  • There are various reasons for missing values when collecting data. Missing values have some influence on the analysis and results; consequently, various methods of processing missing values have been studied to solve the problem. It is thought that the later point of view may be affected by the initial time point value in the repeated measurement data. However, in the existing method, there was no method for the imputation of missing values using this concept. Therefore, we proposed a new missing value imputation method in this study using clustering in initial time point of the repeated measurement data and the measure of property proposed by Kim and Kim (The Korean Communications in Statistics, 30, 463-473, 2017). We also applied the Monte Carlo simulations to compare the performance of the established method and suggested methods in repeated measurement data.

  • This study aimed to identify and analyze the attributes of FoMO, and to provide basic data for the intervention of FoMO in cancer patients. In order to confirm conceptual attributes, antecedents, and consequences by applying the conceptual analysis method of Walker & Avant (2010), 82 previous studies published from 2004 to 2021 were analyzed. The conceptual attributes were relative deprivation, social exclusion, lack of sense of belonging, lack of interaction with others, negative emotions, and the antecedents were a sense of alienation when you miss the flow or when excluded from activities and the desire to connect with others. The consequences of this were increased emotional distress, triggering negative emotions such as depression and anxiety, and decreased life satisfaction and self-esteem. The attributes of these FoMO were also confirmed in cancer patients. Based on this, it is necessary to develop an effective intervention program to improve FoMO in cancer patients.

  • This paper discusses the incompleteness of the SNOMED CT and proposes a noble metric which evaluates similarity among sibling nodes as a method to address this incompleteness. SNOMED CT encompasses an extensive range of medical terms, but it faces issues of ontology incompleteness, such as missing concepts in the hierarchy. We propose a noble metric for evaluating similarity among nodes within a node group, composed of multiple sibling nodes, to identify missing concepts, and identify groups with low similarity. Analyzing the similarity of sibling node groups in the March 2023 international release of SNOMED CT, the average similarity of 29,199 sibling node groups, which are sub-concepts of the clinical finding concept and are consist of two or more sibling nodes, was found to be 0.81. The group with the lowest similarity was associated with child concepts of poisoning, with a similarity of 0.0036.

The Effect of Animosity Type on Consumer Cognition and Consumption Behavior Direction : Based on the Moderating Role of Fear of Missing Out (국가간 적대감 유형이 소비자 인지와 소비행동 방향에 미치는 영향 : 고립공포감의 조절효과를 중심으로)

  • The purpose of this study aims to investigate how consumer awareness and purchasing behavior are affected by the type of animosity against the nation. This study classified animosity into three categories: sociocultural, economic, and war-based. Additionally, the consumer's cognition toward animosity was split into two categories-empathic concernt and personal distress-and the direction of consumption behavior was split into two categories-individual brand avoidance behavior and collective bandwagon behavior. The concept of Fear of Missing Out (FoMO) was introduced for the direction of consumption behavior, further validating the moderating impact. Structural equation modeling method was used to measure the general consumption behvior of Korean consumers' animosity. The results were analyzed using a total of 279 samples. As a result, animosity motivated by war and by economics had a substantial impact on empathic concern, while animosity motivated by socioculture had a significant impact on personal distress. Personal distress had a good impact on an individual's brand antipathy behavior, which in turn led to brand dislike and avoidance. Empathic concern also had a positive impact on the phenomena of group sympathy, which leads to identification of conduct and social conformity. Also, it was proven that the group that had a high level of FoMO reacted strongly to the phenomenon of group collective behavior.

  • In light-frame wood construction, missing roof-sheathing fasteners can be a relatively common occurrence. This type of construction makes up the vast majority of the residential building stock in North America and thus their performance in high winds, including hurricanes, is of concern due to their sheer number. Construction quality issues are common in these types of structures primarily because the majority are conventionally constructed and unlike steel and reinforced concrete structures, inspection is minimal except in certain areas of the country. The concept of performance-based wind engineering (PBWE), a relatively new paradigm, relies on the assumption that building performance under wind loads can be accurately modeled. However, the discrepancy between what is designed (and modeled) and what is built (the as-built) may make application of PBWE to light-frame wood buildings quite difficult. It can be concluded from this study that construction quality must be controlled for realistic application of PBWE to light-frame wood buildings.

  • By making use of the familiar concept of neighborhoods of analytic functions, we prove several inclusion relationships associated with the (n, ${\delta}$)-neighborhoods of certain subclasses of p-valent analytic functions of complex order with missing coefficients, which are introduced here by means of the Saitoh operator. Special cases of some of the results obtained here are shown to yield known results.

  • The purpose of this study was to provide basic information about the study of model development of sustainable housing area. So, this study identified the concept of sustainable development and condition after investigation Habitat Agenda II, and the 10 items of agenda were used to constitute the case study framework. This study found the development characteristics through the case study of 6 sustainable housing areas in the world(US, UK and Australia), and searched the missing point in the sustainable development concept. The major findings are summarized as follows: First, the attempt of environmental sustainability was restrictive such as minimal environment pollution and waste, water resource protection and conservation of nature ecosystem. Second, in social-culture sustainability, the effort of right to housing, solution of urban squatter and housing welfare eliminated. Third, in economic sustainability, the attempt of prevent natural disaster, technological and industrial disaster excluded.

  • This study aims to select eight books to see if "potential complement" is sufficiently acquired and properly used in Chinese conversation textbooks, explore the reasons and problems of learners' errors through analysis, and briefly suggest textbook compilation and teaching. Twelve criteria were established and analyzed, including the concept and format of "potential complement", layout order, location of objects, three types of forms, distinction from auxiliary verb "能" and distinction between "能+V+結果補語". Some of the results of the study are simply as follows. All eight textbooks focus only on "possibility," missing an important part of "the impact of objective conditions" that the term "potential complement" does not contain. This is certainly enough to cause confusion for learners. A poor understanding of the concept of "potential complement" results in identifying it with the possible auxiliary verb "能", and incorrect mixing because it does not know exactly what the difference is. Most of the textbooks compiled in China place a high importance on "potential complement". This means that Chinese people often use "potential complement" in real life. on the other hand relatively Korean textbooks do not deal with "potential complement" relatively importantly.

  • The purpose of this study was to provide basic information about the study of model development of sustainable housing area. This study identified the concept of sustainable development and the principles of the Habitat AgendaII. In the context, the 10 items of it were used to constitute the case study framework. This study found the planning characteristics through the case study of sustainable housing areas m Korea. The case for the study were 91 cases of Livable City Making of government and 43 cases of Urban Village Making of citizen group. And this study searched the missing point in the sustainable development concept of the practice cases. The research findings are as follows. First, the most practice cases had the aim of rehabilitation of the village functions. Second, in the cases of Livable City Making, residents practiced the rule as a participant for changing of their village. Third, in the cases of Urban Village Making, the scale were smaller than government's cases, but they tried the residents' health and welfare. Fourth, many cases applied the concept of sustainable development; environmental, social-cultural and economic sustainability, but some cases missed several principles of the Habitat Agenda.

This paper asks whether the Republic of Korea (ROK) Navy should Study on ROK Navy's Strategy Planning - Concerning to JOAC, ASB Concept of US Armed Forces - (한국 해군의 전략 수립 방향 연구 - 미군의 JOAC, ASB 개념 분석과 한국 해군에의 함의-)

  • The purpose of this thesis is to suggest how to plan ROK(Republic of Korea) Navy's strategy concerning to JOAC(Joint Operation Access Concept) and ASB(Air-Sea Battle) concept of US(United States) armed forces. Since 2006, US armed forces has been developing CONOPS(Concepts of Operations), JOAC & ASB. These concepts will not only affect security environment for Korea Peninsula and West Pacific Area, but also will be affected to ROK Navy's Strategy. Therefore, Korea Navy has to consider and review those concepts and should discuss the way to secure peace of Korea Peninsula. JOAC & ASB have been developed for securing operational access ability of US armed forces against enemy forces. A2/AD(Anti-Access, Area-Denial) is the strategy of possible enemy forces against US forces' approaching into the operation area and impede operations within area. US forces had to overcome enemy's A2/AD strategy in coming century to protect national interest and sustain global leadership. The main concept of JOAC & ASB is "Cross-domain Synergy", which means 'to eliminate duplicate and improve joint operability containing space and cyber operation area.' Korea Navy's acceptance of JOAC & ASB without any revising is not a rational choice. Without the amendment some problems can be occurred by the Korea navy's acceptance for the original version of JOAC & ASB. Those are "Missing differences of operation environment between Korea and US", "Impediment from neighbor nations, especially PRC (People's Republic of China)", and "Impediment inside from Korea armed forces". Therefore, Korea Navy has to evaluate and find out the way to solve for JOAC & ASB to apply for their strategy and minimise those possible problems above. This thesis is expected to be the solution.
