Objectives: The purpose of the study is to investigate the opinions of some local clinical dental hygienists on medical personnel of dental hygienists. It will be for provide the Future dental hygienist basic data necessary for medical personnel. Methods: A self-reported questionnaire was completed by 171 dental hygienists in Busan and Gyeongnam from December 1, 2017 to January 31, 2018. Structured questionnaires were uesd for analysis. The questionnaire consisted of general characteristics of the subjects(7 items), medical personnel necessity and opinions of dental hygienist(2 items), the opinions of distinction of the task between dental hygienists and other personnel(2 items), many frequency task in the dental clinic. The collected data were analyzed using frequency, percentage, descriptive statistics and ANOVA using IBM SPSS VER 20.0. Results: 89.5% of the dental hygienists required medical personnel of dental hygienist, the opinions on the necessity were as follows: 'role and quality improvement as oral health professionals', 'lack of legislation and application of dental hygienists duties'. There was no difference reason between dental hygienists and other personnel on duties, the reason were investigated to uncertainty of dental hygienist system, lack of dental hygienist workforce, dentists lack awareness of dental hygienist expertise. There was surveyed by the current many frequency duties in the dental clinic, assist for dental treatment, Oral health education and counselling, Preventive dental treatment. Conclusions: Legal guarantees for clinical dental hygienists work are absolutely required. Therefore, relevant government agencies and related organizations should resolve the contradiction of the legal system of medical law and medical technicians. The clinical dental hygienists should be promoted to medical personnel through the amendment of the medical law so that the duties practiced by the dental hygienist can be matched with the legal practice.

The soil behaviour can be represented by numerical modelling of element testing using diverse constitutive models. However, not all constitutive models allow the simulation of the stress-strain response at the critical state in granular soils with both contractive and dilative behaviour. Moreover, the accuracy of these models depends highly on the quality of the experimental data used for their calibration. This study addresses the modelling of the critical state behaviour of an alluvial natural soil from the Lower Tagus Valley (south of Portugal), known as TP-Lisbon sand, using the NorSand constitutive law. For this purpose, a series of numerical simulations of element testing was carried out using two algorithms performed in Visual Basic (VB) and Fast Lagrangian Analysis of Continua (FLAC). Moreover, this study presents the characterisation of of NorSand parameters from an accurate experimental programme based on triaxial and bender element testing. This experimental program allowed defining: (i) the critical state locus, (ii) the stress-dilatancy, and (iii) the soil elasticity of TP-Lisbon sand -all fundamental to calibrate the contractive and dilative behaviour of such alluvial soil. The results revealed a good agreement between experimental data and NorSand simulations using VB and FLAC. Therefore, this study showed that the quality of laboratory testing procedures and its good interpretation enables NorSand constitutive law to capture representatively the non-associated plastic strains, often expressed by the state parameter, allowing a representation of soil behaviour of alluvial soils within the critical state soil mechanics framework for different state parameters.

The friction factor distribution of commercial pipes vary according to the pipe type and size. The present paper developed the friction factor equations of power law by analyzing the data reported by Colebrook(1938). Generally, pipe design requires pump power, discharge or pipe diameter for each condition given. Yoo(1995b) has suggested the basic equations for the explicit design of uniformly rough pipe and Yoo and Kang(1996) have refined those equations for the cases of uniformly rough pipe on a sloping bed with a pumping power. Furthermore Yoo and Kang(1997) have studied the design of commercial pipe for a general case. The approach gives relatively accurate solutions, but the equations obtained are rather complicated. In the present study two types of power law are developed for the friction factor of commercial pipe, and explicit forms of equations are generated by applying the power law friction factor equations for the simple design of commercial pipes.

In this article, legislational and economic meaning of Marine Pollution Prevention Law (MPPL) of North Korea was studied with review and comparison of North Korea's environmental legislation system. North Korea's MPPL is the basic legislation system against pollution activities. This law has the purpose of gaining of marine environmental protection and resources and declares mainly the marine environmental protection with little definition of action plan and means. To analyze economic achievements of MPPL, more macro- and microeconomic data of North Korea should be accumulated. However, environmental issues are relatively effective to discuss common goal of environmental protection and economical cooperation between Korea and North Korea. To prepare reunification, understanding of North Korea's MPPL is the first step for collaboration of marine environmental conservation.

Purpose: We investigated the satisfaction of physical therapy course according to teaching ways after COVID-19. Methods: 336 students in major of physical therapy were recruited in this study. Based on the classification of subjects in the national examination, the questionnaire was divided into 6 subjects in the basic field of physical therapy, 2 subjects in the field of physical therapy diagnostic evaluation, 8 subjects in the field of physical therapy intervention, and 3 subjects in other fields. The Likert scale was used. Results: In the basic field of physical therapy, all subjects were shown the high score of the satisfactory in face-to-face classes except for the public health and medical law compared to the non-face-to-face classes and mixed classes. Regarding the field of physical therapy diagnostic evaluation, the principle of diagnostic evaluation was shown the high score of the satisfactory in face-to-face classes compared to the non-face-to-face classes and mixed classes. In the field of physical therapy intervention, all subjects were shown the high score of the satisfactory in face-to-face classes compared to the non-face-to-face classes and mixed classes. Conclusion: We found that the face-to-face classes in most of subjects was shown the high score of satisfactory. We believed that our results can be used as basic data for physical therapy major learning methods.

Objectives : According to the data from the 2016 Yearbook of Traditional Korean Medicine, 10 out of 12 medical schools of Korean medicine are offering medical ethics. Medical ethics has become essential in Korean medicine education, but there has been no agreement on the content of education yet, so initial discussions are necessary with respect to the content and methods of education. Methods : In this study, basic data were collected by searching papers, reports, books, and media articles on medical ethics related to Korean medicine education, and by studying the website of medical schools of Korean medicine nationwide. Based on the collected data, the status of medical ethics lectures were determined and compared with the current state of medical ethics lectures by western medical schools. The contents suitable for medical ethics education at medical schools of Korean medicine were discussed. Results : The topics of the medical ethics include: the basic concepts of medical ethics, the ethics of birth, the ethics associated with genetics, the ethics associated with death, and the ethics regarding doctor-patient interaction, the ethics of medical research, medical rationing ethics, ethics between medical staffs, medical law and ethics, philosophical base of medical ethics, ethics of doctor as professional, and moral personality formation of doctor. The contents of medical ethics in traditional Korean medicine reflected views on the human body and life based on "Huangdi's Internal Classic"and medical ethics from the viewpoints of Buddhism and Confucianism. Conclusions : Medical schools of Korean medicine are medical training institutions, and medical ethics education is essential to become a Korean medicine doctor as professional worker, medical practitioner, and biomedical researcher. There is no fundamental difference in the basic principles of medical ethics in both western and Korean medicine, and there are differences in contents depending on the clinical practice. The contents of medical ethics on clinical practice should be modified for Korean medicine doctors, and traditional Korean medicine ethics would be set up upon that. In the national licensing examination, medical ethics needs to be added as one part so that all the ethical problems related to the clinical situation can be solved.

According to the Marine Traffic Safety Law, revised in 2009, Marine Traffic Safety Audit is introduced to secure the safe navigation, to prevent the marine accident and to maximize the efficiency of the port. In this audit system, marine traffic safety assessment is the most important scheme because the primary purpose of the audit system is to identify potential risk elements affecting safe navigation. Even though the reliability of audit result depends on the selection of assessment models, there are no independent assessment models for Korean coastal waters and most of models used in Korea currently are developed by foreign countries. Therefore, the development of the independent assessment model for Korean coastal water is required. This study, prior to the development of independent assessment model, aims to provide a basic data by comparing two foreign assessment models in Ulsan port area with marine accident statistics data.

After investigating the basic problems of seepage flow, the friction factor equation of power form was developed for solving them. The use of power law for the estimation on friction factor enabled to develop the explicit form of equations without any iteration process being related to various non-dimensional physical numbers. For the derivation of friction factor equations, the existing data were re-analyzed, and the simple method of seepage flow design was devised with the power law equations for the estimation of slope, discharge, and diameter.

Purpose - This article accentuates that there is pervasive corruption in the supply chain and procurement of goods and services in the South African public sector, particularly in the local sphere of government. Consequently, the poor and the indigents who are supposed to receive quality services are affected. Therefore, the article emphasizes the need to strengthen compliance in the supply chain and procurement processes in order to combat corruption. Research design, data, and methodology - This article extensively utilized qualitative literature review approach to address and solve the problem of endemic corruption in the supply chain and procurement being perpetrated by local government officials. Results - The synthesis shows that by strengthening compliance of supply chain and procurement strategies, measures and frameworks, the likelihood of corruption will be drastically reduced if not totally eradicated. It demonstrates that the poor and the indigents who are supposed to receive quality services are being denied due to corruption. It also shows that failure to comply should result to enforcement of punitive sanctions against perpetrators. Conclusions - This study indicates that effective and efficient implementation of supply chain and procurement strategies, measures and frameworks are panacea for curbing corruption in South Africa public sector especially at the local sphere of government.

Change requests occur persistently in the construction phase of a construction project. The law requires that the contract amount be adjusted in accordance with the relevant regulations when there is a change in the construction amount due to the design change in the construction contract. SAVE international, on the other hand, defines the value methodology as a systematic and structured approach to improving projects, products and processes. Design Changes in the construction projects require organizational efforts to improve value and quality. However, the law does not include change requests in which the VE object is fixed and related data is collected and function analysis can be derived in a short time. Therefore, it is necessary to apply VE to the design change procedure, which can further improve the value of construction work. The application derived from this study need to be presented as simply as possible without compromising the basic concept of VE. If the application is extended to the field and proved to be effective, it is expected to contribute to the overall value of construction work.
