New product innovation is a process of embodying new knowledge in a product and technology licensing is getting popular as a means to innovations and introduction of new product to the market in today's competitive global market environment. Incumbents often rely on technology licensing to access new product opportunities created by other firms. Prior research has examined various aspects of technology licensing agreements such as specific contract terms of licensing agreements, e.g., distribution of control rights, exclusivity of licensing agreements, cross-licensing, and the scope of licensing agreements. This study aims to provide answers to an important, but under-researched question: why do some incumbents initiate more licensing agreement for exploratory learning while others do it for exploitative learning along the innovation process? We attempt to extend our knowledge of licensing agreements from an organizational learning perspective. Technology licensing as a specific form of interfirm linkages can be initiated with different learning objectives along the process of new product innovation. The exploratory stages of the innovation process such as discovery or research stages involve extensive searches to create new knowledge or capabilities, whereas the exploitative stages of the innovation process such as application or test stages near the commercialization are more focused on developing specific applications or improving their efficiency or reliability. Thus, different stages of the innovation process generate different types of learning and the resulting technological resources. We examine when incumbents as licensees initiate more licensing agreements for exploratory learning objectives and when more for exploitative learning objectives, focusing on two factors that may influence a firm's formation of exploratory and exploitative licensing agreements: 1) its past radical and incremental innovation experience and 2) its internal investments in R&D and marketing. We develop and test our hypotheses regarding the relationship between a firm's radical and incremental new product experience, R&D investment intensity and marketing investment intensity, and the likelihood of engaging in exploratory and exploitive licensing agreements. Using data collected from various secondary sources (Recap database, Compustat database, and FDA website), we analyzed technology licensing agreements initiated in the biotechnology and pharmaceutical industries from 1988 to 2011. The results of this study show that incumbents initiate exploratory rather than exploitative licensing agreements when they have more radical innovation experience and when they invest in R&D activities more intensively; in contrast, they initiate exploitative rather than exploratory licensing agreements when they have more incremental innovation experience and when they invest in marketing activities more intensively. The findings of this study contribute to the licensing and interfirm cooperation studies. First, this study lays a foundation to understand the organizational learning aspect of technology licensing agreements. Second, this study sheds lights on how a firm's internal investments in R&D and marketing are linked to its tendency to initiate licensing agreements along the innovation process. Finally, the findings of this study provide important insight to managers regarding which technologies to gain via licensing agreements. This study suggests that firms need to consider their internal investments in R&D and marketing as well as their past innovation experiences when they initiate licensing agreements along the process of new product innovation.

Despite the fact that South Korea, one of peninsula countries, has been already a middle power in an international arena, it still tends to get stuck in continental-driven inertia and be reluctant to become a consolidated maritime power. In its efforts to deal with the parable of South Korea, designing a tailored-made strategy needs to be initiated in detail. Its design is centered around two variables: classification of waters and prestige. First of all, the domain of waters confronted to South Korea ranges from the greatest threat to scattered national interest. Second, South Korea is prestigiously regarded as the middle power which is equipped with the capability to see beyond its sovereign waters. The Maritime Access Strategy(MAS) can be more clearly explained by three-axis factors: ends, ways, and means. Ends need to be oriented to achieving three types of classified objectives-Deterrence, Engagement around the world to maximize remotely-scattered interest and Check of neighboring countries' seapower expansion, called DEC. Ways is mainly driven by the closer access to three different types of waters: waters of security, check, and interest. The active access and closer approach to the domain of waters need to be maintained with a high degree of willingness and capability. Means is attainable by guiding naval forces to be armed with multiple platforms and functionally-balanced assets. These platforms and assets will allow the naval forces to attain and maintain cost effective means, leading to making MAS feasible. This strategy allows the middle-power Korea to make the best of its maritime assets at various seas, contributing to international stability as well as national security and interest.

The objectives of this study are to identify the environmental consumer behavior, to examine the degree of environmental consumer behavior of the junior high school students, and to investigate the educational system of a school which influence the consumer behavior. The data used in this study are 368 male and female students in 9th grade in Anyang City, Kyunggi-do province. Statistics used for data analysis are means, standard deviation, t-test, and Multiple Regression Analysis. The results of the research are summarized as follows : First of all, as a tendency of the environmental consumer behavior of junior high students, the primary factor to the environmental problems was media, and among those, TV and radio was the medium to environmental problems. This implies the fact that the time juveniles interact with mass media is significantly growing, which means that transmitting environmental problems by programs targeted to adolescences through mass media would be effective. Next, the disposal process showed the highest environmental consumer behavior, followed by the consuming and purchasing process. Education on the purchasing process will be necessary to encourage environmental consumer behavior. The route of obtaining environmental knowledge was basically from school and the level of the average environmental knowledge fumed out to be low. This shows the need to produce and distribute media education materials because educating the conclusion of actual experiments will be more effective than that of theoretical studies. The conformity showed general indifference on environmental consumer behavior and the environmental resources were normally collected seperated. Conformity is a cultural bond teenagers think important, therefore education available for students about the same age should be developed. Next, the value intention of the surveyed showed that the ecological intention was highest, followed by economic and convenience intentions. This means the morale of the junior high students to environmental consumer behavior is set sound. Females tended to act more environmentally, while males showed more intention to economic causes. Also, the students of the boys-only or girls-only schools showed higher environmentally sound behavior in disposal processes. Finally, the environmental consumer behavior was influenced most by environmental consumer behavior of the conformity group, followed by ecological morale, frequency of encountering environmental problems, gender, environmental knowledge, whether the school was boys-only or girls-only or not, economical morale, respectively. The largest factor affecting the consumer activity of the purchase, consumption, and disposal process was environmental consumer behavior of the conformity group, along with the ecological morale, and the frequency of encountering environmental problems. This implies that conformity group is a large factor to the juveniles and a plan to entice the environmental consumer behavior of conformity groups are necessary.

Objectives: This study was conducted in order to examine the relationship between heavy metal concentrations in the soil and the level of heavy metals in the blood or urine of 216 local residents living near abandoned metal mines. Methods: Residents around abandoned metal mines were interviewed about their dietary habits, including seafood consumption, medical history, cigarette smoking, and drug history. Metal concentrations in the soil were determined by atomic absorption spectrophotometer (AA-7000, Shimadzu, Japan). Lead (Pb) and cadmium (Cd) contents in the blood or urine were analyzed by GF-AAS (AA-6800, Shimadzu). Mercury (Hg) contents in the blood were determined by means of a mercury analyzer (SP-3DS, NIC). Arsenic (As) content in the soil and urine were measured by a HG-AAS (hydride vapor generation-atomic absorption spectrophotometer). Results: The heavy metal concentrations in the soil showed a log normal distribution and the geometric means of the four villages were 8.61 mg/kg for Pb, 0.19 mg/kg for Cd, 1.81 mg/kg for As and 0.035 mg/kg for Hg. The heavy metal levels of the 216 local residents showed a regular distribution for Pb, Cd, Hg in the blood and As in the urine. The arithmetic means were 3.37 ${\mu}g$/dl for Pb, 3.07 ${\mu}g$/l for Cd and 2.32 ${\mu}g$/l for Hg, 10.41 ${\mu}g$/l for As, respectively. Conclusions: As a result of multi-variate analysis for the affecting factors on the bodily heavy metal concentrations, gender and concentration in the soil (each, p<0.01) for blood lead levels; gender and smoking status (each, p<0.01) for blood cadmium levels; gender (p<0.01) for urine arsenic levels; gender, age and concentration in the soil (p<0.01) for blood mercury levels were shown to be the affecting factors.

Background and Objectives : A post-pubescent male classical singer has lower vocal register than a female classical singer. Countertenors who can produce higher vocal register like female classical singers with their falsetto voice and head resonance are recently active. The general purpose of this study is to analyze voice of countertenors and to determine the differences with those of classical singers. Materials and Methods : Four countertenors in Korea were examined using a videostrobos-copy and their voice were analyzed using aerodynamic, acoustic and voice range profile methods. Results and Conclusion : Countertenors could produce elevated fundamental frequency, voice intensity and mean air flow rate using large pulmonary capacity and head voiced falsetto. It means the presence of greater energy in countertenor is due to the more efficient conversion of the air flow to acoustic energy. But, they had unstable amplitude perturbation per each vocal cycle. The results indicated that countertenor is the acoustic products of different laryngeal mechanism with other classical register and it can be recognized as one of the registers of male classical singers.

The purpose of the study was to evaluate the perception of importance about prerequisite program(PRP) of dietitians. A questionnaire was developed to achieve research objectives and sent to random samples of 450 dietitians by a mail from July to August in 2000 ; 242(54%) responses were analyzed. The respondents used three-point-scale to rate their perception of importance about PRP from 1-"will be necessary" to 3-"very important". All statistical analyses were conducted using SAS package(version 8.12) in order to have means, standard deviations, One-way analysis of variance, Duncan’s multiple range test and t-test. The study results were summarized as follows. The rates of perception of importance about PRP were significantly different from 21 of the 37 contents among business and industry, health care and school foodservice and were significantly different from 16 of the 37 contents among direct and contract management(p<.05 or p<.01 or p<.001). Dietitians in business and industry had lowest perception of importance about PRP of other respondents. Generally, the item related to ‘‘employee hygiene practice’ had the highest perception level score among PRP in foodservice facilities. Results indicate that there is a need for increased education of dietitians about PRP and appropriate practices.

Objectives : This study was to investigate the inhibitory effects of Ulmus davidiana on the generation of peroxynitrite $(ONOO^{-})$, nitric oxide (NO) and superoxide anion radicals $(O_{2}^{-})$ in the endothelial cells of rat vessels. The effects of Ulmus davidiana on the expression of inflammation-related proteins, $NF-{\kappa}B$ (p50, p65), COX-2, and iNOS, were examined by western blotting. Methods : For this study, fluorescent probes, namely dihydrorhodamine 123 (DHR 123), 4,5-diaminofluorescein (DAF-2) and 2',7'-dichlorodihydrofluorescein diacetate (DCFDA) were used. Western blotting was performed via using anti-$NF-{\kappa}B$ (p50, p65), anti-COX-2, and anti-iNOS, respectively. Results : Ulmus davidiana inhibited the generation of $ONOO^{-}$, NO and $(O_{2}^{-})$ in the lipopolysaccharide (LPS)-treated endothelial cells of rat vessels in vitro. Ulmus davidiana inhibited the expression of COX-2 and iNOS genes by means of decreasing the $NF-{\kappa}B$ activation. Conclusions : These results suggest Ulmus davidiana is effective on inhibiting the generation of $ONOO^{-}$, NO and $O_{2}^{-}$, and that therefore it might have a potential role as a treatment for the inflammatory process and inflammation-related diseases.

Multi-span steel-concrete composite (SCC) bridges are very sensitive to earthquake loading. Extensive damage may occur not only in the substructures (piers), which are expected to yield, but also in the other components (e.g., deck, abutments) involved in carrying the seismic loads. Current seismic codes allow the design of regular bridges by means of linear elastic analysis based on inelastic design spectra. In bridges with superstructure transverse motion restrained at the abutments, a dual load path behavior is observed. The sequential yielding of the piers can lead to a substantial change in the stiffness distribution. Thus, force distributions and displacement demand can significantly differ from linear elastic analysis predictions. The objectives of this study are assessing the influence of piers-deck stiffness ratio and of soil-structure interaction effects on the seismic behavior of continuous SCC bridges with dual load path, and evaluating the suitability of linear elastic analysis in predicting the actual seismic behavior of these bridges. Parametric analysis results are presented and discussed for a common bridge typology. The response dependence on the parameters is studied by nonlinear multi-record incremental dynamic analysis (IDA). Comparisons are made with linear time history analysis results. The results presented suggest that simplified linear elastic analysis based on inelastic design spectra could produce very inaccurate estimates of the structural behavior of SCC bridges with dual load path.

Objectives : Manufacturing and manipulation techniques of acupuncture can be interpreted as an induced electromagnetic viewpoint, as proposed in previous study. Considering from this point of view, the magnetization of needles should be essential to enhance the electromagnetic effects during the behavior of the acupuncture needling. Methods : The current disposable needles are made of non-magnetic stainless steels, so ferromagnetic materials were searched as suitable substitutes. Meanwhile, at the practical view, stainless steels are very available for the several superior properties like as corrosion resistance, strength, etc., magnetic stainless steels were first investigated. Some types of them still preserved the ferromagnetic properties of iron, so trial needles were made with them. And then magnetization of them were followed. Results : Among the hundreds types of stainless steels, martensitic or ferritic ones are ferromagnetic. The needles made with these ferromagnetic wires were magnetized, and polarized by magnetizer, and their magnetic properties were improved. Moreover, in addition to the superiority of the magnetism, the electrical and thermal conductivities of them were even better than those of the current austenitic stainless steels. Conclusions : Through the developmental study based on the electromagnetic viewpoint, the magnetized and polarized acupuncture needles were completed. This means that these needles having improved magnetism can be used to improve the electromagnetic needling effects, and moreover, their superiorities in the electrical and thermal conductivities can also give another benefits in treatments of electrical or warm needling.
