  • What are the identification criteria elementary school teachers prefer? What are the characteristics of students that teachers consider when nominating them to gifted programs? Will those criteria of identification/nomination differ as to teacher experiences related to gifted education or teacher involvement in the professional development? This study aims to find the answer to these questions. For this purpose, a total of 511 elementary school teachers with a varying degree of experiences with gifted education were recruited from 23 schools in 11 school districts in Seoul. The results show that teachers generally preferred task commitment, creativity, curiosity, and domain specific talents as criteria for identifying gifted students, while perceiving achievement records, total grades, leadership, and general intelligence as less important. Teachers experienced in gifted education or having been involved in professional development perceived curiosity, task commitment, and creativity as more important than teachers without such experiences. The importance-performance analysis of identification criteria indicates that teachers reported high importance on task commitment, curiosity, and creativity, but those factors were less considered in actual nomination. On the contrary, teachers reported low importance on quick learning and achievement(total grades, subject grades), but those were highly considered in nomination. A similar pattern was found in both experienced and nonexperienced teachers although the importance-performance gap was higher for the latter. Implications for teacher nominations and professional development were discussed.

  • Background: Tobacco consumption has become pandemic, and is estimated to have killed 100 million people in the 20th century worldwide. Some 700,000 out of 5.4 million deaths due to tobacco use were from India. The era of global modernization has led to an increase in the involvement of women in tobacco consumption in the low income and middle-income countries. Tobacco consumption by females is known to have grave consequences. Objectives: To assess: (1) the tobacco use among urban and rural women; (2) the discrepancy in the knowledge, belief and behavior towards tobacco consumption among urban and rural women in Durg-Bhilai Metropolitan, Chhattisgarh, Central India. Materials and Methods: The study population consisted of 2,000 18-25 year old young women from Durg-Bhilai Metropolitan, Chhattisgarh, Central India, from both urban and rural areas. Data were collected using a pretested, anonymous, extensive face to face interview by a female investigator to assess the tobacco use among women and the discrepancy in the knowledge, belief and behavior towards tobacco consumption among urban and rural individuals. Results: The prevalence of tobacco use was found to be 47.2%. Tobacco consumption among rural women was 54.4% and in urban women was 40%. The majority of the women from urban areas (62.8%) were smokers whilst rural women (77.4%) showed preponderance toward smokeless tobacco use. Urban women had a better knowledge and attitude towards harms from tobacco and its use than the rural women. Women in rural areas had higher odds (1.335) of developing tobacco habit than the urban women. Conclusions: Increased tobacco use by women poses very severe hazards to their health, maternal and child health, and their family health and economic well-being. Due to the remarkably complex Indian picture of female tobacco use, an immediate and compulsory implementation of tobacco control policies laid down by t he WHO FCTC is the need of the hour.

  • The present study was made of the effects of abscisic acid(ABA) and calcium ions on dark respiration in protoplasts isolated from the basal intercalary meristematic tissues of oat (Avena sativa L.) seedlings. The influences of calcium channel blockers diitiazem(DTZ), verapamil(VPM), and $LaCl_2$ and the calmodulin antagonist trifluoperazine(TFP) on protoplast respiration activities were also investigated in order to evaluate the possible involvement of calcium channels and calmodulin during the dark respiration. The ABA only caused an 21% inhibition of protoplast respiration at $10^{-6}\;M$, but the extent of inhibition was very low by calcium treatments in the absence of ABA. In the presence of $10^{-6}\;M$ ABA, however, this inhibition of respiration increased by the increment of calcium ions concentrations. Treatments of DTZ and VPM were all found to restore the calcium-dependent inhibition of protoplast respiration by ABA and it was the same in thc $LaCl_2$ treatment except at $10^{-4}\;M$. At concentration from $10^{-6}\;M\;to\;10^{-4}\;M$, TFP also restored an inhibition of respiration. These results support the possibility that ABA increases plasmalemma permeability to calcium ions which might then bind to calmodulin to regulate oat protoplast dark respiration.ration.

  • This study was carried out to find out the effect of conflict between profession groups within medical institution. For the purpose, the questionnaire-based research was done with 605 persons consisting of specialists, residents, nurses, radiologic technicians, clinicopatholigic technicians, health record administrator, administrative employees who are working in a university hospital located in Taegu City from February 15, 1997 to March 2, 1997. The results of the study were summarized as follows. The subject profession group against which each profession group feels the most conflict in interprofession mutual recognition relation was found out as follows; Specialists(34%) against colleague specialists, residents(54.0%) against nurses, nurses(54.8%) against residents, radiologic technicians(44.0%) against residents, and clinicopathologic technicians(34.5%) against nurses, while it was shown that health record administrator felt even conflict against residents, nurses and administrative employees and administrative employees(48.1) did against nurses. Most employee group answered that medical specialists have a one-sided and individual attitude toward all affairs, while both medical specialists and administrative employees of hospital answered that nurses are one-sided. It was shown among such groups that radiologic technicians' conflict results from their thinking which mutual dependence and cooperation are lowest while individual difference is highest, clinicopatholigic technicians' conflict from the problem in mutual communication, medical specialists' conflict from difference in goals greater than other group, respectively lower than other group. The rate of vertical conflict between groups was highest for the health record administrators and then for the radiological technicians, while it was lowest for the medical specialists and then for the nurses. In addition, the rate of horizontal conflict was high for both medical specialists and nurses, but it was low for the health record administrations and clinicopathological technicians. The group with the highest job satisfaction was the medical specialists and nurses, and the group with the highest involvement in organization was the medical specialists and administrative employees. Also it was shown that both medical specialists and clinicopathological technicians show a favorable attitude toward patients. Factors having an effect on the vertical conflict included difference in goals, cooperation within group and leadership. It was shown among those factors, however, that only the leadership has an effect on all the groups evenly. The horizontal conflict was influenced by such factors as educational level, mutual dependence, difference in goals, cooperation within group, and individual difference, when an important factor was the difference in goals for all the groups. Their attitude toward patients was influenced by the vertical conflict and age, but the vertical conflict was the most significant factor for the medical specialists. In conclusion, it is required to control properly the conflict between employees as well as between profession group and to execute good leadership, so as to improve patients' satisfaction which is the key goal of hospital.

  • This paper is the first to present the incidence and overall survival of patients with squamous cell carcinoma of the head and neck (SCCHN) from the extreme northern part of the Philippines. We retrospectively retrieved the records of patients with histologically-confirmed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx and larynx at the Mariano Marcos Memorial Hospital and Medical Center, Ilocos Norte, Philippines, from 2003 to 2012 and analysed prognostic factors associated with survival. Of the 150 cases, only 80 (53.3%) were still living when the study was terminated. Median age at initial diagnosis was 61.5 years and the male to female ratio was 7:3. The majority of the cases had tumours in the oral cavity (50.7%), followed by the larynx (36.7%). Sex (log rank=1.94, p value/${\alpha}$=0.16), tumor site (log rank=0.02, p value/${\alpha}$=0.90), tumor grade (log rank=1.74, p value/${\alpha}$=0.42), and node stage (log rank=0.07, p value/${\alpha}$=0.80) were not shown to be associated with the survival of our cases. Only 45 (30.0%) had no regional lymph node involvement (N0) at presentation and 12 (8.0%) had already developed distant metastases. Among the 150 patients, 71 (47.3%) were not able to receive treatment of any kind. Oddly, treatment (log rank=1.65, p value/${\alpha}$=0.20) was also shown to be not associated with survival. The survival rate of those who underwent surgery, radiotherapy, or both was not statistically different from those who did not receive any treatment. Only the tumor stage (log rank=4.51, p value/${\alpha}$=0.03) was associated with patient survival. The overall mean survival was 49.3 months, with survival rate diminishing from 88.3% during the 1st year to 1.80% by end of the study. This relatively low survival rate of our cases only reflects their poor access to quality diagnostic and treatment facilities.

  • This experiment was performed to understand the changes in plasma leptin in association with plasma IGF-1, body weight and ADG from early growing to late finishing stages of Holstein steers. Blood collection was performed by arterial vein puncture at selected monthly ages of 1 (54 kg), 2.6 (103 kg), 7.2 (205 kg), 13.5 (314 kg), 16.9 (414 kg), 22.2 (550 kg), 24.9 (626 kg) and 27.4 months (695 kg). The blood was analyzed for leptin using the multi-species leptin RIA with recombinant bovine leptin (rbleptin) as standard, plasma IGF-1 was also measured using RIA. Against the standard rbleptin, the multi-species Leptin RIA system's sensitivity, cross reactivity, slope and recovery of 41.0 ng/ml rbleptin in plasma were 4.9 ng/ml, 11.22%, -1.396 and 97.8%, respectively. Plasma leptin measured were more than 5.0 ng/ml, which enable multi-species RIA system to investigate plasma leptin in normal growing steers. Body weight resulted to a highly significant second-degree polynomial relationship with plasma leptin (q=0.54, p<0.0001) and plasma IGF-1 (q=0.44, p<0.0001) from 1 to 27.4 monthly ages. However, the second-degree polynomial curve of plasma leptin and IGF-1 differs showing a concave and convex curvilinear relationship, respectively. ADG was not significantly associated to plasma leptin (r=0.06, p>0.05) and plasma IGF=1 (r=0.06, p>0.05) from 1 to 27.4 monthly ages. Low coefficient, but significant associated increase of plasma leptin and IGF-1 (r=0.12, p<0.008) from 1 to 27.4 months was observed. The uncoordinated increases of plasma IGF-1 at growing and plasma leptin at fattening period, may indicate (1) indirect involvement of endogenous IGF-1 on leptin secretion, and (2) IGF-1 level may signify lean and bone accretion while plasma leptin may mirror body fatness across the monthly ages of Holstein steers.

  • Purpose - This study examines the positive impact of the social distance between producers and users of online content, investigating and analyzing the most popular Web content. In addition, it tries to elicit the matching effect that appears when the individuals'cultural background is consistent with social distance. Research design, data, and methodology - We collected and analyzed actual data about 4,981 videos clips on YouTube, looking at six countries in order to verify the content of this study. Based on the results of the data analysis, the study conducted behavioral measurements on popularity, social distance, culture, and user engagement. The unit of analysis was the content and we collected information about the content producers and the content records. We controlled the views, comments, likes, calendar dates, and ages in the empirical models. The data was collected in 2011, with the records coming from South Korea, Japan, China, U.S., German, and France. A total of 4,980 elements were analyzed in the model. The empirical model estimated is the bivariate negative binomial distribution (NBD) model. Results - It turns out that there is a possibility that the matching effect can be diminished by variables that reflect the psychological involvement of user engagement. This study proposes academic and practical implications based on these research results. This research shows the positive effect of social distance between users and producers on the increased performance of the online content. We find the effect of social distance to be a stronger tendency in collectivism. The collectivists follow their sense of friendship and intimacy in their culture and, the social congruence effect can be found there as well. The effect, however, could erode in a social case where users are motivated by strong intrinsic and psychological factors. In addition, user engagement complicates the process of user decision making regarding the information. Conclusions - This study examines how the differential effects of social distance caused by culture could disappear through user commitment as a complicated user motivation. Some potential implications are as follows. First, a firm in the collectivism culture has to communicate based on the social distance. In fact, most online channels do not have a function that indicates the social distance as measured by favorites or subscribers. This function could help increase the performance of the content in online channels, but this increasing effect can only be found in a collectivist culture. Based on this, the firms have to communicate and announce to users the actual social distance between users and producers. Second, firms should develop a system that discovers the social distance and culture and shows these measures to users and producers, since the congruence effect between social distance and culture is found only for low user engagement. The firms can take the advantage of the congruence effect only for the development of the social distance and culture visualized system.

  • Purpose : We experienced 7 patients with Kikuchi-Fujimoto disease(KFD) who had presented a prolonged fever and lymphadenopathy. The clinical and the laboratory aspects of the patients were analyzed. Methods : The medical records of the 7 KFD patients, who were confirmed by excisional lymph node biopsy from January 1996 through December 2003, were retrospectively analyzed. Results : The mean age of the children was $11.4{\pm}2.8$ years(ranging from 8 to 15 years). The male to female ratio was 1.3 : 1. The median duration of the fever prior to admission and the total duration of the fever were 12 days(ranging from 5 to 65 days) and 27 days(ranging 9 to 75 days), respectively. One patient had supraclavicular lymphadenopathy, 5 had cercical involvement, and 1 had axillary lymphadenopathy. All the histologic findings of the lymph nodes biopsies showed the characteristic findings consistent with KFD such as paracortical necrosis with karyorrhexis and an increase in the number of phagocytic histiocytes and atypical lymphocytes. As for the laboratory findings, leukopenia($3,800{\pm}700/mm^3$), anemia(hemoglobin, $11.0{\pm}1.2g/dL$), an elevated erythrocyte sedimentation rate($42{\pm}17mm/hr$), and a relatively low C-reactive protein level($1.3{\pm}0.9mg/dL$) were noted. Four patients received conservative therapy with antipyretics, and 3 patients were treated with prednisolone. Conclusion : KFD is a rare disease, yet should be considered in the differential diagnosis for older children with prolonged fever and lymphadenopathy.

  • Sperm capacitation and acrosome reaction (AR) have been known to be Ca$^{2+}$-dependent events. Sperm capacitation accompanies with cholesterol efflux fiom plasma membrane, that eventually stimulates AR. However, whether the AR mediated by cholesterol efflux is Ca$^{2+}$ dependent has not been verified yet. Recently, methyl beta cyclodextrin (MBCD) was found to evoke AR by stimulating the cholesterol efflux fiom sperm membrane. In the present study, we examined the requirement of Ca$^{2+}$ in the MBCD-induced AR. During incubation of sperm in the bicarbonate buffered media MBCD increased AR in a dose-dependent manner regardless of the Ca$^{2+}$ presence. In the presence of low molar concentration of Ca$^{2+}$ (100 ${\mu}$M), MBCD-induced AR was slightly increased compared to Ca$^{2+}$-free condition. In the absence of Ca$^{2+}$ supplement, spontaneous AR was slightly increased during the incubation but inhibited by 100 ${\mu}$M EGTA. MBCD potentiated AR even the presence of EGTA. However, EGTA attenuated MBCD-induced AR, suagesting the functional involvement of intracellular Ca$^{2+}$ in the MBCD-induced AR. Taken together, it was suggested that cholesterol efflux from the sperm plasma membrane was sufficient for induction of AR even in the absence of extracellular Ca$^{2+}$and that a condition permissive for mobilization of intracellular Ca$^{2+}$ is important for MBCD-induced AR.

  • The domestic CM business market has continued to grow, but its size is relatively small yet in comparison with the total size of the domestic construction industry. Evaluation of CM projects was conducted through questionnaire surveys. Both clients and CM firms showed positive satisfaction levels. Nevertheless, the clients' satisfaction levels were relatively low in safety management, cost management, and document and information management. Superior areas of CM tasks were time management and recovery scheduling, quality control and technical instruction, and design value engineering. On the other hand, inferior areas of CM tasks were claim analysis and dispute resolution, cost estimation, and life cycle costing. Both entities have agreed with the positive effects of CM involvement in terms of cost saving, time reduction, quality improvement, and safety incidents prevention to at least 0~5% extent.
