This study investigates coping strategies of overweight or underweight males in Korea. For this purpose, the authors identify types of stress related to weight management. A qualitative method was utilized to collect the data related to successful weight management experiences of males aged 20-37 years. Data were analyzed based on a motivation theory of coping, which suggests coping strategy elements. The results of this study identified the stress related to weight: dissatisfaction with appearance, others' disapproval of appearance, health problems, weaker athletic ability, negative self-perception, passiveness about appearance, lower romantic attractiveness, others' disapproval of lower romantic attractiveness, weakened task execution capability, and negative stereo-types about task execution capability. In addition, six coping strategies were suggested: improved appearance, improved physical function, improved positive self-perception, more choices to improve appearance, enhanced romantic relationship, and enhanced job performance. This study shows that weight problems in modern society are diverse and complex. Therefore a man who has abnormal weight needs to clarify his stress first and then proposes strategies that are appropriate for each type of stress.

The weight estimation of floating offshore structures such as FPSO, TLP, semi-Submersibles, Floating Offshore Wind Turbines etc. in the preliminary design, is one of important measures of both construction cost and basic performance. Through both literature investigation and internet search, the weight data of floating offshore structures such as FPSO and TLP was collected. In this study, the weight estimation model was suggested for FPSO. The weight estimation model using non-linear regression analysis was established by fixing independent variables based on this data and the multiple regression analysis was introduced into the weight estimation model. Its reliability was within 4% of error rate.

A phenomenological study is conducted to investigate the experience of mothers with very low birth weight. Sample of 8 mothers participate. Seven theme clusters emerge when the formulated meanings were organized into categories. The participants are 8 mothers who gave birth in the general hospital located in Kyunggi-Province and still live there. The data are collected from the intensive interviews on the experience of mothers whose baby is very low birth weight infant. Data collection is through in depth personal interviews two or three times with each mother. On the basis of the meanings of the experience of mothers with very low birth weight infant, the seven essential themes have been obtained Theme 1:Being surprised and perplexed due to the unexpected sudden delivery Theme 2:Experiencing emotional pain such as anxiety, sorrow, fear, confusion and self-blaming caused by a small and feeble baby. Theme 3: Pouring all their time and efforts into the baby under the acute tension Theme 4:Undergoing intolerable difficulties in confronting reality `Theme 5:Raising the special infant into an normal one by themselves Theme 6: Being on the vigilance for their baby even though they can be relieved Theme 7:Finding out a reward for the difficulties they have experienced The results obtained in this study will enable us to comprehensively understand the experience by mothers whose baby is very low birth weight infant and furthermore to provide a new insight which helps baby.

In this study, we studied the effect of onion on hyperlipidemia in terms of factors, such as body weight, liver weight, kidney weight, heart weight, blood glucose, total cholesterol, triglycerides, HDL-cholesterol, and LDL-cholesterol. The hyperlipidemia supplement was significantly effective on the liver weight, kidney weight, blood glucose, total cholesterol, triglycerides, and LDL-cholesterol with the fixed effect model. However, the liver weight, blood glucose, total cholesterol, and triglycerides were significantly decreased with the random effect model on the heterogeneous factors selected by Galbraith plot. The existence of publication bias was checked by using a funnel plot.

Purpose: The purpose of this study was to investigate the factors related to the academic burden on weight loss efforts among adolescents aged 12-18 in Korea. Methods: This study analyzed 29,069 obese adolescents (10.8%) using raw data of the 9th~12th the Korea Youth Risk Behavior Web-based Survey collected from 2013 to 2016. The data was analyzed using descriptive statistics, Chi-square and multivariate logistic regression. Results: Weight control efforts were significantly higher among girls, middle school students, those who are participating in nutrition education, and individuals with perceived fatness or perceived stress. Additionally, a long sitting time and high academic performance were found to be variables affecting the weight control efforts of adolescents. Conclusion: Obese adolescents in Korea spent a lot of time in their studies due to their academic burdens and this caused a lack of time to adjust their weight. Therefore, it is needed to establish a policy by considering these social and cultural factors for obese adolescents in Korea.

Purpose: This study examined the effects of the symmetrical scapular alignment on the weight bearing of hemiplegic patients in the standing position. Methods: PALM (PALpation Meter) test and Gaitview AFA-50 were used to measure the skeletal alignment of the scapula and the weight bearing loaded on the affected and unaffected sides before and after training. The data was analyzed using a paired t-test on the SPSS 12.0 program for descriptive statistics. A p value <0.05 was considered significant. Results: The mean difference in the scapular alignments on sup. & mid. & inf. area in the hemiplegic side before and after training was $0.93\pm0.50cm$ and $0.58\pm0.43cm$, respectively. There was a significant decrease after training rather than that before (p<0.05). The mean weight bearing on the foot area in the hemiplegic patients before and after training was $9.12\pm5.51N/cm^2$ and $4.36\pm4.11N/cm^2$, respectively,. There was a significant decrease after training rather than that before (p<0.05). The scapuar alignments and weight bearing data on the standing position were grouped around the average (to central point) in the distribution graph. Conclusion: These findings suggest that the symmetrical scapular alignment can serve as an effective means of improving the weight bearing ability of hemiplegic patients.

The purpose of this study is to clarify that neonatal massage is a nursing intervention which is desirable to LBW by making nurses provide such massage service to LBW hospitalized at NICU and confirming effects of the service on weight gain, vital signs and stress hormones(cortisol, norepinephrine, epinephrine). The data were collected from Dec. 14, 1998 to Oct. 4, 1999. The subjects were 28 LBW infants. The data were analyzed with the SAS program with T-test, Chi-square test and ANOVA. 1. The Experimental group that received neonatal massage showed a higher daily gain of weight than the comparative group. Weight gain for 10 days and weight gain of seven days after the massage were also higher in the former group than in the latter, indicating that there are statistically significant differences between the two groups.

Recently, eigenvoice approach has been widely used for rapid speaker adaptation. However, even in the eigenvoice approach, Performance improvement using very small amount of adaptation data is relatively small in comparison with that using somewhat large adaptation data because the reliable estimation of weights of eigenvoice is difficult. In this paper, we propose a rapid speaker adaptation method based on eigenvoice using the weight distribution characteristics to improve the performance on a small adaptation data. In the Experimental results on vocabulary-independent word recognition task (using PBW 452 database), the weight threshold method alleviates the problem of relatively low performance for a tiny small adaptation data. When single adaptation word is used, word error rate is reduced about 9-18% by the weight threshold method.

In this study, the weight of evidence(WofE) technique based on GIS was applied to spatially estimate the groundwater yield characteristics at the Pocheon area In Gyunggi-do. The groundwater preservation depends on many hydro-geologic factors that include hydrologic data, land-use data, topographic data, geological map and other natural materials collected at the site, even with man-made things. All these data can be digitally processed and managed by GIS database. In the applied technique of WofE, the prior probabilities were estimated as the factors that affect the yield on lineament, geology, drainage pattern or river system density, landuse and soil. We calculated the value of the weight values, W+ and W-, of each factor and estimated the contrast value of it. Results by the groundwater yield characteristic computation using this scheme were presented feasibility map in the form of the posterior probability to the consideration of in-situ samples. It is concluded that this technique is regarded as one of the effective techniques for the feasibility mapping related to the estimation of groundwater-bearing potential zones and its spatial pattern.

We propose a probabilistic fish growth model for smart aquaculture systems equipped with IoT sensors that monitor the ecological environment. As IoT sensors permeate into smart aquaculture systems, environmental data such as oxygen level and temperature are collected frequently and automatically. However, there still exists data on fish weight, tank allocation, and other factors that are collected less frequently and manually by human workers due to technological limitations. Unlike sensor data, human-collected data are hard to obtain and are prone to poor quality due to missing data and reading errors. In a situation where different types of data are mixed, it becomes challenging to develop an effective fish growth model. This study explores the unique characteristics of such a combined environmental and weight dataset. To address these characteristics, we develop a preprocessing method and a probabilistic fish growth model using mixed data sampling (MIDAS) and overlapping mixtures of Gaussian processes (OMGP). We modify the OMGP to be applicable to prediction by setting a proper prior distribution that utilizes the characteristic that the ratio of fish groups does not significantly change as they grow. We conduct a numerical study using the eel dataset collected from a real smart aquaculture system, which reveals the promising performance of our model.
