Voice therapy after post-thyroidectomy dysphonia is designed to improve glottal closure without supraglottic hyperfunction by development of abdominal support for breathing and intrinsic muscle strengthening exercises. Regarding voice therapy of unilateral vocal fold paresis/paralysis, several techniques such as head positioning, digital manipulation, pushing and pulling method are used for trial or temporary therapy. And the holistic voice therapy such as LSVT, Accent method, VFE are useful for hypofunctional voice disorders. These may be effective interventions as a temporary improvement until normal voice recovers or may provide the essentials for long-term rehabilitation.

The purpose of this study was to investigate the dynamics of dating violence among male and female adolescents. Out of 1205 high school students. 90.6%(n=1092) was included for the final analysis. 120 students(11.9%) reported to have experienced physical violence with a dating partner at least once or more. The most frequently used forms of violence were pushing and grabbing. Both of aggressors and victims interpreted the violence as an expression of love and affection. Coping behavior of victims were quite passive, while aggressors tried to apologize and to make-up. Most of victims were angry about violence. while aggressors felt sorry for their behavior. 72.5% of respondents reported that the relationship remained unchanged or got better after the violence. while 26.7% answered their relationship was terminated or got worse. 157 respondents(14.4%) reported to have experienced psychological violence at least once or more. Shouting and insulting language or behavior were most frequently used. Coping behavior of victims was mostly negotiation and communication. Based on the findings of this study, suggestions were made in regard to student guidance and counseling for dating aggression.

우리는 딥펜나노리소그래피에서 일어나는 박막 성장에 관한 잉크 확산 모형을 랜덤 워크 방법을 사용해 구현하였다. 분자동역학 연구를 바탕으로 제안된 hopping down, serial pushing, 단일 밀림 길이를 고려한 모형에 따른 박막 성장 특성을 비교하였다. 모형에 따라 그 박막 성장 특성에 확연한 차이가 있음을 발견하였으며, 잉크 분자와 기판 사이의 결합력이 중요한 변수임을 확인할 수 있었다. 그리고 원자힘현미경 탐침에서 떨어지는 잉크 분자의 속도와 단일 밀림 길이에 따른 박막 성장 차이를 알아보았다. 단일 밀림 길이가 커질수록, 탐침에서 떨어지는 잉크 분자의 속도가 빨라질수록 가지 모양의 박막이 형성됨을 알 수 있었다.

The purpose of this study is to investigate the incidence and dynamics of permarital abuse among never-married college students. 21.3% of 497 male and female respondents reported that they had experienced premarital violence at least once. Types of violence most frequently used were pushing or shoving slapping and throwing objects. It is interesting that both victims and aggressors interpret violent acts as expression of love most of all. Behavioral response to violent acts were to try to make up to talk to the partner and to apologize. In general the respondents had negative attitudes toward violence in premarital and marital relationships. Males showed more positive attiutudes toward violence than females. This sex difference appeared to have some inflence on marital abuse, In is suggested that counseling program and shelter for victims of severe violence need to be developed.

This paper presents a new loop shaping technique for design of robust optimal PID controllers in order to satisfy the performance requirements. PID controller can be designed by selecting the suitable weighting factors Q and R. This technique is developed by pushing all two zeros formed by PID controller closely to a larger pole of the second order plant. As a result, a good loop shaping is achieved in the high frequencies region on the Bode plot. For the robust optimal tuning of PID controller for second order system, a new loop shaping procedure is developed via LQR approach.

Ridge expansion osteotomy(REO) procedure is used to widen the narrow ridge in locations that are too thin to permit the use of standard implant drills. The objective of this technique is to maintain, if possible, all of the existing maxillary bone by pushing the bone aside with minimal trauma. The author has used tis procedure on five patients who had narrow ridge in their soft maxillary bone. Fifteen implants were placed in sites needing ridge expansion using REO. The satisfactory results were obtained. The REO procedure is thought to be a safer and more conservative method of widening a narrow ridge. And this procedure is heatless, offers excellent tactile sensitivity, control, visibility, and takes advantage of available bone.

E-business including e-commerce boosts the competitiveness of corporations remarkably through the creation of new value added, positioning itself as the key to national competitive edge. Thus, advanced nations and international organizations such as WTO and OECD are structuring a positive support system for e-transformation. Korea also has been pushing for activating e-business at the government level since 2000. ECRC(Electronic Commerce Resource Centers) project is an efficient government initiative and inter-agency coordination in implementing e-Business policy for industry. This project has been sponsored by the MOCIE and operated through prime contracts with KIEC. ECRCs provide such services as educational training, technology transfer, consulting and information service related to e-Business for industry. They had given the digital opportunity demanded by industry from 1997 but in these days there are many other new e-business activating projects in Korea. This paper sought to study a strategic reform plan of ECRC.

Recently companies are aggressively pushing ahead with integrating the systematical applications of internal and external information systems such as Data level, Application level, Process level in the company, Process level between companies. The EAI solution is generally considered as the necessary tool to integrate companies, but the appraisal standard for the EAI solution has not yet settled in Korea, so the companies have difficulty in deciding whether to adopt the EAI solution or not. Through this report, we first introduce the KRA Project as the best practice in making an application of the settled standard to evaluate and adopt the EAI solution, and then suggest that it can be adapted to companies considering applying to the EAI solution.

We propose a planning algorithm to automatically generate a robust behavior plan (RBP) with which mobile robots can achieve their task goal from any initial states under dynamically changing environments. For this, task description space (TDS) is formulated, where a redundant task configuration space and simulation model of physical space are employed. Successful task episodes are collected, where $A^*$ algorithm is employed. Interesting TDS state vectors are extracted, where occurrence frequency is used. Clusters of TDS state vectors are found by using state transition tuples and features of state transition tuples. From these operations, characteristics of successfully performed tasks by a simulator are abstracted and generalized. Then, a robust behavior plan is constructed as an ordered tree structure, where nodes of the tree are represented by attentive TDS state vector of each cluster. The validity of our method is tested by real robot's experimentation for a box-pushing-into-a-goal task.

Most psychophysical studies in manual material handling (MMH) have paid more attention to two-handed MMH activities than to one-handed MMH activities. Also, studies are involved only with single MMH activities - lifting, lowering, carrying, holding, pushing or pulling. Very few studies are reported on the determination of workers' capacities for combinations of one-handed MMH activities (lifting a box, then carrying the box, and lowering the box). The objective of this study was to find the psychophysical and physiological responses of human subjects from a simulated industrial task involving one-handed and two-handed combined tasks. The capacities that were determined as the maximum acceptable weight workloads for 1 hr work period for one-handed and two-handed combined tasks - lifting a box from floor to knuckle height, carrying the box for 4.3 m, and lowering the box from knuckle to floor height - were determined psychophysically under three frequencies: six handlings per minute, one handling per minute and one handling per five minutes. In addition to maximum acceptable weight, heart rate and RPE values on wholebody, back, and arm were also measured as responses.
