Background: The author analyse the impact of extracapsular lymph node spread and bone engagement in the ipsilateral neck of patients suffering squamous cell carcinoma (SCC) of the lower lip. Methods: The data of 56 neck dissections performed in patients suffering SCC of the lower lip between January 2000 and December 2008 were retrospectively analysed. Statistical analysis was performed with the Kaplan-Meier life table method, and the survival rate was investigated with the log rank statistic and significance test. The values were considered statistically significant at p<0.05. Results: Nine patients took advantage from simultaneous treatment of tumor and prophylactic neck dissection (level I-III), reaching 100% survival rate. Patients suffering metastasized disease, who received radical neck dissection at the time of tumor treatment, presented 83.3% survival rate. Patients who underwent previous surgery and radiotherapy presented worse prognosis although radical neck dissection in case of extra-capsular spread only (24.7%) and osseous engagement (22.2%). Conclusion: Prophylactic neck dissection (level I-III) is recommended in T3-T4 N0 SCC. Simultaneous treatment of tumor and cervical lymph nodes provides a better prognosis as respect to delayed nodal management. Extra-capsular spread with or without bone engagement represents independent risk factor responsible for high mortality rate of SCC of the lower lip.

The purpose of this study is to conceptualize PUST (Public understanding or science and technology) with a new theoretical perspective and to measure the Korean PUST through a national survey. Then, it suggests policy implications of improving the Korean public understanding of science and technology. Our new theoretical perspective is focused on an information receiver's one rather than an information provider's one. Thus, we concepualized PUST as a process of engagement: how a citizen becomes to be engaged to science or technology. It does not stress how hard s/he is pushed to learn science or technology. A national survey was done by a face-to-face interview method. About 1,200 adults were sampled from 18 or more years old population by a stratified area sampling method which had been used as a common and reliable one in South Korea. Each half of the total sample were for science or technology. The survey was conducted in September, 2001. We found that many Korean adults had positive but disproportionate impressions of science or technology that were related mostly to utilities for life such as computer, internet, car, refrigerator, television, etc. Most of them failed to continue to be engaged to sciences and technologies after first exposure to them through compulsory education. They were not able to relate sciences or technologies to solving individual or social salient problems. This study shows that PUST would be improved by our engagement to sciences or technologies through their relationship with social problems or issues.

The purpose of this study was to examine the effects of the job characteristics of the PR practitioner on flourishing and to identify the mediating effect of the meaning of work and job engagement. This study used a survey of 353 PR practitioners from PR firms and the hypothesis was verified by gathering the data of the job characteristics, the meaning of work, the job engagement and the flourishing by conducting hierarchical regression analysis and SPSS Process Macro bootstrapping analysis. The results showed that the job characteristics of the PR practitioner were found to influence the flourishing with the double-mediation effect, the meaning of the work and job engagement. The more PR practitioners regard their work affects their surroundings, the higher the degree of autonomy is, and the more they get feedbacks they engaged more, as they valued their job more thereby experience flourish more. Moreover, when PR practitioners valued their job more, they more engaged in their work and experience flourish. The meaning of work revealed to be the important factor to affect flourish regardless of the job characteristics and the job engagement so that gained the results that PR firms' effort to elevate the meaning of work of PR practitioners has is important. The study findings suggest that PR practitioners' flourishing is manageable in the organization by paying attention to oneself in the aspect of the organization, not leaving in individual areas. Limitaions and implications for future studies were discussed.

As a medium for communication on science and technology, science museum could be important to adults who finished formal school education. By analysing all the exhibits at the National Science Museum and conducting a face-to-face interview survey toward 100 adult visitors, based on the PEP / IS model's perspective(Kim, 2007), this study aimed to find a way to induce many adults to visit science museum from the information consumer's viewpoint, not the information provider's one. The result was that most of the exhibits were not related to problems which people focused attention on. About half of visitors, therefore, did not relate their problems with exhibits and responded that there was no relationship between exhibits and their everyday life. However, they had an idea that science and technology could contribute to solving their problems. These findings could suggest that first, science exhibits in relation to people's focused problems or issues are to be developed, second, programs for parents who are accompanied by their children are to be developed, and last, adults' engagement in planning the science museum exhibits is to be considered.

The history of the Bakken Museum, the Museum of Electricity in Life, is useful to understand the universality and particularity of a local science museum. Beginning with the small collections at the medical device company, the Bakken Museum has expanded its scope and facilities by reidentifying its mission from research institute to educational center. The educational turn of the Bakken Museum has been completed with two remarkable events: the launch of the Summer Institute in 1984 and the construction of the new education facility, New Wing, in 1999. During this change, the museum staff developed unique strategies for public engagement, using the history of science and technology as an educational tool. The shift of the Bakken Museum's mission provides an excellent example of how a local museum could meet the social needs for museums to be educational centers by utilizing its history and collections.

Logistics industry is being an important industry in Vietnam with the contribution from 8-10% of GDP recently. This industry employs about 15 millions people. Increasing the employees' job satisfaction is become one of the most concerns of managers in logistics companies to strengthen the employee engagement and improve their business performance. The aim of this study is to investigate how employees' perceptions of job satisfaction are influenced by factors such as job stress, leadership capability, work-life balance, and demographics. 426 workers in the logistics sector in Vietnam were surveyed online. The acquired data was analyzed using a structural equation model. In total 16 hypotheses were established, 13 of which were deemed to be significant. The results demonstrate how the literature-informed second-order constructs can potentially explain the overall job stress, leadership capability, and work-life balance of employees in the Vietnamese logistics industry. These variables account for 54.8% of job satisfaction. This study makes a theoretical contribution to the extant literature by showing how researching second-order constructs can improve the theory's capacity to predict employees' job satisfaction. The paper concludes with a set of recommendations for the management of logistics firms in Vietnam.

The purpose of this study was to describe the family life and relationships of national family center users in 2023. A sample of 1,086 adults was recruited from 48 family centers across South Korea. Participants, both online and offline, reported on various aspects of family life, including satisfaction, gender equality, work-home-life balance, family leisure, and internet usage for family and household purposes. Additionally, family relationships were explored in terms of dynamics with a spouse, children, and adult children. Data were analyzed using descriptive statistics and t-tests. In the family life domain, center users reported a high level of satisfaction, with women exhibiting greater awareness of gender equality and higher engagement in household chores than men. Furthermore, although a moderate balance among work, home, and life was reported, time emerged as a significant challenge for family leisure. Regarding technology, center users frequently utilized the internet for family communication, leisure, shopping, and household management. In the family relationships domain, men were more satisfied with spousal relationships than women. Center users reported high satisfaction with parent-child relationships. Parents of school-aged children perceived economic burdens, while those with adult children frequently provided psychological and instrumental support. These findings suggest the need for program modification and the development of new initiatives within national family centers to better support the diverse needs of families in terms of life satisfaction and relationship dynamics.
