This study is basically to investigate the possibility of revitalizing the fishing village economy by targeting on trip type, propensity, and awareness of visitors who visited Gogunsan in JeonBuk by applying Blue Amenity. As the result of survey, it showed that visitors in Gosunsan islands generally were satisfied with trip, and they had considerably higher intention of revisit. However, it showed that the improvement and publicity of various travel services including resources and facilities were demanded. In particular, it should pay attention to requirements depending on age and selection of main visitors with reference to revisit, and as the result, the factors having the most important influence on are traffic, and natural scenery, so it is considered that these factors must be maintained to increase the rate of revisit with full of concentration. Besides, it is confirmed that Visitors are unfamiliar with Blue Amenity applying fishing village's own historical cultural resources with reference to preferring islands trip, and they were much concerned about the establishment of tentatively named "regional(urban - fishing village) center" to revitalize the fishing village economy. Moreover it could grasp the tourist industry operated jointly by fishing villages, the pride of town to characterize, advantage in promoting the tourist industry as compared with other regions, and difficulties or recommendations in promoting the tourist industry. And comprehensive investigation of Blue Amenity resources in this region and the measures of improving life environment must be performed in future.

The purpose of this study is to find out how to empower the community in developing Unique Javanese Agro Tourism in the Klaten regency, Central Java Indonesia. Community economic empowerment is carried out by 1) conservation-based development, namely the pattern of community development while maintaining the authenticity of ecosystems by seeking to preserve natural, historical, cultural, and recreational natural resources. Community development can be done in stages, that is, carried out before the area becomes an object of agro-tourism and after the area becomes an object of agro tourism, 2) Community empowerment in the development of unique Javanese agro-tourism can be done with the development of community-based agro-tourism, intended to pattern community development that places agrotourism as empowering farmers to obtain good value from agricultural products as well as from tourist visits; the dual effect of absorption of agricultural products by tourism businesses and developers of agro-tourism areas/regions; by the government as an area to develop agrotourism; synergy between communities; and the role of tourism institutions and agricultural institutions in fostering agro-tourism so that this can enhance the aesthetic value and beauty of nature.

This paper is an art historical attempt to discuss the transfer and transmission of a certain visual idiom along the Silk Roads and to show the multi-dimensionality of the trans-regional, trans-cultural movement. The motifs of grapes and grapevines are discussed here for this purpose, including the grape-and-vine motif mixed with other animated figures and plants. A special emphasis is on China and its reception, but regional varieties within East Asia are also discussed. The motif is one of the most longstanding and versatile visual idioms, widely distributed along the regions of the Silk Roads. This deceptively familiar motif came to China, where grapes and viticulture were introduced far later than the West. The West developed various symbolisms ranging from manic revelry and heavenly unity with mystic beings, to royalty and power in different cultures. In China, this visual idiom was eagerly received in association with something exotic and re-interpreted in the context of Chinese culture. Without active viticulture, the motif transformed itself into beautiful design patterns and space fillers in China and East Asia. The natural appeal of jewel-like grapes acquired new meanings of fertility and happiness in the traditional East Asian cultural context. To see the cultural effect of viticulture on the visualization of this motif, the Islamic reception of the motif is briefly touched upon when countries to the West of China (서역 西域) were fully Islamized and heavily affected by the prohibition of alcoholic drinking.

The influence of water temperature (WT) on air temperature (AT) in the eastern and western coastal regions of the Korean peninsula in the winter was investigated using historical data from the Korean Meteorological Agency (KMA) and the National Institute of Fisheries Science (NIFS), focusing on the relationship between AT and WT. The data analysis shows that, during winter, the AT is generally higher by +1.9 to $+2.7^{\circ}C$ at Kangreung ($37.2^{\circ}N$) in the eastern region than at Inchon ($37.4^{\circ}N$) in the western region, i.e., the AT in the eastern region of the Korean Peninsula tends to be higher overall than that in the western region when similar latitudes are compared. On the other hand, in the winters of 1977-2006, the WT at Sokcho was higher by $+0.8^{\circ}C$ (January) to $+2.3^{\circ}C$ (March) than that at Sochungdo, directly resulting in increased AT ($+1.22^{\circ}C$) at Sokcho. This study suggests that higher AT in the eastern region during winter is caused by the influence of water flow, such as the East Korean Warm Current in the East/Japan Sea.

Downtime and malfunction of industrial rotor machines represents a crucial cost burden and productivity loss. Fault diagnosis of this equipment has recently been carried out to detect their fault(s) and cause(s) by using fault classification methods. However, these methods are of limited use in detecting rotor faults because of their hypersensitivity to unexpected and different equipment conditions individually. These limitations tend to affect the accuracy of fault classification since fault-related features calculated from vibration signal are moved to other regions or changed. To improve the limited diagnosis accuracy of existing methods, we propose a new approach for fault diagnosis of rotor machines based on the model generated by supervised learning. Our work is based on feature residual values from vibration signals as fault indices. Our diagnostic model is a robust and flexible process that, once learned from historical data only one time, allows it to apply to different target systems without optimization of algorithms. The performance of the proposed method was evaluated by comparing its results with conventional methods for fault diagnosis of rotor machines. The experimental results show that the proposed method can be used to achieve better fault diagnosis, even when applied to systems with different normal-state signals, scales, and structures, without tuning or the use of a complementary algorithm. The effectiveness of the method was assessed by simulation using various rotor machine models.

During the COVID-19 pandemic, the obligatory wearing of masks has led to increased consumer demand and the diversification of mask design. Accordingly, it is necessary to understand the inner meaning and characteristics of masks in the pandemic situation. Therefore, the purpose of this research is to analyze the characteristics of fashionable masks and their new cultural meaning under the COVID-19 pandemic. This research is based on literature review and empirical research. Drawing on an investigation of the historical evolution of masks and their transition under the pandemic (exhibiting differences in mask culture among countries and regions), this study analyzed 54 distinctive fashion masks designed by fashion brands and influencers that appeared from January 2020 to January 2021. The characteristics of fashion masks identified under the influence of the pandemic are as follows: Message delivery on political issues and human rights; psychological defense and expression of individuality; and conspicuous display via luxurious materials and luxury brand logos; moreover, the design of the mask uses the same material, color, pattern, decoration, and other methods as clothing to achieve the overall style. Over the course of the pandemic (and even in post-pandemic lifestyle), fashion masks are becoming more diversified conveying new social and cultural meanings.

Tartan, the woven, checked, and wool textile considered by many to be originally from Scotland, has in fact been in use in a range of forms across numerous cultures and during various historical periods. The characteristic checked feature is due to the assembly of different coloured threads in both warp and weft directions which intersect at 90 degrees in a combination known as a sett. For well over one hundred years, different setts and thus different colour combinations have been associated closely with different geographical regions within Scotland, as well as different clans or families. Tartan-type textiles have reached popularity at various times and those have often been a predicted fashion trend suggested, for example, by contributors to fashion gatherings such as Premier Vision in Paris. Often proposed designs are best considered based on tartan combinations rather than simple reproductions. Promotional terms such as "patched checks" or "textured checks" have been common, and often these have been derived from tartan-type constructions. This paper explores novel pattern design methods by identifying the underlying grid structures and proportions exhibited by various well-known tartan setts. The possibility of pattern development from tartan grids and their manipulations is thus the focus of attention. An insight into the methodology associated with the production of original pattern designs is thus provided.

The comprehension and structural modeling of masonry constructions is fundamental to safeguard the integrity of built cultural assets and intervene through adequate actions, especially in earthquake-prone regions. Despite the availability of several modeling strategies and modern computing power, modeling masonry remains a great challenge because of still demanding computational efforts, constraints in performing destructive or semi-destructive in-situ tests, and material uncertainties. This paper investigates the shear behavior of masonry walls by applying a plane-stress FE continuum model with the Modified Masonry-like Material (MMLM). Epistemic uncertainty affecting input parameters of the MMLM is considered in a probabilistic framework. After appointing a suitable probability density function to input quantities according to prior engineering knowledge, uncertainties are propagated to outputs relying on gPCE-based surrogate models to considerably speed up the forward problem-solving. The sensitivity of the response to input parameters is evaluated through the computation of Sobol' indices pointing out the parameters more worthy to be further investigated, when dealing with the seismic assessment of masonry buildings. Finally, masonry mechanical properties are calibrated in a probabilistic setting with the Bayesian approach to the inverse problem based on the available measurements obtained from the experimental load-displacement curves provided by shear compression in-situ tests.

A study was conducted to analyze data from 1981 to 2020 for understanding the impact of climate on solar energy generation. A significant increase of 104.6 kWhm^-2 was observed in the annual cumulative solar radiation over this period. Notably, the distribution of solar radiation shifted, with the solar radiation in Busan rising from the seventh place in 1981 to the second place in 2020 in South Korea. This study also examined the correlation between long-term temperature trends and solar radiation. Areas with the highest solar radiation in 2020, such as Busan, Gwangju, Daegu, and Jinju, exhibited strong positive correlations, suggesting that increased solar radiation contributed to higher temperatures. Conversely, regions like Seosan and Mokpo showed lower temperature increases due to factors such as reduced cloud cover. To evaluate the impact on solar energy production, simulations were conducted using climate data from both years. The results revealed that relying solely on historical data for solar energy predictions could lead to overestimations in some areas, including Seosan or Jinju, and underestimations in others such as Busan. Hence, considering long-term climate variability is vital for accurate solar energy forecasting and ensuring the economic feasibility of solar projects.

라틴아메리카 대륙에서 안데스 산맥지역은 다양한 원주민종족 집단이 집중적으로 분포되어 있다. 이러한 종족 중에서 아이마라족은 케추아족과 함께 가장 대표적인 원주민 집단을 구성한다. 특히 티티카카호수를 중심으로 페루와 볼리비아 양국 접경지역에 밀집되어 있는 아이마라 원주민은 각각 국가의 소속을 달리하지만 하나의 삶의 터전 속에 동일한 문화권을 형성하며 공통의 정체성을 추구해 왔다. 그동안 아이마라 원주민은 종족의 정체성을 구성하는 언어를 바탕으로 다른 원주민 집단과 구분되는 역사성과 특수성을 강조하며 동일종족으로서의 유대감을 유지해왔다. 그러나 최근 들어 양국 접경지역의 중심지인 푸노(Puno)주를 중심으로 아이마라 원주민의 종족갈등이 표면화 되고 있다. 독립이후 근대국가 건설과정에서 형성된 인위적인 영토 경계선으로 분리된 이후 라틴아메리카 원주민은 협조와 경쟁이라는 틀 속에서 문화적 유사성과 동시에 차이를 강조하기 시작하였다. 이러한 역사적 맥락과 함께 최근 들어 페루와 볼리비아 접경지역을 중심으로 동일한 종족이 서로 다른 국가의 틀에 묶이면서 발생하는 새로운 종족 갈등이 전개되고 있다. 아이마라 원주민은 외부와의 경쟁에서 문화와 역사적 특수성을 강조하며 자신들을 하나의 단일한 종족으로 인식하며 단결하지만, 내부의 이해관계를 둘러싸고 충돌할 경우 서로가 문화적 전통을 상실했다는 비난을 가하며 종족 내부에서도 차별과 구별의 정체성을 형성하는 경향을 나타냈다. 종족간의 갈등은 한 지역에 공존하고 있는 타 종족간의 갈등에서 비롯되는 경향이 있으나 페루와 볼리비아 아이마라 원주민의 경우 양국이 접경을 유지하고 있는 푸노주를 중심으로 오랜 역사를 통해 형성된 종족의 유대감이 현실의 조건에 의해 갈등구조로 변화하는 양상을 타나내고 있다. 이러한 점에 착안하여 본 연구는 아이마라 원주민 종족갈등의 심화원인을 분석하였다.
