Purpose: The purpose of this study was to investigate sales managers' strategic focus on customer acquisition, specifically its effect on salespeople's performance. In addition, this study aimed to determine how salespeople's interpersonal skills, salesmanship skills, and technical knowledge affect the relationship between customer-acquisition management and salespeople's performance. Research design, data, and methodology: This study conducted a survey of 310 salespeople working at pharmaceutical companies. A structural equation modeling approach was applied to test the main effects and interaction effects using AMOS. Results: The results indicated that both managers' customer-acquisition orientation and salespeople's salesmanship skills and technical knowledge positively affected the latter's performance. Further, it was found that the higher the technical knowledge of the salesperson, the greater the effect of the customer-acquisition orientation on sales performance. Conclusions: Sales managers should enable salespeople to quickly acquire technical knowledge with respect to the market, products, competitors, and company policy so that they can bring greater synergy to the customer-acquisition orientation.

This paper analyzed the impact of alliances on the market value of the 106 bio-pharmaceutical companies listed on the KOSPI or KOSDAQ in Korea by using the 'Event study methodology'. Although general alliances did not impact the corporate value significantly, in the analysis corresponding to the alliance type, R&D alliances created positive value, as technology acts as an important factor for the alliance. Among the R&D alliances, 'Technology Transfer alliances', in particular 'Development Technology Transfer alliances', had a positive influence on the corporate value. We interpret these differentiated results as market tends to screen for types of alliances. Meanwhile, we confirmed that the possibility of a stock price increase before the alliance announcement is high by analyzing the impact of the timing of corporate alliance announcements on the company value. It can be inferred that the possibility of information leakage is high. This paper analyzes the impact of alliances for managers and practitioners seeking to create value for domestic bio-pharmaceutical companies, and suggests the need to prevent information leakages by establishing a suitable policy.

In spite of many studies of The Korean Association of College of Pharmacy for improvement of the Korean pharmacy education and decrearing to change 4 year curriculum for pharmacy education to 6year curriculum from 1998 by The Ministry of Health and Wellfaire, there are many problems right now in view of the student-oriented education in front of the revolution program of The Ministry of Education. So the student-oriented reformation for pharmacy education in Korea was studied not only by observations of worldwide pharmacy education and pharmacy system, but also by 416 questionaires from many kinds of man and women such as pharmacists in drug store and hospital(159), administraters of The Ministry of Health and Wellfaire (59), professors in college of pharmacy (65), researchers in pharmaceutical company (31) and seniors in college of pharmacy(102).It shows that our Korean pharmacy education was a type of teacher-oriented education which is caused by the short time-education, a lots of subjects in the examination for pharmacy license and egoism of professors for their subjects, and so our teacher-oriented education have to change to the student-oriented education for the most function of pharmacist which is the pharmaceutical care for patients. For the preparing the clerkship/externship for one year, we have to change 4 year curriculum to 6 year curriculum for clinical pharmacy edu-cation, and also subjects of pharmacy in the national examination for pharmacy liciense have to reduce within 3-4 subjects of totally non-subject examination. The Korean Association of Collage of Pharmacy of Pan-pharmaceutical Revolution Association must purchase them and their program can be begun right now in spite of loss of the pharmacist supplement for 2 year and preparing the program of 6 years curriculum. Our teaching purposes of departments of pharmacy and manufacturing pharmacy were respectively clinical pharmacy, and development of new drug and compounding of many kinds of commercial drugs, but we have been not gone to their goals, respectively, because of short time-education for pharmacy as compared as world-wide pharmacy education containing the clerkship/externship and same twelve subjects in their examination for pharmacy license. Most function of pharmacist in Korea are the development of new drug, and social and administrative pharmacy in health care for patients, and so we have to teach them in the department of maunfacturing pharmacy.

Nucleocapsid protein (NP)which exists in the particle of hantavirus and surrounds the viral RNA genome is one of the major structural proteins and plays role of antigen to elicit the antibody detected predorminantly right after infection of the virus in the patients of hemorragic fever with renal syndrome (HFRS)or experimental animals. NP is important target antigen in serological diagnostic system of HFRS utilizing whole antigens from the native virus particle, such as IFA, ELISA and Western blotting. Therefore, the preparation of this protein in the level of higher quantity and purity is desirasble for developed dianosis of the disease. The purpose of this study is the cloning of NP gene which exists in the S genome segment of Maaji (MAA) virus and expression of the gene to obtain qualified, genetically engineered NP to be utilized as an immunodiagnostic antigen. First of all, for the purpose of amplifing the MAA-NP gene by PCR, the specific primers were built from the known nucleotide sequence of Hantaan viral NP gene. The viral cDNA of the NP gene was synthesized by using the primers and RNase $H^-$ AMV reverse transcriptase. Thereafter, using this cDNA as a template, the NP gene was amplified specifically by Taq DNA polymrerase. The pT7blue (R)T-overhang vector systems were used for cloning of the amplified NP gene. The expression system was consisted of BL21 (DE3)pLysS and pET16b as a host and a plasmid repectively. Into Ndel site of pET16b, NP gene was ligated with cohesive end for the expression. Insertion of NP gene in the plasmid was confirmed by PCR and mini prep methods. For expression, IPTG was used and the expressed protein was characterized by Western blotting. The MAA-NP was expressed as the form of inclusion body (insoluble fraction)and the protein purified by affinity and metal chealating columns reacted specifically with the sera from patients of HFRS as to be tested by ELISA and Western blotting.

Aceclofenac is an orally effective non-steroidal anti-inflammatory agent of the phenylacetic acid derivative. Bioequivalence study of two aceclofenac preparations, the test drug (Senafe $n_{R}$: Daewon Phar-maceutical Company) and the reference drug (Airta $l_{R}$: Daewoong Pharmaceutical Company), was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). Sixteen healthy male volunteers, 24$\pm$4 years old and 63.9$\pm$6.9 kg of body weight in average, were divided randomly into two groups and administered the drug orally at the dose of 100 mg as aceclofenac in a 2$\times$2 crossover study. Plasma concentrations of aceclofenac were monitored by HPLC method for 12 hr after administration. AU $Co_{-12h}$ (area under the plasma concentration-time curve from initial to 12 hr) was calculated by the linear trapezoidal method. $C_{max}$ (maximum plasma drug concentration) and $T_{max}$ (time to reach $C_{msx}$) were compiled directly from the plasma drug concentration-time data. Student's t-test indicated no significant differences between the formulations in these parameters. Analysis of variance (ANOVA) revealed that there are no differences in AU $Co_{12h}$, $C_{max}$ and $T_{max}$ between the formulations. The apparent differences between the formulations were far less than 20% (e.g., 0.25, 0.01 and 7.32 for AU $Co_{-12h}$, $C_{max}$. and $T_{max}$, respectively). Minimum detectable differences (%) between the formulations at $\alpha$=0.05 and 1-$\beta$=0.8 were less than 20% (e.g., 14.65, 12.47 and 15.46 for AU $Co_{-l2h}$, $C_{max}$ and $T_{max}$, respectively). The 90% confidence intervals for these parameters were also within $\pm$ 20% (e.g.,-10.19~10.68, -8.87~8.89 and -3.69~ 18.33 for AU $Co_{-12h}$, $C_{msx}$ and $T_{max}$, respectively). These results satisfy the bioequivalence criteria of KFDA guidelines, indicating that two formulations of aceclofenac are bioequivalent.quivalent.ivalent.ent.t.ent.

Natural product substances have historically served as the most significant also be prepared by source of new leads for pharmaceutical development. They can chemical synthesis(both semisynthesis and total synthesis) and have played a important role in the field of organic chemistry by providing synthetic targets. Rcently, they have also been extended for commercial purpose to refer to medicinal products, health functional foods, dietary supplements and cosmetics from natural sources. A large number of currently prescribed drugs have been either directly derived from or inspired by natural products. However, with the advent of robotics, bioinformatics, high throughput screening(HTS), molecular biology-biotechnology, combinatorial chemistry, in silico(molecular modeling) and other methodologies, the pharmaceutical industry has largely moved away from plant derived natural products as a source for leads and prospective drug candidates. The strategy for natural prduct industry is now changing from drug approaches to health foods by identifying effective natural products as preparations. In Korea, a lot of development of natural product based drugs have been done, but very few on health functional foods. The concept of natural product based health foods is not active components as lead compounds but standardized extracts or preparation mixed with other medicinal plants. The representative material has been recently known to be a standardized ginseng extract "Ginsana G 115" developed by Swiss Pharmaton company. The purpose of this presentation is to underline how natural products research continues to make significant contributions in the domain of discovery and development of new health functional foods. It is proposed to present the development of high value added health food or health functional foods through scientific investigation on efficacy and standardization of new materials form natural products.

Extracurricular activities are voluntary participations that students engage in outside of classrooms. This study aimed to determine Korean pharmacy students' degree of involvement in extracurricular activities, motivations behind participation, and influences from those engagements. The study was performed as a voluntary online survey to pharmacy students in four pharmacy schools in Korea and a total of 188 students participated. Sixty-one percent and 34% of students reported that they were involved in at least one extracurricular activities in-school, and out-of-school, respectively. Areas with most involvements were arts/music/sports (73%), followed by volunteer activities (31%). Thirty two percent responded that they have been involved in research internships, followed by 15% and 10% in pharmaceutical company and community pharmacy internships, respectively. For motivations behind involvement, students indicated that their involvement was for hobby (72%) and networking (38%). In conclusion, while Korean pharmacy students actively engage in extracurricular activities, the range of activities was limited in scope, and most students were involved in extracurricular activities as hobbies rather than for career exploration. Opportunities for student involvement in various pharmacy professional organizations and internships in the pharmacy work setting would provide valuable experiences for pharmacy students in their professional development as a pharmacist.
