Cervical cancer is the fourth most common cancer in women, with approximately 528,000 new cases and 266,000 women dying of it per year in the world. MicroRNAs have recently been in the spotlight as potential biomarkers that regulate gene expression and are involved in tumorigenesis. In the present study, we evaluated miR-1260b as a potential biomarker for screening of cervical cancer by quantitative reverse transcription PCR. We profiled the TCGA data of miR-1260b in 307 cervical cancer tissues. Then, miR-1260b expression levels in 10 cervical cancer tissues and 10 noncancerous tissues were investigated in a pilot study. miR-1260b was found to be significantly up-regulated in cervical cancer FFPE tissues as compared to those in cervical normal FFPE tissues (P = 0.006). The mean expression level of miR-1260b in late-stage (IIB-IVB) was higher than in those with early-stage (IA-IIA). Furthermore, high miR-1260b was found to be associated with high hTERT and Ki-67 mRNA expression, which are representative of tumor prognosis. The results of the pilot study suggest that miR-1260b may be used as a novel biomarker for improving the diagnosis of cervical cancer.

The port, differently from general working place, is a closed area to execute security, customs, and quarantine procedures. The loading and unloading is being done differently by cargoes, ships, berths, and equipments. To load and unload a lot of equipments and different types of labor are required, in which work flow is very complicated. As above mentioned the port is very unique and deteriorated working place including danger. The purpose of this thesis is to propose ways to analyze and establish the preventive measure for cargo handling accidents in port. We have collected 923 accidents happened at Incheon Port during the period from 1994 to 2003. And to analyze and establish the preventive measure we have employed an advanced 6sigma DMAIC technology presently in spotlight as the best tool for management innovation. For the purpose of effective safety management of cargo handling in port, this thesis will help to revise and establish the law, system, standard, and standard working manual with respect to the port loading and unloading system. Now frequency of cargo handling accidents in port is highest for the second time among all industries, so we proposed the new safety management system to substitute port safety committee and to take full charge of safety in Ministry of Maritime Affairs and Fisheries.

Among many types of flame retardants, the most available halogen-containing flame retardants were put under environmental restrictions in their use, so non-halogen type phosphorus-based flame retardants have come into the spotlight. When added to resins, flame retardants commonly bring about thermal degradation and decrease in mechanical properties of resins. Studies of new flame retardants were carried out in an attempt to minimize degradation of physical properties and require enough flame retardancy. In this study, three types of non-halogen phosphorus-based flame retardants were synthesized with diaryl alkyl phosphate esters, aromatic phosphate esters and phosphonium nitron flame retardants, which were then identified for the synthesis and thermal properties by gas chromatography (GC), IR and thermal gravimetric analysis (TGA).

Nowadays a sense of community based on our community further weakens due to globalization, industrialization, the development of transportation and communication, etc and the community as cultural and psychological units is focused on. In other words, the concept that emphasizes the aspect of 'we' sharing the unique value and goal of community is used. In this current situation, school as an important community organization has been in the spotlight. In particular, college compared with other communities has a special influence on the community. Therefore it is regarded as an important community organization and its importance as part of our efforts to decrease the college students wastage rates continues to grow. The study about school as an important community organization has been conducted actively. However the people in most studies are elementary, middle, and high school students, so there are limitations to what these study findings apply to college. Therefore, this study conducted factor analysis of college sense of community for local college students, categorized it, analyzed the factors having influence on each factor and then looked for suggestions of ways to strengthen college sense of community. According to study, sense of community is categorized into three factors such as 'sense of belonging', 'sense of solidarity', and 'sense of emotional closeness'. After analyzing the factors influencing types of sense of community, factors relevant to them are grades, intimate friends, subjective well-being, community volunteer work, college service satisfaction, and so on.
