This study aimed to develop a scale to measure the family strength of single-parent families. We analyzed the everyday life and demands of single-parent families using the theory of family strength to draw 78 items that encompass family basis, relationships, roles, social networks and family culture. Using a sample of 286 single-parent families through an online survey platform, we examined the factor structure of the items and selected 48 items based on the results of the factor analysis. Reliability, criterion and construct validity were also examined. The final scale comprised of five domains ; basis, parents' role, work-life balance, social network, lifestyle and household management. This scale can be used as an assessment measure of the family strength of single-parent families for consulting, case management and suggesting various programs in the field. This merit will help enhance the quality of programing for single-parent families at the Healthy Family Support Center and the development of family strength scales for various types of families.

The purpose of this study is to examine the mediating effect of physical activity in the relationship between generalized anxiety disorder and overdependence on smartphones in adolescents. To find a way for solving the problems caused by the over-use of smartphones during adolescence, we tried to find the importance of a health promotion program through physical activities. For the purpose of the study, the 2020 Youth Health Behavior Survey data conducted by the Ministry of Education, the Ministry of Health and Welfare, and the Korea Centers for Disease Control and Prevention were used as analysis data for this study. As a result of the study, firstly, generalized anxiety disorder has a negative (-) relationship with physical activity, and physical activity also has a negative (-) relationship with overdependence on smartphones. Secondly, as a result of analyzing the mediating effect of physical activity in the relationship between generalized anxiety disorder and smartphone overdependence experience, the physical activity was found to be a significant factor. Thirdly, it was confirmed that the physical activity has a partial mediating effect in the relationship between generalized anxiety disorder and smartphone overdependence experience. Increasing physical activity through team sports rather than individual sports may help reduce smartphone use.

Cancer with unlimited cell growth is a leading cause of death globally. Various cancer treatments, including surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy, can be applied alone or in combination depending on the cancer type and stage. New treatments with fewer side effects than previous cancer treatments are continually under development and in demand. Undifferentiated stem cells with unlimited cell growth are gradually changed via cellular differentiation to arrest cell growth. In this study, we reviewed the possibility of treating cancer by using cellular differentiation into the adipocytes in cancer cells. In previous in vitro studies, oral antidiabetic drugs of the thiazolidinedione (TDZ) class, such as rosiglitazone and pioglitazone, were induced into the adipocytes in various cancer cell lines via increased peroxisome proliferator-activated receptor-γ (PPAR γ) expression and glucose uptake, which is the key regulator of adipogenesis and the energy metabolism pathway. The differentiated adipogenic cancer cells treated with TDZ inhibited cell growth and had a less cellulotoxic effect. This adipogenic differentiation treatment suggests a possible chemotherapy option in cancer cells with high and abnormal glucose metabolism levels. However, the effects of the in vivo adipogenic differentiation treatment need to be thoroughly investigated in different types of stem and normal cells with other side effects.

Societal value of the benefits forests provide has grown significantly, given their pivotal role in mitigating climate change and fostering the shift toward a carbon-neutral society. Due to the economic and public value of forests, which extends far beyond landowners and foresters, the forestry sector mutually interacts with society as a whole. Thus, understanding public perceptions and preferences concerning forests and forest policies from the societal viewpoint is vital for shaping future forest policy decisions. This research delved into evolving perceptions over the past 32 years, using a time-series analysis of data gathered from the 'Public awareness survey on forests'. This survey, conducted seven times between 1991 and 2023 by opinion poll agents, provides insights into changing sentiments. The findings reveal a notable increase in public satisfaction with overall forest policies. Specifically, positive sentiments were observed regarding forest rehabilitation, forest trails, education initiatives, and the establishment and functioning of forest recreation facilities. Conversely, the study highlights areas where public satisfaction remained relatively low, notably in matters concerning the use and conversion of mountainous regions, forest disaster prevention, and international forest cooperation. Additionally, the respondents emphasized the need for heightened attention to forest management, the development of forest roads, and increased efforts in overseas afforestation compared to current initiatives.

The purpose of this paper is to examine the concept of trust in Korean culture using the indigenous psychological analysis. First, this paper raises central questions that arise in Korean families, schools, companies and society: 1) Why are some Korean families disintegrating? 2) What core values do Korean schools teach? 3) What are the goals that Korean companies pursue? 4) Does trust exist in Korean society? Second, this paper reviews a series of empirical studies conducted using the indigenous psychology approach. The results indicate the following three major themes: 1) trust is based on relational culture and ingroup identity; 2) emotional attachment and bond provide the basis of trust; 3) the emphasis on cultivation of virtue through constant self-cultivation rather than ability and the control of the environment. Third, this paper raises central issues that need to be addressed: 1) the extension and expansion of trust beyond the narrow confines of the family and ingroup to include outgroup members; 2) recognition and balance of public rationality and private emotions and relations in society; 3) the achievement of balance between self-regulation and the control of the environment.

사회적 기업가정신은 기업가정신 분야의 연구에서 많은 학자와 산업계의 관심을 받고 있는 주제이다. 특히 사회적 기업을 창업하거나 사회적 기업에서 일하고자 하는 사람들은 일반 사람들과 다른 어떤 특성을 가지고 있는지에 대해 선행 연구들은 공감, 도덕적 판단, 지각된 사회적 규범 등의 요소들로 설명하고 있다. 이는 전통적인 기업의 창업자와 비교되며, 사회적 기업가정신에 중요한 선행요소라고 말하고 있다. 그러나 공감능력이 뛰어나고, 공동체에서 사람들과 잘 어울리며, 남을 돕기 좋아하는 사람들이 반드시 사회적 기업가적 의도가 높은 것은 아니며, 이런 특성을 가진 모든 사람들이 사회적 기업에서 일하고자 하는 것은 아니다. 사회적 기업가적 동기에 관한 선행 연구 중에 동기와 행동을 연결하는 복잡한 매커니즘에 대해 설명한 연구는 거의 없는 상황이며, 대부분 공감(Empathy), 사회적 자기 효능감(Social Entrepreneurial Self-Efficacy), 도덕적 의무감 등의 요소를 규명하는데 집중되어 왔다는 한계가 있다. 본 연구는 지금까지 거의 연구되지 않았던 사회적 기업적 의도를 설명하는 타인 지향적 동기(other-oriented motives)와 사회적 기업 직업정체성에 관한 연구이다. 이를 통해 사회적 기업에 참여하려는 개인의 성향을 촉진시키는 요인은 무엇인지를 규명하고자 하였다. 전국 일반고, 특수목적고 및 특성화고등학교와 대안학교 학생 444명을 대상으로 설문조사를 실시하여 타인 지향적 동기요소인 친사회성 동기, 사회적 존재감과 사회적 기업 직업정체성의 관계 분석에 활용하였다. SPSS 26 버전을 활용하여 다중 회귀분석을 실시한 결과 사회적 기업에 대한 직업정체성에 친사회적 동기와 사회적 존재감은 긍정적인 영향을 미치고, 특히 사회적 존재감은 친사회적 동기와 직업정체성과의 관계에 부분 매개효과를 보였다. 결과적으로 역지사지 성향을 가지는 학생일수록 사회적 기업에서 일을 할 의도가 높아지고, 남을 돕고자 하는 의지가 높은 학생, 공동체 의식이 높은 학생일수록 사회적 기업에서 일을 하고자 하는 의지가 높다는 것을 알 수 있었다. 또한 사회적 존재감은 이 과정에서 간접적으로 유의미하게 긍정적인 영향을 미치는 것을 알 수 있었다. 본 연구는 사회적 기업에 대한 직업정체성에 영향을 미치는 선행요인을 규명하고 사회적 기업에 참여하려는 개인의 성향을 촉진하는 요인이 무엇인지 규명했다는 데 의의가 있다. 그리고 이 요인들이 교육을 통해 강화할 수 있으므로 사회적 기업 창업가 육성에 대한 새로운 방향을 제시한다.

This study aimed to investigate the role of student immediacy in learning-related positive affective experiences in the technology-mediated education context. In particular, perceived social presence was expected to mediate the relationship between student immediacy and positive affect. Moreover, we hypothesized the moderating role of technology readiness in the relationship between student immediacy and perceived social presence. To test this hypothesis, a survey of approximately 500 undergraduate students who have attended non-face-to-face online courses was conducted. The results revealed that social presence fully mediated the relationship between immediacy and positive affect. That is, students who scored high on the immediacy scale tended to experience a greater level of social presence during online classes; consequently, they tended to demonstrate more positive affect. As expected, technology readiness moderated the relationship between immediacy and social presence. Unlike previous studies that mainly focused on instructor immediacy, the present study contributed to immediacy literature by empirically testing the positive effect of student immediacy on learning. Furthermore, this study revealed the potential importance of communication competence and its progress in predicting student participation and satisfaction, which could have been changed since the COVID-19 pandemic.

The purpose of this study was to analyze the dietary life units of Korean and American high school home economics textbook according to Habermas's three systems of action and to find out how the three systems of action are reflected in the learning objectives and activity tasks of the textbook. To achieve this purpose, this study analyzed the learning objectives and activity tasks of the dietary life units in the textbooks of 'technology & home economics' and 'home economics science' in Korea, and 'succeeding in life and career' in America using a content analysis technique based on Habermas's three systems of action. In analyzing the content, each learning objective or activity was matched with one of the three systems of action by examining the context. In some cases, two or more systems of actions were integrated in one activity. This is a case where a series of learning tasks that involve different action system were grouped into one. The numbers of learning objectives and activities of the units of 'technology & home economics', 'home economics science' textbooks of Korean high schools and 'succeeding in life and career' dietary life of American high schools were 3, 26, and 248, respectively. In Korean textbooks, the percentage of communicative action was highest among the three systems, that is, 66.7% for 'technology & home economics' textbooks and 50% for 'home economics science' textbooks. In comparison technical action was the highest in American textbooks at 66.5%. Activities related to technical action included cooking, conducting research on health and food, or conducting experiments. The activities related to communicative action included role play related to health and table manners, or writing reports after conducting surveys or interviewing professionals. The activities related to emancipative action were to social participation activities such as service project in relation to health and food, or to find problems that occur in dietary life and think about be best solution through practical reasoning.

Sea surface temperature (SST), which plays an important role in climate change and global environmental change, can be divided into skin sea surface temperature (SSST) observed by satellite infrared sensors and the bulk temperature of sea water (BSST) measured by instruments. As sea surface temperature products distributed by many overseas institutions represent temperatures at different depths, it is essential to understand the relationship between the SSST and the BSST. In this study, we constructed an observation system of infrared radiometer onboard a marine research vessel for the first time in Korea to measure the SSST. The calibration coefficients were prepared by performing the calibration procedure of the radiometer device in the laboratory prior to the shipborne observation. A series of processes were applied to calculate the temperature of the layer of radiance emitted from the sea surface as well as that from the sky. The differences in skin-bulk temperatures were investigated quantitatively and the characteristics of the vertical structure of temperatures in the upper ocean were understood through comparison with Himawari-8 geostationary satellite SSTs. Comparison of the skin-bulk temperature differences illustrated overall differences of about 0.76℃ at Jangmok port in the southern coast and the offshore region of the eastern coast of the Korean Peninsula from 21 April to May 6, 2020. In addition, the root-mean-square error of the skin-bulk temperature differences showed daily variation from 0.6℃ to 0.9℃, with the largest difference of 0.83-0.89℃ at 1-3 KST during the daytime and the smallest difference of 0.59℃ at 15 KST. The bias also revealed clear diurnal variation at a range of 0.47-0.75℃. The difference between the observed skin sea surface temperature and the satellite sea surface temperature showed a mean square error of approximately 0.74℃ and a bias of 0.37℃. The analysis of this study confirmed the difference in the skin-bulk temperatures according to the observation depth. This suggests that further ocean shipborne infrared radiometer observations should be carried out continuously in the offshore regions to understand diurnal variation as well as seasonal variations of the skin-bulk SSTs and their relations to potential causes.
