The present study explored Korean parents' perceptions of and behavior toward game use among teenagers in Korea. A total of 600 Korean mothers of teenagers residing in Seoul and five other metropolitan areas participated in the survey. The survey was constructed based on five categories of variables, including the overall perception of games and game use, specific attitudes toward game use, cognitions about and attitudes toward game addiction, factors predicting parental monitoring of children's game use, and views and opinions about what needs to be done to promote healthy game cultures as well as to prevent problematic game use among teenagers in Korea. Results indicate that the respondents' overall perceptions of and attitudes toward games and game use are negative. In contrast, attitudes toward game use of the respondent's own child are contingent upon various comparison standards. Results also indicate that the respondents tend to overestimate the possibility that their own child is addicted to games, and their perceptions of game addiction are based on a narrow range of behavioral symptoms. Additional analyses indicate that parental monitoring of teenagers' game use can be predicted by the theoretical model driven from Ajzen(1991)'s theory of planned behavior. Finally, results also indicate that, in order to deal with the problems associated with teenagers' game use, proactive approaches to promote healthy game cultures as well as various initiatives to prevent problematic game use are necessary. Implications of the findings and future direction were discussed.

This study aims to fathom the relationship between socio-economic security and social cohesion which are two sub-domains of Social Quality, on the institutional context of welfare state. In order to grasp the institutional context of welfare state, the study adopted welfare status theory and measured socio-economic resources of individuals via the status as welfare beneficiary and welfare taxpayer. The study postulates a theoretical model that the socio-economic security domain affects the social cohesion domain. In order to verity the theoretical hypothesis, this study utilized structural equations analysis(SEM) using social survey data conducted in year 2008. Recognition of social trust was included as the core index of social cohesion, and welfare statuses, socio-economic security and social trust were inserted in the sequence. Results revealed that the amount of resource in regards to welfare status of rights had significant influence on the socio-economic security, whereas it had no significant relations in regards to welfare status of duties. The recognition of socio-economic security derived from status of welfare rights and duties were positively associated with recognition of social trust. Also, the recognition of socio-eocnomic security turned out to have significant influence on social trust. Conclusively, among the two sub-domains of Social Quality, the study found that the socio-economic domain has influence on social cohesion domain. Such results suggest that in order to enhance the overall social cohesion in Korea, more delicate arrangement of welfare institutions are required.

This study analyzed rawinsonde soundings observed during the summer and early fall seasons (June, July, August and September) on the Korean peninsula to examine the utility of the Convective Available Potential Energy (CAPE) and Convective Inhibition (CIN) in predicting the occurrence of deep moist convection and precipitation. Rawinsonde soundings are categorized into two groups based on thermodynamic criteria: high CAPE and low CIN represent a high potential for deep moist convection; low CAPE and high CIN indicate conditions unfavorable for deep convection. A statistical hypothesis test is conducted to determine whether the two groups are significantly different in terms of 12-hour cumulative precipitation, 12-hour mean cloud base, and 12-hour mean mid-level cloud cover. The results, in the case of no-precipitation, reveal statistically significant differences between the two groups, except for the 12-hour mean cloud base during the 21:01-09:00 KST time period. This suggests that the group characterized by high CAPE and low CIN is more conducive to the occurrence of deep moist convection and precipitation than the group with low CAPE and high CIN.

Research, such as developing alternative energy in the transportation field, including aviation, is being actively conducted to solve the issue of current climate change. Interest in ammonia fuel as a carbon free energy (CFE) source is increasing due to the ease of liquefaction and transportation and similarity in energy density to that of methanol. However, explosiveness and toxicity of ammonia make it difficult to handle. Therefore, in this study, stable ammonia production was attempted using relatively easy-to-handle urea water solution (UWS). High temperature steam was used to promote the hydrolysis of ammonia. In order to determine the causes for ammonia production below the theoretical equivalent ratio, it was suggested that there were not enough collisions to promote the hydrolysis based on the kinetic theory of gases. The hydrolysis of unreacted isocyanic acid (HNCO) was tested according to the change in water supply. As a result, an increased amount of ammonia produced was confirmed. The increased amount of ammonia produced in a certain section was dependent on the steam temperature and the flow rate of water supplied.

In the face of complex crises such as a shrinking society, regional imbalance, and climate change, there is a need to seek sustainable development in local communities. In the forest sector, attempts are being made to link forest resources with local industries. However, the current support system, which is centered on the central government, has limitations in achieving sustainable forest management. On the other hand, the international community is actively promoting a shift in systems by introducing the concept of local forestry, which emphasizes local initiatives to achieve sustainable forest management. However, in the Republic of Korea, the concept of local forestry is still unclear, which hinders the promotion of a paradigm shift. In this paper, we applied the Delphi technique to conduct three surveys of 29 academics, administrators, and field experts in the Republic of Korea. The aim was to define the concept of local forestry that is suitable for domestic conditions and identify institutional measures to establish and revitalize it. The results showed that local forestry can be defined as a broad concept that is both consultative and systemic in nature and that an institutional approach that supports actors and their activities is necessary to revitalize local forestry.

This study aims to analyze the complex impact of technological changes in the Fourth Industrial Revolution era and demographic shifts in Korea on military personnel management, and to explore innovative strategies for the Korean military's workforce operations. The research findings indicate that changes in future battlefield environments and the introduction of advanced technologies necessitate a fundamental restructuring of military personnel, emphasizing a shift towards a highly specialized and elite workforce. Key research findings are as follows: First, the military application of cutting-edge technologies, such as unmanned systems, autonomous weapon systems, and AI-based decision support systems, is expanding. Second, this technological advancement requires a restructuring of personnel to foster a technology-intensive elite force, including optimizing troop size, reorganizing unit structures, and increasing the utilization of civilian expertise. Third, strategies for securing high-tech talent include strengthening internal technology talent development programs, establishing systems to attract civilian experts, and building a talent development system through industry-academia-research cooperation. The significance of this study lies in providing a theoretical and practical foundation for building a future-oriented and efficient Korean military organization by presenting innovative measures for military human resource management systems suitable for the Fourth Industrial Revolution era. For these changes to be successfully implemented, cooperation among relevant stakeholders, including the military, government, academia, and industry, is essential, supported by comprehensive national-level planning and support.

Special Practitioner exists based on the need for special fields that are required to manage difficult patients with specialized skills distinguished from General practitioner. The purpose of dental specialist system is to manage patients who are not treatable by general practitioner by training doctors specializing in one specific field, thereby, enhancing health of the public. Oral Medicine deals with orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. In these days, living environments of city life bring about increase in stress which ultimately lead to increase in prevalence of temporomandibular disorder, oral soft tissue disease, neuropathies such as trigeminal neuralgia, and hence, the number of patients seeking help of those symptoms tend to increase. The purpose of this study was to analyze the rate of referrals and the routes of patients seeking help by investigating 3,707 patients who visited Department of Oral Medicine, College of Dentistry, Yonsei University, from August, 2004 to April, 2005. The results were as follows: 1. The types of disease referred to the Department of Oral Medicine were orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. 2. The rate of referrals was 58.51% which implies that more than half of the patients visiting the Department of Oral Medicine were referred. 3. The types of institution which made referrals were analyzed, and as a result, dental clinics made most of the referrals with the rate of 83.23%, while that from medical or oriental medical institutions was 16.78%. 4. Among the patients who visited the Department of Oral Medicine on their own, 30.52% gained the information about the Department of Oral Medicine from internet and mass media, and from neighbors. From the above results, most of the patients visiting the Department of Oral Medicine were found to be referred not only from the field of dentistry but also from the field of medicine. These suggest that Oral Medicine manages patients who are not treatable by general dental practitioners, and medical specialists tend to cooperate with the Department of Oral Medicine to manage diseases associated with Oral Medicine. Therefore, the role of Oral Medicine can be considered to be important as a special field, and the results of this study should be considered when working out a policy of Dental specialist system on demand and supply of residents in the future.

National Competency Standards or NCS is an educational system that emphasizes developing job-related abilities. Therefore it will be an effective solution in training field-oriented work forces if properly applied. However, in the department of social welfare, it is not easy to apply NCS to the curriculum since most academic subjects concerning social welfare focus not on practice but on theory and in addition, most of social welfare departments in junior colleges have an accredited curriculum for the 2nd degree of the social worker qualification. This means it is preposterous if NCS is applied to the curriculum without prior changes in the existing qualification system. So, this paper proposes a draft model to apply NCS to the already-accredited curriculum for the 2nd degree social workers in the junior colleges and details are as follows. Firstly, the competency units will be customized for the existing academic subjects in the curriculum rather than developing new subjects in accordance with NCS competency units. Secondly, some client-related competency units including children, seniors, the disabled are newly developed and then applied to the curriculum, which are crucial for the career development at the junior college level. Thirdly, the competency units are categorized into three types in accordance with the degree of job relevancy - type 1, type 2, type 3. Fourthly, four out of 11 basic job abilities are selected and then developed into academic subjects. Fifthly, all competency units concerning the main job market are regarded as one virtual competency unit and then arranged in the order of type 1s, type 2s and type 3s and then the scope of their study is adjusted to the job abilities required at the main job market.

1957년에 서명된 로마조약(條約)을 처음 개정한 단일(單一)유럽법(法)이 1987년 7월 1일에 발효(發效)되었을 때 유럽공동체(共同體) 12개 회원국(會員國)들은 공동정책(共同政策)에 의거 상업(商業), 농업(農業), 운송(運送), 금융(金融) 및 기타 관련부분에 있어 단일역내시장(單一域內市場)을 형성하기로 약속했다. 물론 완전한 역내공동시장(域內共同市場)은 자유로운 운송시장(運送市場)을 전제로 한다. 따라서 EC조약(條約)은 모든 회원국(會員國)들이 서어비스의 자유에 근거하여 공동운송정책(共同運送政策)을 따를 것을 강제하고 있다. 항공운송(航空運送)에 있어서의 목표도 역시 다른 모든 경제활동의 목표와 마찬가지로 로마조약(條約)이 적용되는 공동운송정책(共同運送政策)의 일부를 구성하고 있다. 종합적인 공동체항공정책(共同體航空政策)의 작업에는 운임(運賃), 공급량(供給量), 시장진출(市場進出) 및 경쟁상(競爭上)의 일괄적인 자유화 조치 이상의 것을 내포하고 있다. 그것은 국가장벽으로 방해되지 않는 공동체(共同體)의 항공운송망(航空運送網)의 개발과 확장뿐만 아니라 경제(經濟), 안전(安全), 환경(環境) 및 사회적(社會的) 요인(要因)들 간에 합리적인 균형을 이루는 공동체항공운송정책(共同體航空運送政策)의 개발을 위한 공동항공운송정책(共同航空運送政策)의 공식화(公式化)를 요한다. 1987년의 항공(航空)에 관한 일괄입법조치, 1989년의 제 2 차 항공(航空)에 관한 일괄입법조치 및 1992년 이후로 예정된 제 3 차 일괄입법조치에 따라 EC는 초국가적(超國家的)인 항공운송(航空運送) 분야에 있어서의 개방적인 국제경쟁(國際競爭)을 본격적으로 추구하고 있다. 결국 이러한 일괄규칙은 EC와 제(第) 3 국(國)들간의 관계에 중대한 의미를 가지게 될 것이다. EC항공운송정책(航空運送政策)이 아시아 항공산업(航空産業)의 상업운선(商業運船)에 어떠한 영향을 미칠 것인가는 모든 아시아 국가들이 알아야 할 중요한 문제이다. 이론적으로 말해서, 역내공동체(域內共同體) 항공운송(航空運送)의 자유화는 아시아 국가들에 대한 치외법권적(治外法權的) 효과를 일으킬 수 있는 로마조약(條約)과 유럽사법재판소(司法裁判所)에 의해 형성된 원칙들에 필연적으로 영향을 미칠 것이다. 이와 관련하여 아시아 항공산업(航空産業)은 무차별원칙(無差別原則), 설립(設立)의 자유(自由), 서어비스의 자유(自由) 및 EEC 경쟁법(競爭法)과 같은 제(第) 3 국(國)의 국제항공운송에 영향을 미치는 일련의 새로운 원칙과 법률의 출현에 큰 관심을 갖고 있다. 실무적인 관점에서, 1992년 이후의 종합적인 공동체항공운송정책(共同體航空運送政策)의 작업에는 항공운화(航空運貨), 시장진출(市場進出), 제(第)3 및 제(第)4의 운륜자유권(運輪自由權), 복수지정(複數指定), 제(第)5의 자유(自由), 캐보타지(cabotage), 손상(損傷)(derogation), 공급량(供給量), 편수(便數), 불정기운항(不定期運航) 및 기타 부문항공기소음(部門航空機騷音), 최저(最低) 안전(安全) 및 사회적(社會的) 조치(措置), 항공종사자면허(航空從事者免許), 감항증명(堪航證明), 운항시간제도(運航時間制度), 컴퓨터 예약제도(豫約制度), 탑승거절보상의 공동최저기준(共同最低基準), 공중혼잡(空中混雜), 공항이착륙시간할당법(空港離着陸時間割當法), 공항시설(空港施設), 정부지원(政府支援 등). 이와 같은 모든 공동체항공운송정책(共同體航空運送政策)의 주요문제들은 아시아 항공산업(航空産業)에 여러 각도로 영향을 미치게 될 것이다. 위와 같은 문제들 가운데, 제(第) 3국(國) 항공사(航空社)들의 역내공동체(域內共同體) 항로(航路)의 접근, 공급량(供給量), 운임(運賃), 제(第)5의 자유(自由) 및 캐보타지가 아시아 항공산업(航空産業)에 관심이 큰 문제가 되고 있다. 아시아 항공사(航空社)들의 EEC시장(市場)에로의 상업운항(商業運航)이 다소 영향을 받게 될 것이다. 첫째, 복수(複數) 목적지(目的地) 문제이다. 둘째, 항공(航空)서어비스의 운임(運賃) 및 료솔(料率)문제이다. 셋째, 항공운송구역(航空運送區域)에서의 사업에 대한 경쟁원칙의 적용 문제이다. 넷째, 제(第)5 자유(自由) 운륜권(運輪權) 문제이다. 다섯째, 캐보타지(cabotage)문제이다. 끝으로, 유럽 항공사(航空社)들간의 합병(合倂)의 문제이다. 결론적으로 유럽공동체항공운송(共同體航空運送)의 자유화는 1993년까지 공동체(共同體) 역내(域內)와 역외(域外)의 항공운송법제(航空運送法制)의 현재의 모습을 극적으로 바꾸어 놓을 정도로 가속화(加速化)되고 있다. 한편 항공운송(航空運送)의 자유화(自由化)에 대한 EC의 제의는 대담하고 급진적이다. 반면에 그것이 아시아 항공산업(航空産業)에 미칠 영향 또한 중대하다. 의심할 여지없이 항공사(航空社)와 고객들의 이익면에서 EEC와 비(非)EEC국가들의 항공운송산업(航空運送産業)에서 더욱 경제적으로 경쟁적이 되도록 할 필요가 있다. 전세계 항공운송산업(航空運送産業) 운영(運營)의 대부분을 정부가 소유하거나 통제하는 것은 정말로 국제항공운송(國際航空運送)의 발전에 불필요한 장애를 일으킨다. 따라서 國內航空社와 전세계 항공사(航空社)들간의 이해관계의 조화를 협상하는 것이 중요하다. 아마도 아시아 항공사(航空社)들간의 지역적 협조가 미국(美國)뿐만 아니라 유럽으로 부터의 압력 증가에 대해 균형을 이루는 힘이 될 수 있을 것이다.

In this study, the landscape of Insa-dong was interpreted from the viewpoint of a social construction of landscape, which regards the dynamic process of landscape change as more important than landscape visibility. This viewpoint also regards landscape as the result of its interaction with certain actors. From a review of previous studies on the same subject, it was found that the physical environment, institutions, and images are essential factors influencing landscape change. Insa-dong, which was Kwanindaing and Daesadong during the Joseon Dynasty, acquired symbolic meaning as a traditional area during the Japanese colonial period because of its many antique shops and Korean-style buildings. In 1970, the establishment of modern galleries in the district added to its image as a haven of the traditional Korean culture. Insa-dong thus eventually came to be referred to as "the street of traditional culture" by the people of Korea. Thanks to global festivals like the Asian Games, the Olympics, and the World Cup, Insa-dong's reputation as a cultural tourist destination has become stronger as these festivals created a need for a place in Korea where the country's traditional culture can be showcased to foreign tourists. After the mid-1990s, the merchants of Insa-dong began to cash in on the district's image as a showcase of traditional Korean culture due to the economic depression that emerged then. The people of Insa-dong and those outside it, however, came to feel that this trend damaged the district's image. Therefore, the people of Insa-dong and the district's local government started a movement to restore the aesthetic value and symbolic meaning of the district's landscape. This effort induced institutional change. Insa-dong used to be a natural haven of traditional Korean culture. Its landscape has recently been reconstructed so that this image could be restored. This process was made possible by the active interaction of diverse people: merchants, users, administrators, and NGOs.
