This research focuses on the development of upcycled denim fashion designs, whichis a more specific category within general upcycled fashion design. Characteristics of upcycled fashion design, which has been identified previously by researchers, include the following traits: environmentality, uniqueness, aesthetic appeal, availability, convertibility, and deconstructivity. The expression principles include recycling, substitution, recombination, and reduction. The result of the analysis of the denim fashion design characteristics, which is based on the theoretical analysis, has found. The external expression pattern consists of the deconstruction and reconstitution of materials, the avant-garde style and convertibility, the ability to mix and match materials and techniques, the production of zero waste, and the use of layering. The expression techniques used included decomposition, depaysement, weaving, cut-off, collage, assemblage, overlapping, connecting, attaching, and stitching. The inner meanings were identified as economicality through recycling, convertibility through rearranging, and the rarity and value of hand-made products. The result of the research applying the identified characteristics are as follows. First, developing and creating designs using modified denim and sub-materials with various expression patterns and techniques could provide completely new images unlike existing denim products. Second, modifying the details while maintaining the basic format of denim clothing could provide unique and new possibilities for upcycled denim fashion design. Third, environment-friendly models with creative designs were developed by recycling used denim materials. This reduced waste and energy while maximizing the use of resources. This study expects contribute to upcycled fashion design research by recognizing the unique characteristics and value of denim material.

For boron doping on n-type silicon wafer, around $1,000^{\circ}C$ doping temperature is required, because of the relatively low solubility of boron in a crystalline silicon comparing to the phosphorus case. Boron doping by fiber laser annealing and lamp furnace heat treatment were carried out for the uniformly deposited p-a-Si:H layer. Since the uniformly deposited p-a-Si:H layer by cluster is highly needed to be doped with high temperature heat treatment. Amorphous silicon layer absorption range for fiber laser did not match well to be directly annealed. To improve the annealing effect, we introduce additional lamp furnace heat treatment. For p-a-Si:H layer with the ratio of $SiH_4:B_2H_6:H_2$=30:30:120, at $200^{\circ}C$, 50 W power, 0.2 Torr for 30 min. $20\;mm\;{\times}\;20\;mm$ size fiber laser cut wafers were activated by Q-switched fiber laser (1,064 nm) with different sets of power levels and periods, and for the lamp furnace annealing, $980^{\circ}C$ for 30 min heat treatment were implemented. To make the sheet resistance expectable and uniform as important processes for the $p^+$ layer on a polished n-type silicon wafer of (100) plane, the Q-switched fiber laser used. In consequence of comparing the results of lifetime measurement and sheet resistance relation, the fiber laser treatment showed the trade-offs between the lifetime and the sheet resistance as $100\;{\omega}/sq.$ and $11.8\;{\mu}s$ vs. $17\;{\omega}/sq.$ and $8.2\;{\mu}s$. Diode level device was made to confirm the electrical properties of these experimental results by measuring C-V(-F), I-V(-T) characteristics. Uniform and expectable boron heavy doped layers by fiber laser and lamp furnace are not only basic and essential conditions for the n-type crystalline silicon solar cell fabrication processes, but also the controllable doping concentration and depth can be established according to the deposition conditions of layers.

Expression of woman characters in fusion traditional dramas plays a role of making the progress of dramas not bigoted and new. Especially, woman characters have a high weight as a heroine by an increase in their image in fusion traditional dramas. Expression of characters harmonizing modern with tradition has also given a help in reflecting a trend of the present times. Hair style and face makeup of woman characters in fusion traditional dramas are in the process of fusionization getting an effect from postmodernism. They are expressing the hair style of symbolization modern elements of hair style to traditional hair styles. They also expressed a neutral image with faded hair styles in the shaggy cut style and dye of neoplaticism. Neo-hippie style was changed into the style of naturalism and nationalism and the hair style braided in various branches as the one of Indians was changed into a primitive and national feature. It is producing a new style by permitting even a long-hair permanent wave hair style. Expression of straight hair style, a long-hair shaggy & bulging wave style and a hair style of neoplaticism, was distinguished. In the side of face makeup, they expressed its luxurious and splendid style by attaching great importance to its luster and are exposing images of characters by a smoky makeup emphasizing eye lines. Their face makeup was almost never separated from present dramas as using pearl shadow in a glossy lips makeup and color, which made it possible to express it more dramatically in fusion traditional dramas than in present dramas. In the event of the makeup element of fusion traditional dramas permitting diversity, the character makeup of fusion traditional dramas made a foundation to show people diverse elements of makeup by mix & match a present elements and past elements of historical research, which made it possible to express a unique makeup or a special makeup. Diverse makeup expressions were limited by reflection of illumination even in the existing videos. Therefore, 'Fusion' made it possible to express it more freely in fusion traditional dramas than in present dramas.

This study examines how the concept of gender fluidity-viewing gender identity as a fluid and wide spectrum-is represented in modern knit fashion collections. The period spring/summer 2017-fall/winter 2021, when gender-related fashion keywords started attracting attention, was limited to the last five years, and the results of a case analysis focused on a total of 357 knit fashion photos are as follows. First, the androgynous compromise through the mixing of heterogeneous elements appears as a mix-and-match style due to the patchwork of heterogeneous materials and forms that borrow or share masculinity and femininity. Second, it was confirmed that the dismantling exaggeration caused by the destruction of the size and form of clothes was an avant-garde image that exaggerated the size or length of clothes or destroyed ideas and forms. Third, the exposed sensuality caused by the deformation of the fluid knitting technique was shown in the form of proudly expressing sexuality by exposing the body either using the cut-out technique or through the loose texture of the knit. Knit fashion can highlight decorative effects using handcrafted techniques and express a detailed or coarse sense of organization depending on the density. In addition, since it is possible to create a complex image by juxtaposing and mixing various knit structures, it was confirmed that it is a suitable material for expressing gender fluidity flowing between men and women in fashion.

This is a basic study of the two remaining armors (artifacts number K2366, K2368) from the late Joseon dynasty that is part of the Korean costume collection, which is preserved in the Mission Museum of Saint Ottilien in Germany. The armor No. 1 (artifacts number K2366) is a coat-styled armor with brass studs. It has a U-shaped neckline with the non-overlapping collars and sleeve straight-lined inseam. The armor No. 1 has the Mu to the sides and is not back slit. Both its inner and outer material are padded with cotton. Leather mails are attached on the inner lining, and studs are attached on the outer lining to match the leather mails. For this reason, the armor No. 1 can be named MyeonPiGab (brass studded armor consisting of a cotton coat with internal leather mails). The outer material is faded to have the natural white, or antique white look and the patterns on it are indigo blue. The inner material is blue, but the original color is unknown since it is faded. The lotus blossoms and vine patterns are dyed on the surface of the outer material and a name is written on the inner material. The armor No. 1 was worn between the late 17th century and the 19th century. It is estimated that it was worn by military officers who were above the mid-rank in the end of the Joseon dynasty. The armor No. 2 (artifacts number K2368) is a coat-styled armor with brass studs and a low-cut U-shaped neckline. The armor No. 2 has a slit on the left armpit and a string around it. Studs are evenly attached on the armor. The iron mails are attached to the left chest area on its inner lining. It seems that it was designed with both formality and functionality in mind. The outer material is red flannel, the inner material is blue satin and the pads are cheesecloth. The side of its collars, cuffs, front lines, sidelines, back slit, and bottom lines are trimmed with fur. There are armors called "JeonCheolGap (brass studded armor consisting of a felt coat with internal iron mails)," which is similar to the armor No. 2, however, the similarities are limited because they are not made of the same material nor do they follow the same principle of nomenclature.

$^{64}Cu$-labeled diacetyl-bis($N^4$-methylthiosemicarbazone) is a promising agent for internal radiation therapy and imaging of hypoxic tissues. In the study, we confirmed hypoxia regions in VX2 tumor implanted rabbits with injection $^{64}Cu$-ATSM and $^{18}F$-FDG using positron emission tomography (PET)/computed tomography (CT). PET images with $^{18}F$-FDG and $^{64}Cu$-ATSM were obtained for 40 min by dynamic scan and additional delayed PET images of $^{64}Cu$-ATSM the acquired up to 48 hours. Correlation between intratumoral $O_2$ level and $^{64}Cu$-ATSM PET image was analyzed. $^{64}Cu$-ATSM and $^{18}F$-FDG were intravenously co-injected and the tumor was dissected and cut into slices for a dual-tracer autoradiographic analysis. In the PET imaging, $^{64}Cu$-ATSM in VX2 tumors displayed a specific uptake in hypoxic region for48 h. The uptake pattern of $^{64}Cu$-ATSM in VX2 tumor at 24 and 48 h did not match to the $^{18}F$-FDG. Through ROI analysis, in the early phase (dynamic scan), $^{18}F$-FDG has positive correlation with $^{64}Cu$-ATSM but late phase (24 and 48 h) of the $^{64}Cu$-ATSM showed negative correlation with $^{18}F$-FDG. High uptake of $^{64}Cu$-ATSM in hypoxic region was responded with significant decrease of oxygen pressure, which confirmed by $^{64}Cu$-ATSM PET imaging and autoradiographic analysis. In conclusion, $^{64}Cu$-ATSM can utilize for specific targeting of hypoxic region in tumor, and discrimination between necrotic- and viable hypoxic tissue.

2003년부터 2004년 평창 지역의 브로콜리 포장에서 새로운 병해가 발견되었다. 유묘 감염이 되었을 때 떡잎의 주위로부터 검게 변색되기 시작하여 결국 떡잎이 떨어지고 유묘는 죽었다. 성체에서는 잎 가장자리로부터 엽맥을 타고 진전되어 V 자 또는 U 자형의 노란색 병반을 형성하였다. YDC 배지에서 병원세균을 순수 분리하였을 때 Xanthomonas 속 세균의 전형적인 특정인 노란색 색소를 띤 세균이 형성되었다. 분리된 세균을 $10^8 cfu/ml$로 현탁 한후 3 주 동안 자란 브로콜리, 양배추, 배추, 케일, 무에 가위 접종하여 병원성을 확인하였다. 지방산 조성 및 함량, 다양한 탄소원 이용정도 및 16S rDNA 염기서열를 이용하여 분리세균 SL4797 과 SL4800 을 대조균주 X. campestris pv. campestris NCPPB528 과 비교하였을 때 매우 유사하였다. 이 논문은 국내에서 브로콜리의 검은썩음병 최초 보고이다.

서론 : 핵의학에 있어서 컴퓨터의 발전은 질적인 향상뿐 아니라 양적으로도 성장하고 있다. 다양한 소프트웨어를 사용하여 핵의학과 업무에 적용한다면 양질의 영상을 얻고 단순작업의 시간을 줄일 수 있을 것이다. 핵의학과 업무에 있어 컴퓨터를 이용한 processing에 할애하는 시간은 상당하여, 이 시간을 줄이는 방법으로 Macro라는 프로그램을 적용하기로 하였고, 단순 반복 작업이 많은 Brain SPECT SPM processing과 Brain SPECT PACS verify processing에 적용해 보기로 하였다. 실험재료 및 방법 : Brain SPECT에서 SPM processing과 작업 건수가 많은 PACS 작업 두 가지를 대상으로 하였다. SPM은 Brain의 Neuroimaging data를 분석하기 위한 소프트웨어 패키지로서 그룹간의 정량적인 분석을 목적으로 하고, Realignment, Normalization, Smoothing, Mapping 등의 복잡한 과정을 거쳐 결과를 만들어낸다. 이 과정을 Macro Program를 이용해서 간단하게 코딩하는 작업을 거쳐 만들어 보았다. PACS verify작업은 PACS로 보낸 영상을 간단하게 Color mapping, Gray scale 조정, 복사, 잘라 붙이는 과정으로 이루어지는데, 이를 Macro Program을 이용하여 직접 마우스 좌표를 입력하였다. 수작업으로 했을 때와 Macro Program을 활용했을 때 결과물을 만드는 시간을 기록하여 2007년 검사건수에 대입하여 결과를 도출하였다. 결과 : 2007년 SPM 검사 건수는 115건, PACS 작업 건수는 Diamox 검사 기준으로 834건이었다. SPM을 수작업은 숙련도에 따라 10분에서 15분 소요되었고, Macro를 사용시 5분 30초가 소요되었다. 검사 건수에 대입하여 년 평균 시간을 산출하면 SPM을 수작업으로 했을 시 숙련도에 따라 1150~1725분(19~29시간)이 소요되었고, Macro 사용 시에는 632분(10.5 시간)이 걸렸다. PACS는 수작업 시 2~3분이 걸렸으며, Macro를 사용 시에는 45초가 걸렸다. 이를 검사 건수에 대입하면 수작업 시 1668~2502분(28~42시간)이 걸렸고, Macro 사용시 625분(10시간)이 소요되어서 1043~1877분(17~31)시간이 절약 되었다. 결과적으로, SPM에 있어서 45~63%, PACS 작업에 있어서는 62~75%, 2007년 기준으로 전체 Brain SPECT Processing에서 55~70% 정도의 시간 절약 효과를 볼 수 있었다. 결론 : 2007년 검사 건수 기준으로 Macro 프로그램 사용시 상당한 시간절약 효과를 가져왔고 아무리 적은 시간이 걸리는 작업이라도 건수에 따라 많은 시간을 줄일 수 있다는 것을 확인하였다. 이는 검사실 근무자에게 검사하는 환자에게 더욱 집중할 수 있는 시간적 여유를 주어 안전사고 발생률을 더욱 줄일 수 있을 것이다. 그리고, 논문을 통해서 알 수 있는 것처럼, Brain SPECT 프로세싱뿐만 아니라 다른 다양한 분야의 단순반복 업무에 매크로를 활용함으로써 얻을 수 있는 시간적 이득과 작업 효율성은 상당할 것이라 생각되어진다.
