This study was performed to develop and evaluate beverage prepared with optimally roasted seoritae to maximize the isoflavone content and antioxidant activities of the beverage. Isoflavone content was maximized at the roasting temperature of $110^{\circ}C$ for 20 min. Both DPPH radical scavenging activity and ABTS radical scavenging activity along with total polyphenol content were highest when seoritae was roasted at $110^{\circ}C$ for 20 min. Western blotting was used to determine the level of nuclear factor of activated T-cells 1(NFATc1) involved in controlling osteoclast differentiation. The results showed that NFATc1 had a concentration-dependent inhibitory effect when the RoS110 (roasted seoritae at $110^{\circ}C$ for 20 min) samples were processed at varying concentrations (10, 50, and $100{\mu}g/mL$). Tea samples were prepared from optimally roasted seoritae by varying brewing times (5~90 min) at $65^{\circ}C$, and tea brewed for 60 min had the highest preference with $65^{\circ}C$ as the preferred temperature for drinking.

Background: As nonsurgical interventions for vitiligo are not always successful, various surgical modalities have been used in patients with refractory vitiligo. Of these, non-cultured epidermal suspension transplantation (NCES) was recently introduced to treat large recipient sites using cells from small donor tissue. Objective: We assessed the effectiveness and safety of NCES as a surgical treatment for patients with refractory vitiligo. Methods: We retrospectively reviewed 20 cases in 17 patients (11 females; median age 25 years) who underwent NCES from July 2015 through March 2018. Suction blisters (20 mm in diameter) were collected from the patient’s inner thigh at a donor-to-recipient area ratio of 1:5. After the addition of 5 mL recombinant trypsin solution to the suction blisters, followed by incubation at 37°C for 60 min, epidermal cells were manually scraped off the blister surface, and epidermal cell suspension was obtained by centrifugation at 1,500 RPM for 5 min. The suspension was applied to the vitiligo regions after epidermal ablation of those regions. Phototherapy resumed 1 month later. Treatment success was defined as ≥75% repigmentation of the surgical site, and all adverse events were noted. Results: Overall, 85.0% of cases (17/20) exhibited treatment success. Adverse events included hyperpigmentation (20%) and surgical site infection (5%), but the treatment was tolerable in all cases. Conclusion: NCES is a reliable surgical option for patients with vitiligo refractory to nonsurgical treatment. Large areas of vitiligo can be treated by NCES, and use of this technique should be encouraged in Korea. (Korean J Dermatol 2018;56(7):426∼432)

Background: Cardiovascular disease (CVD) is a major clinical problem and the most common cause of morbidity and mortality in patients with chronic kidney disease (CKD). Coronary artery calcifi cation (CAC) is a potential mechanism that explains the association between renal function and cardiovascular mortality. We aimed to evaluate the association between renal function and CAC in apparently healthy Korean subjects. Methods: In 23,617 participants in the health screening program in Kangbuk Samsung Hospital health screening program from January 2010 to December 2011, estimated glomerular fi ltration rate (eGFR) was assessed by Cockcroft-Gault equation. Coronary artery calcium score (CACS) was measured by multi-detector computed tomography (MDCT). Subjects were divided into 3 groups according to the CKD Staging system with eGFR grade; stage 1: eGFR = 90 mL/min/1.73 m2, stage 2: eGFR 60-89 mL/ min/1.73 m2, stage 3: eGFR 30-59 mL/min/1.73 m2. Results: Mean age of the participants was 41.4 years, and mean eGFR was 103.6±21.7 mL/min/1.73 m2. Hypertension and diabetes were noted in 43.7% and 5.5% of the participants, respectively. eGFR showed weakly negative but signifi cant association with CACS in bivariate correlation analysis (r=-0.076, p<0.01). Mean CACS signifi cantly increased from CKD stage 1 to 3. The proportion of subjects who had CAC signifi cantly increased from CKD stage 1 to 3. Although odds ratio for CAC signifi cantly increased from stage 1 to 3 after adjustment for confounding factors, this signifi cance was inversed when age was included in the model. Age was the strongest factor that affects CAC. Conclusions: This study performed in young Korean subjects with relatively normal renal function, age was the mostly strongest effector on the association between eGFR and the degree of CAC.

This study focused on the expression technique and work manufacturing of nail design. Any woman that wants to be pretty is interested in nail design which is considered as a means to express beauty, intelligence and sensuality. These days, nail design carries heavy weight in completion of total fashion coordination. Good dress, elegant hair style, bright make-up and well-trimmed nails are requirements of modern women. These days, the range of nail design is more expanding and its importance is getting bigger. To maintain and establish such developmental flow properly, we have to break our stereotyped view on nails and accept it in open view. And we have to actively participate in development of new products and technologies and perform academic research on nail design. For the purpose, we have to consider further studies which contribute to understanding exact meaning of nails and necessity and importance of nails.

퇴비화에 있어서 중온성미생물과 고온성미생물의 유기물분해특성

정민정,김혜경,배재근 서울산업대학교 산업대학원 1996 大學院論文集 Vol.4 No.-

본 연구에서는 퇴비화과정중의 미생물을 분리하여, 분리된 미생물에 대한 기본적인 배양조건 및 미생물의 특성을 조사 하였으며, 또한 분리된 미생물을 퇴비화장치에 접종했을 때 퇴비화에 미치는 영향을 조사하여 퇴비화의 미생물분해 원리에 대하여 검토하였다. 퇴비화반응이 활발하게 진행되는 각 과정에서 중온성미생물(Mj-7)과 고온성미생물(Hj-8)을 분리하였으며, 이들을 각각 반응기에 접종시 중온성미생물을 주입한 반응조에서는 초기에 온도 상승폭이 높고, 유기물의 분해가 활발하게 진행되어 중온성미생물이 반응에 기여하는 정도가 높게 관찰되었다. 그러나 고온성미생물 주입시에는 반응속도가 느리고, 온도가 많은 시간이 경과된 후에 서서히 상승하였다. 퇴비화과정에서 저온성미생물이 중요한 역할을 하고, 저온성미생물의 우점화로 산화열이 발생되므로 고온성미생물이 유도된다고 볼 때 미생물을 초기 주입시에 저온성미생물의 주입이 효과적이라는 것이 증명되었다. 이들 분해에 관여하는 기여정도를 명확히 하기 위하여 중온성균과 고온성균을 혼합하여 주입하여 실험한 결과, 중온성균만을 주입한 것에 비교하여 초기온도상승은 거의 비슷했으나, 고온성균을 접종하므로서 고온을 유지하는 시간이 더욱더 길게 연장되고, 유기물의 분해가 더욱더 진전되는 현상이 관찰되었다. 이러한 결과로부터, 퇴비화에 관여하는 미생물의 원리는 중온성미생물이 초기에 우점화되어 유기물분해에 의해 산화열이 발생되어 고온분위기가 유지되면 고온성미생물이 우점화된다는 것이 증명되었다. 즉 고온성미생물을 분리하여 접종하는 것만으로는 반응을 원활하게 진행시키지 못하며, 반드시 중온균에 의하여 반응을 진행시키고, 그 산화열 및 분해산물에 의하여 고온성균이 서식 가능하도록 분위기를 유지한 후에 접종할 때 그 효과를 기대할 수 있다는 것이 확인되었다. Microorganisms under composting was separated and basic condition of culture for microorganisms and their property have been investigated. Additionally the effect to the process of composting when separated microorganism is inoculated to compost producing reactor was investigated and principle of biodegradation in connection with process of composting has been studied. In each process of active reaction for composting mesophilic microorganism(Mj-7) and thermophilic microorganism(Hj-8) were separated and when such microorganism was inoculated to reactor respectively it was found that in the reactor inoculated with mesophilic microorganism showed high range of initial temperature rise and degradation of organic matter was very active thus the level of contribution of mesophilic microorganism to reaction was high. However when inoculated with thermophilic microorganism the speed of reaction was very slow and gradual rise of temperatures after elapse of considerable time was observed. It is proved that inoculation of mesophilic microorganism initially is effective in light of inducing high temperature system microorganism through emission of oxidation heat by ignition of mesophilic microorganism playing significant role in the process of producing compost. To check on the level of contributions to biodegradation by respective microorganism both microorganism mentioned above mixed and inoculated and result showed that the initial rise of temperature was close to the time of inoculated of mesophilic microorganism however by addition of thermophilic microorganism duration for maintaining high temperature was lengthened and degradation of organic matter was advanced. From such result it is proved that in the process of composting initially mesophilic microorganism is ignited first emitting oxidation heat producing high ambient temperature then themophilic microorganism being kindled. In summary it has been proved that smooth reaction in composting can not be assured with innoculted of separated high temperature system microorganism alone but it is essential to initiate reactions by mesophilic microorganism and after maintaining environment amenable for presence for thermophilic microorganism inoculated of separated high temperature system by means of oxidation heat and degraded matter and its inoculation would produce desired result.
