  • Type I, II, III are regarded as "true" joint receptors, type IV is considered a class of pain receptor. Type I, II and III mechanoreceptors, via static and dynamic input, signal joint position, intraarticular pressure changes, and the direction, amplitude, and velocity of joint movements. Type I mechanoreceptor subserve both static and dynamic physiologic functions. Type I are found primarily in the stratum fibrosum of the joint capsule and ligaments. Type I receptors have a low threshold for activation and are allow to adapt to changes altering their firing frequency. Type II receptors have a low threshold for activation. These dynamic receptors respond to joint movement. Type II receptors are thus termed rapidly adapting. Type II joint receptors are located at the junction of the synovial membrane and fibrosum of the joint capsule and intraarticular and extraarticular fat pads. Type III receptors have been found in collateral ligaments of the joints of the extremities. Morphologically similar to Golgi tendon organ. These dynamic receptors have a high threshold to stimulation and are slowly adating. Type IV receptors possess free nerve ending that have been found in joint capsule and fat pads. They are not normally active, but respond to extreme mechanical deformation of the joint as well as to direct chemical or mechanical irritation. Small amplitude oscillatory and distraction movements(joint mobilization) techniques are used to stimulate the mechanoreceptors that may inhibit the transmission of nociceptors stimuli at the spinal cord or brain stem levels.

  • The purpose of this study is to guide efficient ways to teach cultural aspects in Korean elementary English education through analyzing many studies on elementary English culture education. In global era, English education must be performed based on understanding of other various cultures for authentic communication. However, Korean elementary students have difficulty to approach or to be exposed to the culture of English speaking countries. Elementary English culture education is neither well organized nor performed for some reasons. The reasons are as follows. Frist, English teachers are not confident with the culture and they consider themselves not having enough experiences and knowledge to teach. They were not taught cultural aspects and the cultural aspects were not emphasized. Second, there are not appropriate culture related teaching materials in the textbooks and teachers' guide books. Therefore, necessary cultural aspects should be selected by English education experts and provided in the textbooks and teachers' guide books. Those two books should be systematically connected. Elementary English teachers should have more opportunities to understand and experience other various cultures. Language is a part of culture and culture is a part of language. Acquiring the second language is acquiring its culture. The culture education for authentic communication is accomplished from managing cultural aspects in textbooks and cultivating English teachers with experience and understanding of target culture.

  • On the subjects of elementary 3rd grade three child prodigies who had learned the four fundamental arithmetic operations and primary concepts of fraction, this study conducted a qualitative case research to examine how they composed schema of addition and multiplication of fractions and transformed schema through recognition of precise concepts and linking of concepts with addition and multiplication of fractions as the contents. That is to say, this study investigates what schema and transformed schema child prodigies form through composition of primary mathematic concepts to succeed in relational understanding of addition and multiplication of fractions, how they use their own formed schema and transformed schema for themselves to approach solutions to problems with addition and multiplication of fractions, and how the subjects' concept formation and schema in their problem solving competence proceed to carry out transformations. As a result, we can tell that precise recognition of primary concepts, schema, and transformed schema work as crucial factors when addition of fractions is associated with multiplication of fractions, and then that the schema and transformed schema that result from the connection among primary mathematic concepts and the precise recognition of the primary concepts play more important roles than any other factors in creative problem solving with respect to addition and multiplication of fractions.

  • "Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows; 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview, physical measurement, observation were used in 22.8%, 8.2%, 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

  • Medical practices such as surgery often need to accompany anesthesia, which frequently causes medical accidents. In order to determine whether a medical accident related to anesthesia was caused by a doctor's fault, it is necessary to understand what is the duty of care required for the medical staff such as a doctor through all stages of anesthesia. This paper analyzed Supreme Court decisions since 1990s and recent lower courts' decisions in order to understand standard of care with respect to anesthesia. While numerous medical accidents were related to inhalation anesthesia in the past, it turned out that recent medical accidents were often related to the use of intravenous or local anesthetics. In particular, legal disputes with respect to medical accidents related to propofol have considerably increased since 2007. However, because Supreme Court decisions as to anesthesia accidents are mostly related to inhalation anesthesia, they seem to be insufficient to set standard of care as to other types of anesthesia accidents. In light of the fact that medical accidents related to the use of propofol have been increasing, it is critical to establish and maintain clinical guidelines on the use of each anesthetic in the medical field. However, The Courts can present the standard of care suitable for medical reality to serve as a compass for medical practices.

  • Patients diagnosed with the serious disease of cancer may have anxiety and fear of closed spaces while receiving radiation therapy. This study investigated patients receiving treatment based on Linac and Tomotherapy to look into this anxiety and fear. Study method was survey. The survey was performed according to treatment duration (treatment within 5 minutes, 10 minutes, over 20 minutes, and over 30 minutes). The patients were also surveyed about any experience of changing treatment rooms or machines due to machine failure. A total of 200 survey questionnaires with full answers were researched in this study. As a result, it was found that the less the patients' experience on radiation therapy, the higher their anxiety was. The dominating reason for this result was because the patients expected possible pain during the treatment process. In terms of treatment machine, Linac showed the highest anxiety of all for the openness of its patient stand. The most stable status was found in the case of treatment between 20 minutes and 30 minutes using Tomotherapy. The reason was the coziness of Tomotherapy machine. In the case of receiving the treatment for over 30 minutes, patients felt anxious for the isolation from the outside. The study findings are expected to serve as the necessary data for quality medical service with enhanced patient satisfaction in the clinical field.

  • The purpose of this study is to analyze precedents related with child abuse for protection of the rights of the child. There should be the law related with 'punishment for child abuse,' which is the grounds of punishment, to make a precedent in the law punishing for 'child abuse,' but there is the concept only for 'child abuse' in the Child Welfare Law, the fundamental law; therefore, for a direct judgment for punishment, only precedents of 'child abuse' related with loss of parental rights and judgements for criminal cases, civil cases and laws covering special cases have been made. For that reason, 'the special law related with punishment for child abuse cases' is desperately required (On last December 23, 2013, the special law related with punishment for child abuse cases passed the National Assembly). Hence, precedent analysis had performed by grouping precedent from 2000 to 2013 which were not judged as child abuse in trial but can be regarded as child abuse. When analyzing each precedent according to the contents of analysis and judgment by fact relevance in this study, problems which the current legislative system has were deducted through an implication of each case by diagnosing using diagraming after classifying lower instance terminated cases, which precedents of the Supreme Court and judgments sent to the Supreme Court were excluded, while excluding cases settled in the civil level and classifying analysis of civil case precedents which did not become a criminal case and completed as a civil case, analysis of criminal case precedents, classification of precedents of loss of the parental rights (regarding child abuse) and precedents of any other special laws. And compensatory tasks for special laws regarding punishment of child abuse were presented while suggesting compensatory tasks for the legislation regarding deducted problems.
