Objectives The purpose of this study is to compare the effects between the KL-Grade and improvement of knee pain treated by Korean Medicine therapy. Methods 114 patients who received inpatient treatment from July 2014 to May 2017 in the Daejeon Jaseng of Korean Medicine Hospital were divided into 5 groups by the KL-Grade. All patients received a combination of treatment including acupunture, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows. Results After treatment, KL-Grade 0 group's Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) improvement was $2.02{\pm}1.69$, $7.50{\pm}9.67$ and $0.11{\pm}0.15$ respectively. KL-Grade 1 group's improvement was $2.09{\pm}1.23$, $11.75{\pm}13.99$ and $0.12{\pm}0.13$ respectively. KL-Grade 2 group's improvement was $1.60{\pm}1.07$ and $14.70{\pm}14.19$ respectively. But In this group, EQ-5D Index has decreased by $0.01{\pm}0.10$. KL-Grade 3 group's improvement was $1.88{\pm}1.31$, $7.81{\pm}13.35$ and $0.13{\pm}0.20$ respectively (p<0.034). In the case of KL-Grade 4, the population was not statistically significant (N=2) and therefore excluded from statistical significance. And there was no statistically significance between 4 group's improvement after treatment (p>0.05). Conclusions The above study showed that Korean medicine treatments showed significant therapeutic effects on knee pain and degenerative knee joints, but there was no significant difference in the effectiveness of degenerative arthritis (KL-Grade).

집게손가락과 반지손가락의 길이비(2D:4D)는 모체 내에서 태아의 테스토스테론과 에스트로겐의 영향 수준을 반영한다. 본 연구는 보건의료 대학생의 2D:4D와 성역할 정체감 유형을 파악하고 2D:4D와 성역할 정체감 사이의 관계를 파악하고자 시도되었다. 연구대상자는 보건의료 대학생 266명(남자 120명, 여자 146명)으로 성역할 정체감 설문(KSRI)에 응답한 후 복사기를 이용하여 손가락길이가 측정되었다. 연구 결과, 보건의료 대학생들의 2D:4D는 남자 0.95, 여자 0.96으로 남녀 간에 유의한 차이가 있었으며(p<0.01), 성역할 정체감에 있어서는 남자는 양성성 유형(38.3%)이, 여자는 미분화 유형(35.6%)이 가장 많았다. 남녀사이에 남성성 점수는 유의한 차이가 있었으나(p<0.001), 여성성 점수는 유의한 차이가 없었고, 성역할 정체감 유형에 따라서는 2D:4D에 차이가 없었다. 또한 남성성 여성성 점수에 따른 성역할 정체감과 2D:4D 사이의 상관관계는 남자에서는 왼손의 손가락 길이비가 낮을수록 남성성 점수가 높았으며(r= -0.188, p<0.05), 여자에서는 유의한 상관관계가 없었다. 결론적으로 보건의료 대학생 중에서도 여학생들에게 상황적인 변화에 더 잘 적응할 수 있도록 양성성 유형으로 나아갈 수 있는 중재 프로그램이 더욱 더 필요하다. 또한 본 연구에서는 2D:4D와 성역할 정체감과의 상관관계가 높게 나타나지는 않아 추후 한국인을 대상으로 한 더 많은 연구가 필요할 것으로 사료된다.

목 적: 방사선치료계획에 있어서 정상조직과 치료부위의 선량 분포는 매우 중요하다. 이에 본원에서는 유방암 환자를 대상으로 Three-dimensional conformal radiation therapy (3D-CRT), Helical tomotherapy (TOMO)의 방법으로 방사선치료계획을 세웠으며 이에 선량분포를 분석하여 실제 임상에서의 적용여부를 알아보고자 한다. 대상 및 방법: 20명의(좌측: 10명, 우측: 10명) 유방보존절제술 환자를 대상으로 시행하였으며 방법으로는 같은 조건에서 3D-CRT는 Philips사의 Pinnacle을, TOMO는 TomoTherapy사의 TOMO Planning System을 이용해 치료계획을 세웠다. Dose-Volume Histogram (DVH)의 prescribed dose (PD)에 대한 PTV의 Homogeneity index (HI)와 Conformity index (CI)를 구하였고, 정상조직의 dose- volume 관계를 비교하였다. 결 과: Homogeneity index (HI)와 Conformity, index (CI)는 TOMO에서 우수한 결과를 나타났다. $V_{-50-IB-NPTV}$ (the percentage ipsilateral non-PTV breast volume that was delivered 50% of the prescribed dose)는 3D-CRT: 40.4%, TOMO: 18.3%, $V_{20-IL}$ (the average ipsilateral lung volume percentage receiving 20% of the prescribed dose)는 3D-CRT: 4.8%, TOMO: 14.2%, $V_{20-10H}$ (the average heart volume percentage delivered 20% and 10% of the prescribed dose in left breast cancer)는 3D-CRT: 1.6%, 3% TOMO: 9.7%, 26.3%의 결과를 보여준다. 결 론: 유방암 환자의 방사선치료계획 방법들은 PTV에서 원하는 선량분포를 보여줬다. 그러나 TOMO는 좋은 Homogeneity index (HI), Conformity index (CI)와 Breast를 보호하는 장점이 있는 반면에 Lung과 Heart에서는 많은 피폭선량이 있음을 알 수 있기에 TOMO의 방사선치료계획시 주의해야 할 점으로 사료된다.

본 논문에서는 국방 R&D기술 평가에 적용 가능한 기술등급평가 방법론을 제시하였다. 국방 R&D기술 등급평가를 위해서 첫째, 다중회귀분석을 활용한 기술료수입 예측 모델을 설계하여 기술수익지수가 도출되도록 하였다. 모델을 통해 예측된 기술료수입이 커질수록 기술수익지수도 커진다. 둘째, 계층분석방법을 이용하여 기술에 대한 전문가 의견을 다각적으로 반영하는 기술력평가지수가 산출되도록 하였다. 기술력평가지수 평가항목 개발을 위해 델파이기법을 사용하여 전문가 의견을 종합하였고, 요인분석 및 AHP를 사용하여 평가항목을 구조화하였다. 마지막으로 기술수익지수와 기술력평가지수의 가중평균의 크기에 따라 적절한 기술 등급이 도출되도록 하였다. 각 지수별 가중치는 전문가 의견을 종합하여 설정하였다. 본 연구를 통해 개발된 국방 R&D기술 등급평가 방법론은 국방기술을 등급으로 평가가능하게 한 최초의 방법론이다. 다른 분야와 마찬가지로 국방 분야에서도 기술의 연구개발 초기단계에는 불확실성이 크기 때문에 화폐단위로 표시되는 가치평가결과의 정확성이 매우 떨어진다. 따라서 특히 실무적인 관점에서 볼 때 R&D기술 부문에서는 기술등급평가 기법이 긴요할 것으로 판단된다. 본 방법론을 실무에 적용하게 되면, 국방 연구개발 관련 정책담당자에게 과학적이고 정량적인 기술의 가치 판단 기준을 제공하여 효율적인 R&D예산 배분에 기여할 수 있으며, 국방 R&D분야의 기술이전 활성화 업무에도 활용할 수 있을 것이라 판단된다.

This study was intended to assess the effects of low glycemic index (LGI) nutrition education on dietary management and glycemic control of patients with type 2 diabetes mellitus. The subjects were 48 sex-matched patients with type 2 diabetes mellitus, aged $66.5\;{\pm}\;6.2$ years, visiting a public health center. They were divided into two groups: the control group (males 10, females 14) and the educated group (males 10, females 14). The educated group was provided with a LGI nutrition education program for 7 weeks. The control group was educated only one time for general diabetic education. Anthropometric indices, knowledge and perception of efficacy of low glycemic index carbohydrates, dietary glycemic index (DGI) and glycemic load (DGL), fasting blood glucose, and HbA1c were assessed. In the educated group body weight, body mass index and systolic blood pressure (from $138.0\;{\pm}\;18.9\;mmHg$ to $130.6\;{\pm}\;15.0\;mmHg$) were significantly reduced after the nutrition education (p < 0.05). The scores of knowledge and perception of efficacy of low glycemic index carbohydrates increased significantly in the educated group. Dietary glycemic index and glycemic load of the educated group decreased significantly from $103.4\;{\pm}\;67.6$ to $45.4\;{\pm}\;27.1$ (p < 0.001), and from $173.3\;{\pm}\;135.9$ to $66.8\;{\pm}\;50.4$ (p < 0.001), respectively. Also fasting blood glucose and HbA1c levels of the educated group significantly decreased from $124.5\;{\pm}\;28.8\;mg/dL$ to $96.7\;{\pm}\;21.6\;mg/dL$ (p < 0.001) and from $7.1\;{\pm}\;1.3%$ to $6.4\;{\pm}\;1.2%$ (p < 0.05), respectively. The score of knowledge and perception of efficacy of low glycemic index significantly correlated with fasting blood glucose and HbA1c levels negatively. DGI, DGL and duration of diabetes significantly correlated with HbA1c level positively. From stepwise multiple linear regression analysis, DGI, DGL and the duration of diabetes were extracted as factors influencing HbA1c level of the subjects. The results of this study suggest that low glycemic index nutrition education programs is an effective intervention measure for the glycemic control in type 2 diabetic patients.

In order to determine if a relationship exists between the clinical symptoms of TMJ dysfunction and the reproducibility of mandibular movements, twenty one subjects were chosen. The control group consisted of 5 subjects who were determined to be free from signs and symptoms of dysfunction . The sixteen experimental subjects were selected on the basis of their having dysfunctional symptoms. The author obtained two sets of pantographic tracings. Each set consisted of tracings from three both lateral and one protrusive movements. A second set of tracings were recorded immediately on the new recording papers using the same procedure as the first tracing. The tracings were scored by Pantographic reproducibility index (PRI). The obtained results were as follows. 1. Mean PRI scores of groups increased as the degree of dysfunction were increased. 2. For the groups of no or slight dysfunctional symptoms the PRI scores of the second tracing were smaller than the first one, wherea the scores of the second tracing from $D_2,\;D_3$ group were larger than the first tracing. 3. Differences between the mean PRI scores of control group and those of experimental group were statistically significant. 4. The second sets of tracings were more reliable statistically than those of first ones. 5. PRI can be used as a meaningful aid for the evaluation of the diagnostic and therapeutic results of treatment modalities for the TMJ dysfunction. 6. At 3east two sets of tracings should be recorded when the PRI is to be used to detect the incoordinated movements of TMJ dysfunction patient. 7. PRI scores of control group ($D_0$) was 137.7, thus, mandibular movement was reproducible, whereas PRI scores of experimental groups ($D_1,\;D_2,\;D_3$) were 22.5, 27.7, 30.45 respectively, thus were nonreproducible.
