Objectives : The purpose of this study was to examine structural abnormalities of brain in patients with pathological gambling(PG) using voxel-based morphometry. Methods : We compared gray matter(GM) volumes between 10 patients with PG and 14 age- and IQ-matched healthy controls and examined the relationship of GM volumes with clinical variables in patients with PG. Results : We found significant increase of GM volume in the superior, middle, and inferior frontal gyri, the midbrain, the middle temporal gyrus, the precuneus, and the fusiform gyrus of patients with PG. A significant decrease of GM volume was observed in the parahippocampal gyrus and the lingual gyrus of the patient group. In addition, GM volumes in some of these regions were positively associated with South Oaks Gambling Screen score and negatively with age of onset in patients with PG. Conclusion : Current findings indicate that structural abnormalities in the fronto-temporal cortex, the midbrain, and the precuneus might be involved in the pathophysiology of PG, and contribute to some of the behavioral changes observed in patients with PG.

중국 철강산업의 정책추이 분석

최정석(CHOI JUNG SEOK),최준환(Choi, Joon Hwan) 한국중국문화학회 2022 中國學論叢 Vol.- No.73

2020년 시진핑 주석의 탄소중립 선언을 기점으로 탄소배출이 많은 석탄 및 철강산업은 모든 정책에서 우선순위로 주목을 받기 시작하였다. 이에 본 논문에서는 2020년을 기점으로 전후로 나누어 주요 철강산업정책을 문헌을 토대로 정리하고 분석하였다. 우선 2020년 이전의 철강산업정책의 주요흐름을 살펴보면, 중국 철강산업은 1996년 세계 조강생산량 1위를 차지한 이후, 양적으로는 급속한 성장을 이어오고 있지만, 기술수준은 국제 선진수준에 비해 질적으로 차이가 있기 때문에 향후 발전의 중점은 기술업그레이드와 구조조정에 둘 것을 강조하며 산업정책과 문건들을 반포하였다. 다만 고질적인 문제점들을 변화시키려고 했지만, 한계에 봉착하는 모습들을 보여 2015년 기존 수요측면에서의 구조조정이 아닌 공급측면에서의 구조조정인 공급측개혁을 실시한 것으로 보여진다. 다음으로 2020년 이후 발표된 철강산업정책 및 문건들을 보면, 지속적인 지방정부의 생산량 억제 및 노후된 생산시설 업그레이드, 친환경 등에 중점을 두고 시행하였다. 과거 중국정부가 제기한 철강산업의 구조조정 외에도 최근에는 스마트 철강 및 철강생산의 탄소배출감소 등 친환경 철강산업 발전을 위해 대내외적으로 강조하였다. 또한 철강제품의 고부가가치 상품생산을 통한 국제경쟁력을 제고하기 위해, 각 지방정부에서 노후된 생산시설 폐쇄 및 업그레이드 정책들을 추진 중이다. 중국 철강산업은 과거 중국경제 양적성장을 대표하는 산업에서 2021년 중국정부의 철강산업정책의 패러다임 변화로 인해 향후 질적성장을 대표하는 산업이 될지는 지켜봐야 되겠지만, 확실한 부분은 과거 탄소배출을 중시하지 않으며 중국경제 성장을 이끌어왔던 모습에서 앞으로는 우선적으로 철강생산량 감축을 통해 친환경적인 부분에서부터 변화가 올 것으로 판단된다. After President Xi Jinping announced in 2020 to achieve carbon neutrality, the coal and steel industries with high carbon emissions began to receive policy attention. Therefore, this article takes around 2020 as the starting point, and based on the literature, sorts out and analyzes the main policies of the steel industry. First of all, from the perspective of the mainstream of steel industry policy before 2020, China s steel industry has been ranking first in the world s crude steel output since 1996, and the number has continued to grow rapidly, but there is a qualitative gap between the technical level and the international advanced level. Therefore, the introduction of It also formulated industrial policies and documents, emphasizing that the focus of future development should be on technological upgrading and structural adjustment. However, they are trying to change long-standing problems, but they have reached the limit, so it seems that in 2015, supply-side reforms, supply-side structural adjustment, rather than the existing demand-side structural adjustment, were implemented. Secondly, judging from the steel industry policies and documents announced after 2020, the focus of implementation is that local governments continue to suppress production, upgrade and transform outdated production facilities, and be eco-friendly. In addition to the structural adjustment of the steel industry proposed by the Chinese government in the past, the recent focus at home and abroad has been on the development of an eco-friendly steel industry such as smart steel and carbon reduction in steel production. In addition, in order to improve international competitiveness by producing high value-added products of steel products, local governments are promoting policies to close and upgrade outdated production facilities. As the Chinese government s steel industry policy in 2021 undergoes a paradigm shift from an industry that represented quantitative growth in China s economy in the past, it remains to be seen whether China s steel industry will become an industry that represents qualitative growth in the future. From the perspective of driving economic growth, the changes will first come from the environmental protection part of the reduction in steel production. 2020年习近平主席宣布实现碳中和后,碳排放高的煤炭和钢铁行业开始受到政策的重视。 因此本文以2020年前后为切入点,以文献为基础,对钢铁行业的主要政策进行了梳理和分析。 首先,从2020年前钢铁产业政策的主流来看,中国钢铁工业自1996年位居世界粗钢产量第一以来,数量持续快速增长,但技术水平与国际先进水平有质的差距层面因此,出台了产业政策和文件,强调未来发展的重点应该放在技术升级和结构调整上。然而,他们试图改变长期存在的问题,但他们已经到了极限,所以似乎在2015年实施了供给侧改革,即供给侧结构调整,而不是现有的需求侧结构结构调整。 其次,从2020年以后公布的钢铁产业政策和文件来看,实施的重点是地方政府持续抑制生产、落后生产设施升级改造、生态友好。除了中国政府过去提出的钢铁行业结构调整外,近期国内外都将重点放在了智能钢铁和钢铁生产减碳等生态友好型钢铁行业的发展上。此外,为了通过生产钢铁产品的高附加值产品来提高国际竞争力,各地政府都在推动关闭和升级落后生产设施的政策。 由于2021年中国政府的&

최정석 ( Choi Jung Seok ),최석규 ( Choi Seok Gyu ) 한중사회과학학회 2022 한중사회과학연구 Vol.20 No.4

본 연구는 중국 이주노동자의 공동체이식이 문화적응스트레스에 어떤 영향을 미치는지를 구체적으로 확인하는데 연구의 목적을 두었다. 본 연구의 결과는 이론적 근거와 선행연구를 제시한 공동체의식에 따라 문화적응스트레스에 선행조건이 된다는 사실을 확인하였다. 이에, 중국 이주노동자들의 스트레스를 낮추기 위해서 중국출신 이주노동자들의 공동체의식 수준을 높이기 위한 시사점을 제시하였다. 주요결과는 다음과 같다. 첫째, 중국 이주노동자들의 인구학적 변인들과 공동체의식, 문화적응스트레스와의 차이검증을 위해 t-검증 및 ANOVA 분석을 실시한 결과, 중국 이주노동자의 문화적응스트레스와 한국어수준에서 유의미한 차이를 보였다. 한국어 레벨이 없는 근로자는 한국어수준이 높은 근로자보다 스트레스 수준이 높음을 알 수 있었다. 둘째, 공동체의식 하위요인인 Membership, Influence, Reinforcement of Needs, Shared Emotional Connection과 문화적응스트레스와의 상관관계를 확인하기 위해 상관분석을 실시한 결과, 하위요인별 상관관계에서는 공동체의식 하위요인인 Influence(r=-.518, p<0.01)과 문화적응스트레스는 부(-)의 상관을 보였다. 셋째, 인구학적변인과 공동체의식에 미치는 영향력을 확인하기 위해 위계적 회귀분석을 실시한 결과, 인구사회학적 요인을 포함한 모형1에서는 문화적응스트레스에 통계적으로 유의한 영향을 미쳤다. 본 연구는 한국사회 내에서 이주노동자의 공동체의식과 문화적응스트레스와의 관계를 연구하여 기존 연구와 이론적 및 실무적인 측면에서 의미를 부여하였다. 향후 연구에서는 지역별 특성, 가족관계, 모국가족과의 관계, 주변환경, 개인의 다양한 특성, 사회 인지적 요인, 심리적 경향을 파악하여 공동체의식과 스트레스에 미치는 요인들을 구체적으로 분석해볼 필요가 있다. The purpose of this study was to confirm in detail how the community transplantation of Chinese migrant workers affects the acculturation stress. The results of this study confirmed the fact that acculturation stress is a prerequisite according to the theoretical basis and the sense of community that suggested previous studies. Accordingly, in order to reduce the stress of migrant workers in China, implications for raising the level of community consciousness of migrant workers from China were presented. The main results are as follows. First, as a result of t-test and ANOVA analysis to verify the differences between the demographic variables, community consciousness, and acculturation stress of Chinese migrant workers, there was a significant difference in acculturation stress and Korean level of Chinese migrant workers. It was found that workers without a Korean level had a higher level of stress than workers with a high level of Korean. Second, the correlation analysis was conducted to confirm the correlation between the sub-factors of community consciousness, Membership, Influence, Reinforcement of Needs, Shared Emotional Connection, and acculturation stress. =.518, p<0.01) and acculturation stress showed a negative (-) correlation. Third, as a result of hierarchical regression analysis to confirm the influence of demographic variables and community consciousness, model 1 including demographic factors had a statistically significant effect on acculturation stress. In this study, the relationship between migrant workers’ sense of community and cultural adaptation stress in Korean society was studied, and meaning was given in terms of theoretical and practical aspects as well as existing studies. In future research, it is necessary to analyze the factors affecting the sense of community and stress in detail by identifying regional characteristics, family relations, relations with family members in the home country, surrounding environment, various characteristics of individuals, social cognitive factors, and psychological tendencies.

최정석 ( Choi Jung Seok ),최준환 ( Choi Joon Hwan ) 국민대학교 중국지식네트워크 2019 중국지식네트워크 Vol.14 No.-

본 연구에서는 한국인을 포함한 외국인이 중국으로 취업을 하는데 있어 가장 중요하다고 볼 수 있는 중국의 외국인 인력정책, 사회보장제도, 비자제도 등 3가지를 중심으로 살펴보았다. 분석결과를 토대로 시사점을 제시하면 다음과 같다. 첫째, 외국인 인력정책 측면에서 보면, 외국인 취업허가제도의 핵심은 중국에서 이미 취업했거나, 신규 취업하는 외국인을 외국인 고급인재(A), 외국인 전문인재(B), 외국인 일반인력(C) 등 3가지 유형으로 구분하여 기준에 따라 분류 관리함을 알 수 있었다. 둘째, 사회보장제도 측면에서 보면, 2013년 1월 16일부터 발효된 “한-중 사회보험협정”은 중국에서 일하는 한국인 근로자에 대해 사회보험료 이중부담을 면제해주기 위해 체결된 양자 간 조약으로 일하는 나라의 해당 사회보험 적용이 각각 28%, 3%가 면제되기 때문에, 과거 이중으로 부담된 비용을 경감할 수 있는 긍정적인 효과를 볼 수 있게 되었다. 셋째, 비자제도 측면에서 보면, ‘외국인 출입국 관리조례’에 따르면 기존의 비자유형에 기초하여 F비자는 F비자와 M비자(무역비자)로, L비자는 L비자, Q비자(가족방문비자), S비자(개인사무비자)로 분할했고, 해외 우수인재의 영입과 중국 지식산업의 발전을 위하여 R비자(인재비자)를 신설하여 보통비자의 유형을 기존 8가지에서 12가지로 확대하였다. In this study, we focused on the three most important factors for foreigners, including Koreans, to work in China, namely, China's foreigner manpower policy, social security system, and visa system. Based on the results of analysis, suggestions are as follows. First, from the viewpoint of foreigner manpower policy, the core of the foreigner work permit system is three types of foreigners who have already worked or newly employed in China, including foreign advanced manpower (A), foreign manpower manpower (B) Type, and classified according to the criteria. Second, in terms of social security systems, the "Korea-China Social Insurance Agreement", which came into force on January 16, 2013, is a bilateral treaty concluded to exempt the Korean workers in China from the double burden of social insurance premiums. Of their social insurance coverage is exempted by 28% and 3%, respectively, so that they can see the positive effect of reducing the cost burdened in the past. Third, in terms of the visa system, according to the 'Immigration Control Act for Foreigners', based on the existing visa type, the F visa is for F visa and M visa (trade visa), L visa is L visa, Q visa ), And S visa (personal office visa). In order to recruit talented foreign talent and to develop the Chinese knowledge industry, R visas were newly created, expanding the usual visa types from 12 to 12 types.

Specifically, the analysis results are as follows. First of all, in terms of influence coefficient, the fact that specialized equipment manufacturing and metering/instrument manufacturing were ranked at the top in 2012 indicates that the supply-side reform implemented by the Chinese government is achieving some effectiveness, and the transition from traditional manufacturing, which was responsible for quantitative growth in the past It can be seen that progress is being made towards qualitative growth. In addition, it can be analyzed that it had an impact on the IT manufacturing industry, where technology and expertise were added, under the influence of government policies such as specialized equipment manufacturing industry, other manufacturing industry, and measurement/measurement manufacturing industry. Second, in terms of sensitivity coefficient, it can be seen that most of the high-ranking industries in 2012 were traditional manufacturing industries that made a great contribution to China"s economic development. These industries can be seen as the main targets of the supply-side reform implemented by the Chinese government. It is worth noting, however, that the wholesale and retail industry, along with the traditional manufacturing industry, influenced the growth of the wholesale and retail industry through various domestic demand stimulus support policies implemented to overcome the short-term internal and external economic crisis, and furthermore, the steel industry. It can be seen that the industry has been affected.

니코틴 의존의 뇌 기전 및 약물 치료

최정석(Jung-Seok Choi) 한국중독정신의학회 2015 중독정신의학 Vol.19 No.1

Cigarette smoking causes high rates of mortality and morbidity. Despite the efforts of many individuals to quit smoking, maintenance of long-term abstinence is difficult. Understanding the neural mechanisms of nicotine dependence is essential for the development of effective medications to maintain smokers’ abstinence. Nicotine may exert its motivational effects through direct actions on nicotinic acetylcholine receptors (nAchRs) containing the β2 subunit, located on dopamine neurons. Nicotine also modulates dopamine release indirectly by binding to nAchRs located on the excitatory glutamatergic and inhibitory γ-aminobutyric acid (GABA) neurons in the ventral teg-mental area. The initiation and maintenance of nicotine dependence usually occurs through positive/negative reinforcements, conditioning to various smoking cues, habituation/automatized processes, dysfunctional inhibitory systems, and neuroadaptations in the function of dopamine, glutamate, and GABA. Pharmacotherapies including varenicline, bupropion, or baclofen could facilitate smoking cessation via distinct neurobiological mechanisms of action. The appropriate use of pharmacotherapy is essential for the management of nicotine dependence.

The purpose of this study is to analyze the business performance of human resource diversity of Korean manufacturing enterprises in China. And it has a great significance in the fact that it has been studied in accordance with the rapidly changing Chinese economic paradigm. In particular, the study was conducted on the 120 companies of manufacturing companies in China using the HCCP panel data of Korea Vocational Training Center in terms of human resource diversity and corporate performance. The results are summarized as follows. First, Corporate per capita education and training expenses and operating profit growth rate supported the Hypothesis 1-1, which has been favored by the Si-jin-ping government since the advancement of manufacturing enterprises in China has accelerated the entry and investment of foreign companies. Second, in the human resource development system, securing of human resources through education and training for core talent has a small effect on company performance. In this study, the enterprise human resource development system did not show any meaningful result. Third, the firms that implement the selective benefits system affected the rate of change of the operating profits, while the firms with the dedicated education organizations had negative influences, which supported the hypotheses 1-4 and rejected 1-2.

21세기 중국철강산업의 파급효과 변화추이 연구 -2002, 2007, 2012, 2017년 중국 투입산출표를 중심으로-

In this paper, we analyzed the trend of ripple effects of the Chinese steel industry for 20 years from the 21st century to the present. In particular, in 2002, 2007, and 2012, industrial classification standards were used as medium classification criteria (42 items), but the input output table in China in 2017 used the industry classification criteria as sub-classification criteria (149 items). It can be seen that there is a difference in the fact that detailed analysis was conducted. When looking at the related industries of the steel industry from 2002 to 2017, if there was a relationship mainly to traditional manufacturing industries such as communication equipment and other electronic equipment manufacturing, medical device manufacturing, electrical/mechanical and equipment manufacturing industries in the early 2000s. It can be seen that, after the steel industry gradually changed its policy from quantitative to qualitative, a relationship was gradually formed with the specialized manufacturing industries, which added technology to the traditional manufacturing industries such as specialized equipment manufacturing, other manufacturing, and measuring/instrument manufacturing. However, as a limitation of this study, the point of analysis that is always discussed is different from the present point. Because the publication of the input and output tables in China takes place on average 2-3 years later, it can be seen that there are difficulties in analyzing the current industrial relations. However, in order to supplement this, research provides important implications from a single point of view, if follow-up research is conducted continuously for a long time, the existing development trend can be seen. It is expected that more abundant research results that can infer the direction will be drawn.

Before and after the Chinese Economy Reform in 1978, Chinese Financial Market has been changed ``Mono Banking System`` to ``Multi-Layered Financial System`` which is for reforming and opening about financial sector after 1978. Although this reforming and opening is still insufficient, provides driving force for maintaining Chinese average economic growth 9.8% last 30 years. Financial industry decides nation`s competitive power because it supports to real economy as ``Fund broker`` and influences national economy including added value & job creation. Therefore, China has to develop their financial market for continuous economic growth and is requested to analyze of direct and indirect effects in diverse industries which is caused by this development. The purpose of this research are analyzing direct and indirect effects which will be happened to other Chinese industries by financial market development and understand the importance of these effects from the point of national economy view. Chinese input-output table in 2007 is used as a tool of this research and all kinds of ripple-effect and relation with other industries is analyzed using by ``Index of the Power of Dispersion`` & ``Index of the Sensitivity of Dispersion``.
