  • This study was performed to investigate the change in the chemical components of red pepper powder using different packaging materials and various storage conditions. Red pepper powders with 11 and 15% initial moisture content were packed with five different materials and stored at different temperatures (0, 20, and 30 C) for a one year period. Over the storage period, each combination was periodically sampled, and examined for composition changes. The five packaging materials were: linear low density polyethylene(LLDPE), nylon/LLDPE(Ny/LLDPE), saran coated ethylene vinyl acetate copolymer/linear low density polyethylene(B650), nylon/Tie/nylon/ethylene-vinyl alcohol copolymer/nylon/Tie/LLDPE(RDX-2787) and oriented polypropylene/alumimum/LLDPE(OPP/Al/LLDPE), and the three storage conditions were (28.3${\pm}$1.0)$^{\circ}C$ with (15.5${\pm}$2.8)% relative humidity, (18.6${\pm}$0.5)$^{\circ}C$ with (46.6${\pm}$4.9)% RH, and (0${\pm}$2)$^{\circ}C$ with (80${\pm}$10)% RH, respectively. The moisture contents of all samples changed according to the relative storage humidity, except those of the samples packed with OPP/Al/LLDPE, which remained constant throughout the storage period. The capsaicinoids content of the red pepper powder did not change significantly for 6 months, but gradually decreased after that until about 85% of the original amount remained at the final stage of storage. The ASTA color values of all samples decreased gradually throughout the storage period. The higher the storage temperature, the more severe the deterioration. The color deterioration seemed greatly related to the existence of oxygen, as the deterioration was especially severe in the samples packed with LLDPE and B650, where the oxygen transmission rate were highest among the five packaging materials.

  • This study examined how Ji-Won Park(Yeonam) created the eaning of things based on the epic of self and how his travel experience manifested on the epic of self. First of all, the author examined that how Yeonam interpreted the meaning of things based on his own reflection using the examples of "The Golden Arbor" and "Baeki-Sukje." As a result, the author found that Yeonam focused on the material value of "the Golden Arbor" rather than the reason of creation of "The Golden Arbor." Yeonam also used "Baeki-Sukje" as an ironic representation rather than the original meaning of loyalty and integrity. Second, it helped to present personal self epic since travel experience and the atmosphere of the travel journey could reduce the pressure from the epic of society on individuals. For instance, when Ji-Won Park (Yeonman) traveled the China (the country of Chung) where society promoted public welfare, Yeonman was able to express himself freely which showed utilitarian over justice. Finally, the author talked about how a book of travels can be used for the case of literature therapy since "Yeulhailgi" was written by Yeonam while he was traveling. The author indicated that it might be useful for the patients to write own travel journey since the therapist could analyze the mind of patients by the epic of self. In addition, using a book of travels also can be valuable for the patients since the therapist could analyze the condition of patients as well as help patients see through themselves while reading a book of travels.

  • The greater demand for electricity and the available capacity within safety margins in some operating NPPs are prompting nuclear utilities to request license modification to enable operation at a higher power level, beyond their original license provisions. Such plant modifications require an in-depth safety analysis to evaluate the possible safety impact. The analysis must consider the thermo hydraulic, radiological and structural aspects, and the plant behavior, while taking into account the capability of the structures, systems and components, and the reactor protection and safeguard systems set points. The purpose of this paper is to introduce international experiences and approaches for implementation of power uprates related to the reactor thermal power of nuclear power plants. The paper is intended to give the reader a general overview of the major processes, work products, issues, challenges, events, and experiences in the power uprates program. The process of increasing the licensed power level of a nuclear power plants is called a power uprate. One way of increasing the thermal output from a reactor is to increase the amount of fissile material in use. It is also possible to increase the core power by increasing the performance of the high power bundles. Safety margins can be maintained by either using fuels with a higher performance, or through the use of improved methods of analysis to demonstrate that the required margins are retained even at the higher power levels. The paper will review all types of power uprates, from small to large, and across various reactor types, including light and heavy water, pressurized, and boiling water reactors. Generally, however, the content of the report focuses on power uprates of the stretch and extended type. The International Atomic Energy Agency (IAEA) is developing a technical guideline on power uprates and side effects of power uprates in nuclear power plants.

  • This article is concerned about the symbolic meaning of the transvestism Renaissance perspective through analysis of Triumph Over Persecution work and The Merchant of Venice, and Jealous Ioan Tornese. The transvestism is frequently present in the comedies of the golden age. A woman author Maria de Zayas has a special interest in female identity with critical and defying view. Also the subject of the transvestism in Spanish literature originated in Italian tradition. In Italian literature, there were two types of disguised women, who urge for love and warrior-heroine(amazon). Both types are also listed in Spanish literature. The dress-crossing heroine of Triumph Over Persecution displays a type of heroine, who corrects a male prejudice and reset a harmonious order. Shakespeare is also one of the Renaissance writers under the influence of the Italian Renaissance novel. Heroine of Merchant of Venice symbolizes a triumphant challenge against the blocks of the patriarchal system. In spite of the social system blocks, cross-dressing women may receive in the patriarchal scenes without problems. Based on the notion of paradox and irony, the Italian novel reflects popular psychology of the time when the link between the internal identity and social outside puts into question. The cross-dressing Torneses' wife, symbolizes the mockery or renaissance deception. Their deception emphasis on an ironic way in the point view of inhuman man who consider women material belongs to the man without any free-will. The costume of the characters make it possible to change their original identity into the other. From this point of view, we can say that the transvestism in these works could be interpreted in two ways: first, the destruction of the traditional categories of women's identity and second, the burlesque contempt on the patriarchal renaissance society.

  • 남원 광한루는 본루, 익루, 월랑 등 세 부분으로 구성된 누각이다. 각 부분이 추가되는 형식으로 증축된 것이라고 알려진 광한루의 건축시기를 조사하기 위해 2001~2002년 수리 공사 중에 교체되는 본루, 익루, 월랑의 목부재와 적심재에 대하여 연륜연대를 측정하였다. 본루의 주두, 도리, 적심, 그리고 익루의 중도리, 귀틀 부재가 1624년 늦가을부터 1626년 초봄사이에 벌채된 것으로 밝혀져 본루와 익루의 건축을 위해 같은 기간에 벌채가 이루어졌음을 알 수 있었다. 이는 익루가 1626년 본루의 중건당시 함께 지어졌다는 증거이다. 1879년에 증축된 것으로 알려진 월랑은 연륜연대 측정결과 1881년~1882년에 본루와 익루의 대규모 수리와 함께 건축된 것으로 해석되었다. 그밖에 본루의 사래와 도리받침, 익루의 추녀가 1855년에 벌채된 것으로 나와 1855년에 중수가 있었다는 역사기록과 일치하였다.

  • The paper focuses on bending analysis of the functionally graded (FG) plates with arbitrary shapes and boundary conditions. The material property of FG plates is modelled by using the power law distribution. Based on the first order shear deformation plate theory (FSDT), the governing equations as well as boundary conditions are formulated and obtained by using the principle of virtual work. The coupled Boundary Element-Radial Basis Function (BE-RBF) method is established to solve the complex FG plates. The proposed methodology is developed by applying the concept of the analog equation method (AEM). According to the AEM, the original governing differential equations are replaced by three Poisson equations with fictitious sources under the same boundary conditions. Then, the fictitious sources are established by the application of a technique based on the boundary element method and approximated by using the radial basis functions. The solution of the actual problem is attained from the known integral representations of the potential problem. Therefore, the kernels of the boundary integral equations are conveniently evaluated and readily determined, so that the complex FG plates can be easily computed. The reliability of the proposed method is evaluated by comparing the present results with those from analytical solutions. The effects of the power index, the length to thickness ratio and the modulus ratio on the bending responses are investigated. Finally, many interesting features and results obtained from the analysis of the FG plates with arbitrary shapes and boundary conditions are demonstrated.

  • The emergence of environmental and social issues has led to global discussions for the realization of sustainable development. The purpose of this study is to propose a method of sustainable fashion design using waste Hanbok, focusing on men's Hanbok with cultural values. The study utilizes literature research and fashion design development. From the literature study, reform was judged to be a higher concept encompassing reduction, recycling, and upcycling. Reduction is a design method through removal, and recycling design transforms from its original form into a completely different product. Upcycling design focuses on improvement and change in functionality. Accordingly, nine redesigns using men's Hanbok were developed from which three were produced. Consequently, the reduction design demonstrated a small range of variation without changing the item, and cultural sustainability was confirmed through the design that removed the components and recombined the Hanbok. Second, recycling redesign can be reconstituted into a different item. Third, upcycling enables various designs through module assembly, which prolongs the lifespan of the product and confirms its value as a raw material for waste Hanbok. This study is meaningful in realizing sustainable fashion and suggesting practical measures for the sustainability of Korean traditional culture and creative fashion design planning.

  • Gindai (Pristipomoides zonatus) is one of six snappers in a management complex called the Deep 7 of the Hawaiian Islands. Little is known about its life history and a preliminary analysis of otolith thin sections indicated the species may exhibit moderate growth with a lifespan approaching 40 years. Preliminary age estimates from the previous study were reinvestigated using the same otolith sections in an attempt to validate those ages with bomb radiocarbon (14C) dating. From the misalignment of birth years for the otolith 14C measurements with regional references - the post-peak bomb 14C decline period - it was concluded that previous ages were inflated from overcounting of the earliest growth zone structure in otolith sections. The oldest gindai was re-aged to 26 years once the age reading was adjusted for early overcounting, 13 years younger than the original estimate of 39 years for this fish. In general, the earliest otolith growth of gindai was massive and complicated by numerous subannual checks. The approach of lumping the early growth structures was supported by the alignment of 14C measurements from otolith core material (first year of growth). The result was greater consistency of calculated birthdates with the 14C decline reference, along with minor offsets that may indicate age estimation was imprecise by a few years for some individuals. The revised von Bertalanffy growth function applied to the validated age-at-length estimates revealed more rapid growth (k = 0.378 cf. 0.113) and a lifespan of approximately 30 years. The findings presented here are a case study of how the bomb 14C decline period can be used as a tool in the refinement of age reading protocols.

  • The purpose of this study is to contribute to the role of lines in creative design development by analyzing the expression types and aesthetic characteristics of modern fashion using geometric formativeness of symmography. A literature study was conducted of works since 2009 to examine the general consideration of lines together with analysis of the concept and characteristics of symmography in the formative arts field, and to analyze the expression types and aesthetic characteristics of modern fashion design using the formativeness of symmography. The infinite sense of formativeness and original expression of symmography are used in formative arts such as space design, installation art, and industrial design. Expression types of modern fashion design using geometric formativeness of symmography can be classified into the following three types: two-dimensional graphic pattern, relief surface, and three-dimensional spatial. First, the two-dimensional graphic pattern type forms an optical pattern, providing individuality and visual interest to the textile design. Second, the relief surface type expresses the plane in various ways, so that the thickness changes according to how lines overlap. Third, the three-dimensional spatial type expands the boundaries of clothing and creates a fantastic spatial beauty. Next, the aesthetic formativeness of fashion design using symmography can be classified into repetitive rhythmicity, geometric self-similarity, and optical spatiality. Symmography enables a myriad of geometric patterns to be developed depending on material, color, and the designer's imagination, and helps inspire a variety of designs in fashion that sculpt a three-dimensional human body.
