In Korea, the collapse of traditional Patriarchal family system has caused the weakening the patriarchal authority which represents the decrease of traditional attitude of respect for old age, influenced by the strong tendency of Materialism in ethics. The urgent problem is how to solve the conflicts of the alienation almost every old people has felt from the society and family which they belong to and how to harmonize the respect for old age who used to have had in the past. From 21st to 30th of July 1979, I explored the small village in Cheju Island with eight students which I selected on purpose that village had preserved the traditionalism. I collected the interview data form a sample of 221 persons of the village in Cheju Island. I studied this small village in Cheju Island for the intention of suggesting the ideal model of regional society which both traditional and non-formal, although the phenomena of nuclear family system and materialism and industrialism are overwhelming in ur present society. Generally people in Cheju Island are economically poor and major occupation is farming, since the industrialization proceeds very slowly and there still strongly remains the traditionalism. Alienation and dissatisfaction of old people from their family and society in Cheju island are less common in comparison to the main land. Old people in Cheju Island usually value the importance of labour. Divison of labour has been well observed in farming, and men and women in Cheju island are equally regarded in comparison to the main land. Old people are independent economically and spiritually from their offsprings and they organize the nuclear family system firmly. Also the old generation is ready to compromise with the new generation and they defy the authoritariansim.

This study was designed to determine the best cultivar of kohlrabi for making pickles among KM-1 (Worldcol), KM-2 (Bejo), KM-3 (Takii), and KM-4 (Monsanto) cultivars. The initial pH of pickles was different in all cultivars; however, they all had a pH in the range of 3.81~3.86 after 28 days of storage. The pickles made from KM-4 had the lowest acidity, while there was no significant difference in acidity among the KM-1, KM-2, and KM-3 pickles. The salinity of all kohlrabi pickles was consistent during the storage period. The changes of color values were accelerated in the following order: KM-4>KM-1>KM-2>KM-3. Though kohlrabi pickles were non-fermented, the change in reducing sugar contents was similar to that of a fermented pickle. The highest value of reducing sugar content was found in pickles made with KM-4. In all cases, the firmness of the pickle decreased as time of storage increased. On the initial day, KM-4 pickle showed the highest firmness with 807.4 g. KM-4 also showed the highest firmness on the 28th day of storage with 602.3 g. In sensory evaluation, the KM-4 pickle exhibited the highest texture (hardness) among the pickles. The pickle made with the KM-4 cultivar showed relatively higher firmness of texture than other cultivars, suggesting that KM-4 could be utilized in other kinds of processed foods, in addition to being pickled.

To explore the application of traditional tuned mass dampers (TMDs) to the earthquake induced vibration control problem, a pounding tuned mass damper (PTMD) is proposed by adding a viscoelastic limitation to the traditional TMD. In the proposed PTMD, the vibration energy can be further dissipated through the impact between the attached mass and the viscoelastic layer. More energy dissipation modes can guarantee better control effectiveness under a suite of excitations. To further reduce mass ratio and enhance the implementation of the PTMD control, multiple PTMDs (MPTMD) control is then presented. After the experimental validation of the proposed improved Hertz based pounding model, the basic equations of the MPTMD controlled system are obtained. Numerical simulation is conducted on the benchmark model of the Canton Tower. The control effectiveness of the PTMD and the MPTMD is analyzed and compared under different earthquake inputs. The sensitivity and the optimization of the design parameters are also investigated. It is demonstrated that PTMDs have better control efficiency over the traditional TMDs, especially under more severe excitation. The control performance can be further improved with MPTMD control. The robustness can be enhanced while the attached mass for each PTMD can be greatly reduced. It is also demonstrated through the simulation that a non-uniformly distributed MPTMD has better control performance than the uniformly distributed one. Parameter study is carried out for both the PTMD and the MPTMD systems. Finally, the optimization of the design parameters, including mass ratio, initial gap value, and number of PTMD in the MPTMD system, is performed for control improvement.

In the cultural realm of Hinduism centering around India, traditional costumes such as Sari, and Dhoti are worn up to date under the influence of religious faith, tradition, and fundamentalism. The purpose of this study is to clarify the religious meaning of unstitched traditional Indian costume and inquire into the figurative beauty of it. This study revolved around India, and the aesthetic feature affected by hinduism was examined based on the literature references and the figurative feature and aesthetic value of unstitched costume were analyzed. The most important feature of Indian costume is the unstitched costume without joining pieces of cloth by using a needle and thread, symbolizing the purity based on the cosmology of Hindu. In the unstitched costume of India, natural drapery that is the large cloth, slipped or tied on body, wrapping it affluently, is emphasized. Unstitched costume of India, based on cosmology of Hindu and the concept of purity, is still broadly worn by people under the influence of fundamentalism and conservative atmosphere. Religious idea is expressed and a beauty of concealment, emphasizing the chastity, is shown in the unstitched costume of India, while a beauty of nature is distinctively revealed in the non-structural and asymmetric drapery costume due to the unique wearing style. In addition, 'A beauty of symbolism' appears in the wearing method, color, the part of wearing, and ornament. Religion has affected overall culture that is inclusive art, aesthetics, and social structure and has contributed to the formulation of costume style. Unstitched costume of India is the unique tradition of India and identity, based on the religious idea.

Background: One of the important actions for enhancing human reliability in any industry is assessing human error probability (HEP). The HEART technique is a robust tool for calculating HEP in various industries. The traditional HEART has some weaknesses due to expert judgment. For these reasons, a hybrid model is presented in this study to integrate HEART with Best-Worst Method. Materials Method: In this study, the blasting process in an iron ore mine was investigated as a case study. The proposed HEART-BWM was used to increase the sensitivity of APOA calculation. Then the HEP was calculated using conventional HEART formula. A consistency ratio was calculated using BWM. Finally, for verification of the HEART-BWM, HEP calculation was done by traditional HEART and HEART-BWM. Results: In the view of determined HEPs, the results showed that the mean of HEP in the blasting of the iron ore process was 2.57E-01. Checking the full blast of all the holes after the blasting sub-task was the most dangerous task due to the highest HEP value, and it was found 9.646E-01. On the other side, obtaining a permit to receive and transport materials was the most reliable task, and the HEP was 8.54E-04. Conclusion: The results showed a good consistency for the proposed technique. Comparing the two techniques confirmed that the BWM makes the traditional HEART faster and more reliable by performing the basic comparisons.

Rapid social changes and scientific advances of the $21^{th}c$ have brought on a major paradigm shift towards consilience, making boundaries more or less irrelevant. In the field of architecture, this is manifested in the emergence of colors that can be described as 'being aleatory', 'non-formal', 'non-deterministic' and 'perpetually evolving'. Contemporary architectural colors are not definitively fixed. They are rather liquid and metaphorical. Whereas the more traditional architectural colors have delivered clearly and precisely the intended symbolic meaning and visual information, those of today are less definitive and embody a more liquid and conceptual value system. This paper discusses the denoted signification and the meaning effect of the metaphorical color system found in contemporary architecture. This paper analyzes works of architecture from the late 20th century, when dramatic change sin architectural color system surfaced, to the more contemporary creations. Here, three categories of color are suggested, namely material color, spatial color and liquid color. Each categories considered in connection with deconstruction, holistic interactivity and the multiplicity of meanings that may result as information from the external world is perceived as stimulus to the inner mind. Contemporary architectural color scheme is characterized by its unpredictable vagueness of meaning, synesthetic engagement of imagination and chance, and expansion of the inner and outer world, all of which contribute to a metaphorical effect. The metaphorical color system of contemporary architecture can be classified into three dimensions, and it connects with human consciousness and amplifies itself through flexible and fluid communication. In this process non-physical colors materially serve as formal logic and room for varied interpretation of architectural space and our conceptual framework.

대체불가능 토큰(non-fungible token, NFT)은 제작 이후의 내역을 신뢰성 있게 관리할 수 있다는 장점이 있으나 NFT의 창작자를 직접적으로 보호하기 어렵다는 문제가 있다. 창작자의 고유한 아이디어는 어떻게 보호할 수 있을까? 디지털 자산의 가치를 높이기 위한 NFT 활용은 증가하고 있으나 창작자의 동의 없이 NFT가 생성되고 판매되는 문제 또한 늘어나고 있다. 기존의 창작자 보호 방법으로 전통적 인증 시스템을 사용하는 방법과 소셜 네트워크를 사용하는 방법이 제안되었으나 각각의 한계점이 존재한다. 본 연구에서는 새롭게 정체성 토큰(identity token)을활용하는 방법을 제안하여 기존의 한계점을 보완하고자 한다. 정체성 토큰을 사용하여 공신력을 높이고 법적 분쟁에 대응하여 실제 창작물의 귀속문제를 해결함으로써 창작물 NFT의 거래를 활성화할 수 있을 것으로 기대한다.

Purpose - Recently, the number of corporations that practice environmental and social responsibility, besides engaging in traditional profit-seeking activities, has been growing steadily, as interest in Corporate Social Responsibility (CSR) is increasing. Recent research on CSR practices has identified the relationship between CSR activities and corporate value as one of the main issues in this respect. Considering that donations constitute a large proportion of a company's charitable activities, we considered the extent of donation expenses as a charitable activity in order to mitigate sample selection bias. Specifically, we analyzed the impact of donation expenses on firm value, while investigating if this impact varied in response to the level of corporate governance of firms. Research design, data, and methodology - We used non-financial firms listed on the Korean Stock Exchange, having their fiscal year end in December, and the sample period was 2006-2013. For the dependent variable, Tobin's q was used as the corporate value, and for the independent variable, donations were measured as the donation-expense-to-sales ratio. Corporate governance scores, as rated by the Korea Corporate Governance Service, were used to measure corporate governance levels because they consider the overall aspects of governance, including ownership structure, the board of directors, and the audit mechanism of individual companies. To examine the impact of donations on a company in relation to the level of corporate governance, we estimated regression models using the interaction terms of the governance dummy and donation variables. Then, we further estimated the regression models of two sub-samples that were classified according to the level of corporate governance. Similar to previous studies, the study uses variables that affect firm value, such as R&D expenditure, advertising expenses, EBITDA, debt-to-equity ratio, sales growth, company age, and company size as control variables. Results - The empirical results show that firm value significantly increased in response to an increase in donation expenses. Upon including the interaction terms of governance level dummy variables and donations, the coefficients of the interaction terms show significant positive values, while those of donation variables show significant negative values. In the strong governance sub-sample, the relationship between the donation expenses and corporate value was statistically positive (+) and significant. However, in the weak governance sub-sample, the relationship between the donation expenses and corporate value was statistically insignificant and negative (-). Conclusions - The empirical results suggest that donation expenses are significantly linked to an enhanced corporate value if firms have a good corporate governance structure. However, if the corporate governance structure is weak, the same relationship is not necessarily observed. The results of this study show that if a firm has high corporate governance, CSR practices enhance the company's reputation such that it has a positive (+) relationship with corporate value. If a firm has weak corporate governance, on the other hand, CSR practices are recognized as an agency cost and do not increase corporate value.

The aims of this study were to develop and standardize the manufacturing procedures and ingredient formulation of non-fried, extrusion-puffed Yukwa. The quality and storage stability of the non-fried Yukwa (NF) were characterized and compared against a traditional deep-fried Yukwa (F). The moisture contents of both the NF and F were almost comparable at 5.12${\sim}$6.22% after the final product preparation. The textural hardness values of the NF samples were one-half to two times as hard as those of F, although no clear distinctions were reported between the two products by the sensory evaluation results (p<0.05). During storage, the acid value of F was 1.68 KOH mg/g on day 7, and then it rapidly increased to 5.52 KOH mg/g on day 14. In contrast, the acidity values of NF were 1.21 and 2.62 KOH mg/g on day 7 and 14, respectively. The peroxide values of the samples increased from 23.5 to 62.0 meq/kg (F) and from 2.0 to 2.5 meq/kg (NF) during the two weeks of storage after preparation, suggesting excellent fat stability for the NF product. Regarding the sensory evaluation results of the products, no significant (p<0.05) differences were noted between F and NF with scores of approximately 3.1 out of 5.0 points for the overall quality characteristics of the final products. Accordingly, we conclude that extrusion puffing technology could be adopted as an alternative to conventional deep fat frying as a partial manufacturing process of Yukwa.
