The purpose of this study was to examine the effects of intake of peony-licorice mixture drink on the fatigue (as evaluated by blood examination) caused by plyometric training exercise in male and female professional basketball players. Subjects consisted of male (n = 11) and female (n = 9) professional Korean basketball players. All players underwent 180 min/day (first session, 90min in the morning; second session, 90min in the evening) of plyometric training, which was performed for 6 d/wk over a period of 2 weeks with intake of peony-licorice mixture drink. Each exercise session was composed of 3 phases: warm-up for 20 min, main plyometric training for 60 min, and cool-down for 10 min. Two-way repeated analysis of variance (ANOVA) was used for statistical analysis. Interaction effects (time×group) were not observed with glucose levels for both male and female players(p>0.05). However, interaction effects(time×group) were observed with lactate levels in both male(p=0.014) and female (p=0.047) groups. It was concluded that plyometric training and intake of peony-licorice mixture drink are positive training methods and ergogenic aids, respectively, for decreasing fatigue in professional basketball players.

노후주거지 재생을 위한 주거환경개선사업의 물리적 환경정비는 인구유입 및 커뮤니티 회복에 한계를 나타냈다. 특히 자연발생적으로 형성된 필지에 시행한 획일적인 가로정비는 많은 공지를 발생시켰으며 공?폐가의 재건축을 촉진시키지 못하는 한계를 드러냈다. 본 연구는 공지 및 폐가의 텃밭활용이 물리적?사회적?경제적 재생을 포함하는 총체적 근린재생 방안으로써 노후주거지의 효과적인 재생을 도모할 수 있음에 착안하였다. 연구방법은 선행연구 분석을 통해 공지의 특성과 텃밭의 기능 및 활용성을 고찰하였으며, 현황분석을 통해 공지 및 폐가의 규모, 형상, 생성원인, 활용현황 등을 토대로 가로변형, 택지형의 유형으로 분류하고 각각의 활용방안을 모색하였다. 또한, 사업효과가 가장 큰 것으로 판단된 폐가를 활용한 주민공동텃밭 조성 사례를 분석함으로써 사업실현을 위한 다양한 주체의 역할을 도출하고 제도적 지원방안을 모색하였다. The improvement of physical environments as a residential project for regenerating deteriorated residential area has shown a limit in bringing population influx and community restoration. Especially the grid pattern street improvement in natural parcels produced lots of vacant areas and revealed the limit in increasing reconstruction for the vacant and deserted houses. This study proposes, as an integrated neighborhood regeneration strategy, that the deteriorated residential area can be restored effectively by using it as vegetable gardens. As research methods, the function and possibility of vegetable garden were investigated by the review of previous studies. The scale, shape, cause, and present using status were also analyzed, and classified into four types. The study identifies the role of residents, administration, and intermediary supporting organization in making residents? community vegetable garden with deserted house type.

Metabolic syndrome (MS) is associated with serious health issues worldwide. The purpose of this study was to examine the effect of 12 weeks of combined exercise training on body composition and metabolic syndrome factors in Korean female college students. Subjects were randomly assigned to the exercise (n=10) and control (n=10) groups. The exercise group trained for 80 minutes/day for 3 days/week during the 12 weeks. Each exercise session comprised 3 phases: warm up for 10 minutes, main exercise for 60 minutes (aerobic exercise, 30 minutes; resistance exercise, 30 minutes), and cool down for 10 minutes. The exercise intensity for aerobic exercise was maintained at 60 - 80% of the heart rate reserve for 30 minutes; and that for resistance exercise was 10 - 15 repetitions maximum for 30 minutes. Two-way repeated analysis of variance was used for statistical analysis. Interaction effects (time × group) were not observed for body composition factors such as weight, body mass index, and body fat (%) and MS-related factors such as waist circumference; systolic blood pressure; diastolic blood pressure; and levels of triglycerides, glucose, total cholesterol, and low-density lipoprotein (p>.05). However, interaction effects (time × group) were observed for muscle mass (p=.032) and high-density lipoprotein levels (p=.006). Thus, we concluded that a 12-week supervised combined exercise program could not effectively improve body composition and MS-related factors in Korean female college students.

The purpose of this study was to examine the effects of a 12-weeks combined exercise training program on visfatin, resistin, and metabolism-related hormones in Korean female college students. The subjects were randomly assigned to the exercise (n=10) and control (n=10) groups. The combined exercise group was trained for 80 minutes per day for 3 days a week during the 12 weeks. The training regimen comprised the following 3 sessions: warm-up for 10 minutes, combined exercise for 60 minutes, and cool-down for 10 minutes. On the other hand, the control group was asked to maintain their daily normal and sedentary activities. The intensity of aerobic exercise was 60-80% of heart rate reserve for 30 minutes and that of the resistance exercise was 10-15 repetition maximum for 30 minutes. Two-way repeated ANOVA was performed. No interaction effects (time X group) were observed on the levels of visfatin, resistin, glucagon, adrenocorticotropic hormone, and cortisol between exercise and control groups (p>0.05). However, the interaction effects (time X group) on the levels of insulin (p=0.007) was observed. We conclude that 12 weeks of combined exercise affected the levels of insulin; however, it did not affect the levels of visfatin, resistin, glucagon, adrenocorticotropic hormone, and cortisol in Korean female college students.

알츠하이머병은 신경퇴행질환으로 뇌조직에서 발생하는 아밀로이드 베타(amyloid-β, Aβ) 펩타이드의 축적과 응집, 타우 단백질의 초인산화, 고농도의 특정 금속이온 축적에 의해 발병하는 것으로 알려져 있다. 현재까지 효과적인 치료제가 개발되지 못하였기 때문에, 알츠하이머병을 초기에 정확하게 진단하는 기술은 매우 중요하다. 알츠하이머병의 진단을 위해 개발된 다양한 기법 중 형광 프로브를 이용한 알츠하이머병의 바이오마커 영상화는 많은 연구자들의 관심을 받고 있다. 본 리뷰 논문에서는 최근 개발된 알츠하이머병 진단용 형광 프로브의 구조와, 체내 뇌 영상화에의 적용을 소개하고자 한다. 본 논문은 향후 새로운 프로브를 개발하고자 하는 연구자들에게 많은 도움이 될 것으로 기대된다. Alzheimer’s disease (AD), an irreversible degenerative disorder, is associated with accumulation and aggregation of amyloid-β peptides, hyperphosphorylated tau proteins, and high level of metal ions in the brain. Up to date, there is no effective therapeutic agent to stop the progress of the disease and thus early and accurate diagnosis of AD has gained increasing attention in recent years. Among several diagnostic methods, an optical imaging using fluorescent probes is one of the most promising tools to visualize AD biomarkers. In this review, we will introduce fluorescent probes that can be applied to in vivo brain imaging of AD models and also their structure. It is expected that the present review will provide useful information to many scientists in the related research fields.

생전분 분해효소를 이용한 타피오카의 당화 및 알콜 병행 복발효에 적합한 조건을 조사하였다. 그 결과 가수량 250%(v/w), 효소제 사용량 0.5%(w/w)를 사용하여 96시간 발효하였을 때 알콜 함량이 가장 높았다. 알콜발효 96시간째에 알콜함량 및 환원당은 11.7% 및 306 mg%으로 각각 나타났다. pH 변화는 발효초기 pH 6.2에서 발효 후 pH 4.2 범위로 감소하였으며, 총산은 발효초기 0.11에서 0.43까지 증가하였으나 큰 변화는 없었다. 알콜성분은 ethanol, methanol, iso-propanol, n-proylalcohol, iso-butylalcohol 및 iso-amylalcohol이 분석되었으며 그외에 acetaldehyde가 확인되었다. 생전분 분해효소제를 이용한 타피오카의 알콜발효 조건은 가수량 250%, 효소제 0.5%로 설정할 수 있었다. 그러나 전반적인 발효수율은 증자방법에 비하여 낮게 나타났다. The optimum conditions of the alcohol fermentation with raw tapioca by simultaneous saccharification and alcohol fermentation (SSAF) were studied using raw starch enzyme. The optimum conditions for maximum alcohol production were 0.5% (w/w) of enzyme content, 250% (v/w) of added water content and 96 hr of fer- mentation time. The alcohol and reducing sugar contents were 11.7% and 306 mg% after 96 hr fermentation, respectively. During the fermentation pH decreased from 6.2 to 4.2 and total acidity increased from 0.11 to 0.43. Alcohol components were detected such as ethanol, methanol, iso-propanol, n-propylalcohol and isobutylalcohol, besides acetaldehyde. We could construct raw starch fermentation conditions which was 250% (v/w) of added water content and 0.5% (w/w) of enzyme content. However, yield of raw starch alcohol fermentation was lower than that of steaming alcohol fermentation.

To begin with, 1st grade students; both boy and girls, showed similarities of lacking agility through the process of this experiment. In detail, for boys during cardiopulmonary endurance and for girls when muscular strength was needed they appeared to be in the same poor physical state. Therefore in suggestion relating to the ACSM prescription, continuously exercising by fast walking, jogging and new sports like healthrobics is recommended. For the 2nd grade students, results appeared the same, but in this case traditional activities (rolling steel ring, shuttlecock game, rubber string game, skipping) is suggested to build up not only the agility and physical strength but to help balance and improve the growth factor in these group of students. The muscular strength of 3rd grade students turned out to be even weaker than the other grades. In this case the neccessity of strengthening abdominal, back and hip muscles was brought up. This will improve not only the physique, but allow strained muscles to become flexible resulting in straightening body posure of these students. To do achieve this windsor pilates exercising programme is recommended as it focuses on maintaining the whole body balance using variety of physical movements. By doing these kind of exercises from a young age could possibly have an habitual effect on students to begin exercising for health related purpose. It is important that we provide these physical education environment for the students. Lastly, survey was carried out examining the daily routine of these students. Female students in the 1st grade answered that they spend more than 2hours on using computers or watching tv (33.4%). By looking at this survey result we can suggest that parents should take condern and can exercise with the students such as skipping outside the house and going for a walk to reduce the student`s time spent on electronic devices. Some female student answered that they occasionally exercise, but not as a daily routine. Research also showed that the 1st grade students have breakfast and sleep on average of over 8hours a day. But as the students grew older to 2nd and 3rd grade, their answers tended to change that they sleep less and also sometimes missing out on breakfast meals. Parents and caregivers interest on these age group of students is vitally needed.
