Retrostpective study of two groups of patients was conducted to evaluate the physiologic drift of the mandibular teeth following the extraction of four first premolars. The concept of physiologic drift, commonly referred to as 'driftodontics', following first premolar extractions has been gaining acceptance in the orthodontic community, the exact nature and amount of drift has not been adequately documented. There were also no guide lines as to when drift should be allowed to now. The purpose of this study was to quantify physiologic drift of the untreated mandibular dentition following extraction of the four first premolars during the early permanent and late permanent dentition stages. The early permanent dentition extraction sample(Group 1) included 26 Patients and the mean age at pretreatment was approximately 13.5 years. The observation period following extraction was approximately 6.96 months. The late permanent dentition extraction sample(Group 2) included 31 patients. The mean age at pretreatment was 21.3 years, followed by a observation period of 7.26 months. During the observation period, except for the extractions, no other mandibular therapy was rendered. Pre-and post-treatment lateral cephalograms and dental casts were analyzed. The obtained results were as follows 1. Group 2 showed marked changes in movements of the mandibular incisors and canines but minimal changes in molars. 2. The amount of changes in movements of the mandibular incisors and canines were significantly greater in Group 1 than in Group 2. The results showed no differences in rates of molar movements between groups. 3. Physiologic drift of the dentition produced desirable changes such as decreased Incisor Irregularity.

Recently, as consumers' interest and importance in health care have significantly increased, they prefer natural and organic foods that do not use chemical pesticides. Since sprout vegetables effectively promote health and prevent diseases such as cancer and cardiovascular disease, the consumption of sprout vegetables, a highly functional and safe food, has been increased significantly. This study aimed to investigate the effect of light on the growth and bioactive compounds of seven different sprout vegetables. After sowing the seeds of various sprout vegetables (kale, Chinese kale, broccoli, red cabbage, alfalfa, red radish, and radish), the sprouts were cultivated under light conditions (20℃, RGB 6:1:3, 130 μmol·m^-2·s^-1, 12 hours photoperiod) and dark condition for 7 days. Sprouts samples were taken at 1-day intervals from 4 to 7 days after treatment. The fresh weight, dry weight, plant height, total phenol content, and antioxidant capacity were measured. Brassica species (kale, Chinese kale, broccoli, red cabbage) and Medicago species (alfalfa) had significantly higher fresh weight values under dark conditions, while the content of bioactive compounds was increased considerably under light conditions. In contrast, the fresh weight of Raphanus genus (red radish, radish) significantly increased under the light condition, but the antioxidant phenolic compounds were significantly higher under the dark state. A negative correlation was observed between the growth and secondary metabolites in various sprout vegetables. This study confirmed the effect of light and dark conditions on different sprout vegetables' growth and nutritional value and emphasizes the importance of harvest time in producing high-quality sprout vegetables.

This study is to show the clinical effect of additional CP Pharmacopuncture on hypoesthesia of lower limb which was occurred by laminectomy. The patients were treated using CP Pharmacopuncture, and other treatments including acupunture, moxibustion and herbal medication. The effect of treatment was measured by Numeric Rating Scale(NRS) and American Spinal Injury Association(ASIA) scale. After treatment, NRS was gradully reduced and ASIA scale's score was incresed. These results suggest that CP Pharmacopuncture might be a possible therapeutic option for hypoesthesia of lower limb which was occurred by laminectomy.

본 연구의 목적은 산림경관의 스트레스 완화 효과를 생리측정(피부 돌출치와 심장박동시간)과 심리측정 (ZIPER 설문지)을 통하여 조사하는 것이다. 연구가설은 두 가지로 첫 번째 가설에서는 산림경관을 본 사람들의 스트레스 측정치가 인공경관을 본 사람들의 측정치보다 낮을 것이라고 예측되었다. 두 번째 가설에서는 산림경관을 본 사람들의 스트레스 해소가 인공경관을 본 사람들보다 보다 빠르고 완전하게 발생할 것으로 예측되었다. 실험에는 대학 학부학생 70명이 참여하였으며, 실험에 이용된 산림 및 인공경관은 예비설문을 거쳐 선정되었다. 실험결과를 보면 첫 번째 가설은 피부 돌출치와 긍정적인 심리요인 그리고 부정적인 심리요인에서 채택되었다. 두 번째 가설 중 스트레스 해소속도에 대한 가설은 피부 돌출치와 심장박동시간에서 모두 채택되었으나, 스트레스 해소의 완전성에 대한 가설은 피부 돌출치에서만 채택되었다. 비록 심장박동시간과 집중/호기심 요인에서 연구가설이 채택되지 못했지만 전반적으로 산림경관과 인공경관을 비교할 때 산림경관의 스트레스 완화효과가 더 크고 빠르고 완전함을 알 수 있다. 본 연구의 의의는 산림경관의 효과를 두 가지 측정(생리적, 심리적)을 이용하여 조사하였다는 점과 국외연구결과와 유사한 결과를 얻음으로써 이러한 효과가 지역에 관계없이 공통적임을 밝혔다는 점이다. 본 연구결과는 산림이 인간의 건강과 복지에 긍정적이라는 점을 입증함으로써 산림의 조성과 보존에 중요한 근거를 제공할 수 있다. 보다 발전적인 후속연구를 위해서는 다양한 종류의 인공경관과 일반시민들의 참여, 그리고 인지능력의 병행이 필요하다.

Experiment was conducted to find out the influence of nitrogen and potassium split application on the yield and physiology of rice plants in a sandy-gravel soil. Nitrogen and potassium mixed application, nitrogen split application, and potassium split application increased yield of rice by 22, 20, and 18%, respectively, compared to conventional fertilizer application. Nitrogen split application increased chlorophyll content and potassium split application increased root activity. Concentration of silica, magnesium, and calcium was increased by the mixed split application of nitrogen and potassium.

쾌적한 스포츠웨어는 기능성에 있어서 자연환경의 변화조건과 인체의 운동 및 활동에 맞추어 열절달 및 수분전달 등을 적절히 조절할 수 있어야 한다. 이에 본 연구에서는 일반환경조건 및 강우환경조건하에서의 형상기억 투습방수직물 소재의 스포츠웨어 착용에 따른 인체생리반응 및 쾌적감을 규명하기 위하여 스포츠웨어를 제작하여, 인공기후실에서 환경조건변화에 따른 온열생리학적 특성 및 주관적 감각을 측정, 그 특성을 비교, 고찰하였다. 평균피부온은 강우환경조건에서 온도가 낮게, 변동폭이 많게 나타났다. 변화경향을 운동부하를 기점으로 온도의 상승이 나타났고, 운동 2단계에 가장 높은 온도를 나타냈으며, 이후 감소하였다. 직장온은 일반환경조건에 비해 강우환경조건에서 온도의 미세한 상승을 보였다. 의복내 기후는 두 조건 모두에서 가슴부위보다 등부위의 온·습도의 변동폭이 크게 나타났고, 강우환경조건에서의 의복내 온도를 제외하고는 모두 등부위의 온·습도가 높게 나타났다. 최고 혈압은 운동의 강도에 따라 비례하여 상승하고, 최저 혈압에는 큰 영향없이 나타났으며, 변화경향은 의복내 온도의 경향과 역으로 나타났다. 평균혈압은 일반환경조건에서 6.9mmHg 높게 나타났다. 심박수는 일반환경조건에서 4.4beats/min 높게 나타났다. 강우환경조건의 주관적 감각의 평가에서, 신체에 직접 가해지는 빗물 등으로 인해 불쾌감이 증가하였고, 운동 후에는 일반환경조건과 달리 냉감이 증가하였으며, 습윤감은 최고치에 달하였다.

The education of traditional Korean medicine has been challenged for the lack of illustrated explanation of fundamental and pivotal concepts. The purpose of this study was to make suggestions for the diagrammatic concept on Qi. Thorough review was made performed to elucidate pictorial concept of Qi with medical classics and textbooks on the human physiology based on the central theories including Yin-Yang, five phase, and correspondence between nature and human. Medical terminology and its taxonomy for the Qi were examined here. We proposed more clarified terminology and related metabolic pathways for the design of schematic illustration of Qi. This study would contribute to the development of introductive drawings and educational materials fit for the apprentice.

The experiment was conducted to investigate the physiological characteristics on 16 Isolates of bacterial wilt pathogen, pseudomonas solanacearum E.F. Smith, those obtained from infected stems of tomatoes, hot-Peppers and eggplants. PSA and Sucrose medium favoured by the most of the isolates, and various degree of gelatin liquefaction occurred by each of nine isolates those alble to liquefy gelatin among 16 isolates tested. The most of the isolates except one, did not reduce methylen blue. All isolates did not utilize lactose, saccharose, and starch, although all isolates utilize the galactose. The utilization of dextrin, esculin, glucose, mannitol, raffinose and salicin was depended on each isolate.
