Purpose: Evaluating hotel performance is crucial in the tourism industry, and expanding knowledge through value-centric innovation in distribution is approached from the service-dominant logic perspective. This study aims to explore and enhance understanding of efforts to improve hotel performance by introducing a new concept of significant value-centric innovation in distribution. A novel proposition is presented, synthesizing diverse marketing innovations through the lens of service-dominant logic to foster originality. Research Design, Data, and Methodology: Data from 166 respondents across various levels of hotel structural positions in Indonesia were analyzed using SEM-PLS. The relationship between market orientation and hotel performance was explored using the SEM-PLS technique. Results: The findings indicate that market orientation contributes to enhancing hotel performance. Additionally, value-centric innovation in distribution is crucial in addressing inconsistencies observed in previous studies and indicators related to variables significantly affecting hotel performance. Moreover, value-centric innovation in distribution directly improves performance indicators. Conclusions: The practical implication of this research is leveraging market orientation to enhance hotel performance. Hotel owners are encouraged to effectively implement value-centric innovation in distribution by fostering collaboratively generated shared value creation.

본 논문에서는 입력된 자연영상으로부터 도로 영역을 검출하기 위한 소실점 자동 예측 방법을 제안한다. 제안하는 방법에서는 도로 환경에서 안정적으로 소실점을 검출하기 위해 영상의 주방향성을 분석하여 영상 특징성분들이 집중되는 곳을 소실점으로 예측한다. 이를 위해 첫번째 단계에서는, 영상을 일정크기의 서브블록으로 분할하고 분할된 서브블록 내에서 임의의 에지 샘플을 선택하고 RANSAC을 적용하여 직선 모델을 예측함으로서 각 서브블록의 주방향성을 분석한다. 모든 블록에 대하여 주방향성을 검출한 후, 두 번째 단계에서 임의의 직선 샘플을 선택하고 RANSAC을 적용하여 교점 모델을 예측함으로서 각 직선들로 인한 교점 모델의 비용값을 측정하고 가장 높은 비용값의 교점 모델에 의한 평균점으로 소실점을 예측한다. 마지막으로 성능 검증을 위해 다양한 상황에 따른 정량적, 정성적 분석을 통해 제안하는 소실점 검출 알고리즘의 타당성과 효율성을 입증한다.

Objectives : This study was conducted to verify the influence organizational health has on customer orientation by hospital ownership. Methods : This survey was conducted on a public hospital, private hospital, and religious hospital, respectively, during March 2014 and a total of 210 questionnaires were used in the analysis. ANOVA and regression analysis were used to analyze the collected data. Results : The management environment factor of organizational health was statistically significant in the public hospital compared to the private hospital. The reliability factor of customer organization was statistically significant in the public hospital and religious hospital respectively compared to the private hospital. For reactivity, the religious hospital was statistically significant compared to private hospital. A positive influence was shown in the vitality factor at the public hospital, and community orientation at the private hospital, while both community orientation and career showed effects at the religious hospital. ICU had a negative influence on customer orientation at the private hospital. Conclusions : The reason vitality had a relatively more important effect on customer orientation in the public hospital was due that age group of 20~29 was the dominant socio-demographic factor. Furthermore, the influence of community orientation on customer orientation in the private hospital and religious hospital may be related to the nurses' career.

This paper proposes a new approach to palmprint verification based on the gradient, in which a palm image is considered to be a three-dimensional terrain. Principal lines and wrinkles make deep and shallow valleys on a palm landscape. Then the steepest slope direction in each local area is first computed using the Kirsch operator, after which an orientation map is created that represents the dominant slope direction of each pixel. In this study, three orientation maps were made with different scales to represent local and global gradient information. Next, feature matching based on pixel-unit comparison was performed. The experimental results showed that the proposed method is superior to several state-of-the-art methods. In addition, the verification could be greatly improved by fusing orientation maps with different scales.

2-D wavelet analysis is applied to bathymetric data from the KR1 area of Korea Deepsea Mining Area. The wavelet analysis is one of the quantitative methods to analyze the topography. The wavelet allows us to create filters to select for topography in a continuous variety of shapes, sizes, and orientation. The 2-D Linear B-spline filter, 100 BS and 100 NF, is convolved with bathymetric data to identify the location of abyssal hills and abyssal troughs in bathymetry. In addition, the 2-D derivative of Cubic B-spline filter, 60 BS and 60 NF, is applied to bathymetric data to find the slope of abyssal hill in bathymetry. These filters were rotated $5^{\circ}$ counterclockwise from NS to match the dominant orientation of seafloor lineament. Both filters result in good match with abyssal hills, troughs, and slopes. This method can apply to fault, fold, and other lineament structures description with variable size. The result of application shows that wavelet analysis of bathymetric data could be used with fundamental data of geophysical analysis.

The focal mechanisms of the earthquakes occurred in 2001 and 2002 are analyzed to understand the regional stress and tectonics in and around Korean Peninsula. The forty -three fault plane solutions are derived using the polarities of first arrival P-waves recorded at KIGAM, Bmh and KEPRI stations. The result suggest that thrust motion with significant amount of strike slip component is dominant mode of faulting. The larger population of mechanism is characterized by WNW-ESE striking nodal planes. NE-SW direction is interpreted as dominant compressional axis orientation of stress field. These solutions are similar to those of medium size earthquakes studied previously, which is known as typical regional tectonic stress orientation in and around Korean Peninsula.

In this paper the influence of fiber orientation of basalt and carbon inter-ply fabrics on the flexural properties of hybrid composite laminates was experimentally investigated. Four types of basalt/carbon/epoxy inter-ply hybrid composite laminates with varying angle ply orientation of reinforced basalt fiber and fixed orientation of carbon fiber were fabricated using hand lay-up technique. Three point bending test was performed according to ASTM 7264. The fracture surface analysis was carried out by scanning electron microscope (SEM). The results obtained from the four laminates were compared. Lay-up pattern of $[0B/+30B/-30B/0C]_S$ exhibits the best properties in terms of flexural strength and flexural modulus. Scanning electron microscopy results on the fracture surface showed that the interfacial de-bonding between the fibers and epoxy resin is a dominant fracture mode for all fiber lay-up schemes.

본 연구는 뇌졸중 환자와 정상 성인이 앉은 자세에서 동적으로 변화하는 지지면의 각도에 적응하여 신체를 정위시키는 능력에 차이가 있는지 알아보기 위해 실시되었다. 뇌졸중 환자 12명(남 6명, 여 6명)과 정상 성인 12명(남 6명, 여 6명)을 대상으로 실시하였고, 앉은 자세에서 지지면을 2가지 방향(우세측, 비우세측)으로 기울였을 때 수직선과 머리와 체간이 이루는 각도를 영상 동작 분석 시스템을 이용하여 측정하였다. 앉은 자세에서 우세한 쪽을 올렸을 때 뇌졸중 환자와 정상 성인의 사이의 머리와 체간의 각도는 유의한 차이를 보였다(p<0.05). 앉은 자세에서 비우세한 쪽을 올렸을 때 뇌졸중 환자와 정상 성인 사이의 머리와 체간의 각도는 유의한 차이를 보였다(p<0.05). 앉은 자세에서 비우세한 쪽을 내렸을 때 뇌졸중 환자와 정상 성인 사이의 머리와 체간의 각도는 유의한 차이를 보였다(p<0.05). 앉은 자세에서 우세한 쪽을 내렸을 때 뇌졸중 환자와 정상 성인 사이의 머리의 각도는 유의한 차이를 보였으나(p<0.05) 체간의 각도는 유의한 차이를 보이지 않았다(p>0.05). 본 연구의 결과, 뇌졸중 환자들이 정상 성인에 비해 동적으로 변화하는 지지면의 각도에 적응하여 신체를 정위시키는 능력에 있어서 다양한 결손이 있음을 확인하였다. 뇌졸중 환자가 앉은 자세에서 환경의 변화에 적응하여 신체를 정위시키는 능력의 분석을 통해 뇌졸중 환자의 앉은 자세 조절의 문제점을 좀 더 명확히 이해할 수 있을 것으로 여겨진다.

The structure and mechanical properties of TiN and TiCN thin films deposited on STD61 steel substrates by the RF-sputtering methods has been studied by using XPS, XRD, micro-hardness tester, scratch tester, and wear-resistance tester. XPS results showed that the TiCN thin film formed with chemical bonding state. The TiN thin films grew with (111) orientation having the lowest strain energy by compressive stress, whereas the TiCN thin films grew with both (111) and (200) orientation, but (200) orientation having the lowest surface energy becomes dominant as carbon contents increase. The pre-etching treatment of substrate did not affect on the preferred orientation of thin films, but it played an important role in improving mechanical properties of thin films such as the hardness, adhesion and wear- resistance. Especially, the TiCN thin films showed the superior wear resistances due to high hardness and low friction coefficient compared with TiN thin films.
