This study has been conducted to predict the ultimate moment capacities of double angle connections with various angle thicknesses and bolt gage distances. Considering the results of experimental tests conducted previously, a simplified analytical model is suggested in this research. In addition, some basic data are also provided for structural engineers to design a double angle connection preliminary.

1990년대 초, 미국의 봉쇄정책과 구 소련의 붕괴로 당장 먹고살기도 힘들었던 쿠바. 하지만 쿠바인들은 좌절하지 않고 직접 먹을거리를 해결하기 위해 농기구를 들었다. 너도나도 밭을 일구고, 친환경 농업에 사활을 걸었다. 그렇게 10여 년이 지난 뒤 나락에 빠졌던 쿠바에 푸른 농업혁명이 일어났다. '유기농 강국'으로 세계의 주목을 받게 된 것이다. 특히, 쿠바의 수도 하바나(Havana)는 유기농 도시농업의 중심지다. 하바나 시민들은 발코니와 집 텃밭, 인근 공터 등에 곡류와 채소를 키운다. 유기농 농산물 섭취를 통해 건강도 지켜나가고 있다. 곤궁했던 경제위기를 건강한 녹색혁명으로 뒤바꾼 것이다.

A Hangul input method consists of two core components: key layout for primitive units (Natja), and binding rules to form more complex, composite units from primitive ones. However, careless design and implementation of an input method may result in ambiguity and inability of contiguous typing, when it comes to handle composite Hangul units. This is due to the collective nature of Hangul, namely, existence of implicit boundaries between units and syllables. This issue gets more challenging for the context-dependent 2-beolsik method, mobile environment having significantly fewer keys, and yet addition of the support for Old Hangul. For the sake of the management of complexity, we devised a system in which the binding rule is divided into two layers rather than one. Based on this concept, we implemented a tool program that, given the primitive units and their binding rules, generates input details of every composite unit and detects any potential ambiguity and conflicts. We presented the actual analysis result for Samsung Cheonji-in and KT Naratgeul, two of the most popular mobile Hangul input methods used in Korea.

Virtual Hangul keyboards like Chun-Ji-In, Narat-Gul, and QWERTY are based on eyesight recognition, in which input letter positions are fixed in the smartphone environment. The input method of a fixed-position style is not very convenient for visually impaired individuals. In order to resolve the issue of inconvenience of the Hangul input system, we propose a new paradigm of the finger-touch based Hangul input system that does not need eyesight recognition of input buttons. For the convenience of learning the touch-motion based keyboard, finger touches are designed by considering the shape and frequencies of Hangul vowels and consonants together with the preference of fingers. The base position is decided by the first touch of the screen, and the finger-touch keyboard is used in the same way for all the other touch-style devices, regardless of the differences in size and operation system. In this input method, unique finger-touch motions are assigned for Hangul letters that significantly reduce the input errors.

It takes a lot of time or is even impossible to communicate for people with physical disability and/or speech impairment. Augmentative and Alternative Communication System is an important computerized tool that makes it possible for those people to communicate. Since not only speech impaired people, but also people with other physical disability cannot use conventional computer input devices easily such as keyboard and mouse, so more simple input devices are need for them to communicate. Thus, in this paper, I designed and implemented a communication aid system, with which they can communicate with simple inputs. I collected frequently used sentences by people with disability and categorized them into 9 everyday language groups. With these categories, they can select any sentence with few simple selections. If none of these categories includes the sentences they want, ChunJiIn keyboard is provided so that they can input the sentences, which can be added to the existing language groups for later use. The priority levels of the sentences in each group is constantly readjusted based on usage frequency so that the number of inputs can be reduced.

Three hundred and sixty two specimens of Plecoglossus altivelis were randomly sampled from Chunji Stream in Seogwipo, Cheju-Do, during the period from 25 Aug., 1973 to 14 Feb., 1974 to investigate the relationship between total length and dody weight as well as the condition factor during the spawning period. Results obtained are summarized as follows : The relationships between total length and body weight are calculated as below, respectively : $W=0.008639\;L^{3.1806}$ : Prior to spawning period $W=0.01830\;L^{2.7689}$ : During spawning period The above equations differ each other significantly. Nevertheless, the significant difference is not found between sexes. The mean body length decreased during the spawning season. The fact seems to be caused by the death of large fish after spawning. The condition factor was $13.45\%_{\circ}$ on the average in August. The value decreased continuously from September, giving the minimum mean value of $10.25\%_{\circ}$ on Nobember 29. But the value increased again, showing $11.18\%_{\circ}$ in next February. Majority of the fish survived until next year was small ranging from 11 to 12cm in total length.

For a quick and easy way of writing Hangul in hand-held devices, we analyzed the combination rules of Hangul alphabets that we constructed a small set of Hangul alphabets that combines a whole set of Hangul alphabets. Hangul consonants are generated from base set of consonants with function keys and vowels are constructed from eight base set of vowels by combination rules and stroke-adding rules. Especially, we adopted an easy error-correction method to resolve the inconvenience of using a delete key for vowel harmony errors. Futhermore, we diversified the input method of diphthongs for user-friendliness by minimizing the efforts of teaming vowel combination rules. We compared our method with previous methods of 'Chon-Ji-In' and 'Na-Rat-Keul' that the proposed method is better than the previous methods in input speed and error correction functionality.

Since long ago, there has been a saying that "Drink water to quench thirst, drink alcohol to remove anguish and anxiety, and drink tea to recover from fatigue and refresh mind." Tea is really better for body and mind than water when it is drunken long and is valuable Jinda(眞茶) given by mother nature. In particular, curing tea reflecting characteristics of climate changes in all seasons helps in keeping health. Since tea contains the Yin-Yang system, which is a philosophical ideology of ancient people, old predecessors knew which tea they should brew and drink for curing in harmony with Yin and Yang. As a factor that influences component changes of tea, a complex interaction of heaven, earth and man is important and especially, mind of a person to handle tea is most important. Tea is a natural curing drink, which plays a role as a bridge between humans and nature.

We are so used to the concept of the term 'space' that we do not question its conceptual validity. However, this paper argues that the notion of space prevailing all over the world, is not a universal concept that can be applicable to all architectures of the world, but is a particular concept that is generated from the Western way of thinking. This paper alms to identify the conceptual structure of the idea of space as it is originated in the tradition of the West, and, as an alternative view of space, tries to identify the nature of the view of space perceived in the tradition of the Eastern architecture. Comparison of the two views, that of the East and the West, and their meaning in the future of architecture, is another task to discuss in this paper. To be able to clarify the meaning of space in East Asian tradition, a set of new perspective of understanding of space was invited. They are ; 1. sky-earth(天地); insisting that the notion of space should be replaced within the context of sky, which is one half of sky-earth totality 2. energy of the air (空氣), space is not empty part inside of a building, but is a dynamic condition of air that is a part of the sky which always exist in form of energy 3. place(자리): instead of space, which, basically. is a man-made concept, idea of place is necessary, which include not only space but also earth Such concept of space which is different from the notion of space of the West, is meaningful not only to identify the idea of space in the East, but also to be able to contribute for more dynamic, varied, and balanced understanding of space.
