Asbestos is the name of a group of minerals with long and thin fibers that originate naturally in the environment. Asbestos mainly affects lungs and the membrane that surrounds the lungs. In general, PCM (phase contrast microscopy) and PLM (polarized light microscopy) have been used to analyze asbestos fibers. However, these methods have often problems to over-estimate number concentration when counting real asbestos fibers. Moreover, there are many difficulties when separating and identifying various asbestos and non-asbestos fibers. In order to determine quantitative information on fibrous particles, source profiles for asbestos and non-asbestos fibers must be initially developed on the basis of their chemical compositions and physical parameters. In our study, a SEM/EDX was used to develop source profiles from known asbestos samples as reference samples. We could make the source profile matrix consisting of 6 types of asbestos fibers and 2 types of non-asbestos fibers by analyzing 380 fibers. Based on these profiles, a rule building expert system was developed by using the visual basic application (VBA). Various fibers were successfully classified by 2 simple rules in the EXCEL environment based on several visual steps such as inserting data, viewing results, and saving results. For a case study to test the expert system, samples from a construction materials and from various indoor environments such as a residental area, a preschool classroom, and an underground store were collected and analyzed. As a result of the survey, a total of 76 individual test fiber particles was well classified into 5 different types of particle classes; 9.3% of chrysotile, 15.4% of amosite, 0.8 of crocidolite, 4.2% of tremolite, 5.8% glass fiber, 21.1% of other fibers, and 43.5% of unknown fibers in terms of number concentration. Even though unknown portion was high, it will be decreased markedly when expanding fiber source profiles.

The purpose of this study was to draw policy implications for the development and expansion of Korea's forest ODA through investigating the perceptions of stakeholder on the fields that contributed the development of forestry in Korea and would have competitiveness in developing countries and priority fields for Korea's forest ODA. For this, the survey was conducted for 248 subjects from the general and expert stakeholder groups. Chi-square test in cross analysis, independent sample t-test, ANOVA and Duncan test were conducted to compare the difference of perceptions by group. The whole general and expert groups consider that 'forest conservation and rehabilitation' contributed to the development of Korea's forestry most and consider its global competitiveness most high. Comparing expert groups, ODA experts evaluated the competitiveness of 'capacity building for policies, institutions and research' higher than the forestry experts. For priority fields of Korea's forest ODA, general groups perceived 'management of CERs' and 'conservation of biodiversity' most important, showing the clear difference in perception compared to that of experts. In Conclusion, for the effective forest ODA of Korea, the effort to fill the gap between the general and expert groups needs to be made, as well as developing forestry capacity building programs to cope with the fields such as climate change adaptation and biodiversity conservation, which is newly required in a global society, in addition to using the past experience of forest rehabilitation in Korea. It will be useful for the rehabilitation of North Korea's forest in the future.

The purpose of this research is to analyze authority and expertise of internally-selected Director of Presidential Security Service (PSS) through case-studies of the 9th Director of PSS Sang-Bum Park and the 13th Director of PSS Sang-Kuk Yeom, and to provide suggestions as to how to improve the expertise of PSS director and how to make PSS more trusted by the president and citizens. To do so, this study employs qualitative research on various references while acquiring testimonies from an expert group. The result of the research is as follows. First, the 9th Director of PSS Sang-Bum Park and the 13th Director of PSS Sang-Kuk Yeom are categorized as non-authoritative Director of Presidential Security Service. Second the 9th Director of PSS Sang-Bum Park and the 13th Director of PSS Sang-Kuk Yeom are categorized as expert-type Director of Presidential Security Service. It must be acknowledged that the authority of PSS directors does not come from close relationship with president or physical distance, but from legality and professionalism. Therefore, when appointing a person who is in charge of his/her own safety, the president must consider national security and professionalism in order to succeed as a ready president.

The smart factory is an important axis of the 4th industrial revolution. Smart factory is a system that induces the maximum efficiency and effectiveness of production using the IoT and intelligent sensing systems. The product lifecycle management technique is a method that can actively reflect the consumer's requirements in the smart factory and manage the entire process from the consumer to the post management. There have been many studies on product lifecycle management, but studies on how to organize product lifecycle management knowledge domains in preparation for the era of the 4th industrial revolution were insufficient. This study analyzed the opinions of a group of experts preparing for the 4th industrial revolution in terms of product lifecycle management. The impact of the 4th industrial revolution on the detailed knowledge areas of product lifecycle management was investigated. The changes in product lifecycle management were summarized using a qualitative data analysis technique for a group of experts. Based on the opinions of experts, the product lifecycle management, which consists of a total of 30 detailed knowledge areas, was prepared to supplement or prepare for the 4th industrial revolution. This study investigates changes in product lifecycle management in preparation for the 4th industrial revolution in the knowledge domain of the existing defined product life cycle management. In future research, it is necessary to redefine the knowledge domain of product life cycle management suitable for the era of the 4th industrial revolution and investigate the perception of experts. Considering the social culture and technological change factors of the 4th industrial revolution, the scope and scope of product life cycle management can be newly defined.

Purpose: This study is to verify the validity and reliability of classified items and criteria of the patient classification system(PCS) based on Park's definition of nursing intensity. Methods: An expert group of 8 persons verified the content validity of the tools. The 1817 inpatients at a tertiary hospital in Seoul, Korea were classified into 4 groups according to two tools for verifying concurrent validity and interraters' reliability. These verifications were performed from September to October, 2004. Results: Nursing domains of the tools have been divided into 12 items: hygiene, nutrition, elimination, exercise & activity, education & counseling, emotional support, communication & consciousness, treatment & examination, medication, measurement & observation, coordination of multidisciplinary team, admission & discharge & transfer management. Content validity was verified by the content validity index(above 0.75 in all 12 areas). Interraters' reliability was no significant difference in the results of the patient classification between the two raters(A group 93.75%. B group 88.24%). Concurrent validity was also verified by the agreement of two tools(73.7%). Conclusion: These results showed that the reliability and validity of the PCS based on the nursing intensity were verified. These will use an data for nursing productivity in the future.

Purpose: The study was done to develop an evidence-based enteral nutrition (EN) protocol for effective nutritional support for dysphagia in patients with acute stroke, and to evaluate effects of this protocol on clinical outcomes. Methods: A methodological study was used to develop the EN protocol and a quasi-experimental study to verify the effectiveness of the protocol. The preliminary EN protocol was drawn by selecting recommendations from previous well-designed EN guidelines, and then developing additional recommendations based on high-quality evidence. Content validation was assessed by an expert group, and clinical applicability by care providers and patients. The scale-level content validity index of the final EN protocol was 0.99. Assessment was done of differences in percentage of caloric goals achieved and presence of undernutrition, aspiration pneumonia, and gastrointestinal (GI) complications after application of the EN protocol. Results: In the EN protocol group, the percentage of caloric goals achieved ($R^2=.24$, p=.001) and the reduction of GI complications (p=.045) were significantly improved, but the presence of undernutrition (p=.296) and aspiration pneumonia (p=.601) did not differ from the usual care group. Conclusion: Results indicate that the new EN protocol for dysphagia in patients with acute stroke significantly increased their nutritional intake and reduced GI complications.

In 2006, the UNCITRAL Working Group II started a new project on the revision of the UNCITRAL Arbitration Rules of 1976. Ever since that time, 9 sessions of the Working Group II were devoted to the discussions on such topic. The Arbitration Rules has been acknowledged to be used for settling international disputes involving various disputing parties. In recent years, many treaty-based arbitrations have been subject to the Arbitration Rules. This article focuses on the discussions made in the 52nd session of the Working Group II where the third reading of the revised draft of the Arbitration Rules was completed except for a few provisions. Among the draft rules, the delegations were hardly able to reach an agreement with regard to Articles 2(2), 34(2), 41(3), (4), and (6). It is expected that those provisions would be agreed in the coming 43rd plenary session of the UNCITRAL. The use of the Arbitration Rules is dependent on the agreement by the disputing parties. It is not like the UNCITRAL Model Law on International Commercial Arbitration which was adopted in Korean legal system in 1999. However, the proper functioning of arbitration rules is essential for the efficient and successful operation of the arbitration system in a particular country. That is the reason why we should keep close attention on the discussions of the UNCITRAL with regard to the revision of the Arbitration Rules.
