The purpose of this study was to investigate the overall developmental characteristics of Korean children ages 0 to 8, and then explore specifically how children's social and emotional developmental levels are related to mothers' psychological states. This study was part of newly launched Boryung Baby Panel Study using web-based survey in 2011. The subjects were all mothers of 940 infants(0-2 years), 654 toddlers(3-5 years), and 484 school-age children(6-8 years) The mothers were asked to administer the web-based standardized developmental checklist for their child and fill out the questionnaires of psychological variables(life satisfaction, depression, parenting attitude, parenting efficacy, and parenting stress). The data was analyzed using descriptive analysis, t-test, and logistic regression for SPSS 20.0 windows. Major findings were as follows: 1. Infants(0 to 2) showed higher developmental level in cognition and fine motor skill domain compared to other domains. 2. Most toddlers(3 to 5) showed normal development in the most domain such as gross motor skill, fine motor skill, language, letter, number, self-help behavior. 3. In socio-emotional development domain, the ratio of risk or delay group were highest at both infant and toddler. 4. The 6-8 years old children that belong to risk group by the result of SDQ(emotion and behavior assessment) were also relatively high. 5. The relation of the children's socio-emotional developmental level and the mother's psychological variables were reciprocal. Based on these findings, the implications and the limitations of current study were discussed.

A PC based software, the RTP Research Tool Box (RTB), was developed for IMRT optimization research. The software was consisted of an image module, a beam registration module, a dose calculation module, a dose optimization module and a dose display module. The modules and the Graphical User Interface (GUI) were designed to easily amendable by negotiating the speed of performing tasks. Each module can be easily replaced to new functions for research purpose. IDL 5.5 (RSI, USA) language was used for this software. Five major modules enable one to perform the research on the dose calculation, on the dose optimization and on the objective function. The comparison of three cost functions, such as the uncomplicated tumor control probability (UTCP), the physical objective function and the pseudo-biological objective function, which was designed in this study, were performed with the RTB. The optimizations were compared to the simulated annealing and the gradient search optimization technique for all of the optimization objective functions. No significant differences were found among the objective functions with the dose gradient search technique. But the DVH analysis showed that the pseudo-biological objective function is superior to the physical objective function when with the simulated annealing for the optimization.

This study aims to examine associationistic psychology and psychological operation associated with each color image, then to study the relation between particular colors used in paintings produced by Gogh and Klimt in different times and these painters' psychology in a bid to explore the meaning and role of psychological operation of colors. The findings of the study indicated that red and blue colors represent mainly negative images, while yellow and orange colors represent mainly positive images and psychologies. Specifically, in the case of Gogh, red expresses anxiety, a negative image, yellow symbolizes passion, a major positive image of emotional liberation, dark and thick green and the green involving blue symbolize negative images, emptiness and despair, and blue represents negative images of internal desire conflicts, and screaming. Also, purple used together with white represents anxiety and depression. In the case of Klimt, red represents negative images of anger toward mother and suppressed energy, yellow, an alternative to gold color, symbolizes the positive image of hope, passion, desire and eroticism, the arrangement of strong gold and orange colors represents a color of psychological healing more than a color of hope. As such, colors used in paintings produced by modern Western painters express the physiological conditions, psychological feeling and emotion in life, at the time when the artists produced such works. It was found that colors are yet another language of expressing emotions, and symbolize the psychologies of the artists, indicating that colors have something to do with the painters' experience and emotional impulses.

Objectives : This paper studies Zhushang, which is the name of a disease found in excavated books. Zhusang is the first disease listed in Wushierbingfang, which is a medical textbook excavated at Mawangdui, and Zhusang was followed by diseases such as Jinshang and Renshang. The paper studies what disease each of the word is refering to in terms of graphonomy, and compared the difference of their treatment from other classical texts. Methods : The scope of the study of this paper includes the excavated textbooks that seem to contain any disease related to Zhusang, and the two major text books of these are Wushierbingfang and Wuweihandaiyijian. Then Shennongbencao jing, which is the one of the earlier books on herbology, and Bencao gangmu, which was written based on the former, wer used to make comparisons. Parts in Donguibogam that seem to be related to the parts in the excavated texts were also compared. The study was done by first performing historical research on the names of the diseases in the excavated books, and compared them with the contents of the classical texts. Results : The Zhushang discovered in Wushierbingfang refers to wounds caused by metal or wood. It was interesting how they created a word for diseases depending on the cause. Only Jinshang is found in Wuweihandaiyijian, and the fact that different causes gave way to different names tells us that they had corresponding treatment. The categorization of Zhushang, Jinshang, and Renshang is corresponded better in Donguibogam than Chinese medical books.

In emergency dispatching at 119 Command & Dispatch Center, some inconsistencies between the 'standard emergency aid system' and 'dispatch protocol,' which are both mandatory to follow, cause inefficiency in the dispatcher's performance. If an emergency dispatch system uses automatic speech recognition (ASR) to process the dispatcher's protocol speech during the case registration, it instantly extracts and provides the required information specified in the 'standard emergency aid system,' making the rescue command more efficient. For this purpose, we have developed a Korean large vocabulary continuous speech recognition system for 400,000 words to be used for the emergency dispatch system. The 400,000 words include vocabulary from news, SNS, blogs and emergency rescue domains. Acoustic model is constructed by using 1,300 hours of telephone call (8 kHz) speech, whereas language model is constructed by using 13 GB text corpus. From the transcribed corpus of 6,600 real telephone calls, call logs with emergency rescue command class and identified major symptom are extracted in connection with the rescue activity log and National Emergency Department Information System (NEDIS). ASR is applied to emergency dispatcher's repetition utterances about the patient information. Based on the Levenshtein distance between the ASR result and the template information, the emergency patient information is extracted. Experimental results show that 9.15% Word Error Rate of the speech recognition performance and 95.8% of emergency response detection performance are obtained for the emergency dispatch system.

Fine art and clothes have been closely connected since art became part of civilization. However, there relationship was one-sided rather than exchanging the essence of each other. In the $20^{th}$ century, modern art began to change. Artists started intervening clothes in their work as conceptual tools. In the 1960s, Marcel Duchamp started to study 'what is fine art?' He tried to perform anti-aesthetic work that denies traditional types and contents of fine art by reconsidering a concept of fine art that started a new chapter of conceptual art in the late $20^{th}$ century. Conceptual art is about concepts and ideas of the work rather than aesthetic and material concerns for the challenges traditional ideas. Conceptual art asks audiences for more active reactions. For these reasons, semi logical ideas and clothes became very important to conceptual art. This study categorizes and analyzes various roles of clothes in conceptual art. Conceptual arts since 1960 were studied in this research and the works of clothes were intervened were analyzed. The types of using clothes in conceptual art can be divided into 'ready made,' 'intervention,' 'data type,' 'language,' and 'action and process.' The different types were mixed together rather than used alone. Conceptual artists tried to deliver the characteristics and attributions of modern society through clothes. They expressed criticism of political society, anti war movements, absence caused by death, new lives, violated femininity, changed meanings of marriage, and absence of individual rights under the social system in their work. Clothes played their roles as concepts of various things including violated femininity, illusions of politicians, autocracy, new lives, social systems, and regulations.
