The current American Concrete Institute(ACI), Canadian Standard Associate(CSA) and CEB-FIP Model Code 2010 provisions on the shear strength of a simply supported deep beam suggest that deep beams should be designed using the strut-and-tie model. Although this is a useful methodology to design members in disturbed regions, the quality of the design is highly dependent on the truss model that designers create. However, Hong et al. derived the shear strength equations of reinforced concrete deep beams. This thesis investigates the validity of the current ACI, CSA and CEB-FIP code provisions on the shear strength of simply supported reinforced concrete deep beams by comparing them with the shear strength equations proposed by Hong et al. The comparison shows that all of these code provisions provide reasonable estimates on the shear strength of concrete deep beam members and the selection of an internal truss model plays an important role on the estimation of shear strength.

Sintered Nd-Fe-B magnets are widely used in many fields such as motors, generators, actuators, microwaves and so on due to their excellent magnetic properties. Many researchers have shown that the Nd-rich phase was essentially important for high magnet properties. In this study, we focused on controlling of the Nd-rich phase to enhance magnetic properties by the cyclic sintering process. Nd-Fe-B based sintered magnets were prepared by isothermal sintering and cyclic sintering processes. Magnetic properties and microstructure of the magnets were investigated. The coercivity was enhanced from 21.2 kOe to 23.27 kOe after 10 cycles of the sintering. The Nd-rich phase was effectively penetrated into the grain boundary between the $Nd_2Fe_{14}B$ grains by the cyclic sintering.

Objective : To determine the association between occupational stress and disordered eating problem in Korean female employees. Methods : We studied 1,452 female employees who attended mental health screenings. Using the Korean Occupational Stress Scale-Short Form (KOSS-SF) and 26-item Korean version of Eating Attitude Test, occupational stress and disordered eating problem were evaluated, respectively. Sociodemographic and clinical characteristics of those with disordered eating problem were examined. Multiple logistic regression analysis was performed to determine which subscale of KOSS-SF was associated with disordered eating problem. Results : Disordered eating problem was associated with interpersonal conflict [odds ratio (OR) 1.882, 95% confidence interval (CI) 1.138-3.112] among various kinds of job stresses. Lack of reward (OR 7.164, 95% CI 1.139-45.043) and insufficient job control (OR 1.953, 95% CI 1.119-3.411) were associated with disordered eating problem in the underweight and normal weight group, respectively. Conclusion : There is an association between occupational stress and disordered eating problem among Korean female employees.

Objective : This study was designed to evaluate the hypoglycemic effects of Helianthus tuberosi Rhizoma extracts and its optimum Heat processing conditions Methods : We investigated the Salivary ${\alpha}$-amylase, pancreas ${\alpha}$-amylase and ${\alpha}$-glucosidase inhibitory activities of extracts from Steam Heated Helianthus tuberosi Rhizoma Ext. The inhibitory activities of a 50% EtOH extract of Steam Heated Helianthus tuberosi Rhizoma Ext against ${\alpha}$-glucosidases were evaluated in this study. Inhibiting these enzymes involved in the absorption of disaccharides significantly decreases the postprandial increase in blood glucose level after a mixed carbohydrate diet. Furthermore, the postprandial blood glucose lowering effect of Steam Heated Helianthus tuberosi Rhizoma Ext. was compared to a known type 2 diabetes drug(Acarbose(R)) in a mice model. Steam Heated Helianthus tuberosus L. Ext significantly reduced the blood glucose increase after glucose loading. Results : The results were confirmed by real-time PCR that after treated with Streptozotocin in L6 cells, induced expression of GLUT4, after the steamed Helianthus tuberosus L. Ext. treated, observed its expression was increased. Steam Heated Helianthus tuberosus L Ext treated 4 hours in L6 cells, cytotoxicity was measured in MTT assay. Its toxicity were 5.7%, 9% and 11.3% at the treatment concentration $12.5{\mu}g/m{\ell}$, $25{\mu}g/m{\ell}$, the $50{\mu}g/m{\ell}$ respectively. Conclusions : Overall, the results of this study indicate that Hypoglycemic effect of Helianthus tuberosi Rhizoma caused by the Steam heat treatment, the optimum Heat processing condition is steamming at $121^{\circ}C$ for 30 min, and it will provide the basis for developing a useful dietary supplement for controlling postprandial hyperglycemia.

최근 광대역 무선 통신망의 보급과 소형 저장매체의 대용량화로 인하여 이동형 단말기가 주목 받고 있다. 이로 인해 이동형 단말기에 문자정보를 청취할 수 있도록 문자를 음성으로 변환해 주는 TTS(Text-to-Speech) 기능이 추가되고 있다. 사용자의 요구사항은 고음질의 음성합성이지만 고음질의 음성합성은 많은 계산량이 필요하기 때문에 낮은 성능의 이동형 단말기에 는 적합하지 않다. 본 논문에서 제안하는 분산형 음성합성기 (DTTS)는 고음질 음성합성이 가능한 코퍼스 기반 음성합성 시스템을 서버와 단말기로 나누어 구성한다. 서버 음성합성 시스템은 단말기에서 전송된 텍스트를 데이터베이스 검색 후 음성파형 연결정보를 생성하여 단말기로 전송하고, 단말기 음성합성 시스템은 서버 음성합성 시스템에서 생성된 음성파형 연결정보와 단말기에 존재하는 데이터베이스를 이용하여 간단한 연산으로 고음질 합성음을 생성할 수 있는 시스템이다. 제안하는 분산형 합성기는 단말기에서의 계산량을 줄여 저가의 CPU 사용, 전력소모의 감소, 효율적인 유지보수를 할 수 있도록 하는 장점이 있다. Recently portable terminal is received attention by wireless networks and mass capacity ROM. In this result, TTS(Text to Speech) system is inserted to portable terminal. Nevertheless high quality synthesis is difficult in portable terminal, users need high quality synthesis. In this paper, we proposed Distributed TTS (DTTS) that was composed of server and terminal. The DTTS on corpus based speech synthesis can be high quality synthesis. Synthesis system in server that generate optimized speech concatenation information after database search and transmit terminal. Synthesis system in terminal make high quality speech synthesis as low computation using transmitted speech concatenation information from server. The proposed method that can be reducing complexity, smaller power consumption and efficient maintenance.

This study aims to understand differences in what specialists groups think important to establish district units plans. The result of the study is as follows. There were differences in thinking by specialists on standards and procedure of establishment, characteristics of the plans. For the standards of establishment, there was a remarkable difference in thinking on the importance. In the search for the importance on the establishment procedure, the groups of architects, construction firms, researchers and professors & instructors thought listening to opinions of residents important and public officials considered review by the City Planning Council important. In the survey on characteristics of district units plans, the most respondents answered 'plans leaded by private sectors focusing on residents' and 'plans to practice for actualization of urban plans'. Public officials and researchers answered that district units plans should be practical plans for actualization of urban plans with strong characteristics of work. The groups of architects, construction firms and professors/instructors mostly thought that private sector leaded plans focusing on residents as characteristics of district units plans. It was understood that construction firms think that the parts related to conditions for construction across overall standards of establishment, procedure of establishment are important. The specialists who think that the plans should be private sector leaded plans focusing on residents on which the residents' opinions are reflected were the groups of architects and professors/instructors.

Purpose : The purpose of this study is to report the effect of Traditional Korean Medicine(TKM) on amenorrhea which oligomenorrhea has become worse. and to investigate the change of body temperature measured by Digital Infrared Thermographic Imaging(DITI). Methods : The patient in this case was 29-year-old female. The chief complain was amenorrhea which oligomenorrhea has become worse. We treated her by TKM. and evaluated the progress of symptoms by DITI. And then We compared DITI before treatment and after treatment. Results :After TKM treatment. the differences of temperature between Indang(印堂) and the four abdominal sites(CV4,6,12,17) were decreased on DITI. respectively. Conclusion : TKM treatment is effective on amenorrhea which oligomenorrhea has become worse. And DITI could be useful to assess the amenorrhea objectively. But more research should be needed.
