Numerical simulation is a good way to predict the conversion efficiency of solar cells without a direct experimentation and to achieve low cost and high efficiency through optimizing each step of solar cell fabrication. TOPCon industrial solar cells fabricated with n-type silicon wafers on a larger area have achieved a higher efficiency than p-type TOPCon solar cells. Electrical and optical losses of the front surface are the main factors limiting the efficiency of the solar cell. In this work, an optimization of boron-doped emitter surface and front electrodes through numerical simulation using "Griddler" is reported. Through the analysis of the results of simulation, it was confirmed that the emitter sheet resistance of 150 Ω/sq along the front electrodes having a finger width of 20 ㎛, and the number of finger lines ~130 for silicon wafer of M6 size is an optimized technology for the front emitter surface of the n-type TOPCon solar cells that can be developed.

최근 금연 캠페인에서 사실적 이미지가 적극적으로 활용되고 있다. 캠페인을 위한 매체로 활용되고 있는 포스터의 이미지 표현에 있어서도 마찬가지이다. 본 연구에서는 세계보건기구(WHO)에서 제작 배포한 금연 캠페인 포스터에서 서로 다른 시각적 표현 유형이 헬스커뮤니케이션에 미치는 영향을 살펴보았다. '일러스트 이미지'와 '사실적 이미지'가 계획된 행동 이론의 각 속성인 '금연행동 인식', '주관적 규범', '지각된 통제감'에 미치는 영향을 분석하였다. 이미지 표현 유형에 따라 '금연행동 인식'과 '주관적 규범'에 미치는 영향 차이가 있었으며, '지각된 통제감'에서는 두 이미지 표현 유형 사이에 의미 있는 차이가 발견되지 않았다. 본 연구를 통해 이미지 표현 유형 사이에 헬스커뮤니케이션 효과의 차이가 있음을 확인하였으며, 향후 헬스커뮤니케이션에서 효율적인 시각적 표현 방식을 모색하기 위해 디자인 분야와 예컨대 사회 심리학 등 다른 분야 간의 융합적 연구가 요구된다.

The main purpose of the present study is to investigate the citation habit of Korean social scientists by making use of citation analysis and content analysis, and to assess the nature of interdisciplinary flow of information in Korea in terms of the citation dependency on other disciplines, the types of channels used in formal scientific communication, the countries published the literatures of other disciplines cited in the source articles, and the languages used in the literatures of other disciplines. The major findings and conclusions reached at this study are summarised as follows: 1. Korean social scientists mainly cite the literatures of economics, sociology, politics, and history when they cite the literature of other disciplines. 2. The citation dependency on other disciplines of the economists, polictial scientists, and sociologists are 6 percents, 14 percents, and 19 percents, respectively. 3. The citation dependency on history of the economists is 25 percents, the dependency on sociology of the political scientists is 34.9 percents, and the dependency on economics of the sociologists is 50. 19 percents. 4. The types of channels used in formal scientific communication in social sciences are firmly book and journal. 5. The countries published the literatures of other disciplines .cited in the source articles are Korea and the U. S. firmly. 6. The languages used in the literatures of other disciplines cited in the source articles are Korean and English overwhelmingly.

This study was designed to suggest an assessment tool for analyzing the characteristics of Korean phonetic contrast intelligibility among dysarthric individuals. The intelligibility deficit factors of phonetic contrast in Korean dysarthric patients were analyzed through stepwise regression analysis. The 19 acoustic-phonetic contrasts proposed by Kent et al. (1999) have been claimed to be useful for clinical assessment and research on dysarthria. However, the test cannot be directly applied to Korean patients due to linguistic differences between English and Korean. Thus, it is necessary to devise a Korean word intelligibility test that reflects the distinct characteristics of the Korean language. To identify the speech error characteristics of a Korean dysarthric group, a Korean word list was audio-recorded by 3 spastic, 4 flaccid, and 5 mixed type of dysarthric patients. The word list consisted of monosyllabic consonant-vowel-consonant (CVC) real word pairs. Stimulus words included 41 phonemic contrast pairs and six triplets. The results showed that the percentage of errors in final position contrast was higher than in any other position. Unlike the results of previous studies, the initial-position contrasts were crucial in predicting the overall intelligibility among Korean patients.

Dye-sensitized solar cells (DSSCs) have been widely investigated as a next-generation solar cell because of their simple structure and low manufacturing cost. The $TiO_2$ film with thickness of $8{\sim}10{\mu}m$, which consists of nanoparticles, acts as both a scaffold with a high surface-to-volume ratio for the dye loading and a pathway to remove the electrons. However, charge carriers have to move across many particle boundaries by a hopping mechanism. So, one dimensional nanostructures such as nanotubes, nanorods and nanowires should improve charge carrier transportation by providing a facile direct electron pathway and lowering the diffusion resistance. However, the efficiencies of DSSCs using one dimensional nanostructures are less than the $TiO_2$ nanoparticle-based DSSCs. In this work, the patterned $TiO_2$ film with thickness of $3{\mu}m$ was deposited using photolithography process to decrease of electron pathway and increase of surface area and transmittance of $TiO_2$ films. Properties of the patterned $TiO_2$ films were investigated by various analysis method such as X-ray diffraction, field emission scanning electron microscopy (FESEM) and UV-visible spectrophotometer.

Relationship between parent and children is basic relation and initial relationship. It is essential research to explore relationship between parent's role satisfaction and children's health promotion in rapidly changing social situation influence parenting attitude. The purpose of this research to explore first mother's parenting belief, communication, filial piety by indepth interview and literature review. Method of research is literature review (books and articles) and Web site researching (home page) and contacted two mothers to do individual interview. Data was collected and analysed according to the objectives. The result of this study as follows. 1) It was problem that is child rearing and child education due to working parents. 2) It was discussed parent's belief regarding child rearing. The belief was influence by culture, social economic status, family friend and internet, advise of professionals. The subjects of this study was influenced by family, friend and internet Web site. 3) Parent-child communication was reviewed and discussed about influence of masmedia and early education system. Children's level of language development was rapidly improved by role play and read the book with mother. 4) It was discussed concept of filial piety. Parent was not expected filial piety from their children. Parent thought that they already received filial piety from their children, because children gave them pleasure and happiness during growing process. Parents want their children become mature person and adapt to informative changing society. Finally, it is needed further interdisciplinary study for parent-child health promotion and growth and development in rapidly changing society.

Purpose: The paper employs the theory of planned behaviour, social identity theory, social presence theory, and social exchange theory to propose a model for using the social media platform Facebook in distributing information in universities. Research design, data and methodology: Data were obtained from 618 students at Hanoi University of Industry (HaUI) in Vietnam. The study used structural equation modeling in SPSS and the statistical analysis software AMOS version 24 to explore the information distribution role of Facebook. Results: Findings reveal that subjective norms and social presence play a key role in driving students to use Facebook for studying. In addition, university administrators can boost student satisfaction and academic achievement through Facebook. Interestingly, students who strongly identify with the brand name of the university have a strong connection with the university are more likely to engage in behaviors supportive toward the university. Conclusions: These findings show that Facebook had played a key information distribution role in universities. Thus, the study provides the executive board of the university and teachers can gain new understanding of why students employ Facebook for studying as well as capitalize on the platform to improve several operational metrics such as brand identification, student satisfaction, and academic achievement.
