The balcony of our apartment building consists of unique construction similar to double skin. It is announced broadly that double skin is very effective system in improvement of natural ventilation and indoor thermal environment, and outdoor sound protection. So, for the improvement of indoor climate and energy saving, many peoples studied about environmental performance of our balcony construction. This study focus on shaft box facade, special form of box window construction. It consists of a system of box window with continuous vertical shafts that extend over a number of stories to create a stack effect. Proto-type was decided by analyzing various types of exiting apartments. Shaft box type balcony was created by setting up shaft space at a part of balcony. Air flow and contribution of air temperature were simulated, performance of shaft box type balcony was compared with existing balcony. Finally, we confirmed that shaft box type balcony has many possibility for improvement of indoor environment.

Five type boxes manufactured from cement(A), wood panel(B), charcoal-packed wood panel(C), plywood panel(D) and charcoal-packed plywood panel(E) were prepared. Relationship of preservation characteristic of strawberry and relative humidity, and properties of thermal and sound insulations in the boxes were examined. During the experimental duration, relative humidity in the cement box was highest and lowest in the charcoal-packed wood panel box. Weight loss of strawberry was greatest in charcoal-packed wood panel box and very little in cement box. In the boxes with charcoal-packed wood panel box and very little in cement box. In the boxes with charcoal, strawberry was preserved for 10 days without getting mold, but in cement box it was covered with mold in 3 days. The charcoal-packed boxes showed higher thermal insulation property than the cement box. There were no significant differences in the property of sound insulation among the 5 type boxes. Consequently, it is suggested that charcoal-packed wood panels can be used for a better ecomaterial.

This paper surveys the meaning of the pen name ′Yi Sang(李箱)′ in the light of the arbitariness of language and the relationship among names, observing in three ways how the images of ′Sang′ (Box) appear differently in his works. In Particular, we look into (1) the relationship between a box and its inner boxes, (2) the divisional relationship in the box, and (3) the relationship between the box and an outer box. In Yi Sang′s work, image (1) gives shape to the relationship between the writer himself and his ancestors who are responsible for his present existence. Image (2) gives shape to two internally divided Yi Sangs, and is symbolized as a mirror that reflects two selves. Image (3) gives shape to a relationship between himself in the closed world and other people and/or a bigger outside world. All these symbolic relationships are fully represented in his work "Nalgae" (The Wing)". What is interesting is that Yi Sang has already employed these box images in his earlier poetry "Geonchuk-muhan-yukmyeon-gaucho" (Infinite Architectural Hexagon). furthermore, by visualizing his name as a sqaure($\square$), he means to suggest the intentional image of his pen name as a ′box′.

The ubiquitin-proteasome system is one of the major protein turnover mechanisms that plays important roles in the regulation of a variety of cellular functions. It is composed of E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3 ubiquitin ligases that transfer ubiquitin to the substrates that are subjected to degradation in the 26S proteasome. The Skp1, Cullin, F-box protein (SCF) E3 ligases are the largest E3 gene family, in which the F-box protein is the key component to determine substrate specificity. Although the SCF E3 ligase and its F-box proteins have been extensively studied in the model yeast Saccharomyces cerevisiae, only limited studies have been reported on the role of F-box proteins in other fungi. Recently, a number of studies revealed that F-box proteins are required for fungal pathogenicity. In this communication, we review the current understanding of F-box proteins in pathogenic fungi.

Recently, the underground reinforced concrete(RC) box structures have been increasingly built in Korea. In such structures, the heat of hydration may cause serious cracking problems. The RC box structures are classified in this category that needs much attention to control the hydration heat during construction, which causes the restraining effects on the boundaries. The purpose of the present study is to develop the rational construction method to control the thermal cracking problem of the box structures. In this study, the causes and mechanism of thermal cracking according to construction stages in the RC box structures are thoroughly analyzed. The major influencing variables are studied through the finite element analysis which affect the thermal cracking of RC box structures. The research results of the present study can be efficiently used for the control of cracking of box structures during construction stages.

The middle diaphragm of box girder is to prevent the deformation of the cross section of box girder, to distribute load produced at upper flange onto the both sides of web. But if inner space of box girder is barred by the middle diaphragm, it is impossible to use in inner space of box girder and it is felt constraint on maintenance-management. The effect of middle diaphragm of box girder is intended to be expressed by the stiffness of diaphragm in comparing the diaphragm with opening of box girder with diaphragm without opening of box girder through the experiment.

Yangroyun(養老宴), the ceremony for elderly people, originated with the ancient chinese, but the ceremony was held as almsgiving in the early period of Three Kingdom - Shilla.Goguryo.Backje. During the period, a king participated in the ceremony and gave elderly people grain and cloth. Also, in the unified Shilla dynasty, as it were. According to establish the aristocracy in the Three Kingdom Period, Yangroyun became the royal ceremony. In Goryo dynasty, Yangroyen was developed as a ceremony for awarding a person with filial piety prizes. In Chosun dynasty, Yangroyun was peformed in the rigid regulation. It was begun from the king Sejong, According to$\boxDr$Kyungkukdaejeon(經國大典)$\boxUl$, Yanroyun was held in September of the lunar year for over eighty years old, and queen held a banquet for the wives of the elderly. According to $\boxDr$Chosunwangjosilrok(朝鮮王朝實錄)$\boxUl$,$\boxDr$Gisaji(耆社志)$\boxUl$, and $\boxDr$Jungbomunhunbigo(增補文獻備考)$\boxUl$, Yanguroyun held totally eighty times in Chosun dynasty, however, in the late Chosun dynasty, Yangroyun was held few times.

In this study, three signal control strategies such as Bike box, Hook-turn, and 6-phase were assessed for various traffic conditions at signalized intersections incorporating bicycle left-turn traffic. Results showed that the size of a waiting zone mainly affected the performance of signal control in both Bike box and Hook-turn. Both Bike box and Hook-turn yielded an identical vehicle delay, but Bike box produced less bicycle delay than Hook-turn by 2.5~29.9 sec/veh for undersaturated traffic conditions. For saturated traffic condition, Bike box produced less vehicle delay than Hook-turn and 6-phase strategies, but bicycle delay was found to increase at the 700 vph of bicycle traffic compared to 6-phase. Bicycle delay was greatly increased under Hook-turn and Bike box strategies when bicycle traffic was greater than 300 vph and 500 vph, respectively. It was also shown that bicycle delay could be significantly reduced by providing appropriate size of queueing space. In addition, Bike box was likely to yield less vehicle and bicycle delay than Hook-turn for traffic volume patterns investigated in this study.

In this study, the parametric analysis for the buckling behavior of plates stiffened with the new type(${\Box}$ type) ribs was performed. Changes of the buckling capacity according to dimensions of ${\Box}$ type ribs show certain behaviors, so that the system to find the section of ${\Box}$ type ribs under the specific buckling capacity can be proposed. Applying this system to the steel deck of existing bridges, more economic sections of ${\Box}$ type ribs rather than that of closed ribs can be obtained. Therefore, the economic section of steel deck having the required buckling capacity can be designed by using the proposed system of ${\Box}$ type ribs.
