Every service firm must find ways to attract new customers, retain existing customers, and remain competitive and profitable. As competition increases, delivering better service becomes more important. Service quality is considered as a vital aspect for the success of the firms. Restaurant cannot be separated from the service quality they have to deliver. The development of restaurant is supported with the reputation of the country where the food comes from. Recently, one of the most trending topic is Korean wave which affects the Korean cuisine. A fuzzy AHP was employed to evaluate the service quality. It is more preferable than traditional AHP which is criticized for its inability to handle the uncertainty of the decision maker's perception. Six attributes are used to evaluate five Korean restaurants in Semarang, Indonesia. The result shows that innovation is the most important attribute. It seems that decision makers viewed the food variation and new method service as main factors that the restaurants have to manage. This finding can provide the managers with valuable insights into the attribute that reflects customers' perceptions; also to position their service based on their competitors. Validating the scale in other culture-based restaurants is an interesting area to be pursued.

A majority of the peoples in Indian cities depend on high fat diet, smoking, ghutka chewing and improper sleep, these all are lifestyle changes, can cause ischemic heart disease. Globally, ischemic heart disease (IHD) is the leading killer. Unani System of medicine not only provides well-based medical cures for diseases, but its holistic approaches as it possess unique principles of diet, lifestyle and particularly therapeutics, to balance and enrich all aspects of physiology and psyche. All diseases are the result of poor management of the six governing (or essential) factors, beyond the ability of physics or Tabiat to maintain and restore homeostasis. In this context, lifestyle diseases can be prevented by conscious changes to the person's diet, behavior and environment. The holistic approach of Unani medicine is well placed to cover the two main pillars of lifestyle diseases, namely, prevention and treatment. In this paper, we report on the prevalence of CAD in patients with known diagnosis of CAD and try to find out its relationship with different lifestyle changes.

Morchella is a genus of fungi with the ability to concentrate Cd both in the fruit-body and mycelium. However, the molecular mechanisms conferring resistance to Cd stress in Morchella are unknown. Here, RNA-based transcriptomic sequencing was used to identify the genes and pathways involved in Cd tolerance in Morchella spongiola. 7444 differentially expressed genes (DEGs) were identified by cultivating M. spongiola in media containing 0.15, 0.90, or 1.50 mg/L Cd²⁺. The DEGs were divided into six sub-clusters based on their global expression profiles. GO enrichment analysis indicated that numerous DEGs were associated with catalytic activity, cell cycle control, and the ribosome. KEGG enrichment analysis showed that the main pathways under Cd stress were MAPK signaling, oxidative phosphorylation, pyruvate metabolism, and propanoate metabolism. In addition, several DEGs encoding ion transporters, enzymatic/non-enzymatic antioxidants, and transcription factors were identified. Based on these results, a preliminary gene regulatory network was firstly proposed to illustrate the molecular mechanisms of Cd detoxification in M. spongiola. These results provide valuable insights into the Cd tolerance mechanism of M. spongiola and constitute a robust foundation for further studies on detoxification mechanisms in macrofungi that could potentially lead to the development of new and improved fungal bioremediation strategies.

Purpose: This study aimed to explore and understand the health promoting behaviors of low-income overweight and obese women in Korea. Methods: Data were collected from 10 low-income overweight and obese women working at a community self-sufficiency center through semi-structured in-depth interviews. Individual interviews were conducted and transcribed. Deductive content analysis was done, using the MAXQDA program. Results: The health promoting behaviors practiced by low-income overweight and obese women were affected by intrapersonal, interpersonal, and organizational/ community factors. Six categories were identified and two category clusters were derived that could best describe their health promoting experiences. As main category clusters, despite "feeling that the body and mind are not healthy" participants noted "difficulty maintaining a healthy lifestyle." Overall, the participants had poor nutritional status, lacked physical activity, experienced much stress in intrapersonal level, and faced intrapersonal-level barriers to health promoting behaviors. Moreover, participants had a lack of personal will, and lack of specific information to practice health promoting behaviors, a lack of time, and too many overall burdens to earn a living for their family while trying to maintain health promotion behaviors. Conclusion: Lifestyle interventions for nutrition management, encouragement of physical activity, and stress management are needed for overweight and obese low-income women. In addition, social support and policies are needed to improve their living environment.

Variations in phenotypic traits are important for onion genetic improvement. The aim of this study was to identify the phenotypic traits of temporary genetic resources and the best accessions for the development of onion breeding programs. Sixteen phenotypic traits of 79 onion accessions were studied. The descriptive statistics of phenotypic traits exhibited a high variation in onion accessions. Among the 79 evaluated accessions, 64.55% had a large bulb neck width and 44.30% had a circular bulb shape. Principal component analysis showed that six principal components (PCs) accounted for 72.65% of the total variation. The main factors contributing to PC1 were bulb weight, equatorial and bulb polar diameters, plant height, and degree of splitting into bulblets, whereas those contributing to PC2 were the bulb color of the epidermal cells of the fleshy scales and color of the dry skin on the bulb. The accessions were classified into three groups-clusters 1, 2, and 3. Cluster 2 accessions were the most suitable for selecting large and circular bulb-shaped onion cultivars. The phenotypic variation observed in this study may help to select potential accessions for breeding new onion cultivars.

Welded hollow spherical joints are commonly used joints in space grid structures. An internal stiffener is generally adopted to strengthen the joints when large hollow spheres are used. To further strengthen it, external stiffeners can be used at the same time. In this study, axial compression tests are conducted on four full-scale 550 mm spherical joints. The failure modes and strengths of the tested joints are investigated. It shows that the external stiffeners are able to increase the strength of the joint up to 25%. A numerical model for large spherical joints with stiffeners is established and verified against the experimental results. Parametric studies are executed considering six main design factors using the verified model. It is found that the strength of the spherical joint increases as the thickness, height and number of the external stiffeners increase, and the hollow sphere's diameter has a neglectable effect on the enhancement caused by the external stiffeners. Based on the experimental and numerical results, a practical formula for the compressive bearing capacity of large welded hollow spherical joints with both internal and external stiffeners is proposed. The proposed formula gives a conservative prediction on the compressive capacity of large welded hollow spherical joints with both internal and external stiffeners.

Temperature is one of the important factors affecting the permeability of water in the soil. In the present study, the impact of water temperature on hydraulic conductivity (k) with and without coarse aggregations by considering six types of soils was analyzed. Moreover, the effect of sand and gravel presence in the soil was investigated through the infiltration based on constant and inconstant water head experiments. Results indicated that by increasing the water temperature, adding gravel to sandy soil caused the hydraulic conductivity to raise. It is supposed that the gravel decreased the contact surface between the water and the soil aggregates. It is deduced that due to decreasing kinetic energy, k tends to have lower values. Furthermore, adding the sand to sandy silt-clay soil showed that the sand did not have a marginal effect on the variation of k since the added sand cannot increase the contact surface like gravel. Finally, increasing the main diameter of the soil will increase the effect of the water temperature on hydraulic conductivity.

This study was performed to assess the practice behavior and the need for cancer screening in order to design the community projects in Suwon city. A random sample of urban married women was surveyed on knowledge, attitude, and practice of breast and cervical cancer screening by telephone from April 28th to May 19th. Four hundred two married women completed the questionnaire, and the results were as follows: 1. Urban women were not generally knowledgeable about symptoms, signs and etiology of breast and cervical cancer. Only 11.4% of respondents were fully aware of those subjects. 2. Two hundred eighty six repondents(71.1%) reported having had a mammogram or Pap smear, while 116 respondents(28.9%) reported never having had a mammogram nor Pap smear. 3. The rate of mammogram increased by age and income status significantly(p〈0.05). 4. The majority(73.1%) of women who had a mammogram reported that it was part of a routine physical examination and another 24.3% of the women reported that they had a mammogram for specific breast problems. Meanwhile, the reasons reported for never having a mammogram were as follows; never had any problems (72.1%), no chance(11.2%), no time(4.3%). 5. The main factors associated with adherence to mammography screening guidelines was monthly income status. 6. The majority(80.6%) of women who had a Pap smear reported that it was part of a routine physical examination and another 16.0% of the women reported that it was part of a routine physical examination and another 16.0% of the women reported that they had a Pap smear for specific uterus problems. Meanwhile, the reasons reported for never having a Pap smear were: never had any problems(69.0%) and no chance(11.5%) 7. Women with higher income status were most likely to have a Pap smear regularly (p〈0.01), and the rate of Pap smear increased by education level significantly(p〈0.05). The main factors associated with adherence to Pap smear screening guidelines were education level and monthly income status, similar to those of mammograph. These findings indicate that married women in Suwon city show a lower rate of breast and cervical cancer screening practice than that of developed countries. The rate of mammograph was especially low. It is, therefore, suggested that cost, environmental factors, process, and information for screening tests be considered more programmatically before designing a community project for breast and cervical cancer screening.

본 연구는 우리나라 항만공사제도의 문제점을 인지하고 이에 따른 비효율을 제거하기 위한 방안으로 항만공사의 통합의도를 분석하였으며, 기업연합의 선행요인이 항만공사의 통합의도에 미치는 영향을 실증 분석하였다. 개별 항만공사에 재직 중인 내부 구성원을 대상으로 하여 항만공사의 기여도, 자율성, 전략요인, 재무요인, 마케팅요인, 환경요인 등 6개 통합의 선행요인이 항만공사의 통합의도에 미치는 영향을 실증적으로 분석하였다. 본 연구에서의 시사점은 크게 2가지로 나누어 볼 수 있다. 첫째는 항만공사의 지역이기주의, 항만 관련기관과의 불명확한 권한과 역할, 항만공사법상 사업다각화의 제한, 항만자치의 제한 등 구조적 문제점을 파악한 것이고, 둘째는 현행 항만공사체제를 유지하면서 비효율을 개선할 것인지 아니면 통합 항만공사체제로 전환할 것인지에 대한 논의의 전개다. 본 연구에서는 항만공사의 비효율을 극복하기 위한 방안으로 내부 구성원을 대상으로 통합의도에 대한 분석을 실시하였는데, 각 항만공사의 통합의도는 전체적으로 낮게 나타났으며, 조직차원으로 살펴보아도 전략요인, 재무요인, 마케팅요인, 환경요인 등 각 요인에 따라 통합의도에 정(+)의 영향을 미치는 경우와 부(-)의 영향을 미치는 경우 등 다양하게 나타나 본 연구에서 통합에 대한 결론을 맺는 것은 성급한 판단이라 생각된다. 다만 급격한 통합 항만공사체제는 효율성을 제고 할 수 없을뿐더러 각 지역별 항만공사의 특성을 잘 살릴 수 있다고도 할 수 없다. 따라서 항만공사의 통합에 대한 논의는 더욱 다양한 관점에서 지속되어야 할 것으로 판단된다. 본 연구의 결과는 항만공사의 통합을 위한 기초 자료로 활용될 수 있을 것이며, 현행 항만공사제를 유지한다 하더라도 본 연구에서 언급한 우리나라 항만공사제도의 문제점을 통해 우리나라 항만공사의 발전전략을 수립하는 데에 기여할 수 있을 것으로 사료된다.
