  • The purpose of this study is to evaluate the effect of PBL program for cooperative practice between western and korean medicine. Third and fourth grade medical and Korean medical school students (experimental group: 16 students, respectively) in the Pusan National University were included in the study. Teaching methods was Problem-Based Learning (PBL) which was consist of 4 western and 4 korean medical students and 2 tutors. Modules have been developed by 8 subject experts or educational experts, who have also participated in the PBL as tutor. The program has been proceeded for 4 weeks, where two face-to-face discussions and self-directed learning were done in each module. In experimental group, students' perceptions about the other medicine were surveyed before and after the program and students' and tutors' satisfaction on the program was investigated. The perception survey was also done in the control group at the beginning of the study. The students who participated in this program had more positive perceptions about the other medicine, compared with control group. There were only significant increases on the items of 'understanding of the other medicine' between before and after the program, where no statistical differences were not observed in 'perception of the other medicine or cooperative practice'. Satisfaction in the program was positive.The PBL program enabled students to understand the other medicine, but it didn't lead changes of their perception. To improve students' perception, the program need to be kept steadily.

  • In this paper, we deal with the following system of nonlinear singular boundary value problems(BVPs) on time scale $\mathbb{T}$ $$\{{{{{{x^{\bigtriangleup\bigtriangleup}(t)+f(t,\;y(t))=0,\;t{\in}(a,\;b)_{\mathbb{T}},}\atop{y^{\bigtriangleup\bigtriangleup}(t)+g(t,\;x(t))=0,\;t{\in}(a,\;b)_{\mathbb{T}},}}\atop{\alpha_1x(a)-\beta_1x^{\bigtriangleup}(a)=\gamma_1x(\sigma(b))+\delta_1x^{\bigtriangleup}(\sigma(b))=0,}}\atop{\alpha_2y(a)-\beta_2y^{\bigtriangleup}(a)=\gamma_2y(\sigma(b))+\delta_2y^{\bigtriangleup}(\sigma(b))=0,}}$$ where $\alpha_i$, $\beta_i$, $\gamma_i\;{\geq}\;0$ and $\rho_i=\alpha_i\gamma_i(\sigma(b)-a)+\alpha_i\delta_i+\gamma_i\beta_i$ > 0(i = 1, 2), f(t, y) may be singular at t = a, y = 0, and g(t, x) may be singular at t = a. The arguments are based upon a fixed-point theorem for mappings that are decreasing with respect to a cone. We also obtain the analogous existence results for the related nonlinear systems $x^{\bigtriangledown\bigtriangledown}(t)$ + f(t, y(t)) = 0, $y^{\bigtriangledown\bigtriangledown}(t)$ + g(t, x(t)) = 0, $x^{\bigtriangleup\bigtriangledown}(t)$ + f(t, y(t)) = 0, $y^{\bigtriangleup\bigtriangledown}(t)$ + g(t, x(t)) = 0, and $x^{\bigtriangledown\bigtriangleup}(t)$ + f(t, y(t)) = 0, $y^{\bigtriangledown\bigtriangleup}(t)$ + g(t, x(t)) = 0 satisfying similar boundary conditions.

  • The purpose of this study was to estimate the nutrient intake, dietary habits, and body indices among preschool children. The study subjects were 166 kindergarten children, aged 4 to 6 years. A measurement of the weight, height, chest circumference, and head circumference of the children was conducted. The general home environment and factors related to the eating habits of children were collected using a questionnaire that included information about physical activity, outdoor playing time, television watching, family income, and parents education and occupations. Underweight, overweight were defined based on a value of less than 110 and more than 140 on the Rohrer Index, or less than 90 and more than 120 on the weight-length index (WLI). The average Rohrer and WLI for the preschool children were 14.3 $\pm$ 23.2% and 104 $\pm$ 13.5%. Using the WLI, 12.7% of the preschool children were underweight 62.6% were normal, and 24.7% were overweight or obese. On the Rohrer Index, 32.0% of the preschool children were underweight, 34.7% were normal, and 34.1% were overweight or obese. With regard to frequency of regularity of eating breakfast, 2.5% of preschool children skipped breakfast every morning. The risk of being overweight increased in preschool children who had faster eating times. The Rohrer and WLI were negatively related to faster eating times. The average daily energy intake was 1272 Kcal, which corresponded to 79.5% of the Korean RDA. In particular, the average intakes of calcium, iron, and vitamin B$_2$ were much lower than the Korean RDAs for each of those nutrients. Children whose mothers had occupations were at greater risk of decreased nutrient intake than those whose mothers were at home. The data presented in this study confirm that, in preschool children, undernutrition remains the nutritional problem of great concern in Korea, even though Koreans are starting to have worrisome rates of overweight. Therefore, during the early years of life, focus should remain on sustaining Proper growth and development.

  • 각 교과의 교사들이 효과적으로 수업을 전개하기 위해서는 사전에 수업 전개 과정을 설계할 필요가 있다. 전통적으로 교수설계에 널리 적용되고 있는 모형으로는 딕과 케리, ADDIE, ASSURE 등이 있다. 그러나 전통적인 교수설계 모형은 교과 내용이 소규모 단원으로 분절되어 있어서 학생들이 교과의 본질적인 이해에 이르기 어렵다는 한계가 있다. 이러한 문제를 해결하기 위해서 위깅스와 멕타이는 백워드 설계 모형을 제안하였다. 백워드 설계 모형은 가르쳐야 할 내용과 활동을 결정하기 전에 먼저 평가를 고려하는 교수설계 방법이다. 이에 본 연구에서는 백워드 모형의 구조를 분석하고, 정보활용교육을 위한 '도서관과 정보생활' 교과에 백워드 설계 모형을 적용함으로써 정보활용교육의 효과적인 교수-학습 방법을 모색하고자한다. 본 연구에서는 '도서관 과 정보생활' 교과의 백워드 교수설계를 위해서 위깅스와 메타이가 고안한 템플릿을 적용하였다.

  • This study was aimed to analyze - focusing on the thesis of Younes - the pronunciation error occuring mostly for Arabian speakers to learn French pronunciation for Arabians and to suggest the effective study plan to improve such errors and provide the effective studying method. The first part is on how the Arabic and French pronunciation system are distinguished, especially by comparing and analyzing the system of graphemes and phonemes, with which we focused on the fact that Arabian is a language centralized on consonants, while French is a verb-centered language. In the second part, we mainly discussed the cause and the types of errors occurring when Arabic speakers study French pronunciation. As of the category of mistakes, we separated them into consonants and verbs. We assumed the possible method which can be used in learning, focusing on /b/, /v/, /p/, /b/ - in case of non-verbs and consonants - and /y/, /ø/, - in case of verbs - which don't exist in Arabic pronunciation system. One of the troubles the professors in Arabian culture have in teaching French to native learners is how to solve the problem on a phonetic basis regarding speaking and reading ability, which belong to verbal skill, among the critical factors of foreign language education, which are listening, speaking, reading, and writing skills. In fact, the problems occuring in learning foreign language are had by not only Arabian learners but also general groups of people who learn the foreign language, the pronunciation system of which is distinctly distinguished from their mother tongue. The important fact professors should recognize regarding study of pronunciation is that they should encourage the learners to reach the acceptable level in proper communication rather than push them to have the same ability as the native speakers, Even though it cannot be said that the methods suggested in this study have absolute influence in reducing errors when learning French pronunciation system, I hope it can be at least a small help.

  • This research was aimed at studying the situation, problems, and requirements for digital collection lifecycle management of Thai theses and dissertations. The mixed research method used was composed of: (1) Study of the problem and situation in which the qualitative method was applied. The research site covered 10 higher education institutions where the Thailand Digital Collection (TDC) project is operated. The informants were key administrative officers of the TDC project of each institution. In-depth and structured interviews were conducted on an individual basis to obtain the most accurate answers. (2) Study of requirements based on the quantitative research method to survey the requirements for the digital collection management system for Thai theses and dissertations from 84 purposively-selected TDC project officers and 527 end users selected by accidental sampling, totaling 611 samples. Research findings are as follow: (1) The study of the situation and problems of digital collection lifecycle management shows that Thai higher institutions systematically manage their digital collection. The management lifecycle is consistent with the Guidance documents for lifecycle management of ETDs, which included seven steps: program planning, creation, submission, and ingestion, access and retrieval of digital objects, archiving and preservation, evaluation and assessment, interoperation (creation of institutional collaboration), and development of link data. (2) The study of requirements for digital collection management of Thai theses and dissertations shows five system requirements: acquisition and gathering, digitization, metadata standards, management of rights, and storage and retrieval, all of which are at M (mandatory) and D (desirable) levels.

  • Background: Disabling fatigue is common in the working age population. It is essential that occupational health (OH) professionals are up-to-date with the management of fatigue in order to reduce the impact of fatigue on workplace productivity. Our aim was to evaluate the impact of one-day workshops on OH professionals' knowledge of fatigue and chronic fatigue syndrome (CFS), and their confidence in diagnosing and managing these in a working population. Methods: Five interactive problem-based workshops were held in the United Kingdom. These workshops were developed and delivered by experts in the field. Questionnaires were self-administered immediately prior to, immediately after, and 4 months following each workshop. Questionnaires included measures of satisfaction, knowledge of fatigue and CFS, and confidence in diagnosing and managing fatigue. Open-ended questions were used to elicit feedback about the workshops. Results: General knowledge of fatigue increased significantly after training (with a 25% increase in the median score). Participants showed significantly higher levels of confidence in diagnosing and managing CFS (with a 62.5% increase in the median score), and high scores were maintained 4 months after the workshops. OH physicians scored higher on knowledge and confidence than nurses. Similarly, thematic analysis revealed that participants had increased knowledge and confidence after attending the workshops. Conclusion: Fatigue can lead to severe functional impairment with adverse workplace outcomes. One-day workshops can be effective in training OH professionals in how to diagnose and manage fatigue and CFS. Training may increase general knowledge of fatigue and confidence in fatigue management in an OH setting.

  • 딥러닝을 이용한 객체 검출의 경우 정확도와 실시간성을 모두 요구한다. 그러나, 한정된 자원 환경에서는 수 많은 양의 데이터를 처리하는 딥러닝 모델을 사용하기 어렵다. 이러한 문제 해결을 위해 본 논문에서는 소형임베디드 장치를 위한 객체 검출을 모델을 제안하였다. 일반적인 검출 모델과 달리 사전 학습된 특징 추출기를 제거한 구조를 사용하여 모델 크기를 최소화하였다. 모델의 구조는 경량화된 컨볼루션 블록을 반복해서 쌓는 구조로 설계하였다. 또한, 검출 오버헤드를 줄이기 위해 영역 제안 횟수를 크게 줄였다. 제안하는 모델은 공개 데이터 셋인 PASCAL VOC를 사용하여 학습 및 평가하였다. 모델의 정량적 평가를 위해 검출 분야에서 사용하는 average precision으로 검출 성능을 측정하였다. 그리고 실제 임베디드 장치와 유사한 라즈베리 파이에서 검출 속도를 측정하였다. 실험을 통해 기존 검출 방법 대비 향상된 정확도와 빠른 추론 속도를 달성하였다.
