The purpose of this study was to compare Korean and Japanese female college students' body sizes, their perceptions about body size, and body satisfaction based on similar cultural background. Subjects consisted of 185 Korean students and 91 Japanese students from October to December, 2000. The age range was 18 to 28 years. We measured body sizes of subjects directly and examined by questionnaire the degree of body cathexis, perceived body size, ideal body size. The results were as followed. 1) Korean women had slimmer silhouette with longer arm and longer leg than Japanese, while Japanese women had more voluminous silhouette with smaller waist circumstance and bigger hip circumstance than Korean. 2) There were not differences between perception about each body size of the Korean women and Japanese women, except arm length. Especially, two groups felt themselves as greater on thigh. 3) There were not differences between satisfaction about body of Korean women and Japanese women, except height. Generally, two groups had lower body satisfaction on each body area, especially on thigh, lower body part, abdomen, hip, and weight. 4) Perception of body size had higher correlation with body satisfaction than actual body size. Lower satisfaction was related to more negative perception of body size. 5) Regarding ideal body size, Korean women pursued bigger height, weight, waist, and hip than Japanese. However, Japanese women pursued bigger bust than Korean. This means that Japanese women pursued more voluminous body silhouette.
The purposes of this study were to investigate the relationships between the degree of physical pain and the knowledge and preventive actions of musculoskeletal diseases among dental hygiene students with a potential risk of contracting those diseases and thus to help them prevent them. A survey was taken among 207 sophomores and juniors specializing in dental hygiene at S1 and S2, Gyeonggi Province in the area of physical pain, knowledge of musculoskeletal diseases, and preventive actions against them. The findings were as follows: 1. The mean scores of the sophomore in the knowledge of musculoskeletal diseases were $6.20{\pm}2.21$, and those of the juniors were $6.72{\pm}2.29$. The mean scores of the sophomores and juniors in the preventive actions against musculoskeletal diseases were $22.50{\pm}2.37$ and $22.29{\pm}3.01$, respectively. 2. The subjects displayed severe physical pain in the lower back, shoulder, and neck in the descending order and medium physical pain in the neck, shoulder, and lower back in the descending order. 3. The higher level knowledge of musculoskeletal diseases they had, the less physical pain they felt. And there were significant differences among the shoulder, lower back, hip, ankle, and foot. 4. There were relationships between physical pain and the preventive actions against musculoskeletal diseases in "placing the hands at the height of the elbows during treatment", "reducing such positions as bending and extending during treatment", "narrowing the distance with the patient", "taking regular breaks during treatment for recovery", "trying not to incline the neck, back, arm, and wrist as much as possible", and "trying to keep the torso in the neutral position." 5. As for the education about musculoskeletal diseases, 74 sophomores(88.10%) and 102 juniors(89.74%) answered they received no such education. The results suggest that there should be some instructions to help dental hygiene students practice the preventive actions against musculoskeletal diseases and further prevention programs against those diseases.
The goal of mathematics education in the 7-th national curriculum is focused on maximizing learning effectiveness through teaching mathematics, considering learning contents and levels appropriate to various levels of students' abilities. Thus, reduction of contents, learner-centered way of teaching, and multi-step differentiated learning are centered around the curriculum. However, in reality one of the most difficult problems mentioned by many inservice teachers is that students are not interested in school mathematics because some of them tended to learn mathematics in advance in private institutes and others felt difficult from school mathematics. Thus, alternative solutions are strongly required. When students are more interested in mathematics classes and instructional materials, as a more effective way of teaching, are appropriately used, problems mentioned above are expected to be solved. In order to solve problems, additionally, this study investigated the amount of time assigned to each area of mathematics textbooks from level 1-A to level 6-B, which are currently used in elementary school. This study also examined inservice teachers' views about how instructional materials should be used. This will be helpful on using and developing instructional materials, and it will lead to more exciting classes of mathematics. However, these teaching materials need to be carefully used regarding their relationships with pedagogical transfer, metacognitive movement, and localization.
Objectives: This study aimed to investigate the experiences and awareness of Korean Medicine professors towards research ethics issues and curriculum development. Methods: Electronic mails for requesting the survey participation were sent to 531 professors who were listed in the DB of Association of Korean Medicine. Professors who agreed to participate in the survey were connected to the self-administered questionnaire site, and the responses were stored in real time. Professors were asked the experience of research misconduct cases, the necessity, contents and evaluation method of research ethics education, etc. ANOVA was performed to test the differences of ethics education effects among sub-groups of respondents. Results: Of 137 professors who opened the e-mail, 127 completed the questionnaire. Most professors (87.4%) reported to witness the research misconduct cases, and felt the necessity of research ethics education for professors as well as students. 31.4% of respondents preferred the practice-focused course, and 43.3% preferred the PASS/FAIL basis evaluation system. Professors with shorter education career and professors majoring basic Korean Medicine expected higher effect of ethics education than others. For detailed items of research ethics education, 'ethical writing' and 'ensuring research integrity' were prioritized in the aspects of both personal ethics and social demand. Conclusions: In this study, detailed matters of research ethics education in Korean Medicine area were drawn. Further study and policy development are needed to facilitate the introduction of formal education of research ethics.

Photocatalyst reaction has limit of its usage because application range mostly centered on atmosphere purification area. Thus, it is true that an alternative plans are necessary to increase usage of $TiO_2$ as photocatalyst material. (1) The result of flow felt according to $TiO_2$ replacement rate has shown that both of anatase type and rutile type over 12% deviated from desired flow, $110{\pm}5mm$. Consequently, the range below 9% will be suitable when the anatase type $TiO_2$ if used for functional additives if workability is considered. (2) After compressive strength test, replacement rate 6-9% is estimated as suitable range if $TiO_2$ is used as compressive strength material. Rutile type and anatase type are suitable for in early-age strength and long-age strength respectively. (3) It was revealed that bending strength was dramatically decreased when replacement rate was increased. The main reason were the increase of $TiO_2$ doesn't influence hydration reaction and the decrease of bending strength. (4) The result from the water purification properties test using ion-chromatograhpy has shown that the condition with anatase type $TiO_2$ was normally better than rutile type on the same replacement rate.

This paper investigates seismic damage potential of recent September 12 M5.8 Gyeongju earthquake from diverse earthquake engineering perspectives using the accelerograms recorded at three stations near the epicenter. In time domain, strong motion durations are evaluated based on the accelerograms and compared with statistical averages of the ground motions with similar magnitude, epicentral distance and soil conditions, while Fourier analysis using FFT is performed to identify damaging frequency contents contained in the earthquake. Effective peak ground accelerations are evaluated from the calculated response spectra and compared with apparent peak ground accelerations and the design spectrum in KBC 2016. All these results are used to consistently explain the reason why most of seismic damage in the earthquake was concentrated on low-rise stiff buildings but not quite significant. In order to comparatively appraise the damage potential, the constant ductility spectrum constructed from the Gyeongju earthquake is compared with that of the well-known 1940 El Centro earthquake. Deconvolution analysis by using one accelerogram speculated to be recorded at a stiff soil site is also performed to estimate the soil profile conforming to the response spectrum characteristics. Finally, response history analysis for 39- and 61-story tall buildings is performed as a case study to explain significant building vibration felt on the upper floors of some tall buildings in Busan area during the Gyeongju earthquake. Seismic design and retrofit implications of M5.8 Gyeongju earthquake are summarized for further research efforts and improvements of relevant practice.
The purpose of this study was to determine whether the Korean Singing Voice Handicap Index (K-SVHI) was suitable for singers in other genres than vocal music to assess their vocal problems subjectively. Twenty six college students majoring in vocal music and twenty six students majoring in applied music were included in the study. They were divided into G0 and G1 in voice quality using the GRBAS scale during the tasks of singing. K-SVHI was divided into three sub-areas (Physical, Functional, and Emotional). In the singing task, both groups showed no significant difference between K-SVHI scores by G scale. In the reading task, the vocal music group had significantly higher K-SVHI in G0 than in G1 in K-SVHIs by G scale, while the applied vocal music group had significantly higher K-SVHI in G1 than in G0. Also, the two groups were not significantly different in G0, G1 in the singing task while the vocal music group showed higher K-SVHI than the applied vocal music group in G0 in the reading task. In addition, the vocal music group had higher K-SVHI than the applied vocal music group in G1 in both tasks. As comparing by groups in three sub-areas of K-SVHI, significant differences were found in the Emotional and Functional area. Those results showed that singers felt their voice problems differently by musical genres, which means that K-SVHI may not be a proper tool for evaluating voice handicap of singers in diverse voice music genres.

Anatomy: Facet joint syndrome most often affects the lower back and neck and refers to pain that occurs in the facet joints, which are the connections between the vertebrae in the spine that enable the spine to bend and twist. Many physicians have believed that the usual lesion of facet syndrome was an anatomical impairments of facet joint itself.. Facet joint injection using local anesthetics is a reliable method for the diagnosis and treatment for facet syndrome. Etiology: One of many possible causes is imbalances that can occur in stress levels, hormone levels, and nutritional levels. These imbalances can adversely affect posture, which can lead to neck and back pain. The common disorder called facet syndrome exhibits lower back pain, with or without, radiating pain to buttock and thigh due to facet joint arthropathy. Pain in the facet joint is supposedly the secondary effect of narrowing of joint space by sustained muscle contracture around joints. Syndrome: Facet joint syndrome tends to produce pain or tenderness in the lower back that increases with twisting or arching the body, as well as pain that moves to the buttocks or the back of the thighs. Other symptoms include stiffness or difficulty standing up straight or getting out of a chair. Pain can be felt in other areas such as the shoulders or mid-back area. Treatment: Non-drug treatments include hot packs, ultrasound, electrical stimulation, and therapeutic exercises. Stimulating blood flow using massage or a hot tub may also help. Alternative treatments include yoga and relaxation therapy. If your pain persists after trying these treatments, a surgical procedure called radiofrequency rhizotomy, which destroys the sensory nerves of the joint, may bring relief. Facet joint injection has been helpful in diagnosis and therapy for this facet syndrome. Radiofrequency thermocoagulation of medial branches is known to be an effective method of relieving pain caused by facet joint problems. We conclude that spasmolytic treatment of muscles connecting the two vertebral articular space would be better for treatment and diagnosis of facet syndrome rather than facet block with local anesthetic and steroid only.
The purpose of this study was to investigate oral behavior and quality of life for soldiers. Because this study basis data for the oral health education for soldiers. A total of 400 soldiers in Seoul and Gyeonggi area were surveyed and 361 data were collected. The data were analyzed by the SPSS 19.0 program. Soldiers felt that there were oral health moderated, and oral hygiene behavior was not high. Also, soldiers answer that oral health education is necessary and there was a statistically significant correlation between self rated oral health status and the need for oral health education. As the physical health, mental and social health of soldiers is related to oral health, it seems that the oral health education of soldiers should be regularly and this study can be used basic data of oral health education of soldiers.

In this paper, the proposed method is recognized the hands using color information with input image of the camera. It controls the mouse pointer using recognized hands. In addition, specific commands with the mouse pointer is designed to perform. Most users felt uncomfortable since existing interaction multimedia systems depend on a particular external input devices such as pens and mouse However, the proposed method is to compensate for these shortcomings by hand without the external input devices. In experimental methods, hand areas and backgrounds are separated using color information obtaining image from camera. And coordinates of the mouse pointer is determined using coordinates of the center of a separate hand. The mouse pointer is located in pre-filled area using these coordinates, and the robot will move and execute with the command. In experimental results, the recognition of the proposed method is more accurate but is still sensitive to the change of color of light.
