The starting point of this study is the concerning of simple behavioral pattern that whoever enters the inner space with taking off his shoes should go out from the position where he laid his shoes. The using of Ondol (floor heating room) and Maru (lifted wood floor) had changed the architectural space from chair-sitting to floor-sitting space, and it also made the behavior of taking off the shoes at the entrance of building and stepping on the lifted floor. This simple behavior has possibility to make lots of changes to the culture of architectural design. With this noticeable point, this paper is talking about the cultural feature of Korean traditional architecture, especially about the influence of tanking off and putting on shoes. The matter of shoes has changed diverse aspects of building and layout planning. It maximized the difference between front and rear part of building and characterized the lateral extension of Korean traditional house. The ritual space also had evolved from chair-sitting to floor-sitting space according to the type of ritual behavioral pattern. The change on the single building level had influenced on the layout planning of architectural complex. For examples, the parallel layout of ChangDeok-gung palace and the long sequential process to the main pavilion of Buddhist temple are the result of the matter of shoes. And NuGak(樓閣), the double-storied pavilion, on the axis of entering sequence's node is one of the unique planning elements that makes possible to go through the building without taking off the shoes and also makes upper level space for staying. In short, Korean traditional architecture that has the chair-sitting spatial origin of the East Asian cultural sphere has pursued new architectural issues and planning methods according to evolution to the floor-sitting culture.

The purpose of this study was to find out the physical change of the farm house and its anbang(the main room : master bed room), to identify the behavioral changes : activity and awareness of anbang, and to clarify the relationship between the physical changes of the farm house, and the behavioral changes of housing life-style in the anbang space. Bibliographical studies, cultural approaches and field survey method with questionnaire were used to collect data from 55 residents of Anwhari and Yangkyori in Pyong Teck Koon. Tables and drawings were made to analyze the data. The major findings were 1) the heating system of the ondol anbang. The most popular type is the double heating system(new pipes added to the traditional ondol). This combination ondol system brought some conviniences to the farmers. This change in structure of the ondol were of four types : Complete change in style, enlarged-completely changed style, partially changed style, enlarged-partially changed style. 2) from 1960 through 1970 lighting of the anbang changed room oil lamp to electricity. 3) the finishing material of the anbang floor changed from traditional oil paper and straw mats to vinyl flooring. 4) Traditional furniture and small decor items are gradually disappearing and are being replaced by modern items. 5) The awareness and actual use of the ondol anbang has not much changed from the multi-functional and sacred space of daily living : which are the characteristics of Korean traditional ondol anbang. The biggest consistency in the ondol anbang is the heating system of the floor, which is the characteristic of ondol culture in Korea. This system will continue regardless of time and place in Korea.

Mucopolysaccharidosis IIIA is a heritable neurodegenerative disorder resulting from the dysfunction of the lysosomal hydrolase sulphamidase. This leads to the primary accumulation of the complex carbohydrate heparan sulphate in a wide range of tissues and CNS degeneration. Characterization of animal model is the beginning point of the therapeutic clinical trial. Mouse model has a limitation in that it is not a human and does not have all of the disease phenotypes. Therefore, delineate of the phenotypic characteristics of MPS IIIA mouse model prerequisite for the enzyme replace treatment for the diseases. We designed 6-month duration of phenotypic characterization of MPS IIIA mouse biochemically, behaviorally and histologically. We compared height and weight of MPS IIIA mouse with wild type from 4 weeks to 6 months in both male and female. At 6 months, we measured GAG storage in urine kidney, heart, liver, lung and spleen. The brain GAG storage is presented with Alcian blue staining, immunohistochemistry, and electron-microscopy. The neurologic phenotype is evaluated by brain MRI and behavioral study including open field test, fear conditioning, T-maze test and Y-maze test. Especially behavioral tests were done serially at 4month and 6month. This study will show the result of the MPS IIIA mouse model phenotypic characterization. The MPS IIIA mouse provides an excellent model for evaluating pathogenic mechanisms of disease and for testing treatment strategies, including enzyme or cell replacement and gene therapy.

Objectives : This study is to investigate factors that predispose the oral health education patterns of teachers at preschool institutions such as kindergartens and day nurseries, for which a comparison was made among the patterns, whereto the PRECEDE model was applied. Methods : A survey was conducted by two visits, a preliminary survey and a main survey, and teachers at the foregoing institutions personally filled in the questionnaire. Results : 1. With relation to epidemiological and social diagnosis, the largest number of respondents (53.7%) agreed on the need for oral health education, but at the same time, the largest number of respondents (40.3%) was unsatisfactory with oral health education given by them. 2. With relation to behavioral diagnosis, there were many cases where respondents taught their students to brush their teeth after meals and snacks. Oral health education was focused on safety and injuries. There was no significant intergroup difference (p>0.05). 3. Predisposing factors (a subcategory of educational diagnosis) showed the following results: As for the frequency of oral health education, most respondents at both institutions answered preferred once every six month (p>0.05). In the case of oral health checkup, 75.4% of respondents at kindergartens preferred once a year. 72.2% of respondents at day nurseries preferred the same frequency. They showed a statistically significant difference (p<0.05). In enabling factors, it was found that most respondents at both institutions collected information and teaching materials from mass media and public health centers respectively. In enabling factors, insufficient teaching materials, media and knowledge were found to be obstacles to oral health education. Conclusions : Oral healthcare providers' cooperation is required to diversify away from tooth brushing-centered education and to enrich oral health education. In addition, continuous supplements are required to make teachers at preschool institutions acquire expert knowledge and give oral health education with confidence. Moreover, it needs to train them for various education programs as well as to support them with educational media. Lastly, family members' cooperation is required to develop oral health education programs.

The purpose of this study was to investigate the psychosocial factors influencing dairy product consumption of female university students in Daejeon. The Theory of Planned Behavior provided the basis for this study. As a result of the pilot-study, 18 behavioral beliefs, 8 normative beliefs, and 12 control beliefs were identified. The subjects (n=236) were grouped into a high-consumption group (1 serving/day, n=117) and a low consumption group (< 1 serving/day, n=119). The data were analyzed using t-tests or $\chi$$^2$-tests. Among the general characteristics, there were significant differences in the amount of pocket money spent per month, residence type (p<0.01), weight, frequency of exercise and perceived health status (p<0.05) of the subjects. With respect to the 18 behavioral beliefs, the high consumption group responded less negatively on ‘eating dairy foods would not be convenient’ than the low consumption group (p<0.05). None of the subjective normative items were significantly different between the two groups. However, notable differences were found in regard to the control beliefs (8 out of 12 control beliefs). These included overall control over consuming dairy products (p< 0.001), as well as specific beliefs regarding barriers such as easy spoilage of dairy products, the cost, eating them for snacks and dislike for them (p<0.05). In addition, specific situations, such as ‘when I want them I get them’ (p<0.01), eating out and the availability of dairy foods at home (p<0.05) were significantly different between the two groups. The high consumption group showed more control over these barriers or situations. These results suggest that nutritional education for young female adults should incorporate strategies to increase their perceived control over the consumption of dairy products by removing barriers and including environmental approaches which address the availability issues.

The objective of this study is to investigate college student search behavior in an academic library. The theory of planned behavior was applied for identifying relationship among variables on search behavior. Data were collected in an university. For data analysis, ANOVA, factor analysis, regression analysis, cluster analysis were used. The result shows: the theory of planned behavior can be used for finding search intention in an academic library. Student major and library use frequency are different statistically in attitudes, perceived behavioral control, behavioral intention. Student characteristics are divided into four types: conservative, independent, friendship, fashion. Friendship type of students influences search behavior. From cluster analysis, the cluster included friendship and independent types of students and students who have high frequency of library use has more active intention for search in academic library.

Purpose: This study aimed to explore the subjective perception structures and types of empathy among nurses caring for patients with behavioral and psychological symptoms of dementia (BPSD) using Q-methodology. Methods: Thirty-eight Q-samples (statements) were derived from in-depth interviews with 10 nurses working in long-term care hospitals and nursing homes. The Q-sorting was conducted in rank order (the responses obtained by each of the 30 nurses working at 3 long-term care hospitals and 4 nursing homes) into a normal distribution grid (from -4 to +4). The types of empathy among participants were analyzed using the PC-QUANL program. Results: Five types of empathy accounting for 48.5% of the total variance were categorized as follows: (1) taking the patients' personality into consideration while helping, (2) interacting closely and emotionally, (3) supporting the patient as a companion, (4) performing the duty in a defensive manner, and (5) resolving patients' problems by focusing on their needs. Conclusion: This study shows that there are various types of empathy in nurses caring for patients with BPSD. Therefore, it is necessary to develop strategies and educative programs to enhance empathy competency and deal with burnout based on the type of empathy.

Treatment of obesity includes diet therapy, exercise therapy, cognitive behavioral therapy, drug therapy, and bariatric surgery. Most obese patients lose weight by combining diet, exercise, cognitive behavioral therapy or medication. But, in some cases, only one of these treatments is preferred. A 56-year-old male patient had a body mass index (BMI) of 33.1 kg/m² and a waist circumference of 108 cm. He had been treated for hypertension; diabetes and dyslipidemia were diagnosed but not treated. However, at the initial visit to treat obesity, he was diagnosed with type 2 diabetes mellitus and dyslipidemia again. So he decided to treat these two diseases with drugs first and modify his lifestyle. He started walking more than 20,000 steps every day and then he really walked about 15,000 steps every day during 5 months, although diet calorie or alcohol drinking amount was not significantly decreased. After about 6 months, the patient's weight decreased by 10.1 kg, the BMI decreased by 4.1 kg/m², the waist circumference decreased by 10 cm, the glycated hemoglobin (HbA1c) decreased by 4.59%, the visceral fat area decreased by 115 cm², and the subcutaneous fat decreased by 38 cm². As a result of body composition analysis, muscle mass increased by 1.2 kg, and the percentage of body fat decreased by 10.4%. The walking exercise does not have any space restrictions and has high accessibility by using a mobile phone app. Therefore, considering the patient's situation, it would be better to treat obese patients by first recommending walking exercises and increasing the number of steps to lose weight and improve the comorbidities.

Drug addiction influences most communities directly or indirectly. Increasing studies have reported the relationship between circadian-related genes and drug addiction. Per2 disrupted mice exhibited more vulnerable behavioral responses against some drugs including methamphetamine (METH). However, its roles and mechanisms are still not clear. Transcriptional profiling analysis in Per2 knockout (KO) mice may provide a valuable tool to identify potential genetic involvement and pathways in enhanced behavioral responses against drugs. To explore the potential genetic involvement, we examined common differentially expressed genes (DEGs) in the striatum of drug naïve Per2 KO/wild-type (WT) mice, and before/after METH treatment in Per2 KO mice, but not in WT mice. We selected 9 common DEGs (Ncald, Cpa6, Pklr, Ttc29, Cbr2, Egr2, Prg4, Lcn2, and Camsap2) based on literature research. Among the common DEGs, Ncald, Cpa6, Pklr, and Ttc29 showed higher expression levels in drug naïve Per2 KO mice than in WT mice, while they were downregulated in Per2 KO mice after METH treatment. In contrast, Cbr2, Egr2, Prg4, Lcn2, and Camsap2 exhibited lower expression levels in drug naïve Per2 KO mice than in WT mice, while they were upregulated after METH treatment in Per2 KO mice. qRT-PCR analyses validated the expression patterns of 9 target genes before/after METH treatment in Per2 KO and WT mice. Although further research is required to deeply understand the relationship and roles of the 9 target genes in drug addiction, the findings from the present study indicate that the target genes might play important roles in drug addiction.

Bellows are corrugated mechanical elements used to absorb displacements or vibrations caused by temperature changes, pressure, earthquakes, waves, etc., which are welded to flanges or directly connected to pipes. Expansion joint bellows must not only be designed to sufficiently withstand the internal pressure of the pipes but also accommodate axial, transverse, and rotational deformations to minimize the transfer of forces to the sensitive components of the system. Bellows have various types of corrugations, but U-type bellows are most commonly used in general piping systems. In this study, the behavior of U-shaped one-, two-, and three-ply bellows with the same inner diameter under pressure and forced displacement was analyzed using the finite element method. The results were compared with the design formula in the Expansion Joint Manufacturers Association (EJMA)'s code. Manufacturer data were used for the applied pressure and force displacement. The behavioral characteristics of the three cases were compared via structural analysis because the stress levels will be different for each model, even if they have the same inner diameter. Since the analytical model has an axisymmetric shape but displacement occurs in the transverse direction, the finite element model was composed of 1/2 of the whole model, and ANSYS Workbench 17.2 was employed for the analysis.
