In the current age, as the importance of image is increased, brand images are strengthened, and various ways of expressing space are suggested considering the life styles of consumers. Recently, flagship stores are attempting various ways of expressing interior deigns and the flow of life culture, which can maximize the characteristics of image in a large, complex space. Centering on this trend, this study is conducted to explore an objective standard for the stylistic image characteristics reflecting the formative expression trend; to investigate various expression methods of images that are suggested by flagship stores; and to suggest the indicators of design. Based on this background, the formative trend is classified into the expression trends of minimalism and deconstructionism. An image evaluation test was conducted on the selected brand cases by applying the classification, and the following results are obtained from a comparative analysis. In this study, a stylistic analysis of expression methods is suggested from the stylistic image characteristics of each brand as well as from the reliability and validity of the expression trend. It can be concluded that such stylistic image characteristics are important factors in relation with fashion and architecture, and they can be used for differentiating design expression methods.

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.

The objective of this study was to investigate non-point sources (NPS) pollution and prioritize management areas affected by NPS pollution in the Saemangeum Watershed. AHP (Analytical Hierarchy Process) technique was selected to prioritize sub-watersheds for effectively managing NPS pollution in this study areas. Generation properties of NPS pollution, discharge properties of NPS pollution, and runoff properties of NPS pollution were selected and set for AHP. Weighted descriptors including indicators like numbers of livestock, land- and livestock-system loads, rainfall, and impervious area ratio were generalized from 0 to 1 and multiply each index based on screened 17 survey data. The results were visualized as maps which enable resource managers to identify sub-watersheds for effective improving water quality. The sub-watersheds located in Gongdeok-Myeon, Yongji-Myeon, Hwangsan-Myeon of Gimje-Si were selected for managing NPS pollution control areas. This result presented that these sub-watershed are more affected by the pollution from livestock-system than from land-system. The finding from this study can be used to screen sub-watersheds that need further assessment by managers and decision-makers within the study area.

This study aimed at setting up the grading indicator standards on development stages for phasing the continuous development process. To achieve the objective of this study, after referring to the proposed cases derived from the reference analysis, the development stages were classified. Also grading criteria of indicators according to development stages were established through the statistical analysis and expert group checking. Development stages of rural village were stepped into 4-stages through the reviews and analysis of reference literature ; preparation-entry-development-advanced stage. Reasonable achievement level of each development stage was established by considering the necessary development period and benchmarking reference target together. On the basis of these clear stepwise development phases, the grading criteria were proposed for determination of the incumbent development stages.

The main purpose of this study was to derive managerial priority for pollutants in drinking water using the Delphi technique and analytic hierarchy process (AHP) method. We collected fundamental existing items based on a literature review for water pollutants, and deduced a total of 36 sub-items from nine core sectors, as follows: organic matter; inorganic substances; pathogenic organisms; chemicals; heavy metals; radioactive substances; sediment deposits; heat; and oil, and then conducted the first round of an expert study to ensure that objective indicators properly evaluate major issues for management of for drinking water quality. In the following round, the necessity and importance assessments of adjusted items were implemented using a content validity ratio index. Finally, items modified by Delphi surveys were applied to AHP. We computed weighted values by pair-wise comparison of sub-items and each of five sectors modified by the second round. According to the results of AHP, the managerial priority for pollutants in drinking water was as follows; while heavy metal placed first in importance, pathogenic organisms came second, followed by inorganic substances, organic matter and chemical substances from the sector perspective.

Purpose: To examine the relationship between nurse staffing level and nurse perception of nursing performance. Method: The subjects of this study were 724 nurses from 70 medical or surgical wards in 23 hospitals from February to March 2006. A self-reporting questionnaire, which was developed by the researcher through a preceding study, was used. In data analysis, SAS program was utilized for descriptive statistics, t-test, ANOVA, and Tukey test. Results: The mean score of the nursing performance was 53.3. The mean of bed-to nurse ratio was 3.39:1. The study revealed a negative correlation between bed-to nurse ratio and the nurses' perception of nursing performance. There was a significant relationship between above 3.5:1 and below 2.5:1(F=4.59, p=0.010). Conclusion: We found that the higher the nurse staffing, the better the nursing performance. It is recommended that future research measures nurses' performance and nursing organizational performance using objective measurement tools including clinical indicators.

IT 투자는 기업의 일반적인 투자와는 달리 직접적인 효과를 계량화하기 어려운 부분이 있기 때문에 재무적 측정지표만으로 IT 투자의 성과를 제대로 평가 할 수 없다. 따라서 본 논문은 IT 투자와 그 투자에서 얻어지는 비재무적 효과를 포함한 효과를 화폐가치로 변환 후 투자수익률을 분석하는 방법론을 제시한다. 이 방법론은 IT 소유비용을 체계적으로 분석해서 가시적 인 비용뿐만 아니라 숨겨진 비용도 파악한다. 또한 IT투자로 인한 재무적인 효과와 비재무적인 효과를 화폐가치화 하여 IT ROI를 산출한다. 본 논문은 정보시스템이 기업의 활동에 기여하는 효과를 객관적인 타당성을 확보하여 IT투자 의사결정을 도와주고, IT 투자우선순위를 보다 합리적으로 결정할 수 있어 효율적인 IT투자가 이루어질 수 있는 체계를 제시한다.

To determine what is the change of pre and postoperative voice and image analysis parameters and correlations between them, videostroboscopy was analyzed in each 18 patients with unilateral vocal cord paralyses or vocal polyps before and after the surgery from November, 1996 to April, 1999. The correlation between acoustic and aerodynamic parameters was investigated. The software-Videolink and $\pi$-View(Mediface Co, Seoul, Korea)-was used in a quantitative analysis. In unilateral vocal cord paralysis, the glottic angle is well correlated with maximum phonation time, jitter and shimmer preoperatively. The postoperative glottic angle is also correlated with preoperative maximum phonation time. In patients with the vocal polyp, the chink is postoperatively decreased, but the size of the chink and the polyp is not correlated with pre and postoperative voice analysis parameters. These findings reveal that glottic an and vocal fold angle are good indicators of e postoperative glottic configuration in unilateral vocal cord paralysis. Vocal fold ratio is also a useful indicator that represents the length of vocal folds. We consider that the computerized analysis through videostroboscopy is one of objective diagnostic methods in many voice disorders if we can measure a distance between the telelaryngoscope and vocal folds.

Using a level set method and topological derivatives, a topological shape optimization method that is independent of an initial design is developed for linearly elastic structures. In the level set method, the initial domain is kept fixed and its boundary is represented by an implicit moving boundary embedded in the level set function, which facilitates to handle complicated topological shape changes. The 'Hamilton-Jacobi (H-J)' equation and computationally robust numerical technique of 'up-wind scheme' lead the initial implicit boundary to an optimal one according to the normal velocity field while minimizing the objective function of compliance and satisfying the constraint of allowable volume. Based on the asymptotic regularization concept, the topological derivative is considered as the limit of shape derivative as the radius of hole approaches to zero. The required velocity field to update the H -J equation is determined from the descent direction of Lagrangian derived from optimality conditions. It turns out that the initial holes is not required to get the optimal result since the developed method can create holes whenever and wherever necessary using indicators obtained from the topological derivatives. It is demonstrated that the proper choice of control parameters for nucleation is crucial for efficient optimization process.
