The distributions of common minke whales observed in the East Sea in ten surveys in May of 2003, 2005, 2006, 2007, 2009, 2010, 2012, 2015, 2016 and 2020 were investigated using satellite sea surface temperature (SST) derived from the Moderate Resolution Imaging Spectrometer (MODIS). Most of the minke whales were observed in the waters off the Korean Peninsula at 36-38.5° N, which is expected as the highly productive coastal upwelling area. Yet, no minke whale was observed in 2006 when a relatively larger scale coastal upwelling occurred with SST at 11℃. In 2016 and 2020, the warm water higher than 17℃ extended widely in the area, and the minke whales were observed in the offshore waters, deeper than 1,000 m. 87.5% of minke whales observed in May appeared in the SST from 13 to 16℃, and they seemed to avoid relatively high temperatures. This suggests that optimum habitat water temperature of minke whales in May is 13-16℃. The SST in the area had risen 1.67℃ from 2003 to 2021, and it was remarkably higher than in other parts of the surrounding areas. The future temperature rising may change the route and timing of the migration of minke whales in the study area.

Eco-village is emerging as one of housing styles in the modern age. The common space in Eco-village uses environment-friendly materials while residents appear to aspire to a community. The common space in Eco-village offers a place of interchange and interaction for both visitors and residents as a transit area connecting dwelling units. It also forms the sense of community and serves as a space that builds friendly relations among residents. However, there seems to be a lack of research compare to its various roles and importance for this common space, which is an significant factor in establishing Eco-village plans. The purpose of this study is to provide research data by creating a layout drawing of Eco-village and reveal the characteristics of space boundary and practical use of common space through case studies on villages. This will serve as actual data in designing common space which would correspond to the purpose of Eco-village planning.

The purpose of this study was to identify the relations among management for residents, sense of community and common space for residents which provided in high rise mixed-use residential building constructed at the end of 1990s. Research method was social survey with questionnaire from 178 subjects collected by the snow ball sampling. Statistical analysis was done by the SPSS 10 for Windows program using frequency, percentage, t-test, one-way ANOVA. Research results showed high degree of residents' management satisfaction in the area of fitness space and business service. And they also showed high degree of residents' satisfaction in common space which include swimming pool, shower and sauna facilities. Satisfaction degree of management for residents became high with the support of residents' common space, so the management of residents' common space might be important in the management of high rise mixed-use residential building. Finally, residents' management and residents' common spaces have an important role to enhance the sense of community.

This study set out to review the air current fluidity in exhaust common ducts by installing an inlet pipe at a leisure space in the PS(Pipe Shaft)room for the sake of wind power generation with kitchen and bathroom exhaust common ducts of all the equipment and air conditioning shafts in high-rise apartment. The air current functionality of kitchen and bathroom exhaust common ducts was reviewed by analyzing wind velocity changes according to changes to the area of exhaust common ducts through a simulation, changes to the wind velocity of the kitchen hood by applying an external inlet pipe, changes to the usage factor of exhaust common ducts, and changes to wind velocity by altering the form of the ventilator at the bottom of the old exhaust common duct. It was a basic study on the utilization of exhaust wind velocity in exhaust common ducts.

Background: Cervical cancer is one of the most common cancers among women worldwide, and in Thailand is the second most common cancer among women. In 2008, a national cervical cancer screening programme was implemented in Thailand, but coverage remains relatively low. Objectives: The purpose of the study was to investigate whether cervical cancer screening uptake is associated with the area of residency in Thailand. Materials and Methods: A case-control study was carried out in women aged 30 to 60 year-old, who live in Sikhiu district, Nakhon Ratchasima province, Thailand. Structured-questionnaires were used to interview 226 women (cases) who had attended cervical cancer screening in the last five years and 226 women (controls) who had not. Multiple logistic regression was used to investigate the association between the area of residency and cervical cancer screening uptake. Results: After controlling for parity, marital status and duration of hormonal contraceptive use, an association between the area of residence and cervical cancer screening uptake could not demonstrated ($OR_{adj}$ 1.27, 95%CI: 0.79, 2.04). Conclusions: We found no evidence to suggest remoteness to health care center led to lower cervical cancer screening uptake.

In out-patient clinic, it seems to be common that most back pain arise from muscular origins rather than from skeletal origins. Most physicians have wished to diagnose lower back pain from the radiologic findings only. From clinical experiences and anatomical studies, I have gotten a different opinion from common sense about backaches. If I met a patient who had lower back pain around the posterior superior iliac crest(P.S.I.C.) area, I would had to search a trigger point in the erector spinae muscles at the level of thoraco-lumber junction rather than at the level of the painful site. It is why that sensory innervation over the posterior superior iliac crest area is the posterior primary branch of T12 spinal nerve running down through the erector spinae muscles. Pain on the iliac crest area is supposedly due to hyperirritability of the sensory nerve distributing to this area. Hyperirritability of the posterior primary branch of $T_{12}$ spinal nerve may be due to the spasm of the longissimus thoracis muscle in the erector spinae muscles at the level of the thoraco-lumbar junction. So finally, I would like to insist that spasmolytic treatment on the muscle at the level of the thoraco-lumbar junction would be better for pain relief around P.S.I.C. than treatment at the painful site only.

A study was made on the change of vegetation in Yungil area after the erosion control works. The area was divided into three major areas, the devastated land area, the afforested area and the subclimax area. Two groups of plant, i.e., the common species in all area and the different species confined in the subclimax area, were identified by the interspecific correlation analysis based on the positive correlation value at 5% significance level. High similarity among the sites in the afforested region was indicated by the DIF (difference measure) value, lower than 0.33. However, the devastated area and the subclimax area were distinguished completely. The change in species diversity has been extremely low since the erosion control works. Robinia pseudo-acacia was the dominant species in the afforested region and showed an adequate growth status.

In this paper, we introduce and study an explicit hybrid relaxed extragradient iterative method to approximate a common solution to generalized mixed equilibrium problem and fixed point problem for a nonexpansive semigroup in Hilbert space. Further, we prove that the sequence generated by the proposed iterative scheme converges strongly to the common solution to generalized mixed equilibrium problem and fixed point problem for a nonexpansive semigroup. This common solution is the unique solution of a variational inequality problem and is the optimality condition for a minimization problem. The results presented in this paper are the supplement, improvement and generalization of the previously known results in this area.
