The purpose of this study is to examine whether non-self perspective(NSP) reduces the negative effects of life stress experienced by middle-aged adults. an online survey was conducted using a sample of 207 adult men and women in their 40s and 50s, and a hierarchical regression analysis and simple slope analysis were performed. As a result, it was found that NSP modulates the negative effects of life stress on perceived stress and subjective well-being. Specifically, NSP reduced the positive effect of life event stress on perceived stress and reduced the negative effect on subjective well-being. The results of this study suggest that eastern and Buddhist self-view, NSP, has a buffering effect on life stress experienced by middle-aged adults. This study suggests that NSP should be considered as an important factor for coping with stress in middle-aged adults in counseling and clinical settings, and is expected to promote subsequent empirical research on the Buddhist concept of non-self. Finally, limitations and future studies are suggested.

An approach using complex potentials is presented for analysis of composite plate with an elliptical hole or a rectilinear crack. Composite structure is susceptible to encounter impact damages, which lead to considerable decrease in its residual strength. Such impact damages could be modeled as an equivalent elliptical hole or notch-like crack. Even though finite element method is widely used to analyze stresses or fracture mechanics parameters around such damage, it is tedious to make successive FE-modeling for damage tolerance assessment under fatigue loadings. In this point of view, the solutions based on complex potentials are very simple and easy to use. The computed results are also compared and discussed with those from FEA.

Purpose - Recently, as the franchise market has grown rapidly and competition has intensified, the creation of competitive advantage by companies has become important as a corporate survival strategy. Based on previous studies, this study proposed a theoretical framework for the structural relationship between psychological ownership (organization and job), job performance, and customer orientation. Research design, data, and methodology - This research examines the structural relationship between psychological ownership, job performance, and customer orientation in terms of employees. More specifically, in this model, psychological ownership consists of two sub-dimensions of organization and function. Research models and hypotheses have been developed for this purpose. A total of 409 respondents responded via surveys. 2 out of 409 respondents have been removed and a total of 407 were used for this study. The data were analyzed using frequency analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling with SPSS 21.0 and Amos 21.0 statistical program. Result - The results of the study are as follows. First, psychological ownership (organization and job) has a statistically significant positive effect on job performance. Second, psychological ownership of the job has a statistically significant positive effect on customer orientation. On the other hand, psychological ownership did not have a significant effect on customer orientation. Conclusions - The implications of this study are following as: From the theoretical point of view, this study distinguishes the psychological ownership of employees of a franchise corporate into two dimensions, organization and job, rather than a single dimension. Based on this, we examined the effect of psychological proprieties on job performance and customer orientation. This study also provides several implications. In a fiercely competitive franchise market, it is very important to analyze your employees to gain a competitive advantage over other competitors. It is meaningful to study the employees who work in the franchise. In addition, psychological ownership is an important variable that enhances job performance and leads to customer orientation, so the company needs to pay attention. Therefore, it needs to develop an internal marketing strategy that promotes psychological ownership.

This study exploratoryly examines the effect of time poverty experienced by tourists on the quality of tourism due to the recent rapid change in the tourism service system. Due to various reasons, the process of consuming considerable time and energy of the mind along with anxiety, tension, and anxiety caused by the sense of time poverty experienced by tourists occurs. As a result, time poverty comes and the quality of tourism decreases. On the other hand, the factor of trust in the change of the tourism service system is also an important axis for satisfaction, but if a problem occurs in efficiency related to time, satisfaction with the tourism service may decrease. From this point of view, this study conducted a literature review focusing on the fact that time poverty due to changes in the tourism service system reduces the satisfaction of tourists and even affects the quality of tourism. Through this, various implications were provided for the government's policy to support workers' leave.

Although laparoscopic pancreaticoduodenectomy (LPD) is considered as minimally invasive surgery, an advanced level of laparoscopic skill is still required. LPD comprises various procedures including reconstruction. Therefore, establishment of a safe approach at each step is needed. Prevention of intraoperative bleeding is the most important factor in safe completion of LPD. The establishment of effective retraction methods is also important at each site to prevent vascular injury. I also recommend the "uncinate process first" approach during initial cases of LPD, in which the branches of the inferior pancreaticoduodenal artery are dissected first, at points where they enter the uncinate process. This approach is performed at the left side of the superior mesenteric artery (SMA) before isolating the pancreatic head from the right aspect of the SMA, which allows safe dissection without bleeding. Safe and reliable reconstruction is also important to prevent postoperative complications. Laparoscopic pancreatojejunostomy requires highly skilled suturing technique. Pancreatojejunostomy through a small abdominal incision, as in hybrid-LPD, facilitates reconstruction. In LPD, the surgical view is limited. Therefore, we must carefully verify the position of the pancreaticobiliary limb. A twisted mesentery may cause severe congestion of the pancreaticobiliary limb following reconstruction, resulting in severe complications. We must secure the appropriate position of the pancreaticobiliary limb before starting reconstruction. We describe the incidence of intraoperative and postoperative complications and appropriate technique for safe performance of LPD.

Maintaining sea superiority through successful mission accomplishments of warships is being proved to be an important factor of winning a war, as in the Ukraine-Russia war. in order to ensure the ability of a warship to perform its duties, the survivability of the warship must be strengthened. In particular, among the survivability factors, vulnerability is closely related to a damage assessment, and these vulnerability data are used as basic data to measure the mission capability. The warship's mission capability is usually measured using a wargame model, but only the operational effects of a macroscopic view are measured with a theater level resolution. In order to analyze the effectiveness and efficiency of a weapon system in the context of advanced weapon systems and equipments, a warship's mission capability must be measured at the engagement level resolution. To this end, not the relationship between the displacement tonnage and the weight of warheads applied in the theater level model, but an engagement level resolution vulnerability assessment method that can specify physical and functional damage at the hit position should be applied. This study proposes a method of measuring a warship's mission capability by applying the warship vulnerability assessment method to the naval engagement level analysis model. The result can be used as basic data in developing engagement algorithms for effective and efficient operation tactics to be implemented from a single unit weapon system to multiple warships.

Unlike previous studies on AI chatbot preference that focused mostly on satisfaction, this study considered both satisfaction and dissatisfaction. This study established that (1) AI chatbot preference is driven by attractive, must-be, and one-dimensional qualities, (2) AI chatbot need to develop service strategies by taking into account users' satisfaction and dissatisfaction in accordance with preference drivers, and (3) users view interaction as a requisite and thus, if they are not satisfied with services of a AI chatbot, they don't tend to appeal their opinion and leave the service with AI chatbot. This study emphasizes that a AI chatbot that desires to be a dominant market player must provide differentiated services according to the preference drivers and must continuously encourage user participation in order to improve service quality.
