In response to the increasing emphasis being placed on the importance of international cooperation as part of global efforts to cope with growing non proliferation, and security, concerns in the nuclear field, the Director General of the International Atomic Energy Agency (IAEA), Mohamed ElBaradei, appointed an international group of experts to consider possible multilateral approaches to the nuclear fuel cycle. The mandate of the Expert Group was three fold: ${\bullet}$ To identify and provide an analysis of issues and options relevant to multilateral approaches to the front and back ends of the nuclear fuel cycle; ${\bullet}$ To provide an overview of the policy, legal, security, economic, institutional and technological incentives and disincentives for cooperation in multilateral arrangements for the front and back ends of the nuclear fuel cycle; and ${\bullet}$ To provide a brief review of the historical and current experiences and analyses relating to multilateral fuel cycle arrangements relevant to the work of the Expert Group. The overall purpose was to assess MNAs in the framework of a double objective: strengthening the international nuclear non proliferation regime and making the peaceful uses of nuclear energy more economical and attractive. The Group identifies options for MNAs - options in terms of policy, institutional and legal factors - for those parts of the nuclear fuel cycle of greatest sensitivity from the point of view of proliferation risk. It also reflects the Groups deliberations on the corresponding benefits and disadvantages (pros and cons) of the various options and approaches. Although the Expert Group was able to agree to forward the resulting report to the Director General, it is important to note that the report does not reflect agreement by all of the experts on any of the options, nor a consensus assessment of their respective value. It is intended only to present options for MNAs, and to reflect on the range of considerations which could impact on the desirability and feasibility of those options.

East Asia's Regional Comprehensive Economic Partnership (RCEP) came into force in 2022 as the world's largest free trade agreement. RCEP was concluded, signed and brought into force in the face of major international uncertainty and is a significant boost to the global trading system. RCEP brings Australia, China, Japan, South Korea and New Zealand into the same agreement with the ten member ASEAN group at its centre. It keeps markets open and updates trade and investment rules in East Asia, a major centre of global economic activity, at a time of rising protectionism when the WTO itself is under threat. The agreement builds on ASEAN's free trade agreements and strengthens ASEAN centrality. One of the pillars of RCEP is an economic cooperation agenda which has its antecedents in ASEAN's approach to bringing along its least developed members and builds on the experience of capacity building in APEC and technical cooperation under the ASEAN Australia-New Zealand Free Trade Agreement. There is an opportunity to create a framework that facilitates deeper economic cooperation that involves experience-sharing, extending RCEP's rules and membership at the same time as strengthening political cooperation. The paper suggests some areas that might be best suited to cooperation - that is confidence and trust building instead of or before negotiation - and discusses how non-members may be engaged and the membership expanded. Options such as multilateralising provisions and becoming a platform for policy convergence and coordinating unilateral reforms are canvassed.

Background: Ulcerative colitis (UC) is the large intestine disease that results in chronic inflammation and ulcers in the colon. Rg3-enriched Korean Red Ginseng extract (Rg3-RGE) is known for its pharmacological activities. Persicaria tinctoria (PT) is also used in the treatment of various inflammatory diseases. The aim of this study is to investigate the attenuating effects of Rg3-RGE with PT on oxazolone (OXA)-induced UC in mice. Methods: A total of six groups of mice including control group, OXA (as model group, 1.5%) group, sulfasalazine (75 mg/kg) group, Rg3-RGE (20 mg/kg) group, PT (300 mg/kg) group, and Rg3-RGE (10 mg/kg) with PT (150 mg/kg) group. Data on the colon length, body weight, disease activity index (DAI), histological changes, nitric oxide (NO) assay, Real-time PCR of inflammatory factors, ELISA of inflammatory factors, Western blot, and flow cytometry analysis were obtained. Results: Overall, the combination treatment of Rg3-RGE and PT significantly improved the colon length and body weight and decreased the DAI in mice compared with the treatment with OXA. Additionally, the histological injury was also reduced by the combination treatment. Moreover, the NO production level and inflammatory mediators and cytokines were significantly downregulated in the Rg3-RGE with the PT group compared with the model group. Also, NLR family pyrin domain containing 3 (NLRP3) inflammasome and nuclear factor kappa B (NF-𝛋B) were suppressed in the combination treatment group compared with the OXA group. Furthermore, the number of immune cell subtypes of CD4⁺ T-helper cells, CD19⁺ B-cells, and CD4⁺ and CD25⁺ regulatory T-cells (Tregs) was improved in the Rg3-RGE with the PT group compared with the OXA group. Conclusion: Overall, the mixture of Rg3-RGE and PT is an effective therapeutic treatment for UC.

The purpose of the study was to develop a death education program and evaluate the effectiveness of the program on the attitudes toward death, suicidal ideation and meaning in life among university students. The participants were 24 students, 11 in the experimental group and 13 in the control group. The death education program was developed and practiced with the experimental group for 8 sessions. The death education program reduced the negative attitude significantly toward death, and increased the meaning in life significantly in the experimental group. Suicidal ideation was also decreased but it was not statistically significant. There were significant differences in attitude toward death and meaning in life between the experimental and control group but not in suicidal ideation.

For achieving team performance, organizations should consider member's competency and their collective competency simultaneously. The principal aim of this research is to examine relationships among collective competency, group cohesiveness, team performance. 438 employees composing 52 teams participated in this empirical study. Results show that the mean of member competency was not associated with team performance. Results also show that there was no effect of group cohesiveness on team performance. However, consistent expectation, the interactive effect of collective competency and group cohesiveness on team performance was significant. Implications for future research are also discussed.

This study was conducted to identify the linkage and cooperation experiences in public case-management services of visiting health care practitioners. Focus group interviews were conducted with three people in charge of providing visiting healthcare services in public health centers. A semi-structured interview questionnaire was developed in advance through discussions among researchers In response to the interview questions, study participants described in detail the success and failure factors associated with linkage and cooperation that they experienced while providing visiting healthcare services. The interview data were analyzed qualitatively to identify the main themes and sub-themes reflecting visiting nurses' experiences with linkage and cooperation. The three main themes were: 'Guidelines act as positive performance factors for community-based linkage and cooperation', 'Unstable employment and lack of an integrated system act as barriers to linkage and cooperation', and 'Necessary for multidimensional approach to promoting linkage and cooperation'. Based on these results, the authors propose the development of clear linkage and cooperation standards and procedures, thereby ensuring job security for visiting nurses. Moreover, an integrated information system should be developed and implemented.

This study was carried out to investigate the protective effect of crude saponin from Platycodon grandiflorum on Clinical chemical parameters in male rats acutely exposed to 2,3,7,8-tetrachlorodibenzo-ρ-dioxin (TCDD). Crude saponin was prepared from Korean Platycodon grandiflorum with Diaion HP-20 adsorption chromatography after extraction of 80% ethanol at 75℃. The crude saponin was confirmed by thin layer chrmatography. When compared with ginseng saponins, the crude saponin had both a few number of saponins and a broad distribution. Forty male rats (200±20 g) were divided into 4 groups. Normal control (NC) group received vehicle and saline; TCDD-treated (TT) group received TCDD (40 ㎍/kg, single dose) intraperitoneally; Platycodon grandiflorum saponin (PG5 and PG10) groups received crude saponin 5 mg/kg and 10 mg/kg (p.o), respectively, for 2 weeks before 1 week of TCDD-exposure. Increase of body weight was retarded greatly by TCDD-exposure. Body weight of animals in TT group was significantly decrease after 2 days of TCDD-exposure. However, body weights of animals in PG groups increased through the experimental perimental period, although the increasing rate was slower than that of NC group. Increases in contents of blood glucose, total cholesterol and triglyceride (TG) and activities of amylase, lipase, AST, ALT and LDH by toxic action of TCDD were significantly attenuated by crude saponin from Platycodon grandiflorum (P<0.05). In conclusion, these results suggest that crude saponin prepared from Korean Platycodon grandiflorum might be a member of useful protective agents against TCDD, which is one of the environmental hormones.

This study examined the effect of rope play through forest experience on children's self-confidence. Empirical analysis through the experimental design was carried out on an experimental group of 15 (seven male and eight female children) and a control group of 15 (nine male and six female children). Analysis of covariance (ANCOVA) for the effect between the experimental and control groups after the experimental treatment showed that the mean of the experimental group was significantly higher than that of the control group (F=357.350, p<.001). Rope play through forest experience has a statistically significant effect on the children's self-confidence. Consequently, rope play through forest experience between peers is a beneficial experience that helps improve children's self-confidence. Furthermore, it is a positive play activity to help them with a passive character boost to their self-confidence through cooperation between peers.
