Purpose - Corporate patent management refers to an organization belonging to the government or an intergovernmental organization that plays a bigger role in controlling patents. The purpose of the present study is to investigate and suggest brief solutions regarding how companies should manage their patents, maximizing their commercial values. Research design, Data, and methodology - Since the current researcher needed to optimize authenticity, the datasets were used primarily for collecting data from various sources examined by peers. This research used a claim from PRISMA (preferred reporting items for systematic reviews and meta-analysis) to identify prior studies within the limits of the sample. Result - The results revealed that corporate patent management is faced with different problems in the course of its operations. It faces many different critics from the outside world; therefore, a need to solve those problems. This study strongly suggests there are seven solutions to manage companies' patents. Conclusion - The conclusion of this study points out that The prolonged period has given some business organizations a competitive advantage over others especially that belong to industries that have a lower propensity to adopt patent rights. As a result, some business organizations have grown relatively faster than others within the long period they remain as patent rights members.

In recent decades, the socio-hydrology community has developed several socio-hydrological frameworks to understand the complexity of the coupled human-water system. Although there have been efforts to relate sociology and hydrology, there still have been some insights that remain debatable. As for this study, the Value-belief-norm theory was used to represent the human behavior in order to connect the human-water system. The theoretical framework of values, beliefs and norms was developed to understand the human culture towards the environment. In addition to the theory, norms are legislation of human behavior in the society while the values are the guiding principle to motivate beliefs and norms. The overview of this study implied on developing a socio-hydrological model consisting of the four systems defined as hydrology, socio-economy, technology and institutional. The interconnectors between the four systems are the key variables and parameters representing a module namely the causal loop diagram. Moreover, water quality, size of population, infrastructure capacity and norms are the key variables to connect the four systems. The developed model will be applied to Han River to represent the coevolutionary of the dynamics of human-water systems.

The purpose of this study is to measure the degree of discrepancies in the bilateral trade data between South Korea and its five major trade partners and to identify the key factors causing the discrepancies. By analyzing statistics based on the CIF/FOB ratio estimation and taking into consideration the trade flow via Hong Kong, the study finds that the discrepancies in South Korea's trade data with the US, Vietnam, and Japan are insignificant. In case of Hong Kong, however, the value of South Korea's import from Hong Kong is extensively inconsistent with Hong Kong's export to South Korea(i.e. the mirror data) while the value of South Korea's export to Hong Kong generally corresponds to its mirror data. Such discrepancies are caused by differences in recording re-exports, which are often found in the trade flow via entrepôt economics including Hong Kong. Meanwhile, discrepancies in reported bilateral trade flows between South Korea and People's Republic of China(PRC) remain relatively marginal. The discrepancy of statistics between South Korea as the exporter and PRC as the importer is mainly caused by the trade flow via Hong Kong. On the other hand, the discrepancy of statistics between South Korea as the importer and PRC as the exporter is assumably due to the differences in attribution of trade partners.

This study examines knowledge, attitudes and behaviors toward sexual activity among 412 college students in Seoul. An 127-item questionnaire is used in order to understand and consider alcircumstances involved in decisions about sexual activity, and to reflect to the course on healthy sexuality. The major findings are as follows: 1. ‘Books/media’ and ‘friends’ are the primary source of sexual knowledge. 2. Despite the increased number of sxeducation programs, peers apparently remain the major source of information and the counsellor of the sexual problems(71.6%). 3. About ninety percent of males and 14.2 percent of females masurbate. Although mastubation is anormal response to pleasurable bodily feelings, students feel ‘unnatural’, ‘bad’ or ‘guilty’. 4. For some students, sexual intercourse is perceived as the natural outgrowth of love. More than thirty oercent of males and 8. 1 percent of females are engaged in inter -course. 5. Asking parents or teachers to be specific in talking about sex makes it uncomfortable to discuss sex. 6. Sex education should begin in the family and in school in early childhood and continue throughout life. 7. Sexual feelings and emotions are stirred up differently between male and female by sexual sensations. 8. Half of the intimate relationship with opposite sex shows a love relationship with sexual closeness and pleasure. Unguided reading or peers remain the primary source of information about topics like masurbation and sexual technique. Thus, schools should be responsible for the more value-laden subjects (such as birth control, homosexuality, and sexual techniques). And inclusionof a peer education componebt that modified college students' perceived peer norms may be the intervention method of choice. The prevention of health problems is far more desirable than treatment. The earlier the knowledge and skill to make healthful decisions are instilled, the greater the chance a healthful lifestyle will be adopted. School is the logical place in our society to provide the college students learning opportunities essential to developing the knowledge and skills to choose a healthful life course.

In this study, 37 subjects with normal facial shape and normal occlusion are classified and reference value for such classification was investigated. Difference in position of maxillary incisor was studied according to the cl assification. Moreover, by investigating correlation between factors affecting forehead morphology and positio n of maxillary incisor, following results have been obtained. 1. Morphology of forehead can be classified as angular type, round type, straight type, and concave type. 2. There were no specific reference value for evaluation of forehead morphology but possibilities of evaluating forehead morphology using S value and forehead length (Tri-Gla) still remain. 3. There were no correlation between forehead morphology and position of maxillary incisor. 4. Forehead inclination and Andrew analysis show statistically significant negative correlation. That is, as forehead inclination increases, maxillary incisor is positioned posteriorly and this relationship can be shown as following equation, Andrew analysis = -0.39*Forehead inclination.

Recently the meaning of the road name address is expended as an information through the revision of the Road Name Address Act. As this revision, the address of things (AoT) become more important indicating the possibility for the expansion to the related business. However, recent study about AoT does not concern how the current priority system works from the first research. In this study, we analyze perception about addressable object between AoT experts and public using AHP analysis. We structured the importance of addressable objects as two categories; urgency and value creation. The necessity in emergency or daily, accessibility and welfare conform the urgency index. Meanwhile, public value creation in public domain or profitability in the business area and economics conform value creation index. We conducted survey for total of 89 of experts and public. The results of this study indicate the relative importance of AoT measured by experts and public. Generally, public tend to concern more about accessibility conforming the urgency index than experts. Moreover, the public WiFi and the sports complex scored the high priority among the remain addressable objects, in respect of the urgency and the value creation. This result could be implemented for the activation of the smart city industry base on the geospatial information including AoT.

Genetic instability contributes to the development and progression of gastric cancer, one of the leading causes of cancer death worldwide. Microsatellite instability (MSI) has been hypothesized to be involved in carcinogenesis, althgough its mechanisms and exact roles in gastric cancer remain largely unknown. Our aim was to identify associated clinicopathological characteristics and prognostic value of MSI in gastric cancer and precancerous lesions including gastritis, metaplasia, dysplasia, and adenoma. Because mitochondrial DNA has a different genetic system from nuclear DNA, the results of both nuclear MSI and mitochondrial MSI in gastric cancer were reviewed. This review provides evidence that genetic instability of nuclear and mitochondrial DNAs contributes to early stages of gastric carcinogenesis and suggests possible roles in predicting prognosis.

The advance of All-IP digital convergence is now triggering fundamental changes in the media industry. This article analyzes the evolution of the media industry based on a value chain model, with a special emphasis placed on the impact of digital technology on the structure of media production, distribution, and consumption. As the Internet has evolved into an access channel for all forms of media, the boundaries of the media industry remain unclear and open thus enabling anyone to become a creator of media. Furthermore, the scope of media continues to become more dynamic as competition grows between older and more innovative forms of media. In this light, adapting to innovative technologies and more effectively meeting the needs of customers represent key factors for the continued evolution of the media.

Simulation is performed to analyze the characteristics of turbulent spray combustion in a diesel engine condition. An extended Conditional Moment Closure (CMC) model is employed to resolve coupling between chemistry and turbulence. Relevant time and length scales and dimensionless numbers are estimated at the tip and the mid spray region during spray development and combustion. The liquid volume fractions are small enough to support validity of droplets assumed as point sources in two-phase flow. The mean scalar dissipation rates (SDR) are lower than the extinction limit to show flame stability throughout the combustion period. The Kolmogorov scales remain relatively constant, while the integral scales increase with decay of turbulence. The chemical time scale decreases abruptly to a small value as ignition occurs with subsequent heat release. The Da and Ka show opposite trends due to variation in the chemical time scale. More work is in progress to identify the spray combustion regimes.

In this paper, insulations characteristics by temperature changes(+30~-40[$^{\circ}C$]) of $SF_6$ gas in the experimental chamber were studied. From this result, The breakdown characteristics classify the gas & liquid coexisted stage of voltage value increases & much deviation and the $V_B$ low stage as the interior of chamber gets filled with mixture of $SF_6$ that are not liquefacted and remain ing air which couldn't be ventilated. In addition the ability of insulation of liquid $SF_6$ was higher than that of the highly pressurized $SF_6$ gas. In this research, we want to provide the base data on designing insulation of high-temperature superconductor and the cryogenic equipments by investigating the insulation characteristics of $SF_6$.
