  • Background: Young male and female workers are over-represented in statistics concerning negative outcomes of poor work environment and risky work. Young workers often have low awareness of risk, a lack of safety training, and inadequate introduction to the work. The aim of this study was to identify the knowledge and experiences of pupils of vocational schools concerning potential work environment risks in their future work. Methods: The study design was a dual one, and included a questionnaire and focus group interviews. The study group consisted of 239 pupils from 10 upper secondary schools, who were graduating pupils in four vocational programs: the Industrial Technology Programme, the Restaurant Management and Food Programme, the Transport Programme, and the Handicraft Programme (in which students specialize in wood products). The upper secondary schools were located in the central region of Sweden. Results: The pupils had limited knowledge that employers must, by law, conduct risk analyses and prevent risks. Many felt that they themselves are mainly responsible for performing their tasks safely. Pupils in all programs mentioned acute risk as the greatest risk at work. The theoretical education about safety at work was provided in the $1^{st}$ year of the 3-year vocational programs. Conclusion: A systematic approach to pupils' training in work environment, which is a basis for a safe and healthy workplace, is lacking. The study findings indicate that pupils are offered knowledge far from that intended by laws and by state-of-the-art occupational health risk research.

  • Objectives: In this study, we evaluated the influence of different radiant exposures provided by single-peak and polywave light-curing units (LCUs) on the degree of conversion (DC) and the mechanical properties of resin cements. Materials and Methods: Six experimental groups were established for each cement (RelyX ARC, 3M ESPE; LuxaCore Dual, Ivoclar Vivadent; Variolink, DMG), according to the different radiant exposures (5, 10, and $20J/cm^2$) and two LCUs (single-peak and polywave). The specimens were made (7 mm in length ${\times}$ 2 mm in width ${\times}$ 1 mm in height) using silicone molds. After 24 hours of preparation, DC measurement was performed using Fourier transform infrared spectrometry. The same specimens were used for the evaluation of mechanical properties (flexural strength, FS; elastic modulus, E) by a three-point bending test. Data were assessed for normality, after which two-way analysis of variance (ANOVA) and post hoc Tukey's test were performed. Results: No properties of the Variolink cement were influenced by any of the considered experimental conditions. In the case of the RelyX ARC cement, DC was higher when polywave LCU was used; FS and E were not influenced by the conditions evaluated. The LuxaCore cement showed greater sensitivity to the different protocols. Conclusions: On the basis of these results, both the spectrum of light emitted and the radiant exposure used could affect the properties of resin cements. However, the influence was material-dependent.

  • Methyl gallate (MG) is a medicinal herbal product that is isolated from Paeonia lactiflora that inhibits cyclooxygenase-2 (COX-2) dependent phases of prostaglandin $D_2\;(PGD_2)$ generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner with an $IC_{50}$ values of $17.0\;{\mu}M$. This compound also found inhibited the COX-2-dependent conversion of the exogenous arachidonic acid to $PGD_2$ in a dose-dependent manner with an $IC_{50}$ values of $190\;{\mu}M$, using a COX enzyme assay kit. However, at concentrations up to $80\;{\mu}M$, MG did not inhibit COX-2 protein expression in BMMC, indicating that MG inhibits COX-2 activity directly. Furthermore, MG consistently inhibited the production of leukotriene $C_4\;(LTC_4)$ in a dose dependent manner, with an $IC_{50}$ value of $5.3\;{\mu}M$. These results demonstrate that MG has a dual cyclooxygenase-2/5-lipoxygenase inhibitory activity, which might provide the basis for novel anti-inflammatory drugs.

  • Objectives : The aim of this study is to summarise pattern-identification of shoulder pain based on the classics of oriental medicine, current literature and domestic papers. Methods : The materials selected were sourced from the classics of oriental medicine, current literature and domestic papers which contained data related to pattern-identification of shoulder pain. The pattern-identifications were compared to determine the similarities, and these were classified. Results : Thirty-five studies were reviewed, and thirty-seven pattern-identifications were collated. These were classified into the following groups: wind-cold-dampness group(n = 8), blood stasis group(n = 3), phlegm group(n = 7), dual deficiency of Qi and blood group(n = 4), deficiency cold group(n = 2), liver-kidney deficiency group(n = 1) and meridian-collateral group(n = 12). Conclusions : On the basis of the classification of pattern-identifications, two groups of pattern-identifications for shoulder pain were suggested. The first group included the pattern-identification associated with a disease-cause, which included the wind-cold-dampness pattern(風寒濕型), blood stasis pattern(瘀血型), phlegm pattern(痰飮型), Qi-blood deficiency pattern(氣血兩虛型), deficiency cold pattern(虛寒型), and liver-kidney deficiency pattern(肝腎虧損型). The second included the pattern-identification associated with the meridian-collateral, which included the hand greater Yin meridian pattern(手太陰經型), hand Yang brightness meridian pattern(手陽明經型), hand lesser Yin meridian pattern(手少陰經型), hand greater Yang meridian pattern(手太陽經型), hand reverting Yin meridian pattern(手厥陰經型), hand lesser Yang meridian pattern(手少陽經型), and foot greater Yang meridian pattern(足太陽經型).

  • Background: As elderly population has been increasing, pharmacists need to possess special knowledge and skills to provide enhanced pharmaceutical care for senior patients. Purpose: This study aims to systematically review on (1) the certified geriatric pharmacists (CGP) system, (2) the curriculum related to geriatric pharmacy education, and (3) the CGP's performance in terms of clinical, economic and humanistic outcomes in the U.S. Method: The information related to CGP system and curriculum was obtained through the official websites of 'American Society of Consultant Pharmacists', 'Commission for Certification in Geriatric Pharmacy' and the selected pharmacy school samples. Articles about on the outcomes of pharmacist-provided cognitive services including Medication Therapy Management were searched through PubMed. Results: To gain the CGP credential, pharmacists need 2-year experience as pharmacist in advance and take the CGP examination. This certification must be renewed every 5 year. Most pharmacy schools provide geriatric-related curriculum through didactic or pharmacy practice classes for pharmacy students and certificate or dual degree in gerontology are given on completion. Most previous outcomes research reported that pharmacists have played a role in yielding favorable results regarding clinical, economic and humanistic outcomes for nursing facilities, hospitals and community pharmacy settings. Conclusion: Considering the organized CGP certification system and concrete educational courses established the basis for pharmacists to exert their ability for senior patients of the U.S., it is suggested to build a geriatric pharmacist credential model for pharmacists to provide the increasing elderly patients with the requisite safe and effective pharmacy care in Korea.

  • THz 대역 전파흡수체를 구현하기 위해 split cut wire(SCW)와 배면 도체로 구성되는 단위 셀 구조를 제안하였다. 배면이 금속으로 단락된 유전체 기판 상에 SCW가 배열된 메타소재에서 SCW의 길이와 폭을 조절하여 THz 대역에서 완전 전파흡수체(5.5~6.0 THz에서 반사손실 -20 dB 이하)의 구현이 가능하였고, 인덕턴스-커패시턴스 (L-C) 공진기 회로이론으로 이를 설명하였다. 길이가 서로 다른 두 개의 SCW를 하나의 단위 셀 안에 같이 배치함으로써 두 개의 흡수 피크를 얻을 수 있었다. SCW 간의 간격이 넓어짐에 따라 두 번째 공진주파수는 거의 변화가 없지만 첫 번째 공진주파수는 저주파로 이동하면서 반사손실 값이 현저히 감소하는 경향이 나타났다.

  • Ochnaflavone is a medicinal herbal product isolated from Lonicera japonica that inhibits cyclooxygenase-2 (COX-2) dependent phases of prostaglandin $D_2(PGD_2)$ generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner with $IC_{50}$ values of $0.6{\mu}M$. Western blotting probed with specific anti-COX-2 antibodies showed that the decrease in quantity of the $PGD_2$ product was accompanied by a decrease in the COX-2 protein level. In addition, this compound consistently inhibited the production of leukotriene $C_4 (LTC_4)$ in a dose dependent manner, with an $IC_{50}$ value of $6.56 {\mu}M$. These results demonstrate that ochnaflavone has a dual cyclooxygenase-2/5-lipoxygenase inhibitory activity. Furthermore, this compound strongly inhibited degranulation reaction in a dose dependent manner, with an $IC_{50}$ value of $3.01{\mu}M$. Therefore, this compound might provide a basis for novel anti-inflammatory drugs.

  • This study was carried out to explore a non-chemical strategy for enhancing productivity by employing some antagonistic rhizobacteria. One hundred eighteen bacterial isolates were obtained from the rhizospheric zone of various crop fields of Gangwon-do, Korea, and screened for antifungal activity against Fusarium wilt (Fusarium oxysporum f. sp. lactucae) in lettuce crop under in vitro and in vivo conditions. In broth-based dual culture assay, fourteen bacterial isolates showed significant inhibition of mycelial growth of F. oxysporium f. sp. lactucae. All of the antagonistic isolates were further characterized for the antagonistic traits under in vitro conditions. The isolates were identified on the basis of biochemical characteristics and confirmed at their species level by 16S rRNA gene sequencing analysis. Arthrobacter sulfonivorans, Bacillus siamensis, Bacillus amyloliquefaciens, Pseudomonas proteolytica, four Paenibacillus peoriae strains, and Bacillus subtilis were identified from the biochemical characterization and 16S rRNA gene sequencing analysis. The isolates EN21 and EN23 showed significant decrease in disease severity on lettuce compared to infected control and other bacterial treatments under greenhouse conditions. Two bacterial isolates, EN4 and EN21, were evaluated to assess their disease reduction and growth promotion in lettuce in field conditions. The consortium of EN4 and EN21 showed significant enhancement of growth on lettuce by suppressing disease caused by F. oxysporum f. sp. lactucae respectively. This study clearly indicates that the promising isolates, EN4 (P. proteolytica) and EN21 (Bacillus siamensis), can be commercialized and used as biofertilizer and/or biopesticide for sustainable crop production.

  • The thesis is to look for the method of applying process drama for bilingual education in multicultural society. This purpose can be resolved in three steps: first, to understand the purposes and functions of education changing to multicultural society; second, to survey the need of bilingual education conformed to its purposes and functions; last, to understand the theoretical background of process drama and seek the method of utilizing it to bilingual education. Recently, the Korean society is also changing to multicultural society with international marriages and immigrant workers. But they have difficulties in communicating in Korean, and their children have even the same. Under the basis of multiculturalism wanting peace and mutual respect between cultural groups, they have to be educated in equality. This is why the bilingual education is needed in our society. Process drama, a widely used term for educational drama in Britain, claims its effectiveness for L1, L2 and bilingual education, for the principal medium in drama is language and what drama delivers is related to meaningful human experiences. It is also supported on script theory of linguistic therapy. Kase-Polisini classifies the developmental process of education drama into 1) planning, 2) playing and 3) evaluation. This process can be applied to educational drama for language as well. Rather, educational drama applying to bilingual education has even more availability with the varieties of group organization and subject matter. Conclusively speaking, the group of dual language schools can be organized into 1) mother-tongued group, 2) mother-tongued and L2 group, 3) multilingual group, or 4) L3 group in educational drama activity, as the class generally consist of the mixed multilingual children. And the subject matter can deal with 1) the Korean society and culture, 2) the society and culture of the purposed language country, or 3) the society and culture of the third nations.

  • Objectives: It is a statistical study to examine the data of CaPSPI (Diagnostic System for Climacteric and Postmenopausal Syndrome Pattern Identification), developed for diagnosis of menopause disorders and to record the status of treatment of it. Methods: From November 1, 2020 to June 19, 2021, 36 cases of data of 33 respondents of the CaPSPI were analyzed. For the use of the basic data of the clinical menopausal disorder, we investigated frequency of menopausal symptoms and the difference between them depending on the period of menopause, and the presentation of usage prescriptions. And the diagnostic results for three kinds' diagnosis [for examination (D1), for treatment (D2), by doctors (D3)] were compared. The diagnostic consistency of D1 and D3 and the statistical significance between DT and disease elements (證素) was investigated. Results: 1. Hot flush was the highest in the symptom survey of the menopause that the subjects complained of, followed by insomnia. There was no significant difference in symptom expression according to menopausal period. 2. The diagnostic consistency of D1 and D2 showed significant diagnostic consistency only in liver depression, and the diagnostic consistency of D1 and D3 showed significant consistency in liver depression and Dual Deficiency of Heart and Spleen. 3. D3' diagnosis and disease elements had statistical significance for cases of P<0.1 was found to be related to the theory of oriental medicine. Conclusions: It is needed to continue to accumulate diagnosis and treatment results through CaPSPI in the future to strengthen the basis for patten identification and treatment of menopause disorders.
