Purpose: This study was performed to identify the effect of admission type on college adaptation and academic achievement in one nursing school in order to refine the entrance selection system. Methods: Subjects were 405 nursing students (female : male = 385 : 20, first grade = 155, second grade = 138, third grade = 112). They were given the Student Adaptation to College Questionnaire (SACQ) purchased from Western Psychological Service. SACQ is composed of 67 questions and subdivided into 4 subcategories: academic adjustment, social adjustment, personal-emotional adjustment, and attachment. Student college adaptation scores and academic achievements were analyzed with reference to the entrance selection system (rolling admission vs. regular admission) by SPSS 22.0. The rolling admission system recruited students based on high school records only while the regular admission system was based on both high school records and the College Scholastic Ability Test (CSAT). Results: Total College adaptation score, personal-emotional adjustment score, and academic achievement were higher in regular-admission students than in those admitted through rolling admission. Academic achievement for first-grade students was higher in regular-admission students than for those admitted through rolling admission, But the difference in academic achievement became null as students were promoted to the second and third grades. Conclusion: Students recruited using both high school records and the CSAT showed better college adaptation and higher academic achievement.

For the competitive business environment under purchase dependence, this paper proposes a new approximate calculation of order fill rate which is a probability of satisfying a customer order immediately using the existing inventory. Purchase dependence is different to demand dependence. Purchase dependence treats the purchase behavior of customers, while demand dependence considers demand correlation between items, between regions, or over time. Purchase dependence can be observed in such areas as marketing, manufacturing systems, and distribution systems. Traditional computational methods have a difficulty of the curse of dimensionality for the large cases, when deriving the stationary joint distribution which is utilized to calculate the order fill rate. In order to escape the curse of dimensionality and protect the solution from diverging for the large cases, we develop a greedy iterative search algorithm based on the Gauss-Seidel method. We show that the greedy iterative search algorithm is a dependable algorithm to derive the stationary joint distribution of on-hand inventories in the retailer system by conducting a comparison analysis of a greedy iterative search algorithm with the simulation. In addition, we present some managerial insights such as : (1) The upper bound of order fill rate can be calculated by the one-item pure system, while the lower bound can be provided by the pure system that consists of all items; (2) As the degree of purchase dependence declines while other conditions remain same, it is observed that the difference between the lower and upper bounds reduces, the order fill rate increases, and the order fill rate gets closer to the upper bound.

Although the construction industry has been rapidly increased at its size and technologies as a locomotive of the economy development in Korea, most construction companies have not paid their attention on the construction risks seriously. However, they have been experienced a lot of business deterioration and project instability during the IMF crisis and WTO entry, and trying to figure out a way to manage the construction intrinsic risks systematically. Some top ranked construction companies have already developed and been implementing a risk management system for the oversea construction projects applying for the marketing and bidding stage, but not for the domestic construction projects during construction phase yet. This paper proposes a construction risk management system model for the site personnel to understand and manipulate very easily in the construction project.

In this paper, we propose an accident-prevention smart monitoring system for Haenyeo(Woman diver) using Zigbee module and GPS sensor. This system can collect such information as the diving location, the body temperature, the depth of diving, and the diving time of a Woman diver working under the water and then respond immediately to an accident occurring. The research developed a smart Teawak and smart swimming goggles which can measure the state of a Woman diver and her diving activities. Smart Teawak, the buoy tool while a Woman diver is collecting seafoods under water, is able to receive GPS and transmit the data from smart swimming goggles and Zigbee Module to IHSS(IoT based Haenyeo Safety service Software) server. In addition, IHSS, a responsive web, provides the diving location and the state of a Woman diver on the smart phone. As a result, the system will be useful in the aspects of Woman diver' health care and the safety, furthermore, which will significantly contribute to global marketing of Woman diver with its being designated as a UNESCO intangible cultural asset.

TerraSAR-X, launched in June 2007, and TanDEM-X, June 2010, are remote-sensing satellites with 1M resolution that are capable of observing the ground even during the nighttime and poor weather conditions. The two satellites had been developed under a public-private partnership between the German Aerospace Centre and Airbus in the interest of the commercial marketing for German satellite data. However, the data of high-grade earth remote-sensing system, such as those of the satellites, has been produced by a military satellite and thus used under limited circumstances in Germany. Therefore, a legislation to commercialize the German satellite data and to protect its national security is needed. For this, SatDSiG was enacted in December 2007. Thus this article will contain the main contents of SatDSiG and its implication for Korea, which stared to export data of Kompsat 3, 3A and 5 in 2018.

While many users searched for insurance information online, there were not many cases of contents recommendation researches on insurance companies' websites. Therefore, this study proposed a page recommendation system with high possibility of preference to users by utilizing page visit history of insurance companies' websites. Data was collected by using client-side storage that occurs when using a web browser. Collaborative filtering was applied to research as a recommendation technique. As a result of experiment, we showed good performance in item-based collaborative (IBCF) based on Jaccard index using binary data which means visit or not. In the future, it will be possible to implement a content recommendation system that matches the marketing strategy when used in a company by studying recommendation technology that weights items.
