Objective: The purpose of this study was to investigate the effects of aqua-noodles on the practice of underwater walking in patients with hemiplegia. Method: After an oral explanation and signing an IRB approved consent form 10 participants ($66.8{\pm}10.75yr$, $165.3{\pm}8.79cm$, $73.6{\pm}46kg$) agreed to participate in this study. Each of the participants was required to walk with the aqua noodles and without the aqua-noodles in a swimming pool. Each participant was asked to walk a distance of 5 m a total of 10 times, 5 with and 5 without the aqua-noodles. The depth of the swimming pool was at 1.3 m, approximately chest height. The following variables were calculated for analysis; height of the knee (m), knee joint ROM ($^{\circ}$), ankle joint ROM ($^{\circ}$), knee joint maximum angular velocity ($^{\circ}/sec$), and ankle joint maximum angular velocity ($^{\circ}/sec$). Results: First, there was a significant increase in time (s) for the maximum knee height to reach as well as the maximum knee height (m) increased when the participant used the aqua-noodles. Second, there was a statistically significant decrease in stride length when the aqua-noodles were used. Conclusion: This study helps to verify that the effect of underwater walking exercise can provide a suitable walking exercise environment. The results of this study provide systematic scientific information about how walking in water can be used for the rehabilitation of patients and the elderly.

Objectives: The purpose of this study is to collect and analyze the KCD codes applied to the treatment of 27 postpartum women who had been treated with Korean traditional medicine in a Korean medicine hospital, so that this study may be used as a basic data for setting the direction of postpartum Korean medical treatment research. Methods: It was approved by the Institutional Review Board (IRB) of ${\bigcirc}{\bigcirc}$ University medical center (IRB approval number : WSOH IRB H1708-02-01). Twenty-seven postpartum women who had been treated at ${\bigcirc}{\bigcirc}$ University medical center were received outpatient treatment for two weeks (from September 27, 2017 to January 5, 2018), and the KCD codes applied to the mothers were collected after obtaining the consent. On the day of registration of the study, the fertility, obstetric history and high-risk pregnancies were identified through an interview. Results: 1. The mean age of the 27 subjects was $33.33{\pm}3.99\;years$ old. Among the subjects, 17 mothers (63.0%) were high-risk pregnancy and 10 mothers (37.0%) were normal. 2. Among the 22 major disease categories, 8 categories were used. M code (musculoskeletal system) was used 243 times (70.85%), followed by R code (unclassified symptom) of 51 times (14.87%) and U code (special purpose code) of 23 times (6.71%). 3. The most commonly used code among the ten frequently used codes was M25.57 (joint pain, ankle and foot), a total of 47 times. Of the remaining nine codes, except for R60.1 (systemic edema) and U68.4 (The deficiency of yang in Bi), all codes were M codes (musculoskeletal system). 4. The M code (musculoskeletal system) was the most used major disease category in high-risk group, a total of 159 times. But in specific categories, the most commonly used code was R60.1 (systemic edema), a total of 28 times. 5. In normal group, the M code (musculoskeletal system) was the most used major disease category, a total of 84 times. Also, in specific categories, the most commonly used code was M25.57 (joint pain, ankle and foot), total 29 times. 6. The U code, corresponding to 'the diagnosis of childbirth and other obstetrical medical use', was used 23 times (6.71%), O code three times (0.87%) and Z code two times (0.58%), which was less than 10% of the total number of codes used. Conclusion: When analyzing KCD codes related to Korean medicine treatment for postpartum diseases, it is important to select the KCD codes that reflect the actual clinical state.

Purpose: To identify research trends in the Journal of Muscle and Joint Health. Methods: In total, 315 studies published between 2008 and 2020 in the Journal of Muscle and Joint Health were reviewed using analysis criteria developed by the authors Results: Most participants were adults or older adults, they mostly had arthritis. The types of research design were descriptive research (46.4%), quasi-experimental design (21.9%), randomized controlled trial (1.9%), and qualitative research (4.1%). The occupation of most authors was professor in universities (61.0%). Data were collected mostly in hospitals (41.6%) or communities (24.4%) using a questionnaire (52.4%). Written consent was obtained at 75.6% and 47.9% of studies were approved by the Institutional Review Board (IRB). The instruments measuring physical concepts such as pain, flexibility, sense of balance and fatigue were mostly used. The most common interventions in experimental studies were physical interventions, with the main being exercise. Key words were categorized into four nursing meta-paradigms: human, health, environment and nursing. The most frequently reported key words were included in the health domain. The most frequently used key words were physical intervention, older patient, osteoarthritis, pain and depression. Conclusion: The results suggest that more research studies targeting various age groups related to muscle and joint health are required. Additionally there is a need to increase the number of qualitative studies, randomized experimental studies, and systematic review studies. It is necessary to pay attention to compliance with research ethics publication regulations.

Objective: The purpose of this study was to reduce the burden on dental hygienists in performing dental hygiene processes in the clinic. This study systematically analyzed dental hygiene problems and dental hygiene planning according to the oral condition of patients by applying an oral health care program based on the dental hygiene process. Methods: This study analyzed influential factors of 17 dental hygiene problems and 12 dental hygiene plans according to the oral health index and charts of 185 patients. This study was approved by the Institutional Review Board (IRB No. 1041449-201801-HR-003) of Silla University. The frequency of dental hygiene problems and dental hygiene planning was analyzed and correlations among the oral health index, dental hygiene problems, and dental hygiene planning were analyzed. Results: The higher the bleeding on probing score was, the more scaling was planned. The higher the calculus rate was, the more air-jet and jaw joint disorder prevention education was planned. The higher the O'Leary index was, the more dietary education and air-jet was planned. The higher the Simplified Oral Hygiene Index was, the more air-jet and jaw joint disorder prevention education was planned. The higher the Periodontal Screening and Recording index was, the more scaling and professional tooth cleaning was planned (p<0.05). Conclusions: The burden of oral preventive duties on dental hygienists will be minimized by systematically establishing problems and planning of dental hygiene according to patients' oral health index scores. Therefore, it is expected that dental hygienist can actively use the dental hygiene process in oral health care programs.

Objectives This study was aimed to validate Sasang Constitution Questionnaire for Japanese (SSCQ-J). Methods Sasang Constitution Questionnaire for Patients (SSCQ-P) was developed by joint researches between the Society of Sasang Constitutional Medicine and Korea Institute of Oriental Medicine. We translated SSCQ-P into Japanese and modified some items of that for Japanese. By getting approval from the Institutional Review Board（IRB）of School of Medicine, Keio University, we conducted a questionnaire survey of patients who visited Oriental Medicine Center from early January until mid-February 2011. The total of 364 patients filled out that Questionnaire and gave an interview with a Sasang constitution specialist. Using this Questionnaire data, we made Sasang constitutional classification functions and calculated diagnostic accuracy rate of SSCQ-J using discrimination analysis. Results 1. Male group's diagnostic accuracy rate of SSCQ-J was 77.01% and female was 78.10%. 2. Diagnostic accuracy of SSCQ-J was a little higher than SSCQ-P Conclusions 1. SSCQ-J can be considered to have good discriminant power compared with SSCQ-P 2. Further research with SSCQ-J will be helpful in the comparison study on the usual symptoms between Korean and Japanese as well as development of good discriminant function.

목적: 직접 자기공명 견관절 조영술에서 측정한 상부 관절순의 크기와 상부 관절순 전후방 파열과의 관계를 평가하고자 함. 대상과 방법: 만성적인 견관절 통증 또는 불안정성으로 직접 자기공명 견관절 조영술을 시행하고 견관절 관절경 수술을 받은 296명의 환자 (300개의 견관절) 이 연구 대상이 되었다. 모든 환자에서 관절경 수술 기록이 검토되었으며 자기공명영상이 두 명의 영상의학과 의사에 의해 분석되었다. 상부 관절순은 T1 강조 관상면 영상에서 상완 이두근 장두가 사라지고 상부 관절순이 가장 커보이는 단면에서 측정되었다. 역삼각형 모양의 상부 관절순에 대하여 밑변과 높이가 측정되었고 관절경 수술 상에서 상부 관절순 전후방 파열을 가진 군과 그렇지 않은 군 사이에 통계적으로 유의한 차이가 있는지 비교하였다. 결과: 17명의 환자는 낮은 영상의 질 때문에 연구에서 제외되었고 총 279명의 환자 (283개의 견관절) 중 122명(43.1%)의 환자에서 상부 관절순 전후방 파열이 있었고 161명 (56.9%)의 환자에서는 없었다. T1 강조 관상면 영상에서 측정된 상부 관절순의 밑변/높이의 평균값은 상부 관절순 전후방 파열을 가진 군과 안 가진 군에서 측정자 1의 경우 8.8 mm / 5.2 mm, 8.5 mm / 4.9 mm 였고 측정자 2의 경우 8.2 mm / 4.9 mm, 8.1 mm / 4.5 mm 그리고 8.0 mm / 4.8 mm, 7.6 mm / 4.3 mm 였다. 상부 관절순 전후방 파열 환자군에서 상부 관절순 높이의 평균이 그렇지 않은 군보다 통계적으로 유의하게 컸다. 결론: 직접 자기공명 견관절 조영술 T1 강조 관상면 영상에서 측정한 상부 관절순의 높이는 상부 관절순 전후방 파열 환자군에서 그렇지 않은 군보다 통계적으로 유의하게 컸으며 이것은 상부 관절순이 관절와를 많이 덮는 경우 상부 관절순 전후방 파열의 소인이 될 가능성을 제시한다.
