Objectives: Dropout and weight regain are common problems in most obesity treatments. The purpose of this study was to review previously published study results of the predictive factors associated with dropout during weight loss treatment and weight loss maintenance after successful weight loss. Methods: Authors searched for the articles related to dropout and weight loss maintenance, published from 2007 to 2016 found on Pubmed, Scopus, RISS, and KISS. A total of 19 articles were finally selected. From the study results, unchangeable and changeable predictors were extracted, and these predictors were examined according to dropout and weight loss maintenance categories. Results: The unchangeable predictors of dropout were younger age, lower education level and female, whereas the changeable predictors of dropout were lower initial weight loss, symptoms of depression and body dissatisfaction. The strongest factor for predicting the dropout was initial weight loss. The unchangeable predictors of weight loss maintenance were old age, male and family history of obesity, whereas the changeable predictors of weight loss maintenance were regular exercise, dietary restraint, self-weighing and low depressive symptoms. Initial weight loss, depressive symptoms, body image, dietary restraint, physical activity, weight loss expectation and social support were considered to be dominant factors for weight loss treatments. Conclusions: Our review results suggest that unchangeable and changeable predictors of dropout and weight loss maintenance should be carefully examined during treatments of obesity.

This study explores the feasibility of granite waste aggregate (GWA) as a partial replacement of natural fine aggregate (NFA) in binary blend self-compacting concrete (SCC) prepared with fly ash. Total of nine SCC mixtures were prepared wherein one was Ordinary Portland cement (OPC) based control SCC mixture and remaining were fly ash based binary blend SCC mixtures which included the various percentages of GWA. Fresh properties tests such as slump flow, T₅₀₀, V-funnel, J-ring, L-box, U-box, segregation resistance, bleeding, fresh density, and loss of slump flow (with time) were conducted. Compressive strength and percentage of permeable voids were evaluated in the hardened state. All the SCC mixtures exhibited sufficient flowability, passing ability, and resistance to segregation. Besides, all the binary blend SCC mixtures exhibited lower fresh density and bleeding, and better residual slump (up to 50% of GWA) compared to the OPC based control SCC mixture. Binary blend SCC mixture incorporating up to 40% GWA provided higher compressive strength than binary blend control SCC mixture. The findings of this study encourage the utilization of GWA in the development of binary blend SCC mixtures with satisfactory workability characteristics as a replacement of NFA.

Purpose: The purpose of this study was to examine the effects of problem solving nursing counseling and walking exerciseon weight loss, cardiovascular risk factors, and self-efficacy of diabetic control among obese diabetic patients. The Polar heart rate monitor was used for walking exercise to utilize the Biofeedback mechanism. Method: Fifty nine diabetic patients were conveniently placed into experimental (n=35) and control groups (n=24). The experimental group participated inweekly nursing counseling for 12 weeks and was encouraged to do walking exercise using a Polar monitor. The control group remained in the same treatment as before. The data wascollected from November 2003 to August 2004 and analyzed using t-tests and ANCOVAs. Results: After 12 weeks, the participants in the experimental group reported significantly decreased body weight (p=.004) and total scores on the Parma scale (p=.00l). While the participants in the control group reported significantly increased levels of blood triglyceride (p=.046) and HDL (p=.018). Conclusion: Based on the findings, we concluded that problem focused nursing counseling with intensified walking exercise could reduce the risk of cardiovascular complications and body weight among obese diabetic patients. Future research to explore the long-term effects of nursing counseling on diabetic complications is warranted.

Purpose: The purpose of this study was to provide basic data for the development of weight control programs to maintain and promote healthy behavior in women college students by identifying their weight control behaviors and factors that influence these behaviors. Method: Data were collected from 300 women student participants and were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with the SPSS 18.0 program. Result: Weight control behavior showed a significant difference according to participants' gender role identity type. Weight control behaviors were correlated with self-efficacy, body image, objective BMI, and ideal BMI. Factors influencing weight control behavior were self-efficacy (${\beta}$= .449, $p$<.001), secret method for weight loss (${\beta}$= .181, $p$<.001), monthly allowance below 200,000 won (${\beta}$= .156, $p$= .006), weight control support from others (${\beta}$= .124, $p$= .013), eating breakfast (${\beta}$= .119, $p$= .015), and age (${\beta}$= .113, $p$= .023) with R-sq. value of 45.3%. Conclusion: The results of the study indicate that development of interventions for weight control behavior and health education for college women should reflect identified factors influencing weight control behavior and gender role identity.

The analysis and control algorithm of a new type unsymmetrical self-bearing step motor is presented. The motor actuator is used for both motor and bearing functionality without any redundant coil windings or redudant electromagnets for bearing functionality. Self bearing step motor layout and control current generation method for unsymmetrical position of electromagnets are described. This new current generation method without additional current for bearing functionality leads to minimize the power loss. As the result of the unbalance response approach, the constant torque is possible, even though the bearing functionality is added or not.

In our study, the PTFE nozzle ablation in the high-voltage self-blast type $SF_6$ gas circuit breaker was investigated. The test circuit breaker has the structure that the pin electrode is moving and the pressure reservoir volume and the dimension is almost same as commercial 145kv 40kA circuit breaker for similar result in real circuit breaker. The variation of current and arcing time was the range of $36kA_{rms}$(symmetry) - $40kA_{rms}$(asymmetry) and 10-16 ms. From the measured data the tendecy of the mass loss of the nozzle to current load and arc energy was estimated. In this process, the distance from the arc to nozzle(PTFE) surface, area which was exposed to arc and stroke contour was considered. These results will be used to enhance the accuracy of the computational fluid dynamics analysis in circuit breaker and estimate the residual life time of a circuit breaker.

The control algorithm of a new type self-bearing step motor is presented. The motor actuator is used for both motor and bearing functionality without any redundant coil windings or redundant electromagnets. The self$.$bearing step motor layout and its control method are described. A linearized farce-current-displacement relationship is derived. As the result of the unbalance response approach, the constant torque production is possible fur the supply current regulation algorithm. And even if the bearing functionality is added in the motor functionality, no additional current for bearing functionality is possible, and this leads to minimize the net power loss. Also, the unbalance response shows the independent bearing force and motor torque.

본 연구는 소상공인이 사업운영 시 경험했던 손실지각이 실패에 대한 두려움을 통해 재기에 어떤 영향을 미치는지를 확인하고자 폐업을 경험한 소상공인 413명을 대상으로 설문조사를 했다. 분석 결과는 다음과 같다. 첫째, 재무적자본, 시장경쟁력, 사회적자본의 지각된 손실이 클수록 실패에 대한 두려움은 컸다. 둘째, 실패두려움이 클수록 재창업 의지는 적었으나, 취업의지에는 영향을 미치지 못하였다. 셋째, 재무적자본, 시장경쟁력, 사회적 자본에 대한 지각된 손실이 실패두려움을 키우고, 이는 재창업 의지에도 부정적 영향을 미쳤다. 그러나 취업의지에 대해서는 시장경쟁력에 대한 손실지각만이 실패두려움을 통해서 취업의지를 강화했다. 이는 시장경쟁력으로 인해 폐업했다고 생각하면 창업보다는 취업을 선택할 가능성이 높다는 것을 시사한다. 넷째, 창업자기효능감이 높은 사람은 낮은 사람보다 손실지각이 실패두려움에 미치는 영향이 적었다. 즉, 창업효능감이 높은 사람은 재창업을 할 가능성이 높다고 볼 수 있다. 한편 연구결과, 사회적자본·재무적자본·시장경쟁력 손실지각 순으로 실패두려움에 영향을 미쳤는데, 소상공인들의 경우 창업시 상권내 경쟁과 위험도에 대한 이해부족으로 실패하는 경향이 큼에도 이에 대한 지각이 가장 낮았다. 또한 지인이나 친척 등 사회적 네트워크를 통해서 자금이나 영업활성화에 대한 지원을 받으려 하기 때문에 사회적 자본손실에 대한 지각이 실패에 대한 두려움에 미치는 영향이 가장 컸다고 추측된다. 본 연구는 이상의 결과를 바탕으로 정책실무 제언을 통하여 창업준비 시경쟁우위를 확보하기 위한 충분한 시장조사가 필요하며, 정교한 사업계획의 수립을 통해 재무적 손실을 줄일 수 있는 방안을 제시하고 있다.

A correction method of reflectivity in partial beam blockage (PBB) area is suggested, which is based on the combination of digital terrain information and self-consistency principle between polarimetric observation. First, the reflectivity was corrected by adding the radar energy loss estimated from beam blockage simulation using digital elevation model (DEM) and beam propagation geometry in standard atmosphere. The additional energy loss by unexpected obstacles and non-standard beam propagation was estimated by using the coefficient between accumulated reflectivity ($Z_H$) and differences of differential phase shift (${\Phi}_{DP}$) along radial direction. The proposed method was applied to operational S-band dual-polarization radar at Jindo and its performance was compared with those of simulation method and self-consistency method for six rainfall cases. When the accumulated reflectivity and increment of ${\Phi}_{DP}$ along radial direction are too small, the self-consistency method has failed to correct the reflectivity while the combined method has corrected the reflectivity bias reasonably. The correction based on beam simulation showed the underestimation. For evaluation of rainfall estimation, the FBs (FRMSEs) of simulation method and self-consistency principle were -0.32 (0.59) and -0.30 (0.57), respectively. The proposed method showed the lowest FB (-0.24) and FRMSE (0.50). The FB and FMSE were improved by about 18% and by 19% in comparison to those before correction (-0.42 and 0.70). We can conclude that the proposed method can improve the accuracy of rainfall estimation in PBB area.
