The purpose of this study is to determine the possibility of using Agarum cribrosum as a natural health food source. To accomplish this purpose, the contents of the general and antioxidant activities of Agarum cribrosum were measured. The contents of carbohydrate, crude protein, crude lipid and ash were 45.4%, 15.0%, 2.3% and 33.1%. The calories of Agarum cribrosum were 262.3 kcal and total dietary fiber of Agarum cribrosum was 34.0%. The protein contained a total of 18 different kinds of amino acids. The content of amino acids was 12,402.42 mg/100 g. The K was the largest mineral followed by Ca, Na and Mg, implying that Agarum cribrosum is an alkali material. The antioxidant activity of Agarum cribrosum was assessed by various radical scavenging assays using DPPH (2,2-diphenyl-1-picrylhydrazyl), FRAP (ferric ion reducing antioxidant power), reducing power, and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)). All antioxidant activity of Agarum cribrosum extract increased the concentration of the dependents. Total phenolic contents of Agarum cribrosum extract were $34.1{\pm}2.56mg/g$, and total flavonoids contents were estimated at $4.9{\pm}0.26mg/g$. General nutrients and other antioxidant bioactive materials in Agarum cribrosum were also potential materials for good health food. It is expected that a follow-up study of Agarum cribrosum through developing processed food and evaluation of their functional properties would provide useful information or sources of functional foods.

This study examined the physicochemical properties of radish pickle containing different natural preservatives (grapefruit seed extract, green tea extract, rosemary, or olive) stored for 0, 1, 2, 3, and 4 weeks. The hardness and color of the radish pickles with the grapefruit seed extract was higher than the other radish pickles during storage from week 0 to week 4. A 14.52% and 13.80% decrease in hardness and color were observed in the radish pickles with grapefruit seed extract (GFE), respectively. In addition, the total phenolic content was highest in the GFE in natural preservatives. Based on the results, GFE was selected as the optimal natural preservatives, and the growth of total viable bacteria and yeast were evaluated. The total viable bacteria and yeast showed similar patterns to the control. These results are expected to be useful in producing radish pickles with optimal quality and contribute to the development of various foods in the food industry.

This study typified the rural centers with myeon locations in Hwasun-gun which showed comprehensive and various class types through settlement class structure analysis. It is also for establishing the awareness of strengthening functions and facilities of the centers and the directions of strengthening it. Subjects of the study could be classified into three types including base type (Neungju-myeon), general type (Nam-myeon) and decline type (Dongbok-myeon) through the analysis of settlement class structure. Neungju-myeon location as the base type could function as the myeon location by itself and tended to serve education, health and welfare functions through the strengthening of central living functions. Nam-myeon location as the general type required sports facilities management based on the vicinity and accessibility to the senior's welfare functions. Dongbok-myeon location as the decline type required the accessibility to public health facilities and the security of vicinity to the facilities because of its high population of the aged.

EPC Network 기반 RFID 응용 시스템의 성능 향상을 위한 EPCIS 주소별 그룹 질의 기법

박성진,김대환,손민영,염근혁,Park, Sung-Jin,Kim, Dae-Hwan,Son, Min-Young,Yeom, Keun-Hyuk 한국정보처리학회 2011 정보처리학회논문지D Vol.18 No.2

These days RFID application has been developed rapidly. It has been applied to many business areas such as logistics and supply chains. The Electronic Product Code (EPC) Network Architecture, an open global standard, is proposed by EPCglobal for developing RFID enabled systems. People who want to obtain the product information which are master information and event information have to apply with EPC Network Architecture. However, EPCIS which has master information and event information has to be accessed base on each EPC. Therefore, there is lots of duplicate accessing to EPCIS because RFID application has to access the same EPCIS over again which makes all performance down in EPC Network. This paper proposes how to reduce access times to EPCIS using EPC grouping based on EPCIS address. We build EPC Network environment to experiment about performance of RFID application system and we prove the improvement of EPC Network. Our result shows the reducing the EPCIS communication time by maximum 99 percentages. 오늘날 RFID 응용 시스템은 점차 발전되고 물류, 유통, 항만 그리고 제조 등 다양한 산업분야에서 적용되고 있다. RFID 응용 시스템 개발을 위한 국제 표준으로 EPCglobal 에서는 EPC Network 아키텍처를 제시하고 있다. EPC Network 아키텍처를 통해 개체의 고유정보(master information) 및 이력정보(event information)를 수집해야 한다. 그러나 개체의 고유정보 및 이력정보를 저장하고 있는 EPCIS의 경우는 수집된 EPC와 각 개체가 가지는 이력정보의 수에 의존적으로 통신 횟수가 증가하며, 개별적인 EPC에 대한 처리로 인해 동일한 EPCIS와 여러 번 통신해야 하는 문제점이 존재한다. 이러한 문제점은 EPCIS와의 통신시간의 증가로 인해 RFID 응용 시스템의 성능을 저하 시키게 된다. 따라서 본 논문에서는 EPCIS와의 통신 시간을 감소시키기 위하여 동일한 EPCIS와의 통신을 제거하는 EPCIS 주소별 그룹 질의 기법을 제시한다. 또한, 본 논문에서 제시한 기법을 적용하고 실제 EPC Network 환경을 구축하고 다양한 실험을 통하여 효용성을 검증하였으며 EPCIS의 통신 시간이 최대 99% 감소하는 것을 확인할 수 있었다.

This study assumes that though buildings have identical color of the outer walls, their colors and images make the difference according to neighboring environmental factors and visual range. Based on the assumption, it carries a quantitative analysis of physical and image difference, targeting colors of the outer walls of high-rise apartment buildings within apartment complex. As a result, it is identified that the outer colors of the buildings on the streetside of high-rise residential complexes are significantly different according to neighboring environmental factors and viewers' visual range. And, it is suggested that in planning colors of outer wall, colors should be arranged in consideration of color difference according to visual range.

전자기 듀오캐스팅으로 제조한 Al-Mn/Al-Si 하이브리드 알루미늄합금의 미세조직과 인장 특성

박성진,김종호,박준표,장시영,Park, Sung-Jin,Li, Tingju,Kim, Chong-Ho,Park, Jun-Pyo,Chang, Si-Young 한국재료학회 2012 한국재료학회지 Vol.22 No.2

The microstructure and tensile properties of Al-Mn/Al-Si hybrid aluminum alloys prepared by electromagnetic duocasting were investigated. Only the Al-Mn alloy showed the typical cast microstructure of columnar and equiaxed crystals. The primary dendrites and eutectic structure were clearly observed in the Al-Si alloy. There existed a macro-interface of Al-Mn/Al-Si alloys in the hybrid aluminum alloys. The macro-interface was well bonded, and the growth of primary dendrites in Al-Si alloy occurred from the macro-interface. The Al-Mn/Al-Si hybrid aluminum alloys with a well-bonded macro-interface showed excellent tensile strength and 0.2% proof stress, both of which are comparable to those values for binary Al-Mn alloy, indicating that the strength is preferentially dominated by the deformation of the Al-Mn alloy side. However, the degree of elongation was between that of binary Al-Mn and Al-Si alloys. The Al-Mn/Al-Si hybrid aluminum alloys were fractured on the Al-Mn alloy side. This was considered to have resulted from the limited deformation in the Al-Mn alloy side, which led to relatively low elongation compared to the binary Al-Mn alloy.

<b>Purpose:</b> To investigate clinical availability of AL-ScanTM (Nidek, Gamagori, Japan) by comparing corneal refractive power with AL-ScanTM, AutokeratometerTM (Topcon KR-1, Tokyo, Japan) and PentacamTM (Oculus, Wetzlar, Germany) devices. <b>Methods</b>: Seventy-one patients (142 eyes) who visited our hospital for refractive surgery were tested using AL-Scan<sup>Ⓡ, Autokeratometer and Pentacam<sup>Ⓡ and corneal refractive power was compared among devices. <b>Results:</b> When comparing measurements with AL-Scan<sup>Ⓡ, Autokeratometer and Pentacam<sup>Ⓡ, the mean corneal refractive power was 43.37 ± 1.32 D (2.4 mm zone), 43.35 ± 1.32 D (3.3 mm zone), 43.36 ± 1.35 D, and 43.35 ± 1.36 D respectively and showed no significant differences. Corneal refractive power had strongly positive linear correlation (<em>p </em>< 0.001) and Bland-Altman plots showed high degree of agreement among AL-Scan<sup>Ⓡ, Autokeratometer and Pentacam<sup>Ⓡ devices. <b>Conclusions:</b> Because measuring ocular biometry with AL-Scan<sup>Ⓡ including axial length, intraocular lens power calculation and topography simultaneously is possible, clinical use is convenient. Corneal refractive power was not different when compared with autokeratometer and Pentacam<sup>Ⓡ, thus, AL-Scan<sup>Ⓡ can be used in the clinical environment.

원통형의 압접소자를 이용한 광지연선을 사용하여 광 간섭형 단층촬영 시스템을 제작하였다. 광지연선은 18 m 길이의 단일 모드 광섬유를 압전소자의 둘레에 134회 감아 구성하였으며 0.78 mm의 광경로 길이변화를 얻었다. 제작한 광 간섭형 단층촬영 시스템은 신호 대 잡음비 96.9 dB, 종방향 분해능 $18.6{\pm}0.5\;{\mu}m$, 횡방향 분해능 $5\;{\mu}m$의 특성을 보였다. We demonstrate a compact optical coherence tomography(OCT) system based on the optical fiber delay line controlled by a cylindrical piezo-electric transducer(PZT). An 18-m length of single mode fiber is wrapped under constant tension around a PZT. Approximately 134 windings are used. Wraps of the long length of fiber allow the small expansion of the PZT to be magnified to an optical path length delay of 0.78 m. The OCT system shows characteristics for 2-dimensional imaging, exhibiting 96.9dB of signal-to-noise ratio(SNR), $18.6{\pm}0.5\;{\mu}m$ of axial resolution, and $5\;{\mu}m$ of lateral resolution with samples.

This study was prepared to investigate the correlation between Sasang constitutional groups and voice characteristics using voice analysis system(in this study, CSL). I focused on the voice characteristics in terms of harmonics, Formant frequency and Formant Bandwidth. The subjects were 71 males. I classified them into three groups, that is Soeumin group, Soyangin group and Taeumin group. The classification method of Constitution used two ways, QSCCII(Questionnarie for the Sasang Constitution Classification II) and Interview with a specialist in Sasang Constitution. So 71 people were categorized into 31 Soeumin(people), 18 Soyangin(people) and 22 Taeumin(people). Pitch is approximately similar to the fundamental frequency(F0) in voices. Shimmer in dB gives an evaluation of the period-to-period variability of the peak-to-peak amplitude within the analyzed voice sample. FFT(Fast Fourier Transform) method in CSL can display sampled voices into harmonics. H1 is the first peak and h2 is the second peak in the harmonics. The amplitude difference of h1 and h2(h1-h2) can be explained as the speaker's phonation type, And Formant frequency and bandwidth can be explained as the speaker's vocal tract. So I checked the harmonics and Formant frequency and Bandwidth as the voice parameters. First I have captured /e/ voices from all subjects using microphone. And then I analyzed /e/ voices with CSL. Power Spectrum and Formant History is the menu in the CSL which can display harmonics and Formant frequency and bandwidth. The results about the correlation between Sasang Constitutional Groups and voice parameters are as follows; 1. There is no significant amplitude difference of harmonics(h1-h2) among three groups. 2. There is the significant difference between Soeumin Group and Soyangin Group in Formant Frequency 1 and Formant Bandwidth 1(p<0.05). Any other parameters have no significance. I assume that Soyangin Group has clearer and brighter voice than Soeumin Group according to the Formant Bandwidth difference. And I think its result has coincidence with the context of "Dongyi Suse Bowon" and "Sasangimhejinam".
