This study was designed to identify the relationship between health perception and health behavior in nursing students and provide basic data for structuring the strategies of health promotion. The targets in this study were the 191 nursing students in nursing department of one national university in Chonju city. The data were collected during the period from 10 to 25 in Nov. 1995 by means of a structured questionnaire. Health perception was measured by the health perception questionnaire developed by Ware and translated by You. Health behavior was measured by health promotion questionnaire developed by Cho. The data were analyzed by descriptive statistics, t-test, ANOVA and Pearson correlation using the $SPSS-PC^+$ program. The results of this study were as follows; 1. The mean health perception score of the subjects was 3.21; the level of health perception was relatively high. 2. The mean health behavior score of the subjects was 3.61; the level of health behavior was relatively high. 3. When health perception and health behavior was analyzed by Pearson correlation., it was found that the higher the degree of health perception, the better the reported health behavior(r=.1463, p=.022). 4. General characteristics related to health perception were attitude and school life(p<0.05). General characteristics related to health behavior were degree, religion, attitude and school life(p<0.05).

Anomaly detection of Machine Learning such as PCA anomaly detection and CNN image classification has been focused on cross-sectional data. In this paper, two approaches has been suggested to apply ML techniques for identifying the failure time of big time series data. PCA anomaly detection to identify time rows as normal or abnormal was suggested by converting subjects identification problem to time domain. CNN image classification was suggested to identify the failure time by re-structuring of time series data, which computed the correlation matrix of one minute data and converted to tiff image format. Also, LASSO, one of feature selection methods, was applied to select the most affecting variables which could identify the failure status. For the empirical study, time series data was collected in seconds from a power generator of 214 components for 25 minutes including 20 minutes before the failure time. The failure time was predicted and detected 9 minutes 17 seconds before the failure time by PCA anomaly detection, but was not detected by the combination of LASSO and PCA because the target variable was binary variable which was assigned on the base of the failure time. CNN image classification with the train data of 10 normal status image and 5 failure status images detected just one minute before.

The hot embossing process has been mentioned as one of major nanoreplication techniques. This is due to its simple process, low cost, high replication fidelity and relatively high throughput. As the initial step of quantitating the embossing process , simple parametric study about embossing time have been carried out using high-resolution masters which patterned by the DRIE process and laser machining. Under the various embossing time, the viscous flow of thin PMMA films into microcavities during compression force has been investigated. Also, a study about simulating the viscous flow during embossing process has planned and continuum scale FDM analysis was applied on this simulation. With currently available test data and condition, simple FDM analysis using FLOW3D was made attempt to match simulation and experiment.

Today, It is difficult to search the various and numerous information efficiently. For this reason, Semantic Web emerged to provide searching services more easily through the structuring of a variety of unstructured format data and the definition of meaningful relationships between information. Especially, definition of relationship and meaning among resources is significant to share and infer related information. Ontology modeling plays just that role. Weapon parts development information is unstructured and dispersed all over. There are many difficulties in finding desired information, leading to getting improper outcomes. In this paper, we present an intuitive ontology model with weapon parts development information including the multi-dimensional information analysis and expansion of the relevant information. This study build up a ontology model through creating class and hierarchy about parts information and defining the properties of classes with Ontology Development 101[1] procedures using Protégé tools. The ontology model provides users with a platform on which search of needed information can be easy and efficient.

An organizational performance measurement practice is a function of performance measurement system and performance management system they are currently employing, and its quality is determined by evaluating the followings in a comprehensive manner: first, if they are measuring right things; second, if they are measuring in a right way; third, if they are actively facilitating a process of data collection, structuring, analysis, interpretation, and dissemination; and fourth, if they are using performance measurement results for the primary purposes of performance measurement. This study proposes a diagnostic framework for evaluating the performance measurement practices of public broadcasting which include the qualities of performance measurement and performance management, and develop a structured questionnaire for that purpose. The framework proposed in this study does not serve only as a useful tool for public broadcasting to revise their respective performance measures and performance measurement systems, but it also make their respective performance measurement practices a strategic management tool as well as an operational management one.

Purpose: The Emission Trading Scheme (ETS), which enables structuring emission credits as a financial product, is taking a crucial position of global collaboration against climate change. Previous studies that have covered ETS subjects from the macro perspective contribute to facilitating legal enactment of this scheme. However, they have rarely addressed challenges aligned with issues arising from labor burdens for ETS works from the business perspective. Research Design, data and methodology: This study presents conceptual models that are expected to help design an electronic system. The study model contains four modules: emission allocation, data interface, reduction technology sharing, and emission trading. Two validation approaches, the Analytic Hierarchy Process (AHP) and regression analysis, are applied in confirming the feasibility of the proposed model. Results: This study suggests an IT system methodology to help improvement of the current K-ETS mechanism. In particular, this study addresses effectiveness for real businesses and the adaptability of this mechanism to other nations. Conclusions: The proposed IT platform diagram can contribute to successful operation of ETS by providing multiple benefits to participating companies through in-house allocation mechanisms, the soft-landing of ETS adoption to participating companies through reduction of technology-sharing, group purchases, and transaction costs through the trading system.

The purpose of this study was to investigate the wearing condition according to different basic slacks'patterns and to provide fundamental data on structuring slacks' pattern using the multi-dimensional measuring method. 3 different kinds of basic slacks' patterns (A, B, C) were used and cross-sectional measurements of 6 parts were analysed. The results were as follows; 1) It revealed that the girth of waist, hip and thigh effected the degree of ease amounts. 2) Moira pattern shape fully supported that the considerable body parts affected the change of ease amounts. 3) Basic pattern A was usually expected to be suitable for standard-sized or unmarried women who had not experienced body-type change. 4) Basic pattern B and C were suitable for large-sized or married women whose body·type had changed. Therefore the crotch length and depth, gredient of center back line has to be set up accurately.
