Background : In order to recognize the problems of current Korean physical therapy which does not conform to the current trend of modern society and to suggest improvement directions, we will establish a law for exclusive use of physical therapy that can guarantee the health rights of the people and contribute to the development of Korean physical. Methods : Korea's current physiotherapy system is compared with OECD member countries and WCPT member countries, and considering the expected effects and necessities that arise when the sole law is enacted, the sole law for the global trend is presented. Result : If the sole law is enacted and the physical therapist is treated solely, the effect is as follows. 1. Provision of high-quality physiotherapy services through establishment of physical therapy expertise 2. Convenient service provision 3. Reduced treatment costs due to reduced National Health Insurance fiscal expenditure 4. contributing to the improvement of medical welfare for the elderly and the disabled 5. Decreased unemployment rate due to job creation.

This study was described as midwife's role and obstacle of midwife's role expansion. Midwife as primary medical personal who practices for a mother and infant health care and promotion of mother infant interaction. As the trend of increasing natural childbirth, midwifery has to provide childbearing care those who want delivery in a midwifery center. This study conducted to survey for 44 midwives who work at the midwifery center. The results of the study as fellows. 1. Most of the midwives role was care of pregnancy, delivery, postpartum women and babies. Another role was conducted educational classes childbirth, breast feeding, contraception and sexual education. 2. Some midwives role perform breech, vaccum delivery, episiotomy and suture, pitocin induction and augmentation, ultrasonogram, giving medication, anesthesia, collecting specimen from Pap smear and vaginal discharge. Midwife perform these roles without medical law support. 3. Most of the obstacles of the midwife role was the medical law limitation. Midwives want revise medical law to perform simple treatment for childbearing women and babies. 4. Half of the midwives refer cases to medical doctor in case of complication of women and newborns. 5. Current frequency of home birth rate is slightly higher than before and me cases like to have delivery under water. Finally, midwife and midwifery have to prepare to meet childbearing woman, baby and family's need. For activation and expansion of midwife's role, every midwife has to be aware of medical law accurately and they must know what practice they can do and what practice they can not do.

As Korea's economy is entering a period of gradual growth, rate of growth on the construction market is becoming slow like that in developed countries. Remodeling construction market will be gradually expanded due to change in the social environment and diversification of individual demand. This study aims to promote the status of building equipment field with corresponding strategies based on the current situation that the importance of building equipment field is emphasized. Although it is desirable that building equipment construction companies lead remodeling construction, the building equipment part of general construction companies take the important role may be a advisable way, because the technology of building equipment construction companies is a little insufficient. Though building equipment field has become more important, the number of credits and professor of the field is still small than other fields of architectural engineering. More practical curriculums are necessary to meet the expectation of companies. Mechanical part of building equipment construction does not have independent law otherwise the other parts of building equipment construction. Establishing the independent law is urgent to promote the remodeling construction technology.

A seawater pumps in the nuclear power plant is responsible for providing cooling water to other components all the time. Because of the depreciation, the seawater pump with current impeller consumes too much power for maintaining the total head. Therefore the objective of this study is to reduce power with maintaining certain the total head by cutting the current impeller. By using a commercial CFD code, FLUENT, the overall performance of seawater pump with current and modified impeller was simulated. Also Affinity law was applied at pumps with various impeller diameter and evaluated the validity of the affinity law. The numerical results show that the pump efficiency is quite irrelevant to the diameters of the impellers and the pump efficiency becomes worse over the designed flow rate. And affinity law result and numerical one show good agreements at small change of impeller diameter. One of the impeller diameters was decided to modify and was applied to the nuclear power plant with the numerical study above.

This paper deals with a robust semi-active control algorithm which is applicable to a semi-active suspension with a multi-state damper. Since the controllable damping rates are discrete in case of a multi-state semi-active damper, the desired damping rate can not be produced exactly even if force-velocity relations of a multi-state semi-active damper is completely known. In addition, damping characteristics of the semi-active dampers are different from damper to damper. A robust nonlinear control law based on sliding control is developed. The main objective of the proposed control strategies is to improve ride quality by tracking the desired active force with a multi-state damper of which the force-velocity relations are "not" completely known. The performance of th proposed semi-active control law is numerically compared to those of the control law based on a bilinear model and a passive suspension. The proposed control algorithm is robust to nonlinear characteristics and uncertainty of the force-Velocity relations of multi-state dampers.

Most metallic materials and alloys show rate independence or negative rate sensitivity in some temperature region when dynamic strain aging occurs. It is generally recognized that negative rate sensitivity is an essential feature of dynamic strain aging that can depend on strain and/or strain rate. The unified viscoplasticity theory based on overstress is applied to reproduce a change of rate sensitivity type that depends on strain or strain rate. This is accomplished through the introduction of a single new term in the growth law of the equilibrium stress, which is a tensor valued state variable of the model. It is also shown that the new term can be used to reproduce a dramatic increase of rate sensitivity in dynamic plasticity.

The purpose of this study was to delve into all sorts of literature concerned in a bid to suggest how the Public Law Enforcement and private Security sector could join forces in preventing crimes and guaranteeing the safety of people. Quite naturally, crime has increased greatly to become one of the major social problems. Crime has been conventionally recognized as 'something' to be prevented and controlled by public law enforcement. However, the rate of crime increase has been so rapid that public law enforcement alone could not effectively control the everincreasing and diversified crimes in our society. To serve as a qualified partner for the police, private security industry should strive to secure excellent manpower and provide education for workers to improve their qualifications. Specifically, they should put sustained efforts into diversifying the types of security business and creating a new market to extend their scope of business and become more competitive. Intensified collaboration between the Public Law Enforcement and private Security security sector is expected to create new synergy in addressing people's needs for safety and enhancing their quality of life.

Because the health care or medical sector has such characteristics as publicity, professionality, and exclusivity, it cannot be left to the free market system. As a consequence, the state has restricted the establishment of medical institutions in order to protect the life and health of people. Also, the medical law has regulated to permit the establishment of medical institutions by only medical personnel and a few corporate bodies and to ban the establishment of medical institutions under disguised ownership as well as double opening of medical institutions by medical personnel. Nevertheless, there are still many cases that non-medical personnel have dominantly established medical institutions under disguised ownership of other medical personnel or nonprofit corporation. Because they are willing to recover their investment costs as soon as possible, these illegally established medical institutions are likely to make patients undergo unnecessary tests or to perform the excessive treatments and, as a result, are likely to cause infringement on the health and lives of the people. In addition, even if the misconduct is uncovered, the rate at which the costs already paid is very low and, as a result, the damages are straightly connected to the people's loss. On the other hand, there are also increasing number of cases that medical personnel or nonprofit corporations are establishing medical institutions against the medical law regulations. The examples of this illegality are also the double opening of medical institutions and the establishment of medical institutions under disguised ownership by medical personnel or nonprofit corporations. And the damages in these cases may not differ from those in the above cases. In this study, regarding medical law regulations restricting opening a medical institution, I will review the intent of those regulations, the type of violations and criminal punishments, and the possibility of recovery from unlawful profit by the National Health Insurance Act. And then, I would like to find a way for rational improvement of each.

Objective: The aim of this study is to investigate how well eye movement times in visual target selection tasks by an eye input device follows the typical Fitts' Law and to compare vertical and horizontal eye movement times. Background: Typically manual pointing provides excellent fit to the Fitts' Law model. However, when an eye input device is used for the visual target selection tasks, there were some debates on whether the eye movement times in can be described by the Fitts' Law. More empirical studies should be added to resolve these debates. This study is an empirical study for resolving this debate. On the other hand, many researchers reported the direction of movement in typical manual pointing has some effects on the movement times. The other question in this study is whether the direction of eye movement also affects the eye movement times. Method: A cursor movement times in visual target selection tasks by both input devices were collected. The layout of visual targets was set up by two types. Cursor starting position for vertical movement times were in the top of the monitor and visual targets were located in the bottom, while cursor starting positions for horizontal movement times were in the right of the monitor and visual targets were located in the left. Results: Although eye movement time was described by the Fitts' Law, the error rate was high and correlation was relatively low ($R^2=0.80$ for horizontal movements and $R^2=0.66$ for vertical movements), compared to those of manual movement. According to the movement direction, manual movement times were not significantly different, but eye movement times were significantly different. Conclusion: Eye movement times in the selection of visual targets by an eye-gaze input device could be described and predicted by the Fitts' Law. Eye movement times were significantly different according to the direction of eye movement. Application: The results of this study might help to understand eye movement times in visual target selection tasks by the eye input devices.

This study examines the critical features of 'Library Law' introducing the public library registration system. Accordingly, we conducted a document analysis to explore the legal meaning of registration in the 'Library Law'. We also surveyed participants in the gathering of 34 regional registration authorities to gauge their perception of the registration system. The analysis revealed that the registration with 'Library Law' is a permission system in terms of procedure and method but has the effect of notarization. The estimated national registration rate is 26 percent. The perception survey of the registration authorities' officials exposed the registration-related problems such as inconsistency described in supplementary note, excessive workload, difficulties in staffing, and ambiguity in registration criteria and target. To remedy these problems, we proposed an alternative method for the government to increase the effectiveness of 'Library Law'.
