Various environmental problems due to rapid industrialization and urbanization have worsened to such an extent that they threaten the environmental restitution of the globe and become a critical international issue. Korean government has presented the concept of green growth as a new state vision for the next 60 years and is making efforts to solve these environmental problems. Daegu Metropolitan City has faced various environmental problems including overpopulation of the city, traffic pollution, household waste accumulation and the green zone problem because of the increase of urbanization over the last few decades. As such urbanization continues, the quality of residential environments is rapidly deteriorating and the intensive use of the land leads to an increase of building area, raising the temperatures of cities. There have therefore been demands for healthy, pleasant and satisfying residential environments and for the improvement of existing residential environments, and this demand has been fully recognized by society. Nevertheless, current residential complex developments concentrate only on raising the efficiency of land use. In related laws of the past (Daegu Metropolitan City, Urban Planning Municipal Ordinance as of October 10, 2003) an attempt was made to impose a standard to segmentalize the building-to-land ratio, floor area ratio and regulations of number of floors vertically. However, these laws have now been abolished and the regulations are being eased. The purpose of this study was to analyze the characteristics of the floating wind before and after the vertical segmentation of residential areas (Daegu Metropolitan City, Urban Planning Municipal Ordinance as of October 10, 2003) by using KLAM_21, a model that enables analysis and prediction of the flow and generation of cold wind. The purpose is also to present a plan to improve the quality of residential areas when developing a building lot and redeveloping housing areas.

The objective of this study is to obtain the basic data for investigating the effects of organic reserves on winter survial or regrowth yield. Forage rape (Brussicu napus L.) was sown at 10 day> interval from Sep. I to Nov. 1. Field-grown palnts were sampled on the before wintering (Dec. 4) and on the wintering period (Jan. 16) to analyze the nitrogen and non-structural cahohydrate reserves. The rate of winter survival and regrowth yield were also measured in the spring of next year. On the before wintering, the dry matter yields from the plots sown on Sep. 1, Sep.11 and Sep. 21 were 860, 596 and 260 kg/lOa, respectively. No. harvest was canied out on the plots sown after Oct. 1 because the growth state was not enough to cut. Both of nitrogen and starch contents per plant significantly increased as the seeding date was later. On the wintering period, the contents of nitrogen reserves in roots were 176.8. 120.1, 71.7, 84.0, 72.1, 45.3 and 33.3 mg/plant, those of starch reserves were 199.0. 55.8, 21.8, 92.6, 86.5, 36.4 and 29.0 mglplant, resepctively, in the plots sown on Sep. 1, Sep. 11, Sep. 21, Oct. I, Oct. 11, Oct. 21 and Nov. 1. The rates of winter survival were 40, 36, 33, 85, 87, 59 and 49% and regrowth yields were 161, 86, 65, 520, 451, 121 and 33 kgD.M/lOa, respectively, in each plots. 'Ihese results clearly showed that seeding date has a close influence on the level of organic reserves and forage yield, and that the possibility of continuous utilization on the before and alter wintering is extremely limited by seeding date.

Objectives : The aim of this clinical experiment was to investigate the effect of KamiWooseul-tang on low back pain and kidney function. Methods: We investigated 64 low back pain patients. We treated the patients with acupuncture, bed rest, herbal medicine, physical therapy. The patients were divided into two groups as follows, 32 patients (with normal renal function) were treated with only KamiWooseul-tang. Another 32 patients were treated with a commonly used herbal medicine. Results : The obtained results are summarized as follows. The patients were 43.8% male and 56.2% female. Their age were 20s 15.6%, 30s 25%, 40s 17.2%, 50s 9.3%, 60s 18.8% 70s 12.5% and 80s1.6%. Duration is most common in the most acute stage (< 1 week), next was chronic stage ( >6 months ), acute stage (1 week ~ 1 month) and subacute stage(l months ~ 6 months) in turn. Cure rate increased step by step after herb-medicine administration. Duration of patients had no relation with cure rate(P>0.05). The KamiWooseul-tang was more effective than the commonly used herbal medicine after 3 weeks therapy (P<0.05). Serum BUN and Creatinine level in KamiWooseul-tang group changed from $14.69{\pm}4.0,{\;}0.76{\pm}0.19(mg/dl)$ before adminstration to $13.64{\pm}3.92{\;}0.77{\pm}0.19,{\;}13.48{\pm}3.00{\;}0.82{\pm}0.21,{\;}13.26{\pm}3.73{\;}0.87{\pm}0.21(mg/dl)$ at 7th, 14th, and 21st days of administration respectively. Urinalysis showed no specific change in the KamiWooseul-tang group. During medication serum-electrolyte was within normal range. Conclusion : Therefore KamiWooseul-tang was more effective than the commonly used herbal medicine and there was no clinically remarkable difference in the serum BUN, Creatinine level, urinalysis and serum electrolyte between pre-medication and post-medication in the KamiWooseul-tang group.

21세기에 컴퓨터는 모든 분야에 많은 영향을 미치고 있다. 음악도 예외는 아니어서 컴퓨터음악이 차세대의 새로운 음악으로 등장하고 있다. 특히, 21세기 컴퓨터음악의 중심은 20세기의 미디음악에서 컴퓨터를 하나의 악기로 사용하는 실시간 음악으로 옮겨지고 있다. 대부분 유럽의 국가들과 미국은 이 실시간음악에 대한 많은 연구와 연주가 이루어지고 있는 반면 정작 IT강국으로 알려진 한국에서는 새로운 미디어와 실시간 음악에 대한 중요성을 잘 인식하지 못하고 있어 이 분야의 발달이 부진한 실정이다. 본 논문에서는 컴퓨터음악의 분야 중 우리나라에서 실시간 음악 활용의 가능성을 제안한다. 특히, 이러한 제안은 실시간 음악을 활용하여 제한된 음역과 기술 등으로 국제적인 악기가 되고 있지 못한 전통 국악기의 단점을 극복할 수 있는 가능성을 시사한다. 이러한 가능성은 한국작곡가들에게 매우 유리한 장점이 될 것이라 사료된다.

An 8-year-old Thoroughbred mare showing anestrus for longer than 6 months with left ovarian mass was referred to Veterinary Medical Teaching Hospital of Seoul National University. For 6 months, the mare had received 2 times hormonal therapies with $PGF_2{\alpha}$ and progesterone. The mare had not responded to these therapies and not shown estrous behavior. On rectal palpation, the left ovary was enlarged and contralateral ovary was small and inactive. Transrectal ultrasonographic examination of the left ovary revealed a mass composed of multiple, irregularly shaped follicles. Granulosa cell tumor (GCT) was suspected according to her history. Ovariectomy was performed through the left flank laparotomy with a standing position in a simple chute located outside of horse farm. The mass was diagnosed as GCT on histopathology. The mare was recovered without any problem and became pregnant next spring.

The 21st centurt, the era of change-space, is requesting us to readjust our education system. In other words, we should renew it by looking back into the past cultivate more advanced ideas. As a matter of fact junior colleges have been considered just as miniture of universities in every way such as curriculum, prossor emploment, school affairs, etc. Therefore we should change our existing education system not to be criticized for the next century. May students are trained for industry as dental technicians in our department of college. We should educate experiment and practice substantially as college professors as well as exert ourselves in developing our abilities to adapt to high diverse industrial technique, putting emphasis on practice more than theory. It is mecessary for us to sufficiently teach the technique to good students and make them display their abilities in order to produce high quality goods. Reinvestment ineducation is a condition precedent. Dental laboratories have just employed the students that graduated from our college. However it's time for a change. They should pay attention to our education and assist us in all respects with the thought of equally educating professional dental technicians together with us. The field practice system is subject to reinforcement so that our students have more opporunities of utilizing the tools and materials for practice. Finally we should not only carry out new reserch more deeply no less than dental technicians who are experienced in business for development of education system but endeavor to meet pratical education by adding what is pratically needed in dental laboratories to the existing education system.

Three types of meongge (Halocynthia roretzi) jeotgal (MJ) were prepared with 3 different types of salts (12%, w/v): purified salt (PS), solar salt aged for 3 years (SS), and bamboo salt that had been recrystalized 3 times (BS). One set of MJ was fermented with starters, Bacillus subtilis JS2 and Tetragenococcus halophilus BS1-37 (each 6 log CFU/g), and another set without starters for 42 days at $10^{\circ}C$. The LAB count of the SSMJ (non-starter) was highest at day 28 (2.30 log CFU/g). The pH of the PSMJ and SSMJ was 5.72-5.77 at day 0, and 5.40-5.50 at day 42. BSMJ showed higher pH and lower titratable acidities than other samples. Amino-type nitrogen (ANN) increased continuously, and SSMJ showed higher values than other samples from day 14. Bacterial species of non-starter MJ were examined by culture independent method. Clone libraries of 16S rRNA genes were constructed in Escherichia coli from total DNA from non-starter MJ samples at day 0, 14, and 28. Thirty clones per each sample were randomly selected and DNA sequences were analyzed. Variovorax sp., uncultured bacterium, and Acidovorax sp. were the most dominant group at day 0, 14, and 28, respectively. Lactobacillus sakei and Streptococcus sp. were the next dominant group in SSMJ at day 28. A Streptococcus sp. was detected from PSMJ at day 28. Sensory evaluation for MJ samples at day 28 showed that SSMJ got higher overall acceptability scores. These results showed that solar salt can cause desirable changes in the microbial community of fermented foods, thereby positively affecting their overall quality.

As far the current severe coronavirus disease 2019 (COVID-19), respiratory disease is still the biggest threat to human health. In addition, infectious respiratory diseases are particularly prominent. In addition to killing and clearing the infection pathogen directly, regulating the immune responses against the pathogens is also an important therapeutic modality. Sirtuins belong to NAD+-dependent class III histone deacetylases. Among 7 types of sirtuins, silent information regulator type-1 (SIRT1) played a multitasking role in modulating a wide range of physiological processes, including oxidative stress, inflammation, cell apoptosis, autophagy, antibacterial and antiviral functions. It showed a critical effect in regulating immune responses by deacetylation modification, especially through high-mobility group box 1 (HMGB1), a core molecule regulating the immune system. SIRT1 was associated with many respiratory diseases, including COVID-19 infection, bacterial pneumonia, tuberculosis, and so on. Here, we reviewed the latest research progress regarding the effects of SIRT1 on immune system in respiratory diseases. First, the structure and catalytic characteristics of SIRT1 were introduced. Next, the roles of SIRT1, and the mechanisms underlying the immune regulatory effect through HMGB1, as well as the specific activators/inhibitors of SIRT1, were elaborated. Finally, the multitasking roles of SIRT1 in several respiratory diseases were discussed separately. Taken together, this review implied that SIRT1 could serve as a promising specific therapeutic target for the treatment of respiratory diseases.
