디자인의 동일 또는 유사 여부 판단

박종학(Jong Hak Park) 세창출판사 2010 창작과 권리 Vol.- No.60

Modern society is product-oriented one. Various products that are manufactured and sold stimulate consumers' desire. Hence, the manufacturer tries to make products that are equipped with beautiful appearance as well as excellent quality and functions. For consumers, who want to express their personalities through their products as a total fashion, regards a design on their products as an important decision factor for buying the products. This design is created from constant research and efforts, not naturally. Strong legal protection for the design is required because the design, which is difficult to be created, is easy to be copied. Therefore, design protection law tightly protects an issued design: applied designs which is same and similar with publically-known, publically-used ones are denied due to lack of novelty. In this context, it is important legal issue to determine whether the compared designs are same or similar each other because this sameness or similarity is used when determining novelty of design, pre-application, expanded pre-application. Also, they are used when determining the scope of the issued design's right and protection. It is highly important to legal theory and solution for legal dispute to study on the criteria of design's sameness and similarity, which is the most important factor for design protection. In addition, more understanding for new cases is required in the legal system of design protection law and intellectual property law. Also, more leading cases, which do not harm legal stability and seek detailed plausibility, are needed to be settled.

Tramadol HCl(TH)-loaded poly(L-lactide-co-glycolide)(PLGA) microspheres were prepared by O/O solvent evaporation method for sustained release. We investigated the release behavior according to PLGA molecular weight and concentration. TH-loaded PLGA microspheres were characterized on the surface and cross-section morphology by SEM. TH-loaded PLGA microspheres had smooth surfaces and various pores in internal structure. As the PLGA molecular weight and PLGA concentration increased, the release rate of TH decreased. The behaviors of degradation was decreased according to increased PLGA molecular weight. These results showed that the release behaviors can be controlled by various of molecular weight and concentration of PLGA.

Purpose: In Korea, most abdominal penetrating wounds are caused by stab wounds rather than gun-shot wounds. However, not many studies have been performed on stab injuries and their epidemiologic characteristics. Disagreements of opinions of obligatory surgical exploration and conservative treatment exist, and this subject is still being debated. Therefore, the authors studied the epidemiologic characteristics of abdominal stab wound patients visiting the emergency department and reviewed the proportion of patients that received nontherapeutic surgery and conservative treatment. Methods: This study included patients visiting the emergency department with abdominal stab wounds. A retrospective chart review was done on the abdominal stab wound patients. Sex, age, cause of injury, location of wound, initial vital signs, operation results, injured organs and CT & LWE results were reviewed. Results: The median age of the 121 patients was 40.9 years, of these patients, 88 were males, of which 52 (43.0%) were drunken. Of the patients that received non-therapeutic operations, only 3 patients (15.0%) were drunken, significantly lower than the therapeutic operation group. For the location of the wound, most patients were injured in the right and left upper quadrants, 27 patients each. The most common injured organ was the small bowel; 13 patients were injured in the small bowel. With abdominal CT scans and local wound explorations together, the results exhibited a sensitivity of 97%, a specificity of 44%, a positive predictive value of 56%, and a negative predictive value of 95%. Conclusion: In our study, the sensitivity was 97% when CT & LWE were performed together; thus we can conclude that CT and LWE can be used together to select the treatment method. Although in our study, the surgical indications in abdominal stab wound patients is not sufficient, our results showed a higher rate of nontherapeutic surgery compared to previous studies. Therefore, more research is needed to prevent unnecessary laparotomies in hemodynamically-stable patients without symptoms. (J Korean Soc Traumatol 2010;23:21-28)

The aim of this study was to improve dissolution rate and controlled release of poorly water-soluble drug, cilostazol, using general water soluble polymers. We prepared solid dispersed cilostazol with hydrophilic polymer, Poly-N-Vinylpyrolidone(PVP), Plasdone S630, Hydroxypropylmethylcellulose(HPMC), PEG 6000, Eudragit E100, and surfactant, Poloxamer 407. Characterization of cilostazol solid dispersion analyzed by scanning electron microscope(SEM), differential scanning calorimeter(DSC) and infrared spectrometry(FT-IR). SEM and DSC were found that amorphous in solid dispersion. Particle size analyzer was used to investigate size of cilostazol in solid dispersion. The in vitro release behavior of solid dispersion presented at simulated gastric fluid(pH 1.2). The release behavior of cilostazol was controlled release with hydrophilic polymers and solid dispersed cilostazol with hydrophilic polymers was sustained release behavior than initial burst release of commercial drug(Pletal(R)). This studies suggest that this solid dispersion system with hydrophilic polymers controlled poorly water-soluble drug, cilostazol, release behaviors.

Collaborative filtering recommends products using customers’ preferences, so it cannot recommend products to the new customer who has no preference information. This paper proposes a novel approach to new customer recommendations using the social network analysis which is used to search relationships among social entities such as genetics network, traffic network, organization network, etc. The proposed recommendation method identifies customers most likely to be neighbors to the new customer using the centrality theory in social network analysis and recommends products those customers have liked in the past. The procedure of our method is divided into four phases:purchase similarity analysis, social network construction, centrality-based neighborhood formation, and recommendation generation. To evaluate the effectiveness of our approach, we have conducted several experiments using a data set from a department store in Korea. Our method was compared with the best-seller-based method that uses the best-seller list to generate recommendations for the new customer. The experimental results show that our approach significantly outperforms the best-seller-based method as measured by F1-measure.

In this study, sibutramine HCl, appetite suppressants were prepared into tablet type with additives such as lactose monohydrate, microcrystalline cellulose(MCC), and PVP K-25 to effective oral administration. We used the polyplasdone XL-10 as disintegrant. We compared the in vitro release behavior of sibutramine from the tablets according to additives with commercial drug, Reductil. The change of structure and crystallinity of tablet by additives were characterized by fourier-transform infrared spectroscopy(FT-IR) and differential scanning calorimeter( DSC). FT-IR and DSC results demonstrates that structure of drug was changed and crystallinity of drug was decreased according to additives. The dissolution rate of sibutramine HCl from tablet greatly increased in simulated gastric fluid(pH 1.2) and simulated intestinal fluid(pH 6.8) in case of adding lactose monohydrate and PVP K-25. This study suggest that various pharmaceutical excipients could improve the sibutramine HCl release behaviors.
