This study analyzes the impacts of undergraduate-work-experiences for beauty-major's graduates. 168 samples were selected from Graduates Occupational Mobility Survey data 2012 ~ 2017. As a result of a Multiple logistic regression analysis, a job experience, job period, and number of experienced job type mattered. In case of having non-major job experience while studying, the opportunities of finding a job of one who has no experience was higher than that of one had over a year work experience. While in case of having major job experience in the field of studying, one who has experience over 6 months and less than a year had higher chance in finding a job than that of one who had over a year work experience. I hope this promotes reviewing a systematic educational policy and helps to get a fundamental information on job-seeking behavior of beauty major graduate.

Most of the existing algorithms try to disseminate the multimedia contents of internet service provider(ISP), without taking into account the needs and characteristics of specific websites including e-learning systems with web-based .educational contents. Sometimes the client must select the best one among the replicated repositories. However, this is a less reliable approach because clients' selections are made without prior information on server load capacity. In this paper we propose an agent system inspired by the need of improving QoS of delivering web-based educational multimedia contents without incurring long access delays. This agent system consists of three components, Analyzer, Knowledge Base, and Automaton embedded the capacity algorithm. It analyzes and investigates traffic information collected from individual replicated server by learners' requests, and selects a server which is available and is expected to provide the fastest latency time and the lowest loaded capacity, and achieves high performance by dynamic replicating web resources among multiple repositories.

Our agricultural extension system with all its success and failures, rewards and punishment was introduced 50 years ago with particular reference from United States. Some of the established principles and policies of effective extension work were shaken off for immediate result. But the results were not praiseworthy. The purpose of this study is to throw some light on the question of systems and approaches on agricultural extension that can adequately meet the challenges of the future. Our extension system is `special government type` which administers a nation-wide network of extension and training services in close collaboration with that of the experiment station. This type, however, has innate weakness which inclined to be standardized, inflexible, and irrelevant to actual needs of farming communities and problems of farmers. In this regard, it is necessary to consider another approaches of agricultural extension: `Government Type`, `Agricultural University`, `Farmers Organization`. The characteristics features, advantages and disadvantages of these models have been discussed. Each model has been found wanting in one way or another to meet the needs and interest of the present Korean situation. In view of the agricultural situation, and considering the expected changes of farmers and technologies in the years ahead, the `modification (especially to the direction of provincial government) of preset system` was expected which would be operationally flexible and organizationally unified and decentralized. The modification of present system should include the following characteristics: 1) universal contact with client system, 2) local planning based on the needs of clients, 3) using multiple method of nonformal education, 4) fitting with both general and specialized farming systems, 5) accommodating variable clients, technologies and educational objects.

This paper proposes the ship-handling simulator framework using web technology to solve the complexity and non-scalability problems of a common simulator system. We analyze the essential functions of the existing simulator system, and selects web technologies to replace them. Based on this framework, we implemented core technologies for server and client system, and integrated a prototype of a ship-handling simulator system that can be accessed from a web browser. The prototype has verified that the simulation service can be used by multiple users at the same time without being restricted by time and place through the evaluation test, and it is hoped that it can be applied to various simulation fields in the future.

[purpose] This study was conducted to identify how a hospital's outsourcing workers' QWL influences Turnover Intention and to determine Dual Commitment cause any discrepancies in regards to the link between QWL and Turnover Intention. [Methodology/Approach] The study is based on 254 survey sheets answered by outsourcing employees working at general hospitals with more than 300 beds in Seoul and the methods of analysis used are as follows: reliability analysis, correlation analysis, multiple regression analysis, and hierarchical regressions analysis. [Findings] The study results First, analyzing how different types of QWL (individual, organizational, managemental) influence Turnover Intention, R2 turned out to be 30.7% and organizational factors and managemental factors show a statistically significant difference. In addition, organizational and managemental factors have negative effects on Turnover Intention while that of organization factors has a bigger influence. Second, verifying regulation effects of Dual Commitment in regards to the link between QWL and Turnover Intention, it is learned that Dual Commitment (hiring firm) has no regulation effects on the link. However, it does have a regulation effect on the link between QWL (managemental) and Turnover Intention. Moreover, after verifying regulation effects of Dual Commitment (client's firm), it is learned that it has regulation effect on the link between QWL (organizational and managemental) and Trunover Intention. [Practical Implications] In conclusion, lower Turnover Intention, it is necessary to impose tasks that suit the employees' competence and to encourage efficiency throughout clear communications and accurate directions.

This paper describes the development of 3-D web graphic library for dynamic web graphic design. The 3-D web graphic library developed in this per supports creation of 3-D objects like cube and sphere objects, elimination of hidden line and surface, and the shading of diffuse and specular reflections. It provides, in drawing, perspective projection of an object depth first sort of multiple objects, and wire frame and solid models. It also supports texture mapping function for realistic and dynamic web application in application software. Each created 3-D object gives functions for the scaling, translation, and rotation of itself. It can be used for the development of dynamic web application software and the advertisement of information for business and tourism as a 3-D web graphic library engine. It is written in 'Java' language and runs on web browsers with Java virtual machine without any dependancy of client computer system.

The update transactions to be executed in spatial databases usually have been known as interactive and long duration works. To improve the parallelism of concurrent updates, it needs multiple transactions concurrently update a large spatial object which has a spatial extensions larger than workspace of a client. However, under the existing locking protocols, it is not possible to concurrently update a large spatial object because of conflict of a write lock This paper proposes a partial locking scheme of enabling a transaction to set locks on parts of a big object. The partial locking scheme which is an exclusive locking scheme set by user, acquires locks for a part of the big object to restrict the unit of concurrency control to a partial object of a big object. The scheme gives benefits of improving the concurrency of un updating job for a large object because it makes the lock control granularity finer.

Sharing cross-site resources has been adopted by many recent websites in the forms of service-mashup and social network services. In this change, exploitation of the new vulnerabilities increases, which includes inserting malicious codes into the interaction points between clients and services instead of attacking the websites directly. In this paper, we present a system model to identify malicious script codes in the web contents by means of a remote verification while the web contents downloaded from multiple trusted origins are executed in a client's browser space. Our system classifies verification items according to the origin of request based on the information on the service code implementation and stores the verification results into three databases composed of white, gray, and black lists. Through the experimental evaluations, we have confirmed that our system provides clients with increased security by effectively detecting malicious scripts in the mashup web environment.

In this paper, we Introduce the Unreal Tournament (UT) game and the Gamebots system. The former it a well-known 3D first-person action game and the latter is an intelligent agent research testbed based on UT And then we explain the design and implementation of KGBot, which is an intelligent non-player character deploying effectively within the 3D virtual environment provided by UT and the Gamebots system. KGBot is a bot client within the Gamebots System. KGBot accomplishes its own task to find out and dominate several domination points pro-located on the complex surface map of 3D virtual environment KGBot adopts UM-PRS as its control engine, which is a general BDI agent architecture. KGBot contains a hierarchical knowledge base representing its complex behaviors in multiple layers. In this paper, we explain details of KGBot's Intelligent behaviors, tuck af locating the hidden domination points by exploring the unknown world effectively. constructing a path map by collecting the waypoints and paths distributed over the world, and finding an optimal path to certain destination based on this path graph. Finally we analyze the performance of KGBot exploring strategy and control engine through some experiments on different 3D maps.

This paper introduces an implementation of the diagnosis software for CC-NUMA systems. The CC-NUMA architecture is composed of two or more SMP nodes installed with the specialized hardware to provide cache-coherent operation and the high-speed interconnection network to connect each node, it enables both the high performance and the high scalability. While the CC-NUMA system provides the single system image in the operating system aspect, it should be considered the multiple systems by the diagnostic software. Thus it is difficult to diagnose and manage CC-NUMA system using commercial administration software due to characteristics of the complicated architecture. The remote diagnosis and management are also required with a view to reduce Total Cost of Ownership. In this paper, we design diagnostic software to manage CC-NUMA server system, and propose its mechanism in client-server manner to support remote administration. Additionally, we use the Java-based user interface to enlarge an administrator's accessibility.
