The purpose of this study was to establish the theoretical view for the analysis of the aesthetic characteristics of dress from the viewpoint of oriental aesthetics. Also, this study examined the universality and particularity of aesthetic characteristics in Korean and Japanese women's traditional costumes. To establish the theoretical view for the aesthetic analysis of dress from the viewpoint of oriental aesthetics, this study examined the relationship between the internal spirit of human, culture and the external form of dress. Based on this consideration, the viewpoints for the analysis of dress formation were the 'Form' as the basic structure of the external formation of dress and 'the Ornamentation' as the emphasis of the artistic characteristics of dress. The common world view shared by Korea and Japan holds the thinking system that everything is created from 'not to bee(無)' to 'being(有)'. This view emphasizes the totality and circulation of energy called 'Ki(氣)'. According to this view, oriental culture has been developed by intuition and pleasure called 'Heung(興)'. Therefore, the form of the oriental culture includes ambiguity and emphasizes the total harmony. These characteristics appeared in dress as the design of ambiguity, asymmetry and concealment. The meaning of the ornamentation in oriental world was the unified harmony of diversity and the colors and patterns of oriental dress were used by the symbolic meaning of Yin-Yang & Wu-Shing (陰陽五行)s principles. On the basis of the world view of the Ki, Korean and Japanese women's traditional costumes commonly shared the aesthetic values of concealment, emptiness, and symbolism. Also, their costumes expressed the difference, especially in the ornamentation. Korean costume expressed the beauty of simplicity and naivety, and Japanese costume expressed the beauty of ornamentation and nonornamentatIon.

A process control graphic system is proposed as an efficient tool for monitoring the operation of power plant. It uses the multi-processor structure with 60 Kbyte shared memory as an implemental type of the distributed computer system, so that it is flexible, functionally extensible, and applicable to real-time process. The shared memory is used as a real-time database handling the process values and operator's commands. The database files, generated by the user-interactive graphic editor developed for the system or text editor, have the characteristics of simplicity and user-friendliness. The process control graphic system, that can monitor the operation of boiler and function as a backup controller in case of failure in boiler controller, is applied to Ulsan power plant. As a result, it displays the operating data of the boiler process without error by 14 pages of color graphic image according to the operation menu, and additionally functions well as a fault-tolerant control system.

Professional ethics has received relatively little attention from scholarship in comparison with its practical needs. Professional ethics as an independent study of ethics is still underdeveloped in the sense that there is no theoretical unity. The purpose of this article is to lead to the fundamental importance of the professional ethics. More specifically, this article aims at clarifying the unified view of professional ethics through the detailed analysis of professionalism. Therefore, The main themes of this article are professionalism, conflicts between duties of professional roles and those of ordinary morality, the boundary of professional authority, the foundations of professional values and obligations, and the character of professional responsibility. The conclusion which is drawn from this study can be briefly stated as follows. Professionalism is an important social category, and professional should not isolate themselves from the public sphere. Thus, professional ethics that contains positive ethical standards should be built upon the basis of 'shared responsibility' which stimulate professional's moral commitment and institutional improvement.

In this paper, we examine the roles, mutual relationships, and guidelines for a healthy life as exemplified by the characters Santiago and Manolin in Ernest Hemingway's novel "The Old Man and the Sea" and use this content to compare the happy home life of elderly couples in Korea. Through a metaphorical exploration of the lives of elderly husbands and wives in Korean society, the study examines their significance as the core of the family, particularly during their senior years. Ernest Hemingway's "The Old Man and the Sea" portrays Santiago as a unique embodiment of virtue and humanity. As an elderly male fisherman, he symbolizes a profound connection with the sea, as well as qualities such as courage, patience, and unwavering passion. His story underscores the importance of pursuing new goals and maintaining hope even in old age. The relationship between Santiago and Manolin provides insights into the dynamics of elderly husbands and wives in their domestic lives. Manolin's unwavering support for Santiago and his understanding of Santiago's dreams exemplify the significance of mutual support and the establishment of common goals for elderly couples. These characters serve as exemplary models for understanding and supporting one another within a family setting. Within the context of family life, applying these exemplary models and relationship dynamics fosters mutual respect, collaboration, emotional expression, and effective communication. Supporting each other and working towards common goals can enhance the family atmosphere, resolve conflicts, and enrich domestic life. Furthermore, when elderly couples share common goals and enjoy activities together, they strengthen their bond and create a more fulfilling family life. These shared activities deepen the affection between elderly husbands and wives and contribute to a thriving household. Through the characters of Santiago and Manolin in "The Old Man and the Sea," we present in this study a deeper understanding of the values and roles within the domestic lives and affection of elderly husbands and wives. Mutual respect, collaboration, emotional expression, communication, mutual support, common goals, hope, and shared domestic activities all play pivotal roles in maintaining a healthy family life and establishing happiness and well-being within the family. We expect this study to offer valuable insights into the fields of family studies, elderly welfare, and sociology.

Purpose: At the end of life, communication is a key factor for good care. However, in clinical practice, it is difficult to adequately discuss end-of-life care. In order to understand and analyze how decision-making related to life-sustaining treatment (LST) is performed, the shared decision-making (SDM) behaviors of physicians were investigated. Methods: A questionnaire was designed after reviewing the literature on attitudes toward SDM or decision-making related to LST. A final item was added after consulting experts. The survey was completed by internal medicine residents and hematologists/medical oncologists who treat terminal cancer patients. Results: In total, 202 respondents completed the questionnaire, and 88.6% said that the decision to continue or end LST is usually a result of SDM since they believed that sufficient explanation is provided to patients and caregivers, patients and caregivers make their own decisions according to their values, and there is sufficient time for patients and caregivers to make a decision. Expected satisfaction with the decision-making process was the highest for caregivers (57.4%), followed by physicians (49.5%) and patients (41.1%). In total, 38.1% of respondents said that SDM was adequately practiced when making decisions related to LST. The most common reason for inadequate SDM was time pressure (89.6%). Conclusion: Although most physicians answered that they practiced SDM when making decisions regarding LST, satisfactory SDM is rarely practiced in the clinical field. A model for the proper implementation of SDM is needed, and additional studies must be conducted to develop an SDM model in collaboration with other academic organizations.

In recent years, the importance of managing software defects in the implementation stage has emerged because of the rapid development and wide-range usage of intelligent smart devices. Even if not a few studies have been conducted on the prediction models for software defects, their outcomes have not been widely shared. This paper proposes an efficient probabilistic management model of software metrics based on the Bayesian network, to overcome limits such as binary defect prediction models. We expect the proposed model to configure the Bayesian network by taking advantage of various software metrics, which can help in identifying improvements for refactoring. Once the source code has improved through code refactoring, the measured related metric values will also change. The proposed model presents probability values reflecting the effects after defect removal, which can be achieved by improving metrics through refactoring. This model could cope with the conclusive binary predictions, and consequently secure flexibilities on decision making, using indeterminate probability values.

Two forms of glucoamylase (GI and GII) from starch-grown Lipomyces kononenkoae CBS 5608 mutant were purified to apparent homogeneity by means of ultrafiltration, Sephacryl S-200 gel filtration and DEAE Sephadex A-50 chromatography. The apparent molecular weight was calculated as ca. 150 kDa for GI and ca. 128 kDa for GII, respectively. Both enzymes were glycoproteins with isoelectric points of 5.6 (GI) and 5.4 (GII). They had a pH optimun of 4.5 and were stable from pH 5 to 8. The temperature optimum for both enzymes was $60^{\circ}C$, but they were rapidly inactivated above $70^{\circ}C$. The $K_m$ values toward starch were estimated to be 6.57 mg per ml for GI and 4.52 mg per ml for GII, and the $V_{max}$ values were 16.28 ${\mu}M$ per mg for GI and 32.25 ${\mu}M$ per mg for GII, respectively. The $K_m$ and $V_{max}$ values of GII for ${\alpha}-$ or ${\beta}-cyclodextrin$ were estimated to be 0.15 mg per ml and 2.0 mg per ml, respectively ($K_m$) and 1.02 ${\mu}M$ per mg or 1.02 ${\mu}M$ per mg, respectively ($V_{max}$). Neither enzyme exhibited pullulanase activity but they released only glucose from starch or cyclodextrin. Amino acid analysis indicated that both glucoamylases were enriched in proline and acid amino acids. Glucoamylase GII strongly cross-reacted with a monoclonal antibody raised against GI enzymes, and the two enzymes shared very similar amino acid composition. Western blot analysis indicated that L. kononenkoae CBS 5608 mutant produced two forms of glucoamylase on starch, and that synthesis of them was subject to glucose repression.

This study empirically examines the impact of firms' environmental (E), social (S), and governancial (G) factors on their short-term and long-term values. To measure firms' non-financial performance, we use ESG performance grades published by KCGS (Korea Corporate Governance Service). We employ stock log return as the proxy of each firm's short-term value, and Tobin's Q ratio as that of its long-term value. From a series of regression analyses, we find each of the ESG factors generally has a negative impact on stock return while it has a positive impact on the Tobin's Q ratio. These results imply that firms' effort for enhancing their non-financial performance may adversely affect their financial performance in a short term; but in the long-term point of view, firms' values increase through their good images engraved by their respective social, environmental and governancial efforts. In addition, we compare the relative strength of impact among E, S, G, the three non-financial factors on the firms' value measured in Tobin's Q ratio, and find that S (social factor) and G (governancial factor) give statistically significant impact on the firms' value respectively. This result tells us it would be advised to strategically embed CSV (creating shared value) pursuing both of profits and social responsibility in the firms' future agenda. While E (environmental factor) is shown to be an insignificant factor for the firms' value, it should be emphasized as a major concern by all the stakeholders in order to form a sound business ecosystem.

The objective of this study was to evaluate the flood control capacity of the agricultural reservoir based on state-of-the-art climate change scenario - SSP (Shared Socioeconomic Pathways). 18 agricultural reservoirs were selected as the study sites, and future rainfall data based on SSP scenario provided by CMIP6 (Coupled Model Intercomparison Project 6) was applied to analyze the impact of climate change. The frequency analysis module, the rainfall-runoff module, the reservoir operation module, and their linkage system were built and applied to simulate probable rainfall, maximum inflow, maximum outflow, and maximum water level of the reservoirs. And the maximum values were compared with the design values, such as design flood of reservoirs, design flood of direct downstream, and top of dam elevation, respectively. According to whether or not the maximum values exceed each design value, cases were divided into eight categories; I-O-H, I-O, I-H, I, O-H, O, H, X. Probable rainfall (200-yr frequency, 12-h duration) for observed data (1973~2020) was a maximum of 445.2 mm and increased to 619.1~1,359.7 mm in the future (2011~2100). For the present, 61.1% of the reservoirs corresponded to I-O, which means the reservoirs have sufficient capacity to discharge large inflow; however, there is a risk of overflowing downstream due to excessive outflow. For the future, six reservoirs (Idong, Baekgok, Yedang, Tapjung, Naju, Jangsung) were changed from I-O to I-O-H, which means inflow increases beyond the discharge capacity due to climate change, and there is a risk of collapse due to dam overflow.

Objectives: The purpose of this study was to compare the first echo boomer to second in the needs for family strengths and family functions, after controlling the sociodemographic characteristics. Method: For this study, a survey was conducted with 406 never-married young adults, which has 182 first echo boomers and 224 seconds echo boomers as using the same self-report questionnaire. Results: First, the two echo boomer groups exhibited similar patterns in their perception of the three family strengths, positive family values, pursuit of coexistence, and spiritual value, in that order. On the other hand, in regard to family functions, groups' perceived emotion entertainment leisure function as core functions of the family, but the second echo boomers, unlike the first echo boomers, expressed a higher need for economic functions rather than functions for children generation. Second, the analysis of this study indicated that, even in cases where first and second echo boomers had the same social-demographic characteristics, the latter in contrast with the former tended not to regard spiritual values such love for shared ethical values, compassion, and religious beliefs as a family strength, and did not require functions for children generation of the family. Conclusions: From these findings, the differences in the needs for family strengths and functions expressed by the two generations belonging to two different birth cohorts were influenced by various changes in Korean society occurring between the two generations, such as the social divergence in the functions of care and nurture, the increase in one-person and childless households, and the weakening of kinship-centered or communitarian forms of familism.
