This study aims to propose the improvement direction of spatial organization of orphanage facilities by reflecting the international trend of child welfare facilities including 'enhancement of habitability', 'opening to the local community' and 'multi-functionality' on the basis of ideas of 'right of housing' and 'normalization'. Orphanage facilities are evolving from 'facilities' to accommodate unfortunate children to the concept of the 'community-care', and the residential space is also rapidly shifting to 'cottage' type resembling a residential type of ordinary family so as to enhance the self-esteem and relationship. To suggest the future-oriented changeability of current orphanage facilities, the present study conducted a nationwide survey of child welfare facilities and four Visiting researches of cottage type orphanage with different locations to investigate the appropriateness of housing type, organization of common use space, mode of management and facilities criteria. The results of this study are following: 1) For enhancement of habitability it is suggested that cottage type with various plans in the form of ordinary housing is appropriate, that the number of children per cottage is six or so, and that the number of less than two or three children per room is recommended. At the same time the adjustment of facilities criteria, simplified or complex, is suggested to support a similar residence pattern to ordinary home. 2) Specialized programs must be introduced to establish a base of welfare-network for community children according to features of location and a complex management must be sought in the connection with neighboring public facilities. 3) To secure the residential environment and quality of life for children, the concept of a simple playground space by the current facilities criteria must be broken away to reinforce the network of various outdoor spaces closely connected with living space.

Embryonic stem (ES) cells can self-renew and differentiate to various cells depending on the culture condition. Although ES cells are a good model for cell type specification and can be useful for application in clinics in the future, studies on ES cells have many experimental restraints including low transfection efficiency and transgene expression. Here, we observed that transgene expression after transfection was enhanced by treatment with histone deacetylse (HDAC) inhibitors such as trichostatin A, sodium butyrate, and valproic acid. Transfection was performed using conventional transfection reagents with a retroviral vector encoding GFP under the control of CMV promoter as a reporter. Treatment of ES cells with HDAC inhibitors after transfection increased population of GFP positive cells up to 180% compared with untreated control. ES cells showed normal expression of stem cell markers after treatment with HDAC inhibitors. Transgene expression was further enhanced by modifying transfection procedure. GFP positive cells selected after transfection were proved to have the stem cell properties. Our improved protocol for enhanced gene delivery and expression in mouse ES cells without hampering ES cell properties will be useful for study and application of ES cells.

The purpose of this study is to develop three Judo-doll systems for enhancement of Judo's performance. Traditional Judo training requires a human training partner. Unfortunately it is not always easy to find one. Multifunctional Judo-doll training system has therefore been developed, and is described here. The system consists of a dummy, a power generating mechanism, and kinematic links. The power-generating mechanism generates forces similar to those of a human, by adjusting deadweights and controlling powderbrake's forces. The powderbrake force is controlled by the microprocessor according to the exercise scenario. The kinetic links, which mimic a human training partner's motions, has been developed based on a $Vicon^{TM}$ system's analysis of the movement of human training partners. This mechanism whose name is "L link-wire" consists of L type links, wire, roller, and dead weight. This mechanism generates the force that leads the link to the neutral position regardless the link is pushed or pulled. The lifting mechanism that lifts the doll when the one-armed shoulder throw skill is applied is also developed. A 32-bit microprocessor controls the whole system; it reads the loadcell data, controls the electromagnetic force, and communicates with a PC via Bluetooth. The training history, including loadcell data, date, and training time, is stored in the PC for analysis. This training system can be used to enhance the Judo performance of any self training player.
Objectives: The purpose of this study was to know instructors' needs of integrated curriculum in dental hygiene practice.. Methods: A self-reported questionnaire was completed by 112 instructors in Korea from June to July, 2015. The statistical analyses include frequency, percentage and Mann-Whitney' U test using SPSS 12.0 program. The questionnaire comprised needs of curriculum(5 items), integrated curriculum(10 items). Results: Need of integrated curriculum in practice course was statistically significant in school system(p=0.048) and number of students(p=0.041). The enhancement of clinical competence was high in teaching experience($11{\leq}$)(p=0.009) and perceptions of problems was high in experience of teaching($10{\geq}$)(p=0.047). In integrated curriculum, enhancement of clinical competence was statistically significant in school system(p=0.035) and number of students(p=0.011). Increase of professionalism was high in University(p=0.021), number of students(p=0.006) and teaching experience($10{\geq}$)(p=0.062). Conclusions: In order to improve curriculum in each institutions, it is necessary to measure in the view of representative institutions dimensions.
We report the effect of the fabric of the surface microstructure on the CO gas sensing properties of $SnO_2$ thin films deposited on self-assembled Au nanodots ($SnO_2$/Au) that were formed on $SiO_2/Si$ substrates. We characterized structural and morphological properties, comparing them to those of $SnO_2$ thin films deposited directly onto $SiO_2/Si$ substrates. We observed a significant enhancement of CO gas sensing properties in the $SnO_2$/Au gas sensors, specifically exhibiting a high maximum response at $200^{\circ}C$ and quite a low detection limit of 1 ppm level in dry air. In particular, the response of the $SnO_2/Au$ gas sensor was found to reach the maximum value of 32.5 at $200^{\circ}C$, which is roughly 27 times higher than the response (~1.2) of the $SnO_2$ gas sensor obtained at the same operating temperature of $200^{\circ}C$. Furthermore, the $SnO_2/Au$ gas sensors displayed very fast response and recovery behaviors. The observed enhancement in the CO gas sensing properties of the $SnO_2/Au$ sensors is mainly ascribed to the formation of a nanostructured morphology in the active $SnO_2$ layer having a high specific surface-reaction area by the insertion of a nanodot form of Au nucleation layer.
This study was performed to suggest the health management of farmers compared with different farming types, such as rice plant, livestock, horticulture, orchard and others, for the farmer's health enhancement. For this study, 720 subjects were selected in 8 provinces through cluster method, and relevent caculations for the analysis of the subjects were made SAS program, and tested significance with x$^2$ and F value, those probability levels were 0.1%, 1% and 5%. Among the subjects, aged 40's were 38%, females 66%, elementary graduates (32%), and think of living conditions were average (67%). In the self-consciousness test for health, there was no significant difference of farmers with farming types. In the aspect of agricultural work situation, they took holidays according to the weather conditions or no pressed work to be done. And They took a break “when they feel tired during work”. For the recovery of fatigue, sleeping was chosen as the most favorite (68%) followed bathing (17%). but exercise was the lowest (7%). In the case of working conditions, 74% of them replied they work under average condition, and only 9% of them thought they were under pleasant surroundings. And 37% of them have had healthy food, for health practice and restorative for health. 20% of them have had breakfast irregularly. In addition to the regular meal intake, sufficient re자 and pleasant agricultural working conditions would be necessary for health, and the farmers themselves should recognize the importance and care of health. The project for enhancement of the farmers' health is needed and who should give guideline to have the responsibility for health.
The purpose of this study is to develop an altruistic behavior enhancement program for middle school students based on the Maumgram. To do this, we conducted basic research on the altruistic behavior program by collecting and analyzing related literature. The contents of the survey are related to the factors necessary for program analysis and content analysis. It has been validated twice in total by eight experts on the composition and content of the program. The program design consisted of three stages of observation, conversion, and relationship orientation, and selected contents suitable for altruistic programs and conducted them once a week for middle school students, self-inspection, understanding, empathy and communication. However, further study is needed to verify the effect of applying the program in the future. This study will provide basic data on the character education of middle school students by promoting the tendency of altruistic behavior through adjusting training of selfishness.

Human pose estimation is a method of estimating a posture by extracting a human joint key point. When occlusion occurs, the joint key point extraction performance is lowered because the human joint is covered. The occlusion phenomenon is largely divided into three types of actions: self-contained, covered by other objects, and covered by background. In this paper, we propose an effective posture estimation method using a masking phenomenon enhancement technique. Although the posture estimation method has been continuously studied, research on the occlusion phenomenon of the posture estimation method is relatively insufficient. To solve this problem, the author proposes a data augmentation technique that intentionally masks human joints. The experimental results in this paper show that the intentional use of the blocking phenomenon enhancement technique is strong against the blocking phenomenon and the performance is increased.
The purpose of this study was to analyze the educational effect of self-directed learning method using 3D printed anatomy on radiological science students. The subjects were 32 students (20 males and 12 females) in the second year of radiological science at university. They were divided two groups as a non-active student group and an active student group. A learning method was self-directed learning using 3D printed anatomical structures, and the effects of quantitative learning improvement were evaluated before and after the learning. The qualitative evaluation of the students was analyzed on the Likert's 5-point scale for the interest, satisfaction, and learning effects (memorization convenience of anatomy name, radiography Interpret ability, understanding on bones structure, and X-ray projection technique). As a result, the enhancement of learning improved 65.4% on average, and all students got scored high on all variables. Especially non-active student groups showed higher correlation coefficients in all variables except interest and radiography interpret than active student groups. These results might suggest that self-directed learning using 3D printed anatomical structures could have a positive educational effect on radiological science students.
The purpose of this study was to analyze variables associated with smoking and selected health behaviors. This study targeted adult men and women over 20 of age. The sample population was drawn from the national sample, and the samples were chosen from the telephone book. A total of 1,500 cases were collected through a telephone based interview survey. As a tool for this study, a structured questionnaire was developed. the variables included self-perceived health status, and selected 7 health behaviors; smoking behavior, physical activities, eating habit, weight control, alcohol consumption, stress management, and cancer exam. The healthy life practice actions of Trans-theoretical model have been classified into five stages. Smokers were more likely than non-smokers to positive attitudes toward smoking and the impact of smoking in this study. This means that smokers's awareness toward the impact of smoking is very week. Smoking behavior was significantly related to other health related behaviors based on the correlation analysis. However, gender, engaging in regular physical activities, moderate consumption of alcoholic beverages, and receiving a cancer examination were the variables that can explain and predict a person's stages of adopting a non-smoking behavior. Self perceived health status was closely related to other health behaviors. Gender, age, and monthly household income were important demographic variables that have significant relationship with the self-perceived health status. Among the health behaviors, regular physical activities and weight control were significant predictable variables. Similar results have been found in the National health and Nutrition examination survey in Korea. As a result of this study, it was found that among the selected health behaviors, engaging in physical activity was an important variable to increase positive sense of health and non-smoking behaviors. Educational and policy level input is needed to increase awareness and provide chances to participate in fitness activities. To those who maintain exercise, the environmental support and diffusion of knowledge information and education data should be strengthened. To change attitudes toward smoking, more in-dept awareness campaign and education should be provided according to people's different behavioral status. In addition, not only diffusing health education data and delivering knowledge information through related programs, but also environmental support system that helps an individual maintain his/her action is required. Such a support system means settlement of the health enhancement base of school, workplace and community should be carried out, and the policy level support and regular programs should be provided and spread to the unit of community.
