This study was carried out for the purpose of presenting basic data bases for conservation and management measures of Ecological and Scenery Conservation Area in Bongsan. The analysis results of the actual vegetation showed that rate of vegetation cover were composed of 72.3% of Robinia pseudo-acacia Forest, 10.7% of Sorbus alnifoila Forest, and Sorbus alnifoila was founded as a dominant woody plant species in the Core Zone of Bongsan Ecological and Scenery Conservation Area. To investigate the vegetation structure of Sorbus alnifolia Community in Bongsan Ecological and Scenery Conservation Area, twelve $100m^2$ sized plots were set up in Bongsan. According to the classification by TWINSPAN, the communities were divided into the three groups of Sorbus alnifolia Community, Pinus koraiensis Community and Robinia pseudo-acacia Community, To analyze annual diameter growth rate for major tree species, nine sample trees from research plots were measured. Expected ages of Sorbus alnifoila trees were 27~37years, Robinia pseudo-acacia trees were 17~26 years, Pinus koraiensis, Pinus rigida, Prunus sargentii, and Quercus mongolica trees were 27~38 years. As a result, annual diameter growth rates of Robinia pseudo-acacia and Pinus rigida tended to remarkably decreased, Sorbus alnifoila had the wood on inter-specific competition of the woody plant species. Importance values of Sorbus alnifoila in the three layers of Sorbus alnifoila communities were evenly high.

The present study was conducted to develop a Multi-dimensional Body Image Scale for Malaysian female adolescents. Data were collected among 328 female adolescents from a secondary school in Kuantan district, state of Pahang, Malaysia by using a self-administered questionnaire and anthropometric measurements. The self-administered questionnaire comprised multiple measures of body image, Eating Attitude Test (EAT-26; Gamer & Garfinkel, 1979) and Rosenberg Self-esteem Inventory (Rosenberg, 1965). The 152 items from selected multiple measures of body image were examined through factor analysis and for internal consistency. Correlations between Multi-dimensional Body Image Scale and body mass index (BMI), risk of eating disorders and self-esteem were assessed for construct validity. A seven factor model of a 62-item Multi-dimensional Body Image Scale for Malaysian female adolescents with construct validity and good internal consistency was developed. The scale encompasses 1) preoccupation with thinness and dieting behavior, 2) appearance and body satisfaction, 3) body importance, 4) muscle increasing behavior, 5) extreme dieting behavior, 6) appearance importance, and 7) perception of size and shape dimensions. Besides, a multidimensional body image composite score was proposed to screen negative body image risk in female adolescents. The result found body image was correlated with BMI, risk of eating disorders and self-esteem in female adolescents. In short, the present study supports a multi-dimensional concept for body image and provides a new insight into its multi-dimensionality in Malaysian female adolescents with preliminary validity and reliability of the scale. The Multi-dimensional Body Image Scale can be used to identify female adolescents who are potentially at risk of developing body image disturbance through future intervention programs.

This study performed to provide the basic information about the effects of the health management importance awareness on the occupational performance and basic fitness for the people with intellectual disabilities. 16 people with intellectual disabilities participated in muscle strengthening exercise. To assess health management importance awareness, the Canadian Occupational Performance Measure was used to identify the importance of the health management. According to the results of the importance, they were divided into two groups: Extreme and Neutral Importance Group in order to analyze the changes of the occupational performance and basic fitness. In-group analysis of the performance, satisfaction level, strength, and flexibility found that all measures improved in both groups following completion of the program. Between-group analysis following completion of the program indicated group differences in the performance and satisfaction level, but no group differences were found in the muscle strength and flexibility. Thus, this study showed the positive effects from the results of the program participation targeting the people with intellectual disabilities, and highlighted the importance of the awareness for them regarding the need for the health management (as evidenced by the improvement in occupational performance). It is expected that effective health management through participation in programs such as this will help maintain a healthy lifestyle and contribute to improve the quality of life.

In a fault tree analysis, an uncertainty importance measure is often used to assess how much uncertainty of the top event probability (Q) is attributable to the uncertainty of a basic event probability ($q_i$), and thus, to identify those basic events whose uncertainties need to be reduced to effectively reduce the uncertainty of Q. For evaluating the measures suggested by many authors which assess a percentage change in the variance V of Q with respect to unit percentage change in the variance $\upsilon_i$ of $q_i$, V and ${\partial}V/{\partial}{\upsilon}_i$ need to be estimated analytically or by Monte Carlo simulation. However, it is very complicated to analytically compute V and ${\partial}V/{\partial}{\upsilon}_i$ for large-sized fault trees, and difficult to estimate them in a robust manner by Monte Carlo simulation. In this paper, we propose a method for experimentally evaluating the measure using a Taguchi orthogonal array. The proposed method is very computationally efficient compared to the method based on Monte Carlo simulation, and provides a stable uncertainty importance of each basic event.

The purpose of this study is to analyze the correlation between importance and satisfaction of beauty contest using IPA(Importance-Performance Analysis) by deriving the quality factors of contest for revitalize beauty contest. For the study, a survey was conducted on participants with experience participating in beauty contest, and the collected data were analyzed using a response sample t-test and a PIA matrix. The results are as follows. First, there was a difference in importance and satisfaction as the average of importance was high. Second, in the first quadrant of the IPA matrix, contents related to contest assignment were mainly shown. This was analyzed as an effective factor that can improve the quality of the competition. Third, in the second quadrant, factors related to contest review were distributed. Accordingly, measures are required to increase the expertise and transparency of review. Fourth, in the third quadrant, the contents of the contest operation are mainly shown, and the satisfaction level is low, but supplementing it will have an improvement effect. Fifth, in the fourth quadrant, the satisfaction of the ability improvement item was high, which is analyzed that the contest experience affects the improvement of individual skills. Through this, it is significant to be used as basic data to establish a plan for revitalizing beauty contest.

The effective control of cost overrun is a crucial issue for construction companies to secure profitability. Especially in situations where cost pressures are significant due to factors such as rising raw material prices and increased financial costs due to high-interest rate policies, cost overruns resulting from project failures have a highly detrimental impact on the profitability of construction firms. The objective of this study is to analyze the current status of cost overrun control measures adopted by construction companies using the IPA technique and provide key characteristics and implications. The IPA analysis results showed that practitioners in general contractors exhibit a high level of interest and effort regarding cost overrun while the performance level is relatively low. Nevertheless, the measures considered important to control cost overruns generally show a high tendency for execution as well. Cost overrun control measures that show high importance but low execution are primarily related to collaboration and communication sectors. To effectively control cost overruns, enhancing collaboration and communication with construction supervisors/CM, headquarters, and regulatory authorities emerged as the most urgent need. Through this study, the current status and areas for improvement regarding cost overrun control measures in general contractors can be identified. This can be valuable for deriving directions and enhancements for future cost overrun control strategy development.

Many state agencies and companies collect personal data for the purpose of providing public services and marketing activities and use it for the benefit and results of the organization. In order to prevent the spread of COVID-19 recently, personal data is being collected to understand the movements of individuals. However, due to the lack of technical and administrative measures and internal controls on collected personal information, errors and leakage of personal data have become a major social issue, and the government is aware of the importance of personal data and is promoting the protection of personal information. However, theory-based training and document-based intrusion prevention training are not effective in improving the capabilities of the privacy officer. This study analyzes the processing steps and types of accidents of personal data managed by the organization and describes measures against personal data leakage and misuse in advance. In particular, using Capture the Flag (CTF) scenarios, an evaluation platform design is proposed to respond to personal data breaches. This design was proposed as a troubleshooting method to apply ISMS-P and ISO29151 indicators to reflect the factors and solutions to personal data operational defects and to make objective measurements.

Recently, as global-scale problems, such as global warming and energy depletion, have attracted attention, the importance of future environmental preservation has been emphasized worldwide, and various measures have been proposed and implemented. This study focuses on water hammer pumps that can effectively use the water hammer phenomenon and allow fluid transport without drive sources, such as electric motors. An understanding of operating conditions of water hammer pumps and an evaluation of their basic hydrodynamic characteristics are significant for determining whether they can be widely used as an energy-saving device in the future. However, conventional studies have not described the pump performance in terms of pump head and flow rate, common measures indicating the performance of pumps. As a first stage for the understanding of water hammer pump performance in comparison to the characteristics of typical turbo pumps, the previous study focused on understanding the basic hydrodynamic characteristics of water hammer pumps and experimentally examined how the hydrodynamic characteristics were affected by the inner diameters of the drive and lift pipes and the angle of the drive pipe. This paper suggests the effect of the air volume in the air chamber that affects the hydrodynamic characteristics and operating conditions of the water hammer pump.

This paper analyzes the interaction between monetary and macroprudential policies mainly in the context of the non-cooperation among policy authorities. Each policy authority's optimal response is to tighten its policy measures when other authorities' policy measures are loosened. This indicates that the two policies are substitutes for each other. This result still holds when an additional financial stability mandate is assigned to the central bank. The condition for the response functions to converge to a Nash equilibrium state is analyzed along with the speed of convergence, showing that they depend on the authorities' preferences and the number of mandates assigned to policy authorities. If the financial supervisory authority (FSA) assigns greater importance to the output gap or a stronger financial stability mandate is assigned to the central bank (CB), the probability of non-convergence increases and the speed of convergence declines even when the condition of convergence is satisfied. Meanwhile, if the CB considers output stability as an important task, the probability of convergence and the speed of converging to a state of equilibrium are high. Finally, when a single mandate or small number of mandates is/are assigned to each authority, stability is more quickly restored as compared to when many mandates are assigned.
