In recent years, the labor consciousness is gradually valued. During the process of pursuing sustainable operation, the enterprises treat occupational hazard risk as the waste of cost. The purpose of OHSAS 18000 occupational security and health management system is to systematically establish the business managerial measures in terms of occupational security and calamity prevention. This research proceeded with questionnaire analysis with respect to the relationship between the OHSAS 18000 system implementation and competitiveness in Taiwan's industries. The research result revealed that there was significant relationship between Taiwan firms' execution of OHSAS 18000 system and industry competitiveness. Thus, the enterprises can decide the proper managerial plans according to the result of their own risk evaluation to prevent the happening of accidents and reduce the operational cost. They can thus completely control business occupational hazard risk through "systematic" management.

The pyridinolysis of methyl phenyl phosphinic chloride is investigated kinetically in acetonitrile at -20.0 $^{\circ}C$. The Hammett and Br${\o}$nsted plots for substituent X variations in the nucleophiles are biphasic concave downwards with a break point at X = H, and unusual positive ${\rho}_X$ (= 2.94) and negative ${\beta}_X$ (= -0.48) values are obtained for the strongly basic nucleophiles. A stepwise mechanism with a rate-limiting step change from bond breaking for the weakly basic pyridines to bond formation for the strongly basic pyridines is proposed on the basis of biphasic concave downward Hammett and Br${\o}$nsted plots. Unusual positive ${\rho}_X$ and negative ${\beta}_X$ values are rationalized by the isokinetic relationship. The pyridinolyses and anilinolyses of four $R_1R_2$P(=O)Cl-type substrates, dimethyl, diethyl, methyl phenyl, and diphenyl phosphinic chlorides in acetonitrile are compared to obtain systematic information on phosphoryl transfer reaction mechanism. The combination of the two ligands, Me and Ph, shows unexpected kinetic results for both the anilinolysis and pyridinolysis: greatest magnitude of $k_H/k_D$ (= 2.10) involving deuterated anilines $[XC_6H_4NH_2(D_2)]$ for the anilinolysis, and exceptionally fast rate and biphasic concave downward free energy correlation for the pyridinolysis.

Objectives: The purpose of the study was to investigate the relationship between oral health perception and oral health-related quality of life-14(OHIP-14) in a geriatric hospital. Methods: A self-reported questionnaire was completed by 230 elderly people in a long-term care institution. The questionnaire was consisted of items on general characteristics, oral health perception and OHIP-14. Except incomplete answers, 226 data were analyzed statistically with one-way ANOVA, t-test, Pearson's correlation coefficient and post hoc Tukey test and ANOVA when significance was set at 0.05. Results: The OHIP-14 showed a negative linear relationship(p<0.01) of r=-0.272 with the oral health perception. Among the subgroups of the OHIP-14, quantitative linear relationship(p<0.01) was shown in functional limitation(r=0.822), physical pain(r=0.825), psychological discomfort(r=0.568), physical disability(r=0.895), psychological disability(r=0.652), social disability(r=0.804) and handicap(r=0.818). Conclusions: In order to improve the oral health perception and OHIP-14 in a geriatric hospital, it is necessary to develop continuously a variety of oral health education and systematic oral health promotion program.

As the volatility increasement of the number of tourist, there was been controversy over supply-demand imbalance in hotel market. The purpose of this study is to analysis on determinants of hotel occupancy rate in Jeju Island. The quantitative method is based on cointegrating regression, using an empirical dataset with hotel from 2000 to 2017. The primary results of research is briefly summarized as follows; First, there are high relationship between total hotel occupancy rate and hotel occupancy of foreign tourist. The volatility of hotel occupancy is caused by foreigner user than local tourists though local tourist high propotion of hotel occupancy in Jeju Island. Second, hotel occupancy of local tourist has not relationship with demand and supply variables. Because some hotel users are not local tourists but local resident, and effects to other variables of hotel consumer trend, accommodation such as Guest house, Airbnb. Third, there are high relationship between foreign hotel occupancy rate and demand-supply variables. These research imply that total management of supply-demand is very important to seek stability of hotel occupancy rate in Jeju Island. Also it can provide a useful solution regarding mismatch problem between supply-demand as well as development the systematic forecasting model for hotel market participants.

Most of enterprises depend on a data modeler during developing their management information systems. In formulating business requirements for information systems, they widely and naturally use the interview method between a data modeler and a field worker. But, the discrepancy between both parties would certainly cause information loss and distortion that lead to let the systems not faithful to real business works. To improve or avoid modeler-dependant data modeling process, many automated data design CASE tools have been introduced. However, since most of traditional CASE tools just support drawing works for conceptual data design, a data modeler could not generate an ERD faithful to real business works and a user could not use them without any knowledge on database. Although some CASE tools supported conceptual data design, they still required too much preliminary database knowledge for a user. Against these traditional CASE tools, we proposed a Requirement-Oriented Entity Relationship Model for automated data design tool, called ROERM. Based on Non-Stop Methodology, ROERM adopts inner systematic modules for complete and sound ERD that is faithful to real field works, where modules are composed of interaction modules with a user, rules of schema operations and sentence translations. In addition to structure design of ROERM, we also devise detailed algorithms and perform an experiment for a case study.

The general morphological characters of Lysimchia sect. Spicatae were reviewed. From the results, numerical analyses were conducted based on 34 morphological characters from 14 populations of three species in Korea in order to investigate the key characters among the treated taxa and taxonomic delimitation and to discuss the systematic relationship. Habitat, leaf apices, presence or absent of hair on leaves, stipules, stems and bracts, branch of stems, kind of hair on floral axis and pedicels, shape of florescens were important diagnostic characters to identify the species. The relationship between Lysimachia clethoides and L. barystachys was more close than that of L. fortunei based on the quantitative characters. Also, a new key was made up from the result.

As ICT technology develops rapidly and social and consumer interactions require more knowledge of the technology, the interest for baby boomers' ICT technology acceptance is increasing as they age. However, previous studies have limitations as they lack a systematic and in-depth understanding of this phenomenon in which the emerging elderly population embraces emerging technology. To overcome this limitation, this study carried out a phenomenological study on baby boomers' ICT technology acceptance. In addition, since existing studies have just simply listed variables or proved the relationship between a few variables, this study aimed to find the relationship between variables by analyzing the data obtained through semi-structured interviews. Through this procedure, it was aimed to construct conceptual model which illustrates the relationships between variables so that understanding the phenomenon of baby boomers' acceptance of ICT technology with a holistic view could be possible. The ten variables suggested by Lee & Coughlin (2015) that cover multiple sides of baby boomers' technology acceptance were used. As a result, we found that there is a sequential relationship between these variables and different agents can be related to each variable in sequence. Also, from an ecological perspective, we analyzed baby boomers and their surroundings to find agents involved in this phenomenon.

Many species of Lymantria are important forestry pests, including L. dispar which is well known distributed from Asia to North America as an invasive species. Like of most other genera of moths, the systematic of this genus is still in dispute, especially on the monophyly and the relationship within this genus due to the fact that genus is very large and varied. This genus was morphologically defined only by a single aphomorphy. To clarify the monophyly of the genus Lymantria, to reveal the phylogenetic relationship among the Indonesian species, and to establish the genetic characters of Indonesian Lymantria, we analyzed 9 species of Indonesian Lymantria involving 33 other species distributed around the world based on nucleotide sequence variation across a 516-bp region in the CO I gene. The results showed that the base composition of this region was a high A+T biased (C: 0.3333). The results also showed that the monophyly of Lymantria was not supported by bootstrap tests at any tree building methods. Indonesian species was distributed into four different groups but the relationship among them was still in dispute. It indicates that relationships among the basal nodes (groups) proposed here were least valid due to the fact that the number of species may not be enough to represent the real number of species in the nature. Moreover CO I gene sequences alone were not able to resolve their relationships at the basal nodes. More investigations were needed by including more species and other genes that the more conserved.

The purpose of this study is to investigate the relationship between organizational culture (innovation culture, relationship culture, hierarchy culture, task culture) as perceived by organizational members and its impact on organizational justice and job performance. This contributes to providing additional data for the revitalization and development of the organizational system for efficient management and operation measures included in the organization's sustainable management. To this end, the hypothesis established through the traditional process of quantitative research was tested as follows. First, organizational culture showed a positive effect on organizational justice. Second, organizational culture had a positive (+) effect on job performance. Third, organizational justice was significantly analyzed in terms of job performance. In other words, the importance of systematic re-establishment and continuous implementation of organizational culture (innovation culture, relationship culture, hierarchy culture, task culture) and organizational justice consistent with organizational characteristics was emphasized in order to improve job performance, which is the result of organizational competitiveness. In addition, it is the aspect of drawing practical implications for strategic human resource management and human resource development to systematically improve it.
