Background and Purpose: The Korean-Mini Mental State Examination, 2nd edition (K-MMSE~2) was recently released. This study aimed to determine whether the K-MMSE~2: Standard Version (K-MMSE~2:SV) had the same test characteristics as the K-MMSE. Methods: A total of 1,514 healthy community-based participants aged 19 to 90 years were administered the K-MMSE~2:SV Blue Form along with the language items from the K-MMSE. The item and test characteristics and test information for the K-MMSE~2:SV and K-MMSE were compared using Item Response Theory analysis. Results: Item discriminations for the K-MMSE~2:SV and K-MMSE were above the moderate range for all items except Recall. Most of the items on the K-MMSE~2:SV and K-MMSE had item category difficulty in the very easy or easy range. The test information curve (TIC) showed that the K-MMSE~2:SV and K-MMSE provide almost the same amount of information (27.86 vs. 28.44), with both tests providing the most information at an ability level of -1.57. The generalizability (G) coefficient for the K-MMSE~2:SV and K-MMSE was 0.99. Conclusions: These results indicate that the K-MMSE~2:SV and K-MMSE are equally optimal tests for screening for mild cognitive impairment and early dementia. Given that the amount of test information provided by the two tests was almost identical, the shapes of the TICs were very similar, and the G coefficient was close to 1, we can conclude that the K-MMSE and K-MMSE~2:SV are equivalent tests.

New occupational qualification system built on NCS(National Competency Standard) aimed to induce industries, the final appliers of qualification, to play a leading role in designing qualification and to spontaneously apply such qualification standard to employment and promotion so as to reinforce universality of qualification. In this study, we verified the validity of NCS level of qualification categories for 130 occupational fields by redesigning NCS-based new occupational qualification system with a focus on 7 major areas, including mechanical field, which were found to have wide-ranging social ripple effect throughout society and high acceptability in 2014. The results of study on suitability at qualification level suggested the followings: First, there is a difference in number of competency units for each qualification category, depending on area. New qualification covering 7 major areas included 15.3 competency units for each qualification category, which exceeds the number of competency units(about 10 units) in subdivided NCS. By field, some difference was found with 7.9 competency units for cultural field and 22.6 competency units for information and communication area. Second, preference above normal level was observed in the criteria, procedure and method for determining qualification redesigning. However, preference below normal level was exhibited in connection with possibility of linkage with overseas qualifications, although preference was above normal level in relation to the suitability of design/qualification level and qualification categories based on lifelong career development path within scope of NCS as the criteria for determining the redesign of qualification categories. Second, we compared NCS level and SC(Sector Council level, and the results showed that NCS level was found to be somewhat well-defined. For the qualifications with different definitions, it was deemed difficult to determine superiority between NCS level and SC level. However, majority opinion indicated that it would be desirable to follow NCS level because NCS was created through collection of opinions for a prolonged period.

This study analyzed the content of special selling events in internet shopping malls to establish academic standards for special selling events as tools for sales promotions and to suggest systematic guidelines for marketers designing special selling events. Based on a content analysis, the titles of special selling events from four internet shopping malls selling women's apparel were analyzed. A total of 692 titles were analyzed. The results are as follow. First, the contents categories of special selling events could be classified into two groups such as 'theme' and 'tool'. Season, product characteristics, style, advice/information, brand, annual/social events, and marketing events were the main content categories that came under the 'theme' group; in addition, the price benefit, free offers, product mix, and marketing technique were the main content categories that came under the 'tool' group. Each main content category was subdivided into several segment content categories. Second, most of the titles were composed of more than two segment content categories that involved various information and benefits; however, the portion of titles composed of only theme related content categories or only tool related content categories was substantial. Furthermore, the theme related content categories were more than the tool related content categories. Third, the usage frequencies of the contents categories were analyzed. The upcoming season, single brand, sale/discount, item/material/color, special price/lowest price, and period/time/quantity limits were the segment content categories that held a high rank. Forth, most of the factors that evoked the unplanned purchases of consumers were related to the content categories of special sale events.

This study aims to analyze features of topics about AI(Artificial Intelligence) which is gaining a massive attention these days. Newspaper articles published from 2016 to June, 2017 were selected to analyze key subjects. The reason why the period was selected is people started to get attention on AI since 2016 as AlphaGo came out and gave a shock. The number of coded main message was 1,210 in 525 newspaper articles in total. The messages were categorized as three subject categories: the seven major categories, 62 middle categories. and minor categories. The seven major categories contains issues such as AI research, AI application, AI business, AI era, AI argument, AlphaGo, and other topics. The first features of issues about AI found in the major subject categories is that they are various and complicate. Second, it is important that social and policy-level issues related AI, such as job losses, misuse, and error should be dealt with to utilize AI safely. Last, issues related the role of human and revolution of education system in the AI era were shown as subjects which are important but hard to discuss.

Purpose: To develop the patient classification system based on the resource utilization for reimbursement of long-term care hospitals in Korea. Method: Health Insurance Review & Assessment Service (HIRA) conducted a survey in July 2006 that included 2,899 patients from 35 long-term care hospitals. To calculate resource utilization, we measured care time of direct care staff (physicians, nursing personnel, physical and occupational therapists, social workers). The survey of patient characteristics included ADL, cognitive and behavioral status, diseases and treatments. Major category criteria was developed by modified delphi method from 9 experts. Each category was divided into 2-3 groups by ADL using tree regression. Relative resource use was expressed as a case mix index (CMI) calculated as a proportion of mean resource use. Result: This patient classification system composed of 6 major categories (ultra high medical care, high medical care, medium medical care, behavioral problem, impaired cognition and reduced physical function) and 11 subgroups by ADL score. The differences of CMI between groups were statistically significant (p<.0001). Homogeneity of groups was examined by total coefficient of variation (CV) of CMI. The range of CV was 29.68-40.77%. Conclusions: This patient classification system is feasible for reimbursement of long-term care hospitals.

In this paper, we investigate the effects of group composition according to the personality type of learner on the content of discussion in web-based synchronous online discussion. The experiment for this study was conducted with high school students. First, we conducted the MBTI(Myers Briggs Type Indicator) test and based upon the result, we classified learners into 3 groups; introverts group, extroverts group, and introverts/extroverts mixed group. After the online discussion, the content of discussion were analyzed by the units of meaning, based on the four dimensions which were proposed in the 'content analysis model' by Henri(l992). Among four dimensions, 'social' and 'interactive' dimension belonged to category of inter-dependence, and 'cognitive' and 'metacognitive' dimension belonged to category of subject-relevance. The introverts/extroverts mixed group, which was heterogeneously composed, had the most positive effects on the total numbers of the units of meaning, the inter-dependence, and the subject-relevance of the contents of discussion.

Objectives The purpose of this study was to identify the research trends and major fields of Sasang Constitutional Medicine by analyzing the topics of papers contained in the Journal of Sasang Constitutional Medicine from the first issue to 2018. Methods To classify the research themes of the paper, theory, Characteristics in Sasang Constitution(SC), Diagnosis in SC, Treatment in SC, etc. categories and subcategories were created. Two researchers reviewed the title, abstract, and text of the paper and classified them according to the category classification. In case of disagreement, the category was determined through discussion with one of the remaining researchers. Results & Conclusions A total of 1,169 papers published in the Journal of Sasang Constitutional Medicine from the first issue to 2018. The number of published papers has increased steadily since the first issue of the Journal of Sasang Constitutional Medicine, and in 2008, the largest number of papers were published, but since then, the number of papers has gradually decreased. When classifying the categories of published papers according to research themes, the Theory field occupied a large portion in the early stages, but since then, the proportion has decreased steadily, and the number of publications has plummeted since 2012. On the other hand, in Treatment in SC field, its proportion has soared to account for about half of the papers since 2001. In Characteristics in SC and Diagnosis in SC fields, since the early 1990s, the number of publications has been consistently maintained.

Many museums have recently employed digital technologies in exhibition installations to provide visitors with interactive experiences with the installations, not just audiences. However, most of them have focused on the adoption of new prototypes or technologies, not considering user experiences of those systems carefully. This study developed an evaluation tool for usability of the tangible user interfaces and conducted a usability study on museum installations emphasizing user interaction and experience. The evaluation tool is composed of 5 features of tangible user interfaces such as tangible, interaction, convenience, representation, spatial interaction and social interaction, and 24 items. The museum we investigated is the Gwacheon National Science Museum, where 8 installations, classified 4 categories, were selected for the usability study. We recruited 6 undergraduate students, who were divided into 2 teams, each team having 3 students. Three students in a team manipulated and experience each installation together and reported their evaluation score through the questionnaire and interviews. The results showed that the score of the usability for the category 3, which requires students to move their bodies for the interaction, is the highest one because it features with spatial interaction. Students expressed much interest in the category 4, which utilizes users' other senses, however, the score of the usability is the lowest because the interaction is temporary and repetitive. Most installations are well designed in terms of control constraints, legibility, lower thresholds, participation encouragement, and open to the public, but pooly designed in terms of multiple access points, configurability, accurate movement, ambient media, and full-body interaction.
