The purpose of this study is to develop a personality education tea culture therapy program to effectively improve juvenile delinquency prevention and social adaptation. In order to verify the effectiveness of the tea culture therapy program through social intervention, we analyzed whether there were significant differences in the scores of social characteristics such as self-efficacy, self-control, and interpersonal relationships of juvenile detention students before and after participating in the program. Ten juvenile detention students between the ages of 14 and 17 who were accommodated to a juvenile detention center in B city were selected as the experimental group for the study. The tea culture therapy program was conducted 10 times as a social intervention personality education for juvenile delinquents, and as a result, self-efficacy was found to have a pre-mean of 2.37 (SD 0.33) and a post-mean of 2.49 (SD 0.31), showing a significant difference (Z=-5.874. P=.000), self-control showed a significant difference with the pre-mean 2.06 (SD 0.20) and the post-mean of 2.16 (SD 0.19) (Z=-4.743, P=.001). The interpersonal relationship was found to have a significant difference, with a pre-mean of 1.90 (SD 0.32) and a post-mean of 2.15 (SD 0.21) (Z=-5.892, P=.000). The above results show that this program has a significant effect on improving social characteristics such as self-efficacy, self-control, and interpersonal relationships among juvenile detention students. Therefore, the tea culture therapy program developed in this study for personality education for juveniles can be used as a personality education program for various types of adolescents as well as in the field of correctional welfare in the future.

Welding work is a production work method widely used throughout the industry, and various types of welding technologies exist. In addition, many methods are being studied to automate these welding operations using robots, but in the ship manufacturing field, welding such as painting, cutting, and grinding is also the most common operation, but the manual operation ratio is higher than in other industries. Such a high manual labor ratio in the field of ship manufacturing not only causes quality problems and production delays according to the skill of workers, but also causes problems in the supply and demand of manpower. Therefore, this paper analyzed the reason why the automation rate is low in welding work at ship manufacturing sites compared to other industries, and analyzed the production process and field environment for small and medium-sized ship manufacturing companies that repeatedly manufactured with a small quantity production method. Based on the analysis results, it is intended to propose a robot system that can easily move between workplaces and secure uniform welding quality and productivity by collaborating simple welding tasks with humans. Finally, the simulation environment is constructed and analyzed to secure the suitability of robot system application to current production site environment, work process, and productivity, rather than to develop and apply the proposed robot system. Through such pre-simulation and robot system suitability analysis, it is expected to reduce trial and error that may occur in actual field installation and operation, and to improve the possibility of robot application and positive perception of robot system at ship manufacturing sites.

In the event of a disaster occurring within a building, the prompt and efficient evacuation and rescue of occupants within the building becomes the foremost priority to minimize casualties. For the purpose of such rescue operations, it is essential to ascertain the distribution of individuals within the building. Nevertheless, there is a primary dependence on accounts provided by pertinent individuals like building proprietors or security staff, alongside fundamental data encompassing floor dimensions and maximum capacity. Consequently, accurate determination of the number of occupants within the building holds paramount significance in reducing uncertainties at the site and facilitating effective rescue activities during the golden hour. This research introduces a methodology employing computer vision algorithms to count the number of occupants within distinct building locations based on images captured by installed multiple CCTV cameras. The counting methodology consists of three stages: (1) establishing virtual Lines of Interest (LOI) for each camera to construct a multi-camera network environment, (2) detecting and tracking people within the monitoring area using deep learning, and (3) aggregating counts across the multi-camera network. The proposed methodology was validated through experiments conducted in a five-story building with the average accurary of 89.9% and the average MAE of 0.178 and RMSE of 0.339, and the advantages of using multiple cameras for occupant counting were explained. This paper showed the potential of the proposed methodology for more effective and timely disaster management through common surveillance systems by providing prompt occupancy information.

In recent years, the Korean realistic theme of the film momentum gradually rising. Realistic films do not stick to the business and market, and do not simply cater to the audience's needs for watching movies. They reflect social violence and cruel reality, allowing the audience to observe the structural contradictions in reality and think about the direction when watching movies. At the recent cannes film festival, "parasite" won the top prize palm in cannes by an overwhelming margin, with the highest score of 3.3 issues. Although this film is positioned as a thriller with comedy elements, it presents the opposite life images of Korean classes to the audience in a parasitic way, which not only expands the possibility and artistry of realistic film aesthetics, but also enhances the appreciation of the film and gives play to its own aesthetic value. Focusing on the technical and literary nature of the film, and having a high degree of attention to real life, it is an excellent work that tells about class opposition and thinking about reality. This paper considers and analyzes the content, form and creation method of parasite, and discusses the continuous exploration and attempt of realistic film to image language under the demand of market and system, evolving into new aesthetic expression.

For the last several months, abortion debates have sparkled in Korea. The government has escalated the need of active punishment of illegal abortions to solve low fertility problems, while some obstetricians and gynecologist have proclaimed stoppage of illegal abortions suing colleague doctors who has conducted illegal abortions. Women's rights groups and researchers have also responded to the abortion debate claiming that women's decisions over their pregnancy are important in making of abortion policies. To contribute to Korean abortion debates, his paper aims to analyze European experiences of abortion polices in relation to the consequences on women's health. For the analysis of European abortion experiences, three countries - Ireland, U.K, and Netherland -are chosen. These three countries are selected since their legal and social acceptance of abortion and the level of safe abortion system are different. Each country is reviewed by national abortion policy, legal regulation, medical system and the role of civil society. The analysis shows several implications for abortion debates occurring in Korea. Various systematic policy mechanisms - abortion on women' request, abortions without complicated doctor's referrals, transparent and anonymous counseling and information provision regarding abortion, training and education for medical professionals to guarantee high quality abortion, abortions funded publicly for women to improve their access to abortions, steady monitoring and auditing abortion procedures and outcomes for safe abortion and so on - are required in Korean society. Two track procedures - safe abortion on women's request and prevention of unwanted pregnancy - are needed for reproduction of healthy women and society.

This study aimed to evaluate the effects of utilizing educational game content for science learning on science-related attitudes. The content was applied to 24 students in an after-school science club at an elementary school in Gyeongsangbuk-do Province followed by a pre and posttest analysis using the Attitude About the Relevance of Science Test and the Creative Personality Test. This study used Tino's Journey, which was developed by the Korea Creative Content Agency and is currently distributed for free through the Ministry of Education to develop nine lessons that include scientific scenarios and concepts presented in the game. The results demonstrated that science lessons utilizing educational game content significantly influenced the science-related attitudes of the students. Among the subdomains, enjoyment of science lessons increased the most followed by the attitude toward scientific inquiry, social meaning of science, and hobby of science. However, the commonness of scientists, acceptance of scientific attitudes, and career in science did not reveal significant differences. This study classified the students into two groups (i.e., high and low, n=12 each) using the Creative Personality Test in advance. This study performed covariate analysis with the score for pre-science-related attitude as the covariate. Result revealed that the scores for science-related attitude significantly differed between the high and low groups. Specifically, the increase in the scores of the low group was larger than that of the high group. Lastly, the study presented implications for the utilization of educational game content in science learning.

식물체가 건조 스트레스를 받으면 각 기관 물질 생산의 변이, 분화 및 발달 억제를 통해서 식물의 생산활동을 현저히 저하시켜, 식물의 생장, 형태, 개체발생 및 대사생리에 영향을 미치는 것으로 연구되어 왔다. 최근 기후 온난화로 인해 온도가 점진적으로 상승하고 가뭄과 같은 이상기상이 빈번하게 발생함에 따라 많은 노지 작물의 농업 생산성이 약화되고 있다. 배추는 우리나라의 대표적인 식품 중 하나인 김치의 주재료로 연중 안정적인 생산과 공급이 필요시 되지만, 배추의 경우 건조 조건에서 엽육조직의 붕괴와 같은 생리장해가 발생되기 때문에 최근 발생되고 있는 이상 기후의 영향으로 안정적인 생산이 어려워지고 있는 실정이다. 하지만, 배추에서는 이상 기후에 대응이 가능한 내건성 품종의 육성을 위한 연구는 미흡한 실정이다. 따라서 본 연구에서는 내건성이 높은 배추 개발을 위한 기초소재를 찾는 것을 목적으로 농촌진흥청 유전자원센터에서 보존하고 있는 재래종 배추 30계통을 분양받아 강릉원주대학교 생명과학대학 내의 조직배양실을 이용하여 연구를 수행하였다. 배지는 Tissue Culture Square Dish(125×125×20mm)에 Agar를 녹여 40ml씩 분주하여 고체배지를 조성한 후, 건조 처리구 Polyrthylene glycol 6000(PEG) 0%(Control), 20%(Mild Stress), 30%(Severe Stress)를 설정하여 60ml씩 추가 분주하여 배양기 28℃에서 15시간 처리를 하였다. 분양받은 각 계통의 종자는 1% 차아염소산 나트륨으로 10분간 종자표면을 살균한 후, 5번 정도 멸균수로 헹군 후, 표면 살균한 재래종 종자를 고체배지 시험관에 6립씩 치상하였다. 식물체 생육은 각 처리구별 3반복으로 하였으며 주간 12시간 주기, 광도 2,400Lux, 온도 20℃의 조직배양실에서 치상 후 7일간 생육하였다. 치상 후 7일간 생육시킨 식물체를 채취하여 지상부생체중, 지하부 생체중, 뿌리 길이를 측정하였으며, 지상부와 지하부로 나누어 50℃에서 72시간 건조시킨 후, 건물 생산량을 조사하였다. 본 실험 결과 건조 처리(PEG-6000)는 배추의 생장을 저해하였지만, 생육 저해 정도는 계통간의 차이가 있는 것을 관찰할 수 있었으며 무처리구와 스트레스 처리구간의 생장량 변화 정도를 기반으로 군집분석을 수행한 결과 'IT110483'과 'IT104903' 계통이 실험에 공시된 계통들 중 상대적으로 강한 건조 내성을 가진 것을 확인할 수 있었다. 따라서, 재래종 배추 계통 중 일부는 건조내성이 강한 새로운 배추 품종을 육성하는데 있어 유용하게 이용될 수 있을 것으로 사료된다.
