In these days, information communication systems are based on both open distributed computing technologies and object-oriented techniques like inheritance, encapsulation and object reuse to support various system configuration and application. As information systems are interconnected through unsecure networks, the need for the secure information exchange is more critical than before. In this paper, we have designed and implemented a transparent CORBA-basce Security infrastructure with authentication, security context association, access control and security information management to support a secure applications in distributed object environment. SESAME Ver. 4 was adopted as an external security service to manage user privilege attributes and to distribute keys for data encryption, decryption and integrity. Using filter and transformer with an interface to Object Request Broker, it provides a transparent security service to applications. The filter objects are special classes that allow additional parameters to be inserted into messages before they are sent and removed just after they are received. The transformer objects are special classes that allow direct access to the byte stream of every messages for encryption and decryption before it is sent and just after it is received. This study is to implement the access control interceptor(ACI) and the secure invocation interceptor(SII) of secure ORB defined in CORBA using filter and transformer.
Background: This study aimed to analyze the impact of community health care resources on the place of death of older adults with dementia compared to those with cancer in South Korea, using public administrative big data. Methods: Based on a literature review, we selected person- and community-level variables that can affect older people's decisions about where to die. Data on place-of-death and person-level attributes were obtained from the 2013 death certification micro data from Statistics Korea. Data on the population and economic and health care resources in the community where the older deceased resided were obtained from various open public administrative big data including databases on the local tax and resident population statistics, health care resources and infrastructure statistics, and long-term care (LTC) insurance statistics. Community-level data were linked to the death certificate micro data through the town (si-gun-gu) code of the residence of the deceased. Multi-level logistic regression models were used to simultaneously estimate the impacts of community as well as individual-level factors on the place of death. Results: In both the dementia (76.1%) and cancer (87.1%) decedent groups, most older people died in the hospital. Among the older deceased with dementia, hospital death was less likely to occur when the older person resided in a community with a higher supply of LTC facility beds, but hospital death was more likely to occur in communities with a higher supply of LTC hospital beds. Similarly, among the cancer group, the likelihood of a hospital death was significantly lower in communities with a higher supply of LTC facility beds, but was higher in communities with a higher supply of acute care hospital beds. As for individual-level factors, being female and having no spouse were associated with the likelihood of hospital death among older people with dementia. Conclusion: More than three in four older people with dementia die in the hospital, while home is reported to be the place of death preferred by Koreans. To decrease this gap, an increase in the supply of end-of-life (EOL) care at home and in community-based service settings is necessary. EOL care should also be incorporated as an essential part of LTC. Changes in the perception of EOL care by older people and their families are also critical in their decisions about the place of death, and should be supported by public education and other related non-medical, social approaches.

Increasing transportation dependence on the metro system has lead to the convenience of passengers becoming as important as the transportation capacity. In this study, a pedestrian simulator has been developed that can quantitatively assess the pedestrian environment in terms of attributes such as speed and distance. The simulator consists of modules designed for 3D indoor map authoring and algorithmic pedestrian modeling. Module functions for 3D indoor map authoring include 3D spatial modeling, network generation, and evaluation of obtained results. The pedestrian modeling algorithm executes functions such as conducting a path search, allocation of users, and evaluation of level of service (LOS). The primary objective behind developing the said functions is to apply and analyze various scenarios repeatedly, such as before and after the improvement of the pedestrian environment, and to integrate the spatial information database with the dynamic information database. Furthermore, to demonstrate the practical applicability of the proposed simulator in the future, a test-bed was constructed for a currently operational metro station and the quantitative index of the proposed improvement effect was calculated by analyzing the walking speed of pedestrians before and after the improvement of the passage. The possibility of database extension for further analysis has also been discussed in this study.
This study aims to analyze importance and performance factors on the quality of wellbeing fusion menu of fusion restaurants to provide helpful information for building up a detailed marketing strategy and present considerations for sales increase and more efficient business results. Importance on menu quality scored a higher level than performance on the whole in fusion restaurants. Notably, in regard to attributes of menu quality, it was found that respondents put higher stress on 'taste of food', 'sanitary of food', 'cleanliness of vessels', 'quality of menu' and 'freshness of food' than anything else. Wellbeing fusion menu which has an high intake frequency rate includes 'green vegetable noodles with black bean sauce', 'sweet pumpkin salad', 'salmon salad', and 'shrimp vegetable gratin' in that order. On the other hand, the intake frequencies of 'ovened green perilla gratin', 'pomegranate dressing tofu', 'bacon roll with glutinous rice powder', and 'pomegranate dressing bacon' were rated very low. In terms of the IPA analysis on wellbeing fusion menu quality, it was important to continuously maintain 'taste of food', 'sanitary of food', 'cleanliness of vessels', 'freshness of food', 'quality of menu', 'diet menu(low fat, low calories)', 'vegetable menu', 'nutrition of food', 'variety of menu' etc. Such items as 'price', 'distinction with existing food', and 'environment-friendly organic agriculture food material' are in need of intensive care and operation.

The effects of addition of citrus peel powders (C 0, 0.5, 1 & 2%), dried Lentinus edodes powders (L 0, 0.5, 1 & 2%), and their combination (C-L) on the chemical, sensory and textural properties of pork sausages were studied. Addition of 0.5, 1 or 2% C, L, and C-L all significantly decreased moisture content, pH, and color a-values of sausage samples, whereas ash content and color b-value were increased (p<0.05). C, L, and C-L did not affect protein, fat, carbohydrates contents or texture characteristics. Sensory evaluation was performed by multivariate data analysis, namely principal component analysis (PCA). Eighty-two percent total variation was observed in the main structured information among the test groups: the first (PC1) and second (PC2) components of variation were 59 and 23%, respectively. Eight parameters (sweet flavor, pork aroma, bitterness, rancidity, salty flavor, color, sour flavor and citrus aroma) were utilized to describe the main sensory characteristic of the sausages. Addition of 0.5, 1 & 2% citrus peel was obviously correlated with PC1 (salty flavor, sour flavor and citrus aroma, pork aroma, and sweet flavor and rancidity), whereas addition of 0.5 & 1% Lentinus edodes was related with PC2 (aroma and rancidity).
The purpose of this research was to exam the recognition and use for traditional Korean liquors and to consider the problems of traditional liquor businesses and the plans for its popularization. This study was conducted with 411 adults of 20 years old and above, all of whom lived in the Daegu and Gyeongbuk Provinces. According to the survey, females were higher than males(49.6%) by 50.4%, and ages 20 was the highest. With regards to what kind of liquor they enjoyed, the consumers enjoyed soju the most, followed by beer and traditional Korean liquors. The favorite liquor of the men was soju, followed by beer and traditional Korean liquor, and the women mostly liked beer, followed by soju and wine. An important-performance analysis (IPA) was performed for 17 attributes of traditional Korean liquor and identified the targets for product management strategies, including 'Variety', 'Functionality', 'Extended Recognition' and 'Healing hangovers'. The recognition of traditional Korean liquor was high in the order of takju, Fruit wine, Chongju, Yakju, Distilled soju, and Distilled liquor. As a result, the developing solid concepts of marketing strategy are required and may be achieved by understanding the consumer preferences and demands of traditional Korean liquors.

This paper presents a study on the development of a web-based system for the road occupation permit information management. For the development of this system, the survey of information system related to a road occupation permit, an analysis of road occupation business process, the definition of the road occupation permit data, the development of the system, and the application of the system to the work-related to road occupation permit were conducted consecutively. In an analysis of the road occupation business process, the statutes, such as the road act were investigated, work examples of the road management agent were reviewed, and a survey targeting staff and citizens was carried out. The information classification code to represent the attributes of the data was developed to manage the information in each road occupation permit process, and the metadata was defined considering the hierarchy relationship of the information. The road occupation and access system was developed based on the information classification code and metadata to reflect the user requirements. The System was applied to the Regional Construction and Management Administration and Branch Office belonging to the Ministry of Land, Infrastructure and Transport Affairs. By replacing the business process based on paper documents to the business process based on the information system, it is expected that the service of the civil petition be upgraded and the business process of the road occupation permit be reformed.

This qualitative research examined the experiences and patterns of military life of service maladaptive soldiers. The research site was the place where the soldiers of the A-adaptive soldiers' healing program were conducted, and the study period was conducted from September 2016 to December 2017. Maladaptive soldiers' military life experience pattern was analyzed, and their experience consisted of three domains (early domain after joining the army, middle domain after joining the army, and last domain where they failed to adapt themselves), five cultural themes, 12 categories, and 29 attributes. The cultural themes of maladaptive soldiers in their military life experiences were as follows: facing unfamiliar military culture, hardship, being left alone in a group, pain becoming unbearable, and the last choice of leaving a painful military life. Maladaptive soldiers attempted suicide after they failed to overcome the psychological pain, but they needed help during their early period of adaptation. Moreover, during their middle period of adaptation, they needed guidance for their immature coping strategies, and ultimately they had misperceptions about their death together with a pessimistic view about their life. These results are expected to be used as basic data for the development of mental nursing arbitration programs and suicide prevention projects to help service maladaptive soldiers.

The consumer awareness concerning coffee beverages has increased in Korea. The objective of this study was to optimize the roasting conditions of coffee bean for consumer's attribute. The optimal roasting conditions for Colombian coffee beans were analyzed by using a central composite design with a quadratic polynomial model by response surface methodology (RSM). The experimental conditions for coffee bean roasting were $194.82^{\circ}C{\sim}250.00^{\circ}C$ and 7.93~22.07 minutes. The responses of sensory attributes. physicochemical and physical properties were analyzed with RSM. The width. length and height of green beans increased when the beans were roasted. The higher degree of roasting gave the higher pH and solid contents but the lower total acidity and total phenolic compounds. In sensory tests, the roasting temperature and time had a significant effect on the flavor score. The optimum roasting condition of Colombian coffee bean predicted for maximizing the length, width, solid contents, total phenolic compounds and flavor score were 20 minutes at $225^{\circ}C$ by RSM.
