Purpose: This study empirically investigates the effect of collaborative communication and information sharing on the supply chain performance of South Korean pharmaceutical companies. Specifically, it understands the importance collaborative communication and suggests a method for investigating communication in academic research on the pharmaceutical industry. Investigating this sector is crucial because the importance of the pharmaceutical industry is increasing globally against the background of the Covid-19 pandemic. Research design, data, and methodology: A questionnaire was administered to employees of South Korean pharmaceutical companies and 244 valid responses were used for the statistical analysis. Additionally, structural equation modeling was used to measure the relationships between the observed and latent variables. Results: Collaborative communication has a positive effect on information sharing. However, information sharing, unlike collaborative communication, does not exhibit a significant positive relationship with supply chain performance. These results indicate that it is important to communicate effectively in the supply chain rather than strive for the right type of information sharing. Conclusions: Consumers and retailers within the supply chain should continue to strive for candid communication. This study is meaningful, as it empirically tests the relationships between collaborative communication, information sharing, and supply chain performance in the South Korean pharmaceutical industry.

Five crystalline forms of cimetidine, four anhydrous and a monohydrate, have been prepared, and their thermal behavriours have been studied by differential thermal analysis and thermo-gravimetry. The dissolution rates of the five forms were determined in distilled water at $37^{\circ}C$. The results showed a significant difference in the dissolution rate. Polymorphic transformation occurred spontaneously during storage at room condition and was accelerated by applied energy during formulation process-milling.

For the determination of aliphatic carbamates, the quantitative analysis of carisoprodol was investigated by gab chromatography (GC) and spectrophotometry. All the methods studied were found to be very quantitative. The minimum experimental amounts of GC method, spectrophotometric method I and II were approximately $10^{-9},\;10^{-5}$ and $10^{-8}$ mole, respectively. The obtained results showed that GC method I was much more sensitive and rapid than spectrophotometric method II.

Penicillin derivatives have a stability problem by hydrolysis of their .betha.-lactam ring. At high temperature, crystal water is released from penicillin derivatives, especially ampicillin trihydrate and concerns itself in hydrolysis. Penicillin derivatives having crystal water show different crystal states and different stability according to the variation of different condition on the process of manufacturing. The stability of ampicillin trihydrate in solid states was determined. Physico-pharmaceutical properties of this compound were determined by using IR spectra, X-ray powder diffraction and differential thermal analysis (DTA).

Analysis of particle size distribution of a sample of fine aluminum hydroxide powder was carried out by four different methods, i. e., conductivity, air permeability, gas-adsorption and sedimentation. Each method was reproducible. The results obtained by Coulter counter and sedimentation balance were similar, and the data obtained by Lea and Nurse permeameter and Stroehlein areameter were also similar. But the results differ considerabley between the former and the latter. The advantages and disavantages of each method were discussed briefly and a means of comparing the results with those obtianed by surface area measurements was shown.

Background: There is recent evidence that insulin resistance is responsible for increasing the risk of developing cognitive dysfunction. To systematically review the influence of intranasal insulin treatment on the cognitive function in Alzheimer's disease patients. Methods: Randomized controlled trials comparing the cognitive effects of intranasal insulin therapy in Alzheimer's disease patients with controlled interventions were retrieved from Pubmed, Medline, Embase and Cochrane library. Meta-analysis was conducted on the cognitive measurements with a subgroup analysis by dose, gender and apolipoprotein E allele 4 (ApoE ${\varepsilon}4$) status. Results: Seven randomized controlled trials were eligible for inclusion. Intranasal insulin had a positive influence on the cognitive function as compared to placebo without a statistical significance (standardized mean difference; SMD = 0.109; 95% confidence interval; CI -0.04 to 0.26; P=0.14). In subgroup analysis, a 20 IU dose of intranasal insulin induced a significant improvement in cognitive function (SMD = 0.14; 95% CI 0.05 to 0.24; P=0.004), but 40 IU did not show this effect (SMD = -0.01; 95% CI -0.11 to 0.09; P=0.82). ApoE ${\varepsilon}4$ positive patients showed a significant decline in cognitive function as compared to ApoE ${\varepsilon}4$ positive patients in the control group (SMD = -0.213; 95% CI -0.38 to -0.04; P=0.015). Such an effect was not apparent in ApoE ${\varepsilon}4$ negative patients. Gender had no influence on the cognitive outcomes. Conclusion: The results indicate that intranasal insulin may have beneficial effect in improving the cognitive function in Alzheimer's disease patients.

본 연구에서는 급진적 혁신을 수행하는 기업의 특징을 특허 데이터를 중심으로 살펴보았다. 1980년도부터 특허 정보는 기업의 성과를 측정하기 위한 중요한 지표로 활용되어 왔지만, 급진적 혁신을 대표하기는 어려웠다. 따라서 본 연구를 통하여 특허 집약 산업(Patent Active Industry)인 제약 산업에서 특허 정보가 급진적 혁신 지표로서 활용 될 수 있는지 알아보고자 하였다. 분석을 위해 약 10년간의 FDA 승인 데이터, 국외 기업의 특허 데이터를 활용하였으며 네트워크 중심성 분석(Centrality Analysis)과 비모수적 분석법인 윌콕슨 부호 순위 검정(Wilcoxon Signed Rank Test)을 실시하였다. 네트워크 분석 결과 급진적 혁신을 수행하는 기업의 경우 다른 기업들보다 대학 및 타 제약 기업과 협력 활동이 활발함을 시각적으로 확인 할 수 있었으며, 통계분석 결과 급진적 혁신을 수행하는 기업과 그렇지 않은 기업 간 연결 중심성(Degree Centrality)과 근접 중심성(Closeness Centrality)에 차이가 있음을 확인 할 수 있었다. 본 연구의 결과는 기업의 연구개발 전략 및 정책 수립에 활용 될 것을 기대하며, 향후에는 기업의 급진적 혁신에 영향을 미치는 요소가 무엇인지 정량 분석이 가능할 것이다.

This study was to investigate the relationship between the gel layer thickness and swelling boundary via strength measurements using texture analysis. The novel texture analysis approach was used to examine the dynamics of swelling behavior in a ternary polymeric matrix tablet. The method permitted the characterization of the changes occurring at the peripheral as well as within interior boundary of the swelling during water ingress. The increase in gel strength for pectin, HPMC, and a ternary mixture with gelatin was found to depend on polymer concentration. Therefore, this method is further applicable to characterize the swelling behavior and provide opportunity to differentiate the gel-layer from that of swelling boundary.

Objectives: To provide guidance for agency planning by identifying barriers faced by Korean pharmaceutical companies in global regulatory affairs. Methods: A questionnaire survey on global regulatory affairs was administered by email to personnel at Korean pharmaceutical companies. From a total of 60, 28 responses were collected. Respondents' companies were classified as small-sized or large-sized, based on whether their annual sales amounted to KRW 100 billion. Results: Small-sized companies were experiencing greater difficulties in receiving drug approvals from advanced countries, particularly during the Investigational New Drug (IND) and Good Manufacturing Practice (GMP) processes. Conclusions: Support measures to specifically help small-sized companies enter more advanced markets and further improved global regulatory guidelines that can meet large-sized companies' expectations are needed. Moreover, domestic and global regulatory standards should be harmonized to benefit both groups.

Cost containment has become high political issues since financial crisis of the Korean Health Insurance fund in 2000. Korean Government has developed and implemented several measures to reduce the pharmaceutical expenditures. Pharmaceutical economic evaluation can be a tool in decision to allocate scare resource efficiently. In order to increase the quality of economic evaluation for pharmaceuticals, the Korean Health Insurance Review Agency(HIRA) is considering the development of a guideline for economic evaluation. It mandates that pharmaceutical companies could submit the result of an economic evaluation when demanding reimbursement of new pharmaceutical drugs. The purpose of this study is to provide a critical review of the economic evaluations of health care technologies published in the Korean context whether they have been performed according to current guidelines and therefore whether their results are directly useful for decision making. We found there exist important problems and deviation from, good practice' both in the general features of the studies, like the study design and perspective, and in terms of cost measurement and valuation. There are needs to develop clear guidelines and to educate and train researchers in performing economic evaluations.
