A Reasonable lighting should be provided for doing night work. All works far construction site can be exposed to potential hazard at night work The purpose of this study is to provide a standard of the lighting against accidents due to insufficient lighting at site. one pilot tea one at building work site, one at mad work site of it have been conducted for figuring out illumination change depending worker's activity direction, using lux checker to show it as numerical indication. The direction are changed with a range of 30, 60, 90, and 135 degree to be checked at site. Tests results show that $10\%\;and\;15\%$ of lighting could be decreased by changing the working direction of works at site. Therefore, steep slope place, cave work and backside of structural elements such as a column, deep beam should be considered for keeping sufficient and reasonable lighting. It is found that $50\%more$ illumination Lux needs f3r civil work than for building work.

The skin barrier is an important part of an ostomy product, holding the ostomy bag in place and protecting the peristomal skin. Skin barriers help protecting the peristomal skin from excrements and secretion, thus keeping the skin physiology intact by absorbing or permeating sweat. The vocabulary for the skin barrier has been standardized by ISO 24214, but there is no standard related to the skin barrier in Korea. We investigated the academic and commercial documents related to the skin barrier, and conducted a survey for appropriate korean vocabulary for standard. We propose Korean standard vocabulary for skin barrier terms defined in ISO 24214:2006.

The kinetics of the addition of X-substituted benzylamines (BA) to Y-substituted Benzylideneacetylacetones (BAA) have been investigated in acetonitrile at $25.0^{\circ}C$. The reaction is studied under pseudo-first-order conditions by keeping a large excess of BA over BAA. The addition of BA to BAA occurs in a single step in which the addition of BA to $C_\alpha$ of BAA and proton transfer from BA to $C_\beta$ of BAA take place concurrently with a four-membered cyclic transition state structure. The magnitude of the Hammett ($p_X$) and Bronsted ($\beta_x$) coefficients are rather small suggesting an early tansition state (TS). The sign and magnitude of the cross-interaction constant, $p_{XY}$ (= -0.49), is comparatible to those found in the normal bond formation processes in the $S_N2$ and addition reactions. The normal kinetic isotope effect ($K_H/K_D$ > 1.0) and relatively low $\Delta$H^{${\neq}$}$ and large negative $\Delta$S^{${\neq}$}$ values are also consistent with the mechanism proposed.

The burgeoning growth of real-time applications, such as interactive video and VoIP, places a heavy demand for a high data rate and guarantee of QoS from a network. This is being addressed by fourth generation networks such as Long-Term Evolution (LTE). But, the mobility of user equipment that needs to be handed over to a new evolved node base-station (eNB) while maintaining connectivity with high data rates poses a significant challenge that needs to be addressed. Handover (HO) normally takes place at cell borders, which normally suffers high interference. This inter-cell interference (ICI) can affect HO procedures, as well as reduce throughput. In this paper, soft frequency reuse (SFR) and multiple preparations (MP), so-called SFRAMP, are proposed to provide a seamless and fast handover with high throughput by keeping the ICI low. Simulation results using LTE-Sim show that the outage probability and delay are reduced by 24.4% and 11.9%, respectively, over the hard handover method - quite a significant result.

This research examined the residents' behavior in using space, focusing on the kitchen area where there was the most change, in order to understand the transition of living culture through the ages. The following findings were obtained: 1) Today's apartment residents prefer 'Island' style which is located a separate counter and work space. Thus the kitchen m is now being recognized as a place spacious, and where the whole family can participate. 2) The usage of the kitchen is not only limited to cooking or keeping household goods but also broadened to washing, private life, happy home circle, inviting guests etc. Especially, family union or inviting guests in the kitchen is more frequent as the houses become larger, private refreshment or reading in the kitchen is proportional to income and to people living in homes where the kitchen and dining room is divided independent 3) Looking at the dietary life styles of today's apartment residents, there are more well-being type and tradition type than prosessed type. This trend is portional to the resident's standard of education and the size of the apartment, thus making a significant influence.

The purpose of this study is to find out the transition of meaning and terminology of support spaces in Korean houses based on preliminary studies and analysis of Korean novels. The major findings are as follows. The planning and location of the kitchen and its support spaces developed slowly until the 1970s. Buok has been the terminology of support spaces that appeared often and continuously in novels. The word Bongdang was mentioned only before the 1900s. The new words such as Sikdang. Buokaband appeared after the 1960s,. Jubang appeared after the 1980s. The meaning of kitchen space described in novels were various. Thpically the kitchen was used for cooking washing dishes keeping kitchen utensils foods and miscellaneous goods. Exveptionally the kitchen was the place for quarreling with others weeping secretly hiding washing clothes etc. The kitchen was also a symbol of the wealth of the family but many kitchens were usually described in novels as the unpleasant places. Even though most users of the kitchen in novels were women men also used the kitchen in novels were women men also used the kitchen without any restrictions. however the activities of men and women of the upper class in the kitchen were never described in any novels.

This paper concerned with the Honsu(婚需) norms of urban residents in Korea, and was designed to suggest a solution to solve the current problems of the extravagant Honsu with the changes int he customs related to Honsu. Data collected through interviews with questionaire were analyzed statistically by X2-test, ANOVA, Scheffe-test, factor analysis, cluster analysis and product moment correlation coefficients using SPSS PC+ program. Factors of HONSU norm, was characterized into 3 types, exchangabilities and focusing on groom's family, preparation of goods for housekeeping, and independence from parents and individualism. HONSU was found to be regarded as the basis for better life for the new family provided by their patents in terms of the family norm. The current problems of extravagant HONSU seems due to the family norm. Factors of HONSU norms could be grouped into 4 categories by the cluster analysis. They are 1)the preparation of basic house-keeping items for independent family, 2)an opportunity to secure an economic base for the new family, 3)an opportunity to show off their wealth by selecting easily exchangable goods, and 4)others who select items based on their personalities. An oppportunity to show off their wealth by selecting easily exchangable was the cultural norm of Honsu, and it was found that urban housewives had almost uniform thoughts about Honsu. Consideration of items for individuals' needs and independent life took place in deciding on Honsu for all four types of couples although the weight given to this consideration showed difference. Preparation for the new family and individual needs were the common grounds of HONSU norms in all categories through the weight was different.

The mine-detection system, which is one of the various mission equipments for Ground Vehicle System, detects mine under the ground. The mine detection sensors comprised of Metal Detection(MD) sensor and Ground Penetration Radar(GPR) are attached on the end of the multi-DOF manipulator. The manipulator moves the sensor to sweep mine areas keeping the pre-determined distance between the sensor and ground to enhance mine detection performance. The detection system can be operated automatically, semi-automatically and manually. When the detection system is operated automatically, the sensor should avoid collisions with unexpected obstacles which may exist on the ground. Two types of ultra-sonic sensors were developed for the mine detection sensor system to keep the appropriate gap between sensor and the ground to avoid the obstacles. Also, mine place marking device was developed.

Sung Yung Shin was adopted as a Korean infant to an American family. She is now one of the most important writers in Asian American literary field. This paper analyzes the characteristics of her literature, focusing on Skirt full of Black (poetry)and Cooper's Lesson(children's book). Sun Yung Shin uses collage in Skirt full of Black as an effective rhetorical device because it can express her experience as an adopted other in the multicultural American society. She rewrites the fairy tale of Swan Prince in the viewpoint of silence. For a yellow Asian adopted woman, speaking is suppressed. In the end, the attempt to escape from silence is the writer's resisting activity, and the rewriting of the tale is her questioning in place of the princess. I analyses Cooper's Lesson in the viewpoint of transcultural assimilation. Cooper's lesson is accomplished not by his white father but by a Korean settler, Mr. Lee. Cooper's family is a hybrid composed of white American father, Korean mother, and their half son. So this family has many complicated difficulties, though it's small. Mr. Lee who accepted a new language to establish a new identity teaches Cooper the importance of cultural assimilation, which is not a one-sided integration to dominant culture but an intercultural communion while sustaining each culture's singularity. Cooper learns that he should live in an harmonious and balanced life in a multi-cultural society while keeping his own subjective point of view.
