The purpose of this study was to use the Kano model to compare and analyze the educational service quality attributes of domestic and foreign culinary arts schools. For this purpose, a questionnaire-based survey was completed by 312 students who were studying in domestic and foreign culinary schools. The results of the study indicated that 23 of the total 25 attributes were significantly different between domestic and foreign culinary arts school.; the "minium 4 hour-kitchen class" and "mandatory internship program" were classified into "indifferent quality" for domestic schools and a "must-be quality" for foreign schools; "well-organized internship guidebook", "kitchen class limited to 20 students", "introducing the latest food or restaurant trends", "library with the latest publications related to major", "objective instructor's evaluation", "detailed instructor's evaluation", "instructor's field experience", and "decent communication skills on the part of the instructor" attributes were classified into "attractive quality" for domestic schools and "must-be quality" for foreign schools; and "kitchen classes operated by block system", and "foreign instructors for each ethnic cuisine" attributes were classified into "indifferent" and "attractive quality" for both domestic and foreign schools, respectively. Also, according to the Better and Worse quotient designed by Timko, there were more attributes for domestic school than for foreign school that scored over 0.5 in the Better category and fewer attributes for domestic than the foreign scored over 0.5 in the Worse category. The results also indicate that, students in foreign schools receive an educational service of better quality than students in a domestic school. As a result, this research suggests significant implications to develop culinary educational services.

RSA 암호 시스템은 IC카드, 모바일 시스템 및 WPKI, 전자화폐, SET, SSL 시스템 등에 많이 사용된다. RSA는 모듈러 지수승 연산을 통하여 수행되며, Montgomery 곱셈기를 사용하는 것이 효율적이라고 알려져 있다. Montgomery 곱셈기에서 임계 경로 지연 시간(Critical Path Delay)은 세 피연산자의 덧셈에 의존하고 캐리 전파를 효율적으로 처리하는 문제는 Montgomery 곱셈기의 효율성에 큰 영향을 미친다. 최근 캐리 전파를 제거하는 방법으로 캐리 저장 덧셈기(Carry Save Adder, CSA)를 사용하는 연구가 계속 되고 있다. McIvor외 세 명은 지수승 연산에 최적인 CSA 3단계로 구성된 Montgomery 곱셈기와 CSA 2단계로 구성된 Montgomery 곱셈기를 제안했다. 시간 복잡도 측면에서 후자는 전자에 비해 효율적이다. 본 논문에서는 후자보다 빠른 연산을 수행하기 위해 캐리 전파 제거 특성을 가진 이진 부호 자리(Signed-Digit SD) 수 체계를 사용한다. 두 이진 SD 수의 덧셈을 수행하는 잉여 이진 덧셈기(Redundant Binary Adder, RBA)를 새로 제안하고 Montgomery 곱셈기에 적용한다. 기존의 RBA에서 사용하는 이진 SD 덧셈 규칙 대신 새로운 덧셈 규칙을 제안하고 삼성 STD130 $0.18{\mu}m$ 1.8V 표준 셀 라이브러리에서 지원하는 게이트들을 사용하여 설계하고 시뮬레이션 하였다. 그 결과 McIvor의 2 방법과 기존의 RBA보다 최소 12.46%의 속도 향상을 보였다.

Effective climate protection is a most important tasks of our time. The BIPV is one of the most interesting and promisingly possibilities of an active use of solar energy at the building. In this study it was analyzed by the case study the function of the requirement of the BIPV-module as building material and this architectural characteristic according to the kind of the module. Therefore the goal of this study is to get securing the application information of BIPV as windowpane. BIPV modules are manufactured in the form of G/G. In the case of the crystal type the Transparent and the light Transmission is to be adjusted by the spacer attitude of the cell. Although this type could not be optimal for light effect of indoors because of the inequality of shade, the moving shade play makes a dramatic Roomimage by the run of sun. The application of this type would be for canopy, window or roof in the corridor or resounds. With amorphous the type it is to be manufactured simply largely laminar, and thus that will shorten building process. There is a relatively good economy to use and to the window system easily. After the production technology is easy the transparency of the modules to adjust, and the module shows to a high degree constant characteristics of light permeability and transparency. Without mottle of module shade is good the use for the window or roof glazing of office, library, classroom, etc. to adapt. The BIPV modules took generally speaking a function as building material to the daylight use, shading, isolation and also to the sight. That means that BIPV modules have as multifunctional system to sustainable architecture good successes and they are at the same time as Design element for architecture effectively.

The big gap between efficacy of population level prevention and expectations due to heterogeneity and complexity of cancer etiologic factors calls for selective yet personalized interventions based on effective risk assessment. This paper documents our research protocol aimed at refining and validating a two-stage and web-based cancer risk assessment tool, from a tentative one in use by an ongoing project, capable of identifying individuals at elevated risk for one or more types of the 80% leading cancers in rural China with adequate sensitivity and specificity and featuring low cost, easy application and cultural and technical sensitivity for farmers and village doctors. The protocol adopted a modified population-based case control design using 72, 000 non-patients as controls, 2, 200 cancer patients as cases, and another 600 patients as cases for external validation. Factors taken into account comprised 8 domains including diet and nutrition, risk behaviors, family history, precancerous diseases, related medical procedures, exposure to environment hazards, mood and feelings, physical activities and anthropologic and biologic factors. Modeling stresses explored various methodologies like empirical analysis, logistic regression, neuro-network analysis, decision theory and both internal and external validation using concordance statistics, predictive values, etc..

This systematic review focused on the efficacy of topical products in reducing temporomandibular joint disorder (TMD)-associated pain, in comparison to placebo or control interventions. The EMBASE, Web of Science, Cochrane Library, and MEDLINE via PubMed databases were searched for randomized controlled trials (RCTs) using topical interventions in adults diagnosed with TMD. The pain intensity was the primary outcome, and other clinical findings were the secondary outcomes. The risk of bias was evaluated according to the Cochrane's handbook. The search up to February 7, 2020 identified a total of 496 unduplicated references. Nine RCTs with 355 adult patients diagnosed with TMD were included. The meta-analysis did not show a significant reduction in baseline pain intensity in the nonsteroidal anti-inflammatory drug (NSAIDs) group, when compared to the placebo group (P = 0.288). One study demonstrated a statistically significant pain score decrease for Theraflex-TMJ compared to placebo after 10 d of treatment (P = 0.003) and follow-up, 5 d after the last application (P = 0.027). Ping On reduced pain at 4 weeks of application (P < 0.001) but not after 7 d of application (P = 0.136). In one study, cannabidiol (CBD) significantly improved the pain intensity compared to placebo (P < 0.001). However, no differences were found with capsaicin in the two studies (P = 0.465). Evidence was of low quality because the studies were considered as having an unclear or a high risk of bias and a small number of studies were analyzed. The evidence is not sufficient to support the use of topical NSAIDs and capsaicin, and limited evidence was found for Threraflex-TMJ, bee venom, Ping On, and CBD, with only one study reporting for each. Additional studies are recommended to validate these results.

Background: Chronic neuropathic pain (NP) presents therapeutic challenges. Interest in the use of cannabis-based medications has outpaced the knowledge of its efficacy and safety in treating NP. The objective of this review was to evaluate the effectiveness of cannabis-based medications in individuals with chronic NP. Methods: Randomized placebo-controlled trials using tetrahydrocannabinol (THC), cannabidiol (CBD), cannabidivarin (CBDV), or synthetic cannabinoids for NP treatment were included. The MEDLINE, Cochrane Library, EMBASE, and Web of Science databases were examined. The primary outcome was the NP intensity. The risk of bias analysis was based on the Cochrane handbook. Results: The search of databases up to 2/1/2021 yielded 379 records with 17 RCTs included (861 patients with NP). Meta-analysis showed that there was a significant reduction in pain intensity for THC/CBD by -6.624 units (P < .001), THC by -8.681 units (P < .001), and dronabinol by -6.0 units (P = .008) compared to placebo on a 0-100 scale. CBD, CBDV, and CT-3 showed no significant differences. Patients taking THC/CBD were 1.756 times more likely to achieve a 30% reduction in pain (P = .008) and 1.422 times more likely to achieve a 50% reduction (P = .37) than placebo. Patients receiving THC had a 21% higher improvement in pain intensity (P = .005) and were 1.855 times more likely to achieve a 30% reduction in pain than placebo (P < .001). Conclusion: Although THC and THC/CBD interventions provided a significant improvement in pain intensity and were more likely to provide a 30% reduction in pain, the evidence was of moderate-to-low quality. Further research is needed for CBD, dronabinol, CT-3, and CBDV.

To isolate the microsatellites from the chromosomal DNA of the Korean cattle (Hanwoo) and to use those for the genetic selection, four bacteriophage genomic libraries containing the chromosomal DNA of six Hanwoo steers showing the differences in meat quality and quantity were used. Screening of the genomic libraries using $^{32}P-radiolabeled 5'-({CA})_{12}-3$nucleotide as a probe, resulted in isolation of about 3,000 positive candidate bacteriophage clones that contain $(CA)_n$-type dinucleotide microsatellites. After confirming the presence of microsatellite in each positive candidate clone by Southern blot analysis, the DNA fragments that include microsatellite and flanking sequences possessing less than 2 kb in size, were subcloned into plasmid vector. Results from the analysis of microsatellite length polymorphism, using twenty-two PCR primers designed from flanking region of each microsatellite DNA, demonstrated that 208 and 210 alleles of HW-YU-MS#3 were closely related to the economic traits such as marbling score, daily gain, backfat thickness and M. longissimus dorsi area in Hanwoo. Interestingly, HW-YU-MS#3 microsatellite was localized in bovine chromosome 17 on which QTLs related to regulation of the body fat content and muscle ypertrophy locus are previously known to exist. Taken together, the results from the present study suggest the possible use of the two alleles as a DNA marker related to economic trait to select the Hanwoo in the future.
