The aim of this study is to examine and compare Koreans and Japanese creativities in advertising. It was to analyze empirically their creativities appreciated in 200 TV commercials broadcasted between 1992 and 1998. The content analysis, was a useful process, provided very important clues for comparative analysis. Many difference were found in the examined TV commercials in Korea and Japan. It showed major difference in ways in which the level of noise, the using of cuts, social space, camera work, etc. except preference of jingle, colors, elements of tradition. The most distinctive difference is that the Japanese TV commercials deal with atmosphere than the Korean commercials. This result may help to explain a common social phenomenon of not losing the original culture in each society, as a result of "international acculturation" and the subsequent "indigenization by adaptive change"

위협 헌팅은 기존 보안 솔루션의 한계를 극복하기 위한 방어 기법이며, 최근 위협 헌팅에 대한 관심이 높아지고 있다. 위협 헌팅은 시스템 내부에 존재하는 위협을 식별 및 제거하는 기법으로 인식되고 있지만 그 정의가 명확하지 않기 때문에 모의 해킹, 침입 탐지, 침해사고 분석 등 다른 용어들과 혼용이 많이 발생하고 있다. 따라서 본 논문에서는 보고서 및 논문에서 발췌한 위협 헌팅의 정의를 비교 분석하여 그 의미를 명확히 하고 방어기법을 비교분석한다.

The purpose of this study is to analyze cognition of middle school students on an educational institute of life. For this purpose, the three times of in-depth interviews which were performed the subjects, 6 middle boy＇s school student. The data passed through process of three dimension, abstraction of idea, categorization, interpretation. In this process, were discovered four category of educational institute of life. It was pilgimage, activity, system, and compare with school. The major results of this study were follows: first, an educational institute of life is natural of life to student and they accept the life themselves not coercion gradully. second, study of educational institute is repetitional and many and only for school test. third, system of educational institute is concenturated for study, in this point, students distinguish school with educational institute. fourth, in compare with school, educational institute is more comfortable than school. Also, educational institute take care of student more than school.

We study on intuitive verification and rigor proof which are in geometry of Korean and Russian $7\~8$ grade's mathematics textbooks. We compare contents of mathematics textbooks of Korea and Russia laying stress on geometry. We extract 4 proposition explained in Korean mathematics textbooks by intuitive verification, analyze these verification method, and compare these with rigor proof in Russian mathematics textbooks.

The online advertising industry's business model undertakes the change from CPM (cost-per-mille)-based to CPC (cost-per-click)-based. However, due to the problem of 'Click Fraud', CPA (cost-per-action) has been regarded as a new step. For CPA, publishers need to get information after a user clicks an advertisement. Therefore, in CPA, the key is to get Conversion Action Data (CAD). This paper introduces two existing mechanisms for getting CAD, compare their characteristics, and analyze their limitations. Then the two new mechanisms are introduced and their requirements and feasibility are analyzed. Lastly, we compare the existing two and the new two mechanisms, and point out each mechanism's business possibility, value and Application Area. This paper will help publishers choose the most appropriate mechanism on the basis of their situation.

Geothermal heat exchanger(GHEX) is a major component of Geothermal heat pump system(GSHPs). In Common, We use the vertical type GHEX in Korea. But vertical type GHEX needs a high cost for installation, because of drilling the hole which has 200m depth at max. So, We suggest the use of horizontal type GHEX. When we construct buildins, We excavate the ground and we can install the horizontal type GHEX at the excavated underground. It's very cheap and convenient method compare to vertical type GHEX installation. This study is peformed to estimate the peformance of horizontal type GHEX and to analyze effects of heat exchanger types and undergroundwater. As the result, slinky type GHEX has a 66% efficiency compare to vertical type GHEX and mat type has a 201% efficiency at the undergroundwater zone.

After detecting the edge which is applying the morphological operators to the hybrid FCNN, we could analyze and compare. The hybrid FCNN is completely removed to the noise in the image, and worked in order to obtain the result image which is closest to the original image. Also, the morphological operator is applied to the image as the method in order to detect more good the edge than the conventional edge. FCNN which is the pipeline type is completely suitable to detecting the image processing as well as the hardware size. In this paper. we would make the structure elements of the morphological operator the variable template and the static template, and compare with the edge enhancement of two images. After being the result which is applying the variable template morphological operator and the static template morphological operator to the image, we could know that the edge images applying the variable template is superior in a edge enhancement side.

There is an extensive literature on retrial queueing models. While a majority of the literature on retrial queueing models focuses on the retrial times to be exponentially distributed (so as to keep the state space to be of a reasonable size), a few papers deal with nonexponential retrial times but with some additional restrictions such as constant retrial rate, only the customer at the head of the retrial queue will attempt to capture a free server, 2-state phase type distribution, and finite retrial orbit. Generally, the retrial queueing models are analyzed as level-dependent queues and hence one has to use some type of a truncation method in performing the analysis of the model. In this paper we study a retrial queueing model with threshold-type policy for orbiting customers in the context of nonexponential retrial times. Using matrix-analytic methods we analyze the model and compare with the classical retrial queueing model through a few illustrative numerical examples. We also compare numerically our threshold retrial queueing model with a previously published retrial queueing model that uses a truncation method.
