Purpose: This study investigated perception and plan of dental technologists regarding the old age and retirement for them to enjoy stable old age. Methods: Dental technologists working in Seoul, Incheon, and Gyeonggido were asked to fill out a self-administered questionnaire, and a total of 200 copies were used for analysis. The collected data were statistically analyzed by using SPSS 22.0(Statistical Package for Social Sciences. Chicago, IL, USA) (a=0.05). In order to compare perception toward old age preparation among the subjects, a Chi-square test was performed, and, to investigate the level of preparedness for old age according to general characteristics, t-test was performed. Results: In the analysis of the old age preparedness by age, there was a significant difference in financial preparation, Asset identification, use of retiring allowance, information gathering, senior town home, and stability (p<0.05). To the questions regarding perception toward retirement, the majority of the subjects (60.5%) answered they had thought about retirement, and many (23.9%) of them attributed the reason to job stress (23.9%). Regarding old age preparedness according to workplace, there was a significant difference in use of retirement allowance and education for old age preparedness between general dental laboratories and general hospitals (p<0.05). Conclusion: It is believed that, for preparation of dental technologists for stable old age, in addition to their personal effort, it is important to provide social support and practical measures to ensure welfare and retirement.

Operation and Maintenance (O&M) phase is the main contributor to the total lifecycle cost of a building. Previous studies have described that Building Information Models (BIM), if available with detailed asset information and their properties, can enable rapid troubleshooting and execution of O&M tasks by providing the required information of the facility. Despite the potential benefits, there is still rarely BIM with Mechanical, Electrical and Plumbing (MEP) assets and properties that are available for O&M. BIM is usually not in possession for existing buildings and generating BIM manually is a time-consuming process. Hence, there is a need for an automated approach that can reconstruct the MEP systems in BIM. Previous studies investigated automatic reconstruction of BIM using architectural drawings, structural drawings, or the combination with photos. But most of the previous studies are limited to reconstruct the architectural and structural components. Note that mechanical components in the building typically require more frequent maintenance than architectural or structural components. However, the building mechanical drawings are relatively more complex due to various type of symbols that are used to represent the mechanical systems. In order to address this challenge, this paper proposed a symbol recognition framework that can automatically recognize the different type of symbols in the building mechanical drawings. This study applied vector-based computer vision techniques to recognize the symbols and their properties (e.g., location, type, etc.) in two vector-based input documents: 2D drawings and the symbol description document. The framework not only enables recognizing and locating the mechanical component of interest for BIM reconstruction purpose but opens the possibility of merging the updated information into the current BIM in the future reducing the time of repeated manual creation of BIM after every renovation project.

Background: This study is designed to estimate the factors that affect the level of three different performance (publicity, efficiency, profitability) among regional public hospitals. Methods: The units of analysis are the regional 30 hospitals, which have the operating data during 22 years (from 1933 to 2014). The research method is used by fixed panel analysis. The publicity is measured by medicaid outpatient proportion and medicaid inpatient proportion. The efficiency is measured by two types of efficient score by DEA (data envelopment analysis). The profitability is measured by medical income to medical revenue and ROA (return on total asset). Results: At first, the increase of bed gives negative affect to the publicity but give positive effect to the efficiency and profitability. Because it means the increase of the region population, it gives more profitability compare to hospital with small number of beds. The more the operating period is the higher effect to the publicity and efficiency because of it's refutation. The debt ratio gives negative effect to publicity, but positive effect to profitability. It is the normal belief that there is inverse relationship between publicity and profitability. The turnover rate of bed gives the negative affect to the publicity, but positive affect to the efficiency and profitability. That give us the implication that type of the inpatient make different effect the hospital performance. The ratio of labor cost give negative effect to all kind of performance. That means that the higher labor cost don't mean the higher publicity and labor cost control is very important factors to hospital performance. So the region hospital have to focus the labor factors more to make higher performance. Conclusion: As the conclusion, the independent variables give similar effect to the efficiency and the profitability, but give inverse effect to the publicity. That means that if an region hospital want to make the more publicity, it loss the higher efficiency and profitability. Specially publicity is higher negative relation with the profitability.

Purpose - Competitive industry structure and recent economic depression challenge a survival of Korean small- and medium-sized food franchising companies (SMFCs), albeit the explosive growth of the Korean food service industry for last few decades. Against this backdrop, it examines how these SMFCs overcome liabilities of smallness and resource scarcity to strengthen competitive advantage in the market. To tackle this, in this article we focus on corporate entrepreneurship and human resources as a knowledge-based asset for these SMFCs. Furthermore, the ratio of employee turnover is high in SMFCs. We view that such brain-drain may result in poor performance of the Korean SMFCs. As such, we pay attention to the role of organizational commitment to an organization as a solution for enhancing individual-level employees' loyalty toward their organization. Research design, data, and methodology - Our research question is to what extent corporate entrepreneurship (i.e., innovative organizational culture, organizational autonomy, and administrative innovation) affects an individual-level attitude toward the organization and, in turn, employee creativity and satisfaction in the Korean SMFCs context. We collected data from employees in SMFCs for three months. A total of 126 valid questionnaires were collected, and analyzed the data using partial least squares path modeling. Results - The reliable and valid measurement model feed into testing the structural model. Our findings suggest that innovative organizational culture and organizational autonomy positively affect employee commitment. Particularly, organizational autonomy has a greater effect than innovative culture on employee commitment. However, the relationship between administrative innovation and employee commitment is not significant. We also find that employee commitment positively affects both employee creativity and satisfaction. Conclusions - Our contribution to the existing franchising business and management literature is twofold. First, the conceptual model includes three antecedents in the organizational entrepreneurship dimension to organizational commitment. Second, we conceptualize organizational commitment as employee commitment, and validate its impact on employee creativity and job satisfaction at an individual performance level. Overall, this article suggests that it is critically important for the Korean SMFCs to develop corporate entrepreneurship in order to facilitate employees' positive attitudes toward their organizations.

환경·사회·지배구조(ESG) 성과가 투자자의 의사결정에 미치는 영향이 커지고 있다. 과거 기업의 재무적 성과에 집중하던 투자자의 시선이 기업을 둘러싼 이해관계자의 이익이라는 비재무적 성과로 확장하고 있는 것이다. 이런 배경에서 본 연구는 기업의 비재무적 성과인 ESG 성과가 기업위험에 미치는 영향을 분석하기 위해 한국기업지배구조원이 평가하는 기업을 대상으로 패널회귀분석을 실시하였다. 분석 결과 ESG 성과는 세 가지 기업위험(체계적위험, 비체계적위험, 총위험) 모두에 대해 음(-)의 영향을 미치고 있어 이해관계자이론과 위험관리이론을 지지하는 결과를 나타냈다. 본 연구의 시사점은 첫째, ESG는 비체계적위험 뿐만 아니라 광범위하고 무차별적인 체계적위험도 감소시키고, 둘째, 투자자는 ESG 투자를 집행함으로써 투자포트폴리오의 위험을 감소시킬 수 있고, 셋째, 기업은 ESG 경영의 보험기능을 활용함으로써 부정적인 상황에서도 안정적인 재무성과를 영위할 수 있으며, 마지막으로, 정부는 합리적인 ESG 관련 규제를 통해 기업의 재무적 건전성을 제고하면서 금융시장의 안정성을 높일 수 있다는 것이다.

고성오광대는 1950년대 말부터 학술조사가 시작되어 1964년 국가무형문화재로 지정되었다. 지정 당시까지는 종이탈을 사용하였으나 1965년에는 이미 나무탈로 바뀌었으며 이후 탈의 변화 양상이 매우 크다. 1960년에는 9개의 탈을 사용하였는데 문둥이, 초란이, 말뚝이, 청보양반, 젓양반, 할미, 제밀주 탈을 기본으로 하였으며 여기에 소무는 제밀주와, 청보양반과 비비양반은 영감과 탈을 겸용하기도 하였다. 황봉사와 상주는 탈을 쓰지 않고 맨얼굴로 등장했다. 1965년부터 고성오광대 연희용 탈은 전체가 나무탈로 바뀌었다. 상주, 마당쇠, 상두꾼을 제외한 전 배역이 탈을 쓰고 있는데 비비, 홍백양반, 봉사 탈은 1964년까지는 등장한 적이 없는 탈이다. 초라니는 종가도령으로 바뀌었고 청보양반은 원양반으로 대체되었다. 1969년을 기점으로 연희용 탈은 종류가 현재와 같아지는 안정기에 들어선다. 비비양반과 소무를 제외한 모든 등장인물들이 개별탈을 사용하여 총18점의 탈을 사용한다. 양반들은 적제양반까지 확실하게 분화되어 총 7명의 양반이 등장한다. 이렇게 탈의 종류와 재질 및 표현법에 변화가 큰 것은 1세대 탈 제작자가 사망하면서 탈 제작의 전승이 끊어진 이유도 있겠으나 지정 이후 연희자들이 맞닥뜨려야 했던 연희환경의 극심한 변화에도 그 원인이 있다. 연희자들의 자족적인 놀이였기 때문에 세부 사항에서는 엄격한 규칙이 적용되지 않는 유동적인 놀이였으나 민속예술경연대회에 참가하면서 점차 공연을 위한 준비로 바뀌었다. 춤이나 의상, 소품들도 점차 화려해졌고 시각적인 효과와 짜임새 있는 연출을 시도하면서 연희 전반의 변화와 함께 탈의 변화를 가져왔고 이를 보존회 내부에서도 수용하게 되었다.

The Buddhist costumes, unlike the ordinary ones, have not been studied comprehensively due to their religious, non-popular and non-social features. In this regard, this paper aimed at reviewing the styles and symbolic Characters of the monks' dancing costumes for the traditional Buddhist ceremony of 'Spirit Vulture Peak'(The Intangible Cultural Asset No.50.) Here, the 'Spirit Vulture Peak Ceremony' is a kind of Buddhist ceremony commemorating the Buddha's preaches on the peak of Mt. Grdhrakuta by means of symbolized ritual and reformation procedures. The methodology of this study depended on the research of literatures, personal observation of the actual ceremony and the discussion with Priest Park Song-am. The dancing style of the Ceremony can be divided into four categories; the cymbal dancing., the drum dancing , the butterfly dancing and the column-beating dancing. And for the dancing costumes, the loose ritual mantle, the long-sleeve robe and the buddhist costume are used; the loose mantle and the long-sleeve robe are for the drum dancing. The style of the loose mantle is rectangular, sewn every odd knot between 5 and 25 ones. According to the record, its color was initially grey or red-yellow, but varied depending on the local rules. The four corners of the loose mantle have a rectangular-cloth embroidery of sky & king patterns, and the center is embroidered with the Sun'Moon designs or 'Om/Nan' letters in the Korean spells. The light of Sun/ Moon designs symbolizing the sky and the earth respectively are indigenous to a particular school in Korea. The long-sleeve robe has a traditional over-coat style. and is called otherwise of if some design is added. The total clothing or dancing costumes for the Ceremony include 'the Dae-ryung (meaning great peake)loose mantle', 'the White Paldad(meaning Chinese Character eight) long-sleeve robe and the peaked hat. The Dae-ryung mantle is a kind of ritual costumes with the shorter length than the ordinary mantles, and has a character 'Ryung' in Chinese spell attached with three to six colors. The White Paldae robe is shorter than the ordinary robes in the total length but longer in the length of sleeves. It is put on over the mantle from the left shoulder, and used often for the butterfly and column-beating dancings. It is hoped that this study will promote the study on the customs and rites of the Buddhism rather than on the thoughts, and contribute to the further studies.
