The purpose of this study is to investigate the influences of Science Core schools on students' positive experiences about science (PES) through in-depth interviews with teachers in charge of science core schools. In-depth interviews with teachers were conducted to explore the factors that led to the effectiveness of science core schools in improving the student's PES in light of operational characteristics of science core schools as leading schools, characteristic factors of science core schools on students PES, and improvement plans and requirements of science core schools as leading schools, as well as implications for general high schools. In the case of science core schools, the teacher's enthusiasm for science teaching encouraged students' participation in science classes, promoted students' interest in science other than science-core classes, improved students' inquiry and research skills, increased students' competencies such as communications and collaboration by improving science instructions, and affected career search and exploration based on interests in science experiences. Based on the results, ways to spread the characteristics of science core schools to general schools' curriculum implementation are suggested including providing opportunities to experience the value of science study, to experience science and engineering careers through senior students, to participate in team projects and self-regulated science inquires, and so on.

This study is a hermeneutic phenomenological study on the experiences of 10 beginning science teachers who have been building positive or negative identity as teachers for the first 3 months. This study was conducted by four steps of the phenomenological qualitative research process suggested by Yeu (2015) based on the study of hermeneutic phenomenology suggested by van Manen (1990). The main data of this study is the transcription data of the telephone interviews collected in consideration of the working area of the research subjects. The main theme is found by categorizing and conceptualizing the meaning of the phenomenon revealed in the data and the process of confirming the legitimacy of the main theme. The results of this study show that the experiences of beginning science teachers that could affect their positive identity as teachers have common moments when they realize that 'I am a necessary person for someone'. On the other hand, the teachers create negative teacher identity when they doubt their teaching competency, particularly when they are not confident about their attitudes toward students or when they are unable to engage students actively in lessons. The results of this study provide important implications for pre-service science teacher preparation program in Korea.

The AI speaker market is growing steadily. However, the satisfaction of actual users is only 42%. Therefore, in this paper, we collected reviews on Amazon Echo Dot 3rd and 4th generation models to analyze what hinders the user experience through the topic changes and emotional changes of each generation of AI speakers. By using topic modeling analysis techniques, we found changes in topics and topics that make up reviews for each generation, and examined how user sentiment on topics changed according to generation through deep learning-based sentiment analysis. As a result of topic modeling, five topics were derived for each generation. In the case of the 3rd generation, the topic representing general features of the speaker acted as a positive factor for the product, while user convenience features acted as negative factor. Conversely, in the 4^th generation, general features were negatively, and convenience features were positively derived. This analysis is significant in that it can present analysis results that take into account not only lexical features but also contextual features of the entire sentence in terms of methodology.

In the East Sea of Korea the vertical structure functions of the temperature field were evaluated and the characteristic thermal zone was classified by the use of the empirical orthogonal function(EOF) method. The East Sea of Korea within the hydrographic lines of 10-107 of the Fisheries Research and Development Agency of Korea(FRDA) can be divided into three thermal regions by the characteristics of the vertical temperature variability. They are the North Korean Cold Current(NKCC) region near the coast which extends parallel to the north-south direction, the Warm-Core(WC) region which dominates almost all the hydrographic stations of the Line 104 of the FRDA and occupies a few stations of the Line-103 and -105 with its axis at the Line 104, and the East Korea Warm Current(EKWC) region which is bisected into the northern and the southern part by the WC region, respectively. Considering the two most important modes, $85.20-98.20\%$ of the total variance of temperature variation are explained in the NKCC region, $85.20-92.90\%$ in the EKWC region, and$85.50-91.70\%$ in the WC region. The first mode has its peak value at the surface with the annual cycle of variation. The spatial pattern of the first mode portrays a coherent vertical variation in the EKWC region and a clear anti-correlation both in the NKCC region and in the WC region where the zero-crossing depths are loom and 200m, respectively. The second mode of the NKCC region is particularly noticeable, haying its peak at loom with coherent vertical variation. To study the time dependency of the vertical structure functions, the extended EOF(EEOF) method was used. The persistence of the first mode is less than 4 months in the study area. The annual variation of the first mode in the NKCC region is different from those in the WC region and in the EKWC region.

Objective: This study examined the gossip, an evaluative conversation about an absent third party, through qualitative research methods, and explored the subjects and the social function of gossip among young children. Methods: The subject of this study included 24 five-year-olds children in Somang class at Baram kindergarten in Seoul. The data consisted of 20 participant observation, 2 in-depth interviews with the teacher, and informal interviews with the children. Results: The subjects of gossip among young children were peers, teachers, and family members. The social function of gossip among children was strengthening peer relationship, selecting peers, confirming rules, and pleasure. The results of this study confirmed that children are sensitive observers of their surroundings and that their peers, teachers, and families are important beings with influence in their lives. It also showed that children's gossip was a social conversation in which children build peer relationships, learn norms and experience pleasant emotions. Conclusion/Implications: This study has the significance of providing various perspectives on the socialization process of young children by looking at gossip which was perceived as a negative image, from a new perspective.

본 논문은 척담(滌痰) 축어(逐瘀) 고본(固本)의 방법으로 천식을 완화시킨 치험에 관한 내용이다. 천식의 병인병기는 폐(肺) 비(脾) 신(腎) 삼장(三臟)의 본허(本虛)로 인한 알레르기성 체질이 내적인 근본요인으로 간주된다. 담어복폐(談瘀伏肺)는 천식의 병리적인 결과로서 증상유발의 요인이기도 하다. 즉 담어(痰瘀)는 천식의 병리적인 부산물이며, 동시에 천식을 일으키는 치병요인이 된다. 담어(痰瘀)가 내복(內伏)하여 철저히 제거되지 않으면 천식은 결코 완치될 수 없다. 이와 같은 한의학적인 관점은 현대의학에서 천식을 기도의 만성 염증에 의하여 유발된 증상으로 파악하고 있는 기전과 일맥상통하다. 또한 담(痰) 어(瘀) 허(虛)는 천식의 병리변화 과정에서 전반적으로 영향을 미치고 있다는 인식이 지배적이며, 이는 천식치료를 위한 처방구성에 이론적 근거를 제시하고 있다. 치료: 천식은 발작기와 완화기로 분류하여 치료하며, 발작기는 냉효(冷哮)와 열효(熱哮)로 구분된다. 냉효(冷哮)의 경우 치료원칙은 온폐산한(溫肺散寒), 척담평천(滌痰平喘), 화어행체(化瘀行滯)를 기본으로 한다. 처방은 구마황(灸麻黃) 행인(杏仁) 황금(黃芩) 세신(細辛) 계지(桂枝) 오미자(五味子) 당귀(當歸) 울김(鬱金) 목단피(牧丹皮) 지룡(地龍) 정력자(?歷子) 담남성(膽南星) 황기(黃?) 감초(甘草) 등을 기본적으로 사용한다. 열효(熱哮)의 경우 치료원칙은 청열사폐(淸熱瀉肺) 척담평천(滌痰平喘), 화어행체(化瘀行滯)를 근본으로 삼고, 처방으로는 구마황(灸麻黃) 행인(杏仁) 황금(黃芩) 목단피(牧丹皮) 적작약(赤芍藥) 당귀(當歸) 정력자(?歷子) 담남성(膽南星) 지룡(地龍) 어성초(魚腥草) 포공영(蒲公英) 황기(黃?) 감초(甘草) 등을 기본적으로 사용한다. 완화단계도 역시 두가지 유형으로 나누어지는데, 폐신음허형(肺腎陰虛型)은 익기양음(益氣養陰) 척담행어(滌痰行瘀)를 치료원칙으로 하고, 처방에는 남북사삼(南北沙蔘) 구자울(灸紫?) 및 관동화(款冬花) 당귀(當歸) 목단피(牧丹皮) 울김(鬱金) 정력자(?歷子) 세신(細辛) 오미자(五味子) 구기자(枸杞子) 산수황육(山茱黃肉) 황기(黃?) 감초(甘草) 등을 기본적으로 사용한다. 비신양허형(脾腎陽虛型)은 온보비신(溫補脾腎) 화어척담(化瘀滌痰)을 원칙으로 하며, 처방에는 구마황( 灸麻黃) 세신(細辛) 오미자(五味子) 당귀(當歸) 단삼(丹蔘) 울김(鬱金) 정력자(?歷子) 반하(半夏) 보골지(補骨脂) 선령비(仙靈脾) 태자삼(太子蔘) 황기(黃?) 감초(甘草) 등을 기본적으로 사용한다. 치험(治驗): (1) 천식의 실증(實證)은 치료를 한 뒤 완화단계에 접어들면서 허증(虛證)으로 전화되는데, 허천(虛喘)도 역시 천식이니 만큼 단순히 보법(補法)만 사용하여서는 안된다. 시종일관 천식치료에는 척담화어(滌痰化瘀)의 원칙을 지켜야 한다. 폐내(肺內)의 담어(痰瘀)가 철저하게 제거되어야 폐(肺)의 순환기능을 개선시켜 기도(氣道)의 염증을 신속히 흡수하고 치유할 수 있다. 이와 같은 치료과정은 약 3-6개월이 필요하다. 완화단계의 기간이 길어질수록 완치될 확률도 높아진다. (2) 급성기 천식은 폐(肺)를 다스려야 한다. 폐(肺)를 다스리는 방법에는 선폐(宣肺), 청폐(淸肺), 온폐(溫肺), 윤폐(潤肺) 및 척담거어(滌痰祛瘀) 등이 있다. (3) 증상이 완화되면 신(腎)을 다스린다. 천식은 신허(腎虛)가 근본적인 원인이므로 완화단계에서 심지어 발작기에도 보신제(補腎劑)를 추가하여 사용하면 배의 효과를 얻을 수 있다. (4) 비(脾)의 기능을 강화하여 근본을 채우는 부비배본(扶脾培本)도 중요하다. 후천의 수곡정미(水穀精微)로 선천을 충족시키고 자양하는 것은 질병에 대한 저항력을 키우고 재발을 경감시키거나 방지하는 효과를 기대할 수 있으므로 역시 천식치료의 중요한 방법 중 하나이다.

This study aims to understand the characteristics of Korean language learners and propose appropriate teaching plans for them through a focus group interview with Korean language instructors who had experience in teaching Korean at university-attached institutions in Hong Kong. For this purpose, the investigator interviewed ten instructors who taught Korean for at least five years. Korean language learners in Hong Kong who were in their twenties, but there were diverse age groups, including those in their fifties or older. Their motivations for learning Korean included the Korean Wave and the influence of support from the Continuing Education Fund by the Hong Kong government. Korean language learners in Hong Kong were characterized by active learning desire and effort, continuous learning intention, passive performance in speaking, and sensitivity to the disclosure of private information. Based on these findings, the study proposes to devise teaching and learning methods based on various age groups in a class and teaching methods for speaking that reflect the characteristics of Korean language learners in Hong Kong to teach Korean more effectively. The study is significant as a field study that examines the learning motivations, learning attitudes, and difficulties with Korean study of Korean language learners based on an unprecedented survey of the characteristics of common local Korean learners in Hong Kong.

In March 2020, as it was declared a COVID-19 pandemic, various quarantine measures were taken. Accordingly, many changes have occurred in the tourism and hospitality industries. In particular, quarantine guidelines, such as the introduction of non-face-to-face services and social distancing, were implemented in the restaurant industry. For decades, research on restaurant attributes has emphasized the importance of three attributes: atmosphere, service quality, and food quality. Nevertheless, to the best of our knowledge, research on restaurant attributes considering the COVID-19 situation is insufficient. To respond to this call, this study attempted an exploratory approach to classify new restaurant attributes based on understanding environmental changes. This study considered 31,115 online reviews registered in Naverplace as an analysis unit, with 475 general restaurants located in Euljiro, Seoul. Further, we attempted to classify restaurant attributes by clustering words within online reviews through TF-IDF and LDA topic modeling techniques. As a result of the analysis, the factors of "prevention of infectious diseases" were derived as new attributes of restaurants in the context of COVID-19 situations, along with the atmosphere, service quality, and food quality. This study is of academic significance by expanding the literature of existing restaurant attributes in that it categorized the three attributes presented by existing restaurant attributes and further presented new attributes. Moreover, the analysis results have led to the formulation of practical recommendations, considering both the operational aspects of restaurants and policy implications.
