강원랜드 카지노 딜러의 셀프리더십을 통한 정서적 몰입 및 직무성과에 관한 연구
서세광 ( Seo Se Kwang ),지윤호 ( Ji Yunho ) 한국호텔리조트학회(구 한국호텔리조트카지노산학학회) 2021 호텔리조트연구 Vol.20 No.1
In a rapidly changing environment, casino companies are meeting various needs that customers’ wants and seeking ways to improve service quality and corporate competitiveness to provide differentiated services from other companies. This study is meaningful in that it has verified the impact of casino dealers' self leadership on their job performance. As the main results of the study, first, all three sub-factors of self- leadership (behavioral-oriented strategies, natural compensation strategies, and constructive thinking strategies) showed significant results in affective commitment. Second, affective commitment showed a statistically significant impact on job performance. Third, in the relationship between self- leadership and affective commitment, the culture of error management has been shown to have a partial control role. Based on the research results above, this study suggested implications for strategic human resource management for discriminatory and professional casino dealers. In addition, it presented ways to utilize self- leadership that can meet the goal of the company and explained the importance of forming a error management culture for innovative changes.

현재 컴퓨터 성능의 발달과 함께 GIS 서비스는 기존의 단순 지도 서비스를 비롯한 각 개체들의 위치 정보인 POI 서비스까지 요구되고 있다. 하지만 대부분의 GIS 서비스는 그 핵심적 기반이라 할 수 있는 지도 데이터를 표현하는데 있어서 각 개발 업체 및 연구기관마다 각기 다른 지도데이터 포맷을 사용하고 있다. 이는 곧 데이터의 중복 구축뿐만 아니라 기존 GIS간의 상호 운용성이 결여되어 서로 간에 호환 불가라는 문제점을 야기 시킨다. 또한, POI 서비스에서도 POI를 이루는 개체들에 대한 위치 정보가 불충분하여 단순히 지명 서비스만을 제공하고 있어, 다양한 정보 서비스를 제공 받고자 하는 사용자의 요구를 충족시키지 못하고 있다. 이에 본 논문에서는 지도 표준인 GML을 기반으로 하여 지도 가시화의 중복 구축 및 비호환성을 극복하고, 단순한 POI 정보에 대해서는 계층적이고 사용자 중심적인 위치정보를 구축하고 이를 가시화하는 GVP를 개발한다.

Ti표면의 전처리방법이 4-META/MMA-TBB 레진과의 접착강도에 미치는 영향
김교한,서세광 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.2
The present study investigated the effectiveness of several surface pretreatment methods on the bonding of Ti to adhesive resin. Commercially pure Ti and Ti-6Al-4V alloy were bonded by 4-META/MMA-TBB resin to stainless rods. Each specimen was polished with No. 1.000 sandpaper and then treated with various surface treatment methods, such as 50 ㎛ size of Al₂O₃particles sandblasting, tinplating, silicoating, combination of sandblasting and tinplating and combination of sandblasting and silicoating. The surface of pure Ti treated with sandblasting was roughened to irregular and retentive pattern and aluminum content on the treated surface was increased. The surface morphology treated with tinplating was similar to nontreated one and the surface composition showed almost no change. The surface morphology of silicoating groups was similar to the one of silicoated after sandblasting condition and in both group, carbon content was significantly increased. The surfaces morphology of tinplating was not changed at all. The surface observation results of commercially pure Ti and Ti-6Al-4V alloy specimens were similar, but Ti-6Ai-4V alloy specimens were similar, but Ti-6Al-4V alloy showed more amount of tin precipitations at tinplating groups. Average tensile bond strength of each group was ranged from 21.20 to 31.64 MPa. The tensile bond strength of each group did not show a difference at the 0.05 significance in one-way ANOVA test. Fracture mode of each specimens was almost resin cohesive fracture, and some adhesive fracture-like area was proved to be cohesive fracture in higher magnification. Thus, bonding strength of resin-Ti interface was stronger than that of 4-META/MMA-TBB resin itself.
