  • Fashion cultural products represents cultural trend, and they are produced a lot in Korea to express the Korean culture and style. They are also tools that embody images of Korea. This study mainly focuses on the Korean traditional-patterned ornaments as fashion cultural products. Therefore, this study aims at developing a framework of consumers' attitudes and consumption behaviors about Korean traditional-patterned ornaments, examining how the characteristics are changed according to shopping orientation. For this purpose, a quantitative survey was carried out using 455 questionnaires from women in their 20s and over. The data were analyzed using frequency analysis, factor analysis, t-test, ANOVA, cluster analysis, and $x^2$-test. Findings of this study were as follows. First, half of the respondents were found to possess Korean traditional-patterned ornaments. However, consumers had positive attitudes and tend to purchase them for their own use rather than gifts, demonstrating that the potential for the market is large enough. Second, in accordance with their shopping orientation, consumers were sub-divided into four groups: trend/brand oriented, practicality/pleasure oriented, convenience oriented, and passive shoppers. The trend/brand oriented group showed highest levels of preference regarding purchase intentions of Korean traditional-patterned ornaments. This group also showed the strongest purchasing power on fashion items among the four groups. Third, this study presented animal, plant, geometric and abstract patterns to the respondents to examine their attitudes. It was found that consumers prefered plant-patterned ornaments rather than the others, demonstrating that they have stronger preference and purchase intention toward ornaments with more natural images.

  • This study was to assess the effects of sowing mixed legume forage and applying fermented cattle manure on the productivity and feed value of whole crop wheat (WCW) as a representative of winter crops and also to estimate feeding capacity of Korean native cattle (Hanwoo) per unit area by defining optimal application levels of cattle manure for more fertile soil and manure recycling for the purpose of reduced environmental pollution and efficient production of organic forage contributable to production of organic animal products. Sowing mixed legume forage significantly (p<0.05) increased yields of dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) for WCW compared to WCW alone sowing, but there were no differences between mixed sowing treatments. The yields of DM, CP and TDN were significantly (p<0.05) higher in 100~150 kg N/ha. The CP and acid detergent fiber (ADF) contents were highest in mixed sowing with hairy vetch, followed by sowing mixed forage pea and WCW alone (p<0.05). There were no differences in CP among cattle manure application levels. As nitrogen application level increased, ADF content increased (p<0.05), but TDN content decreased (p<0.05). Feeding capacity of organic Hanwoo (head/ha) weighing 450 kg of body weight with 400 g of daily gain significantly (p<0.05) increased due to mixed sowing with legume forage, and with increasing application levels of fermented cattle manure, feeding capacity significantly (p<0.05) increased. The results indicated that mixed-sowing of WCW and legume forage not only reduced nitrogen application level of fermented cattle manure by over 50 kg per ha but also increased their feed value and productivity, and feeding capacity. This would be contributable to diversity of forage resources as well as production of organic animal product by creating low cost and high quality of forage.

  • The study of corrosion products generated by archaeological bronzes that have been buried for a long time can provide certain evidence that enables us to understand the natural corrosion process of bronze and helps us develop conservation and preservation methods. In the present study, the specimens taken from two bronze mirrors and three bronze swords were used to study the corrosion morphology and the related phenomena such as selective corrosion of ${\alpha}$ or ${\alpha}+{\delta}$ phases, decuprification, destannification, and secondary copper. Furthermore, corrosion development was discussed based on the ions distributed throughout the corrosion layers.

  • Software vulnerabilities represent security weaknesses in software systems that attackers exploit for malicious purposes, resulting in potential system compromise and data breaches. Despite the increasing prevalence of these vulnerabilities, manual repair efforts by security analysts remain time-consuming. The emergence of deep learning technologies has provided promising opportunities for automating software vulnerability repairs, but existing AIbased approaches still face challenges in effectively handling complex vulnerabilities. This paper explores the potential of large language models (LLMs) in addressing these limitations, examining their performance in code vulnerability repair tasks. It introduces the latest research on utilizing LLMs to enhance the efficiency and accuracy of fixing security bugs.

  • The purpose of this study was to investigate the changes of taste components in the boiled beef brisket soup stock and shank soup stock by varying pretreatment, boiling temperature and time. Free amino acids and nucleotides color and sensory evaluation in each samples were analyzed. The results were obtained as follows : 1. The amount of free amino acids in the brisket soup stock pretreated by soaking and blanching showed a tendency to increase in proportion to boiling time. The amount of glutamic acid in the brisket soup stock was much in order of soaking > blanching > roasting pretreatment. While the amount of glutamic acid in the boiled soup stock samples pretreated by soaking and blanching was much more at low temperature than at high temperature, the glutamic acid contents in the boiled soup stock pretreated by roasting were large at high temperature. The amount of glutamic acid in pretreated by soaked soup stock showed the highest and recorded 8.73 mg% at 6 hour-low temperature-boiling. 2. The amount of free amino acids in the shank soup stock did not show any regular tendency and had few changes in quantity by the methods of pretreatment. Each amount of glutamic acid in the shank soup stock pretreated by soaking and blanching was the highest, when boiled for 3 hours at high temperature. The samples pretreated by roasting showed the highest record 2.49 mg%, when boiled for 6 hours at high temperature, but could not recognize any regular tendency in the case of boiling at low temperature. 3. The amount of nucleotides in the brisket soup stock generally showed increase in proportion to boiling time. The amount of 5'-IMP extracted from the brisket soup stock was much in order of blanching > soaking > roaking pretreatment, but few differences between blanching and soaking soup stock samples. The amount of 5'-IMP extracted from soup stock samples pretreated by soaking and blanching was high at low-boiling and by roasting at high-boiling. Each amount of 5'-IMP extracted from soup stocks pretreated by soaking(BSL) and blanching(BBL) was the highest at 6 hour-low-boiling(37.06 mg%), and 5 hours(38.37 mg%) respectively. The amount of 5'in the soup stock pretreated by roasting(BRH) showed the highest records at 6 hour-high-boiling(10.85 mg%). 4. The amount of 5'-IMP extracted from the shank soup stock preteated by soaking and blanching showed a tendency to decrease after 3 hours boiling irrelative of boiling temperature. The amount of 5'in the shank soup stock was much in order of soaking > blanching > roasting pretreatment and showed high at the boiling of high temperature. In the sample pretreated by roasting it showed the highst records when boiled for 6 hours at high temperature(1.55 mg%). 5. The L Value of the brisket soup stock pretreared by roasting at high temperature(BRH) was the lowest and the b value of it was the highest of all the brisket samples boiled for 6 hours. No differences were found in the Value of L, a, and b in shank soup stock by the methods of pretreatment and boiling temperature. 6. The sensory scores in color and flavor of the brisket soup stock showd that BRH was higher than the other samples, and the preference in taste and overall was the highest in BSH while it was the lowest in BRH. The preference in the all sensory characteristics of SSH was higher than any other shank soup stock, but did not show any significant difference statistically.

  • This study was to test whether in vitro matured Hanwoo oocytes can be successfully cryopreserved by a new vitrification procedure using MVC method. For the vitrification, oocytes were pretreated in 10% ethylene glycol (EG10) for 5~10 min, exposed in EG30 for 30 sec, each oocyte was individually put on the inner wall of 0.25 $m\ell$ straw, and then straws were directly plunged into L$N_2$. Thawing was taken by 4-step procedures 〔1.0 M sucrose (MS), 0.5 MS, 0.25 MS, and 0.125 MS〕 at 37$^{\circ}C$. In vitro developmental capacity (survival, cleavage ($\geq$2-cell) and blastocyst rates) in vitrified group was no significant difference compared to that in other treatment groups (exposed; 100.0, 74.4, 32.3% and control; 100.0, 78.3, 36.3%): high mean percentage of oocytes (91.2%) was survived, 69.4% of them were cleaved and 27.9% of cleaved embryos were developed to blastocyst. Especially, after transfer of in vitro developed embryos in vitrified group, four of six recipient animals were pregnant and three of them were ongoing-pregnant by manual palpation at 250 days after transfer. This result demonstrates that MVC method is very appropriate freezing method for the Hanwoo in vitro matured oocytes and that ovum bank can be maintained efficiently by MVC cryopreservation method.

  • Recently, it becomes essential for firms or nations to forecast the future and identify emerging technologies in order to improve R&D efficiency and gain a competitive advantage. Particularly, the mobile communications industry is characterized by rapid advance and wide application of its technology and thus identifying emerging technologies is more important in the industry than in others. Nevertheless, few attempts have been made to explore its emerging technologies. Therefore, this research aims to develop a methodology to identify the future and emerging technologies especially for the industry and applied it to list top ten emerging technologies for 2020 in the industry. For this purpose, firstly, we focused the key issues in the future targeting 2020 and identified user needs relating to them. Then, candidates of emerging technologies were defined from a set of technologies to meet the needs, for which technological and economic feasibility is assessed to determine their priorities. Finally, the top ten most important technologies were selected and verified. This research is distinct from the previous studies in that it takes a market-pull approach instead of a technology-push approach. The research results are expected to provide valuable information to support strategy- and policy-makings in the mobile communications industry.

  • This article reviews recent developments in three-dimensional (3-D) magntotelluric (MT) imaging. The inversion of MT data is fundamentally ill-posed, and therefore the resultant solution is non-unique. A regularizing scheme must be involved to reduce the non-uniqueness while retaining certain a priori information in the solution. The standard approach to nonlinear inversion in geophysis has been the Gauss-Newton method, which solves a sequence of linearized inverse problems. When running to convergence, the algorithm minimizes an objective function over the space of models and in the sense produces an optimal solution of the inverse problem. The general usefulness of iterative, linearized inversion algorithms, however is greatly limited in 3-D MT applications by the requirement of computing the Jacobian(partial derivative, sensitivity) matrix of the forward problem. The difficulty may be relaxed using conjugate gradients(CG) methods. A linear CG technique is used to solve each step of Gauss-Newton iterations incompletely, while the method of nonlinear CG is applied directly to the minimization of the objective function. These CG techniques replace computation of jacobian matrix and solution of a large linear system with computations equivalent to only three forward problems per inversion iteration. Consequently, the algorithms are efficient in computational speed and memory requirement, making 3-D inversion feasible.

  • To investigate the feasibility of embryo transfer technology to promote productivity of cattle, 36 cows(18 Holstein, 18 Hanwoo) were superovulated. Fresh embryos were transferred to 25 recipients(14 Holstein, 11 Hanwoo), whereas frozen embryos were transferred to 17 recipients(10 Holstein, 7 Hanwoo). Two embryos were transferred at a time to 13 recipients(9 Holstein, 4 Hanwoo) to produce twin calves. 1. 75.0% of donor cattle were reacted to hormonal treatment far superovulation. 2. The rate of embryo recovery by non-surgical method for Holstein and Hanwoo was 90.4 and 95.8% in comparison with numbers of corpus luteum. 3. Of all the ova collected non-surgically, the rate of viable blastocyst was 66.4% and the rate of transferrable blastocysts was 48.6%. 4. The rate of embryo collection by one-catheter method was 75.0%. 5. The rate of pregnancy/delivery following embryo transfer with fresh embryos was 60.0%. 6. The rate of pregnancy/delivery following embryo transfer with frozen embryos was 35.3%. 7. In embryo transfer to produce twin calves, the rate of pregnancy/delivery was 28.6% with fresh embryos and 16.7% with frozen embryos.
