestingly, trust in organic food safety moderated the relationship between perceived autonomy and organic food purchase intention. The study proved valuable for stakeholders and organic food producers to understand the 'new normal' COVID-19 market scenario for a sound understanding of the market and the sustainability of the organic food industry. A new research framework is proposed and validated, related to individual purchase decision in global health issues which is limited in current literature. Hence, the study contributed to a better comprehension of green consumerism mainly in the Asian market.

Modified cut-off sampling is widely used for highly skewed data. A serious drawback of modified cut-off sampling is the difficulty of adjustment of non-response in take-all stratum. Therefore, solutions of the problems of non-response in take-all stratum have been studied in various ways such as substitute of samples, imputation or re-weight method. In this paper, a new cut-off point based on minimizing MSE being used in exponential and power functions is suggested and it can be reduced the number of take-all stratum. We also investigate another cut-off point determination method with underlying distributions such as truncated log-normal and truncated gamma distributions. Finally we suggest the optimal cut-off point which has a minimum of take-all stratum size among suggested methods. Simulation studies are performed and Labor Survey data and simulated data are used for the case study.

Purpose: This study sought to investigate the relationship between smoking, drinking and the mental health of adolescents. Method: The study subjects included 1,092 randomly sampled third-year middle and high school students from N-City and the L-Kun area in Chonbuk Province. The data were collected using an anonymous questionnaire developed by the Ministry of Health and Welfare(2005). The data were analyzed using the SPSSWIN 15.0 Program. Result: The smoking rate in the adolescents was 10.1%, and the drinking rate was 43.2%. The stress recognition rate in normal daily life was 45.5%, the frequency of depressive symptoms was 33.2% and 40.0% of the subjects reported that they wanted to die at some point within the past year. The rate of stress recognition, depressive symptom experience, suicidal planning and attempt in smokers and drinkers was higher than that in non-smokers and non-drinkers (p<.05). Especially, the frequency of suicidal thoughts was higher in the drinkers than in the non-drinkers (p<.05). Conclusion: The smoking and drinking status of the adolescents was correlated with their mental health a sit relates to stress, depression and suicide. Therefore, an effective program for the prohibition of cigarette smoking and alcohol consumption is needed in order to prevent smoking and alcohol consumption in adolescents and improve their mental health status.

In this paper, we consider the cybersecurity issue of ship information system (SIS) from a new perspective which is called opacity. For a SIS, its confidential information (named as "secret") may be leaked through the working behaviors of each Distributed Control Unit (DCU) from an outside observer called an "intruder" which is able to determine ship's mission state by detecting the source of each data flow from the corresponding DCUs in SIS. Therefore we proposed a dual layer mechanism to enforce opacity by activating non-essential DCU during secret mission. This mechanism is calculated by two types of insertion functions: Safety-assured insertion function ($f_{IS}$) and Admissibility-assured insertion function ($f_{IA}$). Due to different objectives, $f_{IS}$ is designed to confuse intruder by constructing a non-secret behaviors from a unsafe one, and the division of $f_{IA}$ is to polish the modified output behaviors back to normal. We define the property of "$I_2$-Enforceability" that dual layer insertion functions has the ability to enforce opacity. By a given mission map of SIS and the marked secret missions, we propose an algorithm to select $f_{IS}$ and compute its matchable $f_{IA}$ and then the DCUs which should be activated to release non-essential data flow in each step is calculable.

Purpose: The purpose of this study was to investigate the relationship between obesity, body image perception, and weight control for obesity management in adult women. Methods: The subjects of this study were 3,617 women aged over 19 years, who participated in the Seventh Korea National Health and Nutrition Examination Survey 2016. Data were analyzed through complex sampling design data analysis. Results: Right body image perception according to obesity was apparent between 70.6-81.7% of women and 76.5% of women with abdominal obesity perceived that they were normal. Obese women performed more weight control than non-obese women. Women with only abdominal obesity performed less weight control than non-obese women, and 47.3% of them performed weight control. Women who perceived themselves as obese performed more weight control than women who perceived themselves as non-obese (odds ratio, 2.08; confidence interval, 1.69-2.57), but body mass index was not observed to be associated with weight control. Conclusions: Education on abdominal obesity should be provided to increase awareness about abdominal obesity and its effective management, especially in women with only abdominal obesity. In addition, interventions for right body type perception should be provided for proper weight control along with prevention and management of obesity.

Purpose: This study was conducted to investigate the combined effects of abdominal obesity and alcohol drinking on the risk of hypertension in Korean adults (aged ${\geq}30yrs$). Methods: Data of 13,885 subjects from the sixth Korea National Health and Nutrition Examination Survey were analyzed. The multiple logistic regression tests were used for the analysis, including potential covariates of the model. Results: Frequency of drinking, typical drinking quantity, and frequency of binge drinking had a positive relation to hypertension. The odds ratio of hypertension for risk drinkers with abdominal obesity was 4.81 compared to non-risk drinkers with normal waist circumstance, whereas the odds ratios of hypertension for risk drinkers with normal waist circumstance and non-risk drinkers with abdominal obesity were 1.58 and 2.37 respectively. Conclusion: Both abdominal obesity and alcohol drinking patterns were strong risk factors of hypertension in the Korean adults. Risk drinkers with abdominal obesity showed a marked high risk in hypertension compared to those with a single condition alone.
