Objectives : The purpose of the current study was to evaluate subject quality of life in depressed parents of boys with Duchenne/Becker muscular dystrophy (DMB/ BMD). In addition, a specific relationship between subject quality of life and the severity of depressive symptom was explored. Methods : The participants were 15 depressed parents who had moderate to severe depressive symptoms and 35 nondepressed parents of boys with DMD/BMD. All participants completed the World Health Organization Quality Of Life Scale, Brief Version and the Beck Depression Inventory. Other instruments included the Family Relationship Scale and the Child Behavior Checklist. Results : Among various model predictors, only higher score on the Beck Depression Inventory predicted lower scores on all domains of the World Health Organization Quality Of Life Scale, Brief Version. In addition, depressed parents had significantly lower scores on all domains of the World Health Organization Quality Of Life Scale, Brief Version including physical health, psychological health, social relationships, and environment, relative to non-depressed parents. Conclusion : Findings of the current study suggest that all domains of subjective quality of life may be influenced by depressive symptoms in parents of boys with DMD/BMD.

Purpose: Recently as couples have only one or two children, they concern about their children's optimal health. Furthermore, as the basic principles of Korean traditional prenatal education (Taegyo) are supported by scientific evidence, and as increasing numbers of pregnant women are recognizing Taegyo refresh, the practice of Taegyo is growing. The purpose of this study was to identify the factors associated with the practice of Taegyo among pregnant Korean women. Methods: This was a cross-sectional, survey study of 228 pregnant women recruited at a health center in South Korea using a convenience sampling method. The instruments included the perception of Taegyo scale, the spouse's support scale, the self-confidence for infant care scale, and the practice of Taegyo scale. The data were analyzed using descriptive statistics and multiple regression analyses. Results: The results of the stepwise multiple regression analysis indicated that the following factors accounted for 26.5% of the variance in the practice of Taegyo: the perception of Taegyo, family income. Conclusion: Consequently, this result showed that the pregnant women were influenced by family income, spouses' support as requisite factors, and also they developed the level of self-confidence for infant care and the perception of Taegyo as self-care agency for the practice of Taegyo. The present study findings will add to the accumulated knowledge of health care professionals about the cultural factors involved in the practice of Taegyo and the traditional cultural beliefs and culture-specific health promoting behaviors of ethnic minority pregnant women to provide culturally competent care for them.

Public bicycle system (PBS) is a new emerging and popular mode of public transportation. PBS data can be adopted to analyze human movement patterns. Previous work usually focused on specific scales, and the relationships between different levels of hierarchies are ignored. In this paper, we introduce a multi-scale and interactive visual analytics system to investigate human cycling movement and PBS usage condition. The system supports level-of-detail explorative analysis of spatio-temporal characteristics in PBS. Visual views are designed from global, regional and microcosmic scales. For the regional scale, a bicycle network is constructed to model PBS data, and an flow-based community detection algorithm is applied on the bicycle network to determine station clusters. In contrast to the previous used Louvain algorithm, our method avoids producing super-communities and generates better results. We provide two cases to demonstrate how our system can help analysts explore the overall cycling condition in the city and spatio-temporal aggregation of stations.

This study surveyed the general characteristics and forest use characteristics of forest visitors, the healing power of natural environments and Perceived Restorativeness Scale (PRS) to find out whether humans can feel the healing effects of natural environments. The target area of this study was the natural environments of Bunseong Mountain in Gimhae, Gyeongsangnam-do, Korea. A total of 50 questionnaires were analyzed. Female visitors and those aged between 40s to 60s accounted for 62% and over 70% respectively. All the surveyed respondents answered 'yes' to the question about the healing effects of Bunseong Mountain and natural environments, and 84% of them answered that they can get 'psychological and physical healing' in Bunseong Mountain. Many respondents chose oxygen, sunlight, and landscape as a healing factor. To the questions about the specific form or conditions of the natural environments that have the healing effects, those who answered 'forest' was the highest (72%), and they described thickness of forests, gentle slope and clean air as their conditions. The average score of the Perceived Restorativeness Scale (PRS) using a 7-point Likert scale was 5.14. The results of this study indicate that respondents perceive Bunseong Mountain as a restorative environment and think that they can enjoy the healing effects of Bunseong Mountain and natural environments.

The purpose of this study was to validate the Sasang Digestive function Inventory (SDFI) and Sasang Personality Questionnaire (SPQ) which measures the pathophysiolgoical symptoms and temperament of each Sasang types. The SDFI, SPQ along with Questionnaire for Sasang Constitution Classification II (QSCCII) were measured with 191 College students. The correlation coefficient was measured with Pearson correlation between SDFI and SPQ. The SDFI and SPQ subscale score of each Sasang constitution groups based on QSCCII were compared using analysis of variance and profile analysis. The SDFI and SPQ total score of So-Eum Sasang type were significantly (p<0.001) different compared to those of Tae-Eum and So-Yang type, respectively. The SDFI and SPQ profile of each Sasang type group was significantly (p<0.001) different each other in profile analysis. There were no significant correlation (r=.126, p>0.05) between SDFI and SPQ total score, however the SDFI-Digestion scale showed significant correlation with SPQ subscales. We found that the SDFI and SPQ can measure the Sasang type-specific pathophysiological symptoms and temperaments, and it would be useful for the clinical application and interdisciplinary research when combined together.

This study was conducted to investigated the removal efficiency of BOD and nutrient for the treatment of low strength municipal wastewater by a biological nutrient removal system. In this experiment, the effect of operating parameter including HRT of 7.0hr, BOD/TN ratios of 2.62~4.08, internal recycle of 50~300%, and return sludge of 50~100%, were studied during winter season. Efficiencies of organic matter and T-P removal and denitrification were not significantly affected by the change of temperature in winter season. However, the specific nitrification rate and nitrification efficiency decreased at low temperature. Besides, denitrification efficiencies increased with increasing BOD/TN ratios. It was also found that the internal recycle and return sludge ratio below 50% is required for the effective denitrification of low strength municipal wastewater. With operating mode 4 of the optimum, the effluent BOD, T-N and T-P concentration were obtained to average 5.8, 14.6, and 0.84 mg/L, respectively. The temperature-activity coefficient (${\theta}$) of specific nitrification rate, specific denitrification rate and specific phosphorus uptake rate were obtained 1.044, 1.017, 1.028, respectively.

In the present work, a pair of primers specific to Tomato yellow leaf curl virus (TYLCV) was designed to allow specific amplification of DNA fragments from any TYLCV isolates using an extensive alignment of the complete genome sequences of TYLCV isolates deposited in the GenBank database. A pair of primers which allows the specific amplification of tomato ${\beta}$-tubulin gene was also analyzed as an internal PCR control. A duplex PCR method with the developed primer sets showed that TYLCV could be directly detected from the leaf crude sap of infected tomato plants. In addition, our developed duplex PCR method could determine PCR errors for TYLCV diagnosis, suggesting that this duplex PCR method with the primer sets is a good tool for specific and sensitive TYLCV diagnosis. The developed duplex PCR method was further verified from tomato samples collected from some farms in Korea, suggesting that this developed PCR method is a simple and reliable tool for rapid and large-scale TYLCV detections in tomato plants.

Fluoride can be easily found in semiconductor and display industry. However, there is a lack of research for its effects on the related wastewater treatment. The objective of this study is to evaluate the microbial inhibitory effect by fluoride injection. The research entailed the assessment of removal efficiency of $TCOD_{Cr}$ according to the fluoride concentration and also the Specific Oxygen Uptake Rate (SOUR) was measured. The laboratory scale reactor was prepared and operated with the fluoride concentrations of 0, 10, 50, 100, and 200 mg/L based on concentrations frequently occurring in the wastewater. The results from this study showed that, as the fluoride concentration increase, the Specific Substrate Utilization Rate (SSUR) tend to decrease as expected. Also, the increase in fluoride concentrations resulted in the decrease in SOUR. It is determined that fluoride injection affects the microbial activity. Especially, The addition of above 200 mg/L fluoride into reactor caused rapidly decreased SSUR and SOUR due to the inhibitory effects of fluoride.

This paper presents a novel approach to face detection by localizing faces as the goal-specific saliencies in a scene, using the framework of selective visual attention of a human with a particular goal in mind. The proposed approach aims at achieving human-like robustness as well as efficiency in face detection under large scene variations. The key is to establish how the specific knowledge relevant to the goal interacts with the bottom-up process of external visual stimuli for saliency detection. We propose a direct incorporation of the goal-related knowledge into the specification and/or modification of the internal process of a general bottom-up saliency detection framework. More specifically, prior knowledge of the human face, such as its size, skin color, and shape, is directly set to the window size and color signature for computing the center of difference, as well as to modify the importance weight, as a means of transforming into a goal-specific saliency detection. The experimental evaluation shows that the proposed method reaches a detection rate of 93.4% with a false positive rate of 7.1%, indicating the robustness against a wide variation of scale and rotation.
