This writing is for the purpose of investigating the specific character and problem point of China arbitration system which has near 90 years history and overviewing the drift of system improvement which happens recently. The arbitration system of China which traditionally does not acknowledge ad hoc arbitration, unlike most of the other nations that employ The UNCITRAL model law and make it their own legislation, is restrictive to the parties concerned principle of private autonomy considerably. Also the independence of arbitration is delicate, because of a civil characteristic weakness of the arbitral institutions and the intervention of the courts on the arbitration procedure and award. The dual system of domestic and international arbitration which maintains after enforcement of 1994 arbitration law is often to be a primary factor interrupting the development of Chinese arbitration system and making it vulnerable to challenges. The system improvement demand of the recent time reflects this point and makes the arbitration system of China to a international standard rather than now, so it is a desirable direction for China to be as the member of the world economy to be globalization.

Thin walled steel bridge-piers/columns are vulnerable to damage, when subjected to earthquake excitations. Local buckling, global buckling or interaction between local and global buckling usually is the cause of this damage, which results in significant strength reduction of the member. In this study new innovative design concepts, "thin-walled corrugated steel columns" and "thin-walled cellular steel columns" are presented, which allow the column to undergo large plastic deformations without significant strength reduction; hence dissipate energy under cyclic loading. It is shown that, compared with the conventional designs, circular and stiffened box sections, these new innovative concepts might results in cost-effective designs, with improved buckling and ductility properties. Using a finite element model, that takes the non-linear material properties into consideration, it is shown that the corrugations will act like longitudinal stiffeners that are supporting each other, thus improving the buckling behavior and allowing for reduction of the overall wall thickness of the column.

Singapore and Thailand have been rapidly ageing. There has been a growing demand for eldercarers in the home-setting for which migrant domestic workers have filled the role. This paper examines the Association of Southeast Asian Nations (ASEAN) Consensus governing women migrant workers entering the eldercare sector. It argues that because the ASEAN Consensus is not legally binding, it only serves to reinforce the sovereignty of states in the treatment of migrant workers instead of member states acting in unison to ensure labour protections for this group; as a result, Singapore and Thailand do not feel the need to step up protections for this group of workers according to national labor laws and hence low-skilled women migrant workers entering the eldercare sector continue to be vulnerable to labour abuses. Thus as with globalization, the ASEAN Economic Community manifests the paradox of borders: that while states are economically interconnected and interdependent, they are simultaneously disconnected and independent from each other.

Roll forming process is one of the most widely used processes in the world for forming metals such as a furniture drawer guide or an up and down slide guide. It can manufacture goods of the uniform cross section on a large scale throughout the continuous processing. In the domestic design and manufacture, roll forming process for production is taking most of the method of 2-point under rail slide. However, this method is vulnerable to the structural strength and stiffness is not suitable for high load conditions. Therefore, through systematic study of high load, low noise 3-point ball type of under rail slide its own design and manufacturing technology is the need to build. In this paper, to make center member of 3-point ball-type under rail slide for the refrigerator doors, the roll forming modeling and simulation are performed. Tensile test is performed about SCP-1 1/2H for determine the mechanical properties of materials. Modeling and simulation of roll forming is used MSC.MARC software of a dedicated analysis program used by rigid plastic finite element method. Interference between the roll and the final shape are predicted from the results of the simulation.

Flange and web local buckling in beam plastic hinge regions of steel moment frames can prevent beam-column connections from achieving adequate plastic rotations under earthquake-induced forces. Reducing the flange-web slenderness ratios (FSR/WSR) of beams is the most effective way in mitigating local member buckling as stipulated in the latest seismic design specifications. However, existing steel moment frame buildings with beams that lack the adequate slenderness ratios set forth for new buildings are vulnerable to local member buckling and thereby system-wise instability prior to reaching the required plastic rotation capacities specified for new buildings. This paper presents results from a research study investigating the cyclic behavior of steel I-beams modified by a welded haunch at the bottom flange and reinforced with glass fiber reinforced polymers at the plastic hinge region. Cantilever I-sections with a triangular haunch at the bottom flange and flange slenderness ratios higher then those stipulated in current design specifications were analyzed under reversed cyclic loading. Beam sections with different depth/width and flange/web slenderness ratios (FSR/WSR) were considered. The effect of GFRP thickness, width, and length on stabilizing plastic local buckling was investigated. The FEA results revealed that the contribution of GFRP strips to mitigation of local buckling increases with increasing depth/width ratio and decreasing FSR and WSR. Provided that the interfacial shear strength of the steel/GFRP bond surface is at least 15 MPa, GFRP reinforcement can enable deep beams with FSR of 8-9 and WSR below 55 to maintain plastic rotations in the order of 0.02 radians without experiencing any local buckling.

The main objective of the study is to measure the vulnerability of Indonesia's financial system stability in response to external shocks, including from regional economies namely three biggest Indonesia major trading partners (China, the U.S and Japan) and other external factors (oil price and the federal funds rate). Using Autoregressive Distributed Lag (ARDL) model and Orthogonalized Impulse Response Function (OIRF) with quarterly data over the period Q4 2002 - Q1 2016, results confirm that, 1) oil price response has the largest effect to Indonesia financial stability system and the effect period is the longest compared to others, represented by NPL and IHSG; 2) among those three economies, only China's economic growth has significantly positive effect to Indonesia financial stability system. Based on the findings it is better for the authorities to: 1) Diversify international trade commodities by decreasing share of oil, gas, and mining export and boosting other potential sectors such as manufacture, and fisheries; 2) Ensure the survival of Indonesia large coal exporter companies without neglecting burden of national budget; and 3) Create buffer for demand shock from specific countries by diversifying and increasing share of trading from other countries particularly from ASEAN member states.

Objectives: The number of cases of hepatitis A virus (HAV) infections has sharply increased in Korea, especially among young adults. In this study, an HAV outbreak in a facility for disabled people was investigated, and we found epidemiological differences both between 2 different generations and between generally abled and disabled groups. Methods: We analyzed the incubation period and attack rate of an HAV outbreak and investigated the prevalence of HAV antibodies among the staff and residents of a facility for the disabled. We performed a retrospective cohort study during the HAV outbreak, which lasted from February 8 to 25, 2019, including examinations of HAV antibody tests and post-exposure HAV vaccination for the staff or residents of the facility. Results: There were 9 confirmed cases in 2 staff members and 7 residents. Among 53 people (30 staff and 23 residents), except for the 9 confirmed cases and 1 staff member with a known history of HAV infection, HAV seroprevalence was seen in 16.7% of the staff under 40 years of age and 95.2% of those over 40 years of age, while the corresponding rates in the residents were 0.0% and 58.8%, respectively. Conclusions: This result implies that it is necessary to prioritize HAV vaccination for vulnerable groups and workers of residential care facilities.

Urban space structure in South Korea when through drastic changes ever since public housing policies began their full-fledge implementation. That is, public housing policies represent the main cause for formation of the current urban space structure, as the public houses are constructed in accordance with changes of demographic/social structure, considering changes of housing demand, in urban spaces demanded by the end users. After rapid industrialization and urbanization in the 1960's, each government in different periods have implemented housing supply policies through massive urban developments, to resolve the issue of housing shortage and residential instability. Phase 1 New Towns were developed in the 1980's resulting in suburbanization of the Seoul Area, followed by urban sprawl due to construction of small-size New Towns after deregulation in the 1990's, and construction of Phase 2 New Towns for resolution of housing shortage in the early 2000's and the resulting urban problems. In the mid-2000's, construction of Bogeumjari houses in GB areas led to insufficient housing supply in downtown areas, and the period after 2010 witnessed continuous deterioration of existing urban areas and acceleration of the rental housing crisis caused by rental housing shortage in downtown areas. Moreover, the residentially vulnerable classes consisting of young, 1~2-member households is expanding, with the real estate market in recess. Therefore, the government is trying to achieve urban regeneration through public housing policies so as to resolve the urban space problem and the housing problem at the same time, and the Happiness Housing Project has been implemented as a policy to achieve that goal. The Happiness Housing Project for young, residentially vulnerable classes in downtown areas, is going through diversification aimed at conjunction with urban regeneration projects in downtown areas, as exemplified by conversion of rental houses in residential environment improvement project districts and redevelopment/reconstruction project districts into happiness housing, and supply of happiness housing in conjunction with small reorganization projects for deteriorated residential areas in such areas as those excluded from New Town designation. Continuous supply of Happiness Housing in conjunction with urban regeneration requires mixed-use residential development which includes convenience facilities and public facilities, along with improvement of rental conditions (rental period/rent) and diversification of project methods, considering that the project is implemented in downtown areas.

Introduction: After 17 years since the first production of humidifier disinfectants in Korea, Korea Centers for Disease Control and Prevention (KCDC) announced that the odds ratio of lung injury related with humidifier disinfectant usage was 47.3 (95% confidence interval 6.0-369.7) according to a case-control study with 18 adult cases, including 8 pregnant women at a university hospital in Seoul. Results: From September 2011 to April 2012, one-hundred and seventy four victim cases have been reported to an environmental non-governmental group (NGO). We summarized timetable of humidifier disinfectants accidents, analyzed health outcomes (death, lung or lung and heart transplantation, pulmonary disease) of reported victims, and classified some information for humidifier disinfectants with health outcomes, and government action for this accident. Among the victims, number of death cases are 52 (30.0%), including 26 babies less than 3 years old. Sixty-nine victims come from twenty-seven family with 2 to 4 members per family. About twenty types of humidifier disinfectant products and about 600,000 product items a year have been sold. Fifty-two death cases used 7 different types of disinfectant products, including imported goods and some private brands of well-known supermarkets. KCDC confirmed inhalation toxicity of 6 products through an animal experimental test, and based on this observation recalled disinfectants containing PHMG (polyhexamethylene guanidine) and PGH (Oligo(2-(2-ethoxy)ethoxyethyl guanidinium chloride). Discussions: The use of these biocides involved highly fatal consequences among biologically vulnerable victims, such as pregnant women, several family member victims after semi-acute exposure. This is the first biocide disaster in Korea with non-specific targets, and unknown scale of victims, warranting concerns on use of biocides in the living environment. Conclusions: Special administrative agency for chemical safety and compensation act for environmental health victims are needed to prevent similar problems.

인터넷은행 환경 조성과 관련하여 금융당국이 발표한 비대면 실명확인 정책은 대면 이상의 정확성을 기하기 위해 다중확인을 원칙으로 하고 있다. 인터넷은행은 기존 인터넷뱅킹과 법적 실체와 사업모델이 다른데, 본인확인 구조로써 인터넷뱅킹의 본인확인 구조를 유지한 채 실명확인만 대면에서 비대면으로 대체하는 것은 최초 가입자에게 불편을 줄 뿐 아니라, 엄격한 대면확인을 거치는 인터넷뱅킹보다 보안위험에 더 노출될 수 있다. 본 연구는 인터넷은행의 서비스 단계를 등급화하고, 등급에 따라 차등화된 서비스등록 및 이용이 이루어지도록 개선된 본인확인 구조를 제안한다. 또한, 인터넷은행에 대해 발생할 수 있는 보안취약점과 공격모델을 수립하고, 각 공격모델에 대한 인증매체의 보안특성과 서비스 단계별 안전성을 분석한 결과 등급에 따라 기존 인터넷뱅킹보다 비슷하거나 더 높은 안전성을 제공하고, 이용자 가입 유도 측면에서 유용함을 확인하였다.
