This paper presents a procedure for determining the design rainfall depth and the design rainfall intensity at Incheon city area in Korea. In this study the eight probability distributions are considered to estimate the probable rainfall depths for 11 different durations. The Kolmogorov - Smirnov test and the Chi-square test are adopted to test each distribution. The probable rainfall intensity formulas are then determined by i) the least squares (LS) method, ii) the least median squares (LMS) method, iii) the reweighted least squares method based on the LMS (RLS), and iv) the constrained regression (CR) model. The Talbot, the Sherman, the Japanese, and the Unified type are considered to determine the best type for the Incheon station. The root mean squared (RMS) errors are computed to test the formulas derived by four methods. It is found that the Unified type is the most reliable and that all methods presented herein are acceptable for determining the coefficients of rainfall intensity formulas from an engineering point of view.

The sign-language can be used as an auxiliary communication means between avatars of different languages in cyberspace. At that time, an intelligent communication method can also be utilized to achieve real-time communication, where intelligently coded data (joint angles for arm gestures and action units for facial emotions) are transmitted instead of real pictures. In this paper, a method of generating the facial gesture CG animation on different avatar models is provided. At first, to edit emotional expressions efficiently, a comic-style facial model having only eyebrows, eyes, nose, and mouth is employed. Then generation of facial emotion animation with the parameters is also investigated. Experimental results show a possibility that the method could be used for the intelligent avatar communications between Korean and Japanese.

This study examined the positive impact of workplace harassment on the employees' counterproductive work behavior at deluxe hotel in Seoul and Tokyo. The study verified a differentiated influence based on the nationality of the employees. The hypothesized relationships in the model were tested simultaneously by using structural equation modelling. First, isolation/exclusion (${\beta}=.403$), disrespectful behavior (${\beta}=.312$), physical aggression (${\beta}=.245$), and verbal aggression (${\beta}=.133$) had a positive impact on counterproductive work behavior. However, threats/bribes (${\beta}=.091$) did not show a significant impact. Second, no significant moderating effect based on employees' nationality (Korean versus Japanese) was observed in the relationship between the five workplace harassment factors and CWB. This study will investigate workplace harassment perceived by deluxe hotel employees in Korea and Japan, and the obtained data can also be used to help identify realistic plans to reduce workplace harassment between bosses and subordinates at an organizational level.

Between 2010 and 2012, former Bank of Japan Governor Shirakawa argued, in series of speeches, that Japan's economic performance, when compared to that of other G7 nations, was stronger after 1990 than appreciated by the critics. In May 2012, Nobel prize-winning economist and Princeton University professor Paul Krugman echoed a similar sentiment in a Financial Times interview. This analysis expands on these assertions and asks to what extent they are supported by cross-section data for the G7. As reviewed below, to date, no idiosyncratic explanation has arisen to explain the Japanese slowdown-perhaps this is the correct explanation: the slowdown in Japan, once adjusted for demographics, is less severe than in other G7 countries and, as recently noted by Eichengreen, Park, and Shin (2015), TFP growth in a number of other nations followed similar patterns. Focused on labor productivity, far from a laggard, Japan's performance ranks near the best in the G7.

This paper performed a basic study for the development of so called a Korean style community garden, a Kleingarten in Japan, according to the increase of demand for green tourism For this, theoretical research and interviews with site surveys for Kleingarten in Japan were carried out and some strategic conclusions were drawn. The results show that, from the perspective of hardware, facilities and size should be setup according to the condition in Korea and long-tenn demands for green tourism Adequate size of lodging facility, a cottage, should accompany the garden. More attention should be paid for the management of Kleingarten. In addition, from the perspective of software, Administration should make an effort to obtain the understanding and cooperation from the local residents. It turns out that a Kleingarten takes an important role when urban residents move into rural areas or carry out a multi-habitation. Barrier-free design for cottages is also needed.

Real-time rainfall monitoring is of great practical importance over the highly populated Indochina area, which is prone to natural disasters, in particular in association with rainfall. With the goal of d etermining near real-time half-hourlyrain estimates from satellite, the three-layer, artificial neural networks (ANN) approach was used to train the brightness temperatures at 6.7, 11, and $12-{\mu}m$ channels of the Japanese geostationary satellite MTSAT against passive microwavebased rain rates from Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and TRMM Precipitation Radar (PR) data for the June-September 2005 period. The developed model was applied to the MTSAT data for the June-September 2006 period. The results demonstrate that the developed algorithm is comparable to the PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks) results and can be used for flood monitoring across the Indochina area on a half-hourly time scale.

Movement from aging society to aged society and to ultra aged society is a fact that we have to accept as reality. It also means that we are given a common assignment of supporting the aged. Therefore, this study dealt with forms of space of the welfare facilities for the aged in Japan that are being suggested as a plan to solve the problem of supporting the aged. Japan who has similar Confucian culture like Korea experienced the aging of population 30 years earlier and enactment of law 20 years earlier than Korea. Therefore, Korean policies, systems and standards for welfare of the aged have been following Japanese welfare development model. This study analyzed the small-scale multifunctional welfare facilities for the aged in Japan before founding them in Korea to adapt the facilities that are compatible in domestic circumstance.

클러스터링 기법은 다양한 분야에서 이용되어 왔으며, 통계 기반 기계번역에서도 익히 사용된 기법이다. 그러나 기존의 연구에서는 깊이 있는 문법적인 분석 없이 기계학습 기법을 사용하거나, 문장구조의 정보를 사용하더라도 정규식을 이용하여 판별하는 선에서 그치는 경우가 많았다. 본 논문에서는 각 문장의 의존관계 문법에 따른 구조와 조사 등의 품사 정보를 사용하여 문장구조를 파악하고 유형별로 분류하여 각각에 특화된 언어모델을 획득하는 방법과, 이를 구 기반 통계기계번역에 추가적인 정보로 사용하여 번역성능을 향상하는 데 이용하는 방법을 제안한다.

A state or the arts in Japanese chemical process control is reviewed based on experience in applying advanced process control schemes to several industrial chemical processes. The applications validate model predictive control (MPC), the most popular advanced control scheme in the process control community, as, indeed, a powerful and practical control algorithm. However, at the same time, it is elucidated that MPC can solve only the control algorithm part of the problem and one needs chemical and systems engineering aspects to solve the entire problem. By illustrating several industrial process control problems, the need for chemical engineering aspects as well as the future direction for process control are addressed, especially in light or current attitudes toward product quality.

In this paper, We present a new nonlinear adaptive control law using a disturbance accommodating control (DAC) observer for a Japanese automatic landing flight experiment vehicle called ALFLEX. A future spaceplane must have ability to deal with greater fluctuations in the stability and control derivatives of flight dynamics, because its flight region is much wider than that of conventional aircraft. In our previous studies, digital adaptive flight control systems have been developed based on a linear-parameter-varying (LPV) model depending on dynamic pressure, and obtained good simulation results. However, under previous control laws, it is difficult to accommodate uncertainties represented by disturbance and nonlinearity, and to design a stable flight control system. Therefore, in this study, we attempted to design a nonlinear adaptive control law using the DAC Observer and inverse dynamic methods. A good tracking property of the obtained system was confirmed in numerical simulation.
