We have investigated the optical properties of the global haze on Titan from spectra recorded between 7100 and $9200{\AA}$, where $CH_4$ absorption bands of various intensities occur. The Titan spectra were obtained on Feb. 23, 2005 (UT), near the times of the Cassini T3 flyby and Huygens probe, using an optical echelle spectrograph (BOES) on the 1.8-m telescope at Bohyunsan Observatory in Korea. In order to derive the optical properties of the haze as a function of altitude, we developed an inversion radiative-transfer program using an atmospheric model of Titan and laboratory $CH_4$ absorption coefficients available from the literature. The derived extinction coefficients of the haze increase toward the surface, and the coefficients at shorter wavelengths are greater than those at longer wavelengths for the 30 - 120 km altitude range, indicating that the Titanian haze becomes optically thin toward the longer wavelength range. Total optical depths of the haze are estimated to be 1.4 and 1.2 for the 7270 - $7360{\AA}$ and 8940 - $9150{\AA}$ ranges, respectively. Based on the Huygens/DISR data set, Tomasko et al. (2005) reported total optical depths of 2.5 - 3.5 at $8290{\AA}$, depending on the assumed fractal aggregate particle model. The total optical depths based on our results are smaller than those of Tomasko et al., but they partially overlap with their results if we consider a large uncertainty from possible variations of the $CH_4$ mixing ratio over Titan's disk. We also derived the single scattering albedo of the haze particles as a function of altitude: it is less than 0.5 at altitudes higher than ${\sim}150\;km$, and approaches 1.0 toward the surface. This behavior suggests that, at altitudes above ${\sim}150\;km$, the average particle radius is smaller than the wavelengths, whereas near the surface, it becomes comparable or greater.

$20^{\circ}C$에서 15일 동안 저장기간별 사과의 변화를 살펴본 결과는 다음과 같다. 사과의 중량과 수분은 저장기간 경과에 따라 점차적으로 감소하는 결과를 보였으며, 사과의 저장 중 가용성 고형물 함량은 저장 4일차까지 최고치로 증가하였다가 서서히 낮아지는 경향을 나타냈다. 사과의 저장 중 유기산 산도는 저장 5일차에 급격히 감소하다가 완만히 감소하였으며, pH는 저장기간에 따라 완만히 증가하는 경향을 나타내었다. 저장 중 사과 껍질의 색상을 측정한 결과, L값은 저장기간에 따라 서서히 증가하였으며, a값은 저장 3일까지 감소하였고, 저장 5일에 증가되었다가 그 이후 점진적으로 감소하였다. b값은 저장 6일에 최저치를 보인 후 서서히 증가하는 경향을 보였다. 사과의 조직감을 측정한 결과, 저장기간이 증가됨에 따라 사과의 경도는 전반적으로 감소하였다. 저장 기간에 따른 사과의 총 페놀과 총 플라보노이드 함량을 측정한 결과, 총 페놀 함량은 저장 기간이 길어질수록 감소하는 경향이 나타났으며, 저장 3일차에서 저장 4일차에 큰 폭 감소하였다. 총 플라보노이드의 변화 결과, 1일차에 비교적 크게 감소하였고, 실험 7일차에서 8일차 사이에 급격히 감소하였다. 저장 기간에 따른 사과의 DPPH 전자공여능 측정결과, 저장기간이 증가할수록 DPPH 전자공여능은 감소하였으며, Vit. C 함량의 경우 저장 기간이 길어질수록 감소하였는데, 특히 저장 4일차에 비교적 크게 감소하였다. 사과의 관능평가 수행 결과, 저장기간이 경과함에 따라 외관의 좋은 정도는 0일차에 6.75에서 15일차 2.83으로 크게 감소하였으며, 신맛의 좋은 정도는 저장 기간에 따라 유의적인 차이를 보이지 않았으나, 전반적으로 감소하는 경향이었다. 단맛의 좋은 정도와 아삭함의 좋은 정도에서는 0일차에 각 6.25, 5.33으로 가장 높았으며, 15일차에 각 3.92, 2.83으로 유의적으로 감소하였다. 종합적인 기호도에서는 7일차와 8일차 사이에 5.00에서 3.50으로 비교적 큰 폭 감소하였으며, 15일차에 2.00으로 저장 기간에 지남에 따라 유의적으로 감소하였다. 이상의 실험결과, 사과 저장 시 3~4일차에 유의적인 차이를 보였으며, 저장 8일 이후에는 모든 항목에 있어 측정감이 크게 변화하는 경향을 나타내었다. 따라서 $0{\sim}1^{\circ}C$에서 장기 저장한 사과를 $20^{\circ}C$ 전후에서 저장 및 판매할 경우, 최고의 품질을 위해서는 3일 내에 판매할 것을 권장하며, 8일 이내에 재고를 소진할 수 있도록 유통 기간을 조정하는 것이 바람직할 것으로 사료된다. This study was performed in order to compare the changes in Korean apples' qualities and antioxidant activity when stored at room temperature, $20^{\circ}C$, for fifteen days. The results showed that the weight, moisture content, soluble solid content, acidity, and hardness levels decreased as the storage period increased. However, pH and color value L increased as the storage period increased. Total phenol contents, total flavonoids contents, DPPH free radical scavenging activity, and vit. C contents of apples significantly decreased with increased storage period. Sensory parameters, such as appearance, sweetness, sourness, crunchiness, and overall acceptability of apples, also decreased as the storage period increased. Based on these results, if, the apple are being stored around $20^{\circ}C$, then, to have the highest quality, the apples should be sold within three days, We also suggested that it is desirable not to store the apples fore more than eight days.

In this study, silicon dioxide (SiO2) lms were deposited at temperatures below 200C by using the inductivity coupled plasma chemical vapor deposition (ICP CVD) technique. The breakdown electric eld of as-deposited SiO2 lm by using this method shows values as high as 8.6 MV/cm. Additionally the eects of post-metallization annealing on SiO2 were investigated. After 400C annealing, the capacitance-voltage (C-V) characteristics such as at-band voltage, and interface trap density are improved considerably. In TFTs fabricated on single crystal SOI substrates at low temperatures below 400C by using this gate dielectric, a sharp gate voltage swing of 85 mV/dec. with high electron mobility was obtained. ICP CVD, by using high density plasma, can realize an excellent SiO2 lm and is expected to be applicable for the gate oxide in high performance Si TFT on plastic as well as on glass substrate.

Hidradenitis suppurativa (HS) is a chronic, inflammatory and painful skin disease with recurrent nodules and tracts involving the intertriginous regions. It is known that the patient with HS shows an increased risk of metabolic disorders such as diabetes, metabolic syndrome and autoimmune diseases. Klinefelter syndrome (KS) is a sex chromosomal disorder occurring in males due to an abnormality of sexual differentiation, characterized by 47, XXY karyotype. Also, KS is related with somatic comorbidities such as metabolic syndrome, autoimmune and rheumatologic disorders as HS is. We report a HS patient with KS who shows a big improvement while on tumor necrosis factor-alpha inhibitor treatment. (Ann Dermatol 31(4) 446∼449, 2019)

Ji Sim Jung,Kyu Sik Cho,Jin Jang 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.42 No.III

We studied the deposition of a well-ordered pentacene film by vapour phase deposition. The optimizations of the growth of pentacene are carried out by varying the gas pressure in the reactor and substrate temperature. We found that the grain size depends strongly on the gas pressure in the reactor. The grain size of 20 $\mu$m has been obtained at the gas pressure of 200 Torr. The film was found to be strongly (001) oriented and its grain size decreases with decreasing the gas pressure.

정지희 ( Ji Hee Jung ),김정은 ( Jung Eun Kim ),유박린 ( Bark-lynn Lew ),심우영 ( Woo Young Sim ),강훈 ( Hoon Kang ) 대한피부과학회 2018 대한피부과학회지 Vol.56 No.3

Background: Recently, the number of patients with scalp or hair loss disorder has rapidly been increasing and patient concerns are growing accordingly. With the flood of inadequate information available, many patients depend on treatments of which efficacy has not been proven. Objective: To collect data on the awareness, knowledge, and behavior of scalp and hair loss disorders in Korean adults. Methods: Between June 2015 and May 2016, a total of 1000 dermatologic outpatients, who visited St. Paul’s Hospital and the Kyung Hee University Hospital at Gangdong were asked to complete a questionnaire. Results: Fifty-three percent of survey responders reported scalp-related symptoms and 44% of all responders indicated that they had alopecia. Most responders (90%) agreed that scalp and hair loss disorders should be treated, and more than 80% thought they should be treated by a dermatologist; although, they hesitated to visit dermatology clinics because of skepticism of treatment effectiveness or economic burden. It was observed that the patients rely heavily on scalp-related products such as shampoo, conditioners, and hair tonic, trusting their effects, which have not been verified to be effective. Conclusion: Although patients who have hair loss or scalp diseases need to be treated appropriately by confirmed diagnosis of dermatologists, they often depend on non-professional methods rather than visiting dermatologists. Therefore, dermatologists should concentrate their efforts on correcting the misunderstandings about scalp and hair loss disorders to reduce unnecessary social economic burden.
