  • The objective of this study was to research the health status of the elderly population and their perception and compliance to cook medicated juk. The results from this research will be used as basic data for medicated juk development. In addition, the purpose of this study was to find a way to popularize the juk and improve their usage as medicated juk in communal feeding and convalescent hospital for elderly. The study surveyed 300 elderly residents of age over 65, in Daejeon. The following data were collected: general characteristic, health status, perception of medicated juk, and preferred kind of juk for cooking. Moreover, the study researched the constraints in cooking the juk. Data were analyzed by SPSS Windows V. 18.0 and t-test verified the differences among the questions, according to frequency analysis of each item and characteristics of the aged. You might want to specify this characteristic. Within the surveyed elderly population, 80.6% had various existing diseases with circulatory diseases being the most prevalent with 68.9%. This emphasizes on the significance of proper diet, but this recognition is not put into practice. The survey also showed that as the individuals age, they tend to care less about the necessity of proper diet. Despite of this lack of perception, 84.5% of the elderly population responded positively to the question, "Would you like to have medicated juk for curing diseases, if such juk is available?" In addition, the elderly population was in favor of developing the juk that helps to prevent and cure diseases, and many were willing to cook them. The reasons behind their will to cook are arranged in the following order: higher efficacy in curing disease than regular juk, excellence in nutrition, and unavailability of the medicated juk in the stores that requires them to cook. The sources constraining the elderly population in cooking are arranged in the following order: not knowing how to cook the juk, lack of physical strength, financial burden, and lack of information order. Please clarify this part. Suggested change: not knowing what medicated juk is. Furthermore, the main obstacle in cooking the juk is lack of cooking technique, followed by inaccessibility to the ingredients and the financial burden to purchase the ingredients.

  • Objective : The purpose of this study was to investigate the strategies used to cope with stress and the cognitive characteristics of somatic symptom perception in patients with panic disorder. Methods : A total of 101 patients who met the DSM-IV criteria for panic disorder and 60 normal controls were recruited for participation in this study. We evaluated the subjects using The Way of Stress Coping Questionnaire (SCQ), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and the Panic Disorder Severity Scale (PDSS). We analyzed the data using an independent t-test and Pearson correlation analysis (p<0.05). Results : The patients who used emotionally focused coping strategies scored significantly lower on the SCQ. The patients with panic disorder showed greater amplification of body sensations in the SSAS, a significantly higher score on the physical interpretation subset of the SIQ, and a lower score on the environmental interpretation subset of the SIQ than the normal controls. The PDSS scores were positively correlated with the SSAS score and physical interpretation score on the SIQ. Conclusion : These results show that patients with panic disorder have poor emotionally focused strategies for coping with stress, greater amplification of body sensations, and a tendency towards a physical interpretation of somatic symptoms.

  • The purpose of this study was to investigate the trait cortical arousal level, measured by extraversion-introversion, in schizophrenics. Subjects in this study were 231 (chronic schizophrenics=78, acute schizophrenics=62, and normal persons=91). All subjects were asked to respond to extraversion-introversion subtest scale in the korean EPQ(Korean Version Eysenck Personality Questionnaire). Collected data were analyzed by using the t-test and one-way analysis of variance. Results were as follows : 1) Trait cortical arousal level of chronic schizophrenics, which was measured by extraversion-introversion subtest scale in the Korean EPQ, was statistically higher than that of acute schizophrenics and normals. 2) Acute schizophrenics and normals were not significantly different in the trait cortical arousal level. However, the trait cortical arousal level of chronic schizophrenics was higher than that of acute schizophrenics. Therefore, it may state that the trait cortical arousal level of schizophrenics is getting higher when schizophrenic symptoms become more chronic.

  • Background: Breast cancer (BC) is the most frequent cancer type, and the leading cause of death from cancer among women in Israel. The Bedouin-Arab (BA) population in southern Israel is characterized by a high rate of consanguinity, common hereditary disorders, and transition from a semi-nomadic, traditional society to a more sedentary and urbanized society. In this hospital-based study, the demographic and the clinicopathological characteristics of BC in BA were compared with Jewish patients. Materials and Methods: 85 BA patients treated at the Soroka Medical Center, Beer Sheba, during the years 2004-2012, were studied and compared with 180 consecutive Jewish patients treated during the year 2007. Clinicopathological features compared included age, menopausal state, number of births, a history of BC in first-degree relatives, tumor size (T), extent of lymph-node involvement (N), distant metastases (M), stage, grade, estrogen and progesterone receptor (ER/PR), and Her2 status. Types of treatment, relapse rate and site, as well as outcome were also studied. Cox's regression models were applied for studying disease-free, and overall survival. Results: Compared with Jewish patients, BA patients were younger (average age $49{\pm}12$ yrs vs $59{\pm}13$, p<0.001), had a lower rate of BC in first-degree relatives (p<0.001), and a larger number of births ($6{\pm}4.2$ vs $2.5{\pm}1.9$, p<0.001). BA patients had larger tumors (p=0.02), more extensive lymph-node involvement (p=0.002), and more advanced stage (p=0.003). Grade, ER, PR, and Her2 status were similar in the two ethnic groups. Relapse type was most commonly systemic in BA patients (p=0.05), and loco-regional in Jewish patients (p=0.02). Median survival was 63, and 35 months for Jewish and BA patients, respectively (log-rank test, p=0.02). In Cox multivariate analysis, stage and PR status (HR-0.14, p<0.0001; HR-3.11, p=0.046), but not ethnicity, influenced overall survival. Conclusions: BC presents a decade earlier, and with more advanced disease in BA compared with Jewish patients. Biologic parameters including grade, ER, PR, and Her2 status were similar in both groups. Although prognosis was worse in BA than in Jewish patients, it was affected only by stage and PR status, but not by ethnicity.

  • The purposes of the study were to identify satisfaction and achievement of learning by female learner's characteristics, and to suggest measures to improve quality of education in internet education programs. In order to determine the educational effectiveness associated with the characteristics of learners, this study attempted to employ two way approaches by observing the degree of achievement for learning, which represents an instructor-oriented approach, and the degree of satisfaction for education, which represents a learner-oriented approach to enhance the quality of internet education for female learners. As an approach to evaluate the educational effectiveness, the degree of achievement in learning(Tyler's classical approach), and the degree of satisfaction for education (Scriven's consumer-oriented evaluation model) were utilized. A survey form was developed by the researcher after reviewing the various tools originated from Boshier, Cross, Gagne and Choi, and distributed to a panel of judges that examined the content validity of the instrument. The sample for the study consisted of 160 female learners from three universities in Seoul and capital area, and the survey form was used to collect data for this study. The SPSS WIN program was used in analyzing the data and a series of statistical tests were conducted including frequency, percentile, t-test, ANOVA, correlation, multiple regression, and factor analysis. The statistical significance level was 0.05. The following conclusion were drawn from this study of female internet education. First, it was evident that female internet learners tend to utilize information from internet, and this can be interpreted as participants' positive attitude, and voluntary participation. Second, educational facilities and services should be improved in the future, because the level of satisfaction was low in these areas compared to curriculum and educational methodology. Third, the participating factors influenced by the level of satisfaction for education of learner characteristics were the 'formation of inter-personal relationship and willingness to change' and the 'needs for education on internet', thus appeared that both social and educational needs influenced the level of satisfaction for education. Fourth, the degree of achievement in learning was higher in the order of 1) attitude 2) function 3) knowledge, thus, attitude change was the most important in achievement of learning. Fifth, the individual background that influenced the level of achievement in learning were age and educational experience. As for the individual level of achievement for learning, the younger and more educated group were more satisfied.

  • This study attempted to identify the entrance exam stress levels in high school students and analyze the relationship this entrance exam stress and perceived oral health status. Self-administered survey was conducted in total 304 students attending in academic high schools in Bucheon. For analysis, SPSS was used to perform t-test and one-way ANOVA. As a result of the study, the entrance exam stress level of academic high school students was 2.71. The level of sub-factors were that tension for exam/poor result was highest by 3.08 and the next were future uncertainty (2.81), parents pressure (2.56), and insufficient free time (2.52). The group with high entrance exam stress showed significantly high perceived degrees of temporomandibular disorder, oral mucosal disease and xerostama. Among sub-factors of stress, the group with high tension for exam/poor result stress had significantly high perceived degrees of dental caries, teporomandibular disorder, oral mucosal disease and xerostama. Because perception on oral health issues increased with high entrance exam stress in high school students, it is necessary to seek some ways to decrease oral health problems even though entrance exam stress is intensified. To do so, it is inferred that it will be very important to promote oral health education to develop ability of high school students to practice correct oral management method.

  • As requirements of embedded system get complicated, the tool for analyzing the reliability of embedded software is being needed. A probabilistic modeling is used as the way of analyzing the reliability of a software and to apply it to embedded software controlling multiple devices. So, it is necessary to specialize that to embedded software. Also, existing reliability analyzers should measure the transition probability of each condition in different ways and doesn't consider reusing the model once used. In this paper, we suggest a reliability analyzer for embedded software using embedded software Markov chin model and a unit testing tool. Embedded software Markov chain model is model specializing Markov chain model which is used for analyzing reliability to an embedded software. And a unit testing tool has host-target structure which is appropriate to development environment of embedded software. This tool can analyze the reliability more easily than existing tool by automatically measuring the transition probability between units for analyzing reliability from the result of unit testing. It can also directly apply the test result updated by unit testing tool by representing software model as a XML oriented document and has the advantage that many developers can access easily using the web oriented interface and SVN store. In this paper, we show reliability analyzing of a example by so doing show usefulness of reliability analyzer.

  • Objectives: The purpose of the study was to investigate the associated factors with oral health behavior in public health majoring students. Methods: Using convenience sampling method, the subjects were 474 health-related majoring students in Jeollanamdo. A self-reported questionnaire was completed from September 1 to 15, 2014. The questionnaire consisted of general characteristics of the subjects, oral health related characteristics, oral health knowledge and behavior. Data were analyzed using SAS 9.3 version. T-test, ANOVA, correlation and multiple linear regression analyses were performed to evaluate the related factors with oral health behavior. Cronbach's ${\alpha}$ in oral health knowledge in this study was 0.52 and that in oral health behavior was 0.80. Results: The overall score of oral health behavior was $3.38{\pm}0.52$. Of all behaviors, the practice in brush of teeth and tongue had the highest mean score. In multiple regression analysis, oral health knowledge in the nursing and dental hygiene students was positively associated with the oral health behavior(${\beta}=0.04$, p=0.003, ${\beta}=0.23$, p=0.003, and ${\beta}=0.18$, p=0.034, respectively). Necessity of dental care, one of oral symptom, and more than two oral symptoms were negatively associated with oral health behavior(${\beta}=-0.14$, p=0.002, ${\beta}=-0.11$, p=0.037, and ${\beta}=-0.17$, p=0.011, respectively). Conclusions: Higher oral health knowledge showed higher levels of oral health behavior. These results will enhance the quality of oral health behavior by increasing the level of oral health knowledge. The optimal oral health education program would be able to improve oral health behavior by increasing the level of oral health knowledge.
