  • Drug intoxication in children and adolescents is not uncommon in Korea. But the tendency of intoxication is changing with some factors, such as national surveillance system, Naderism and increasing concern among physicians. But the death rate of intoxication among adolescents is increasing in spite of decreasing total death rate of intoxication among children and adolescents. Therefore the physician must be concerned about the basic management of intoxication and figure out the common toxic substance among children and adolescents.

  • Substance addiction is a chronically relapsing disorder that has been characterized by a vicious cycle composed of intoxication, craving/anticipation, withdrawal, and response inhibition/bingeing. Here we summarize the findings from neuroimaging studies in addiction according to these behavioral components and suggest the integrated neurobiological model of drug addiction and related brain correlates. The roles of various prefrontal regions, thalamus, memory circuit, anterior cingulated, and insula were also suggested in addition to those of classical mesolimbic dopaminergic system and its responsivity. Limited studies of behavioral addiction demonstrated a similarity with substance addiction on the neurobiological basis. Based on the current understanding of neurobiology of addiction, further researches on interactions of behavioral components and their brain correlates, behavioral addiction, and therapeutic applications will be desired.

  • In this paper, I tried to pursue health and social welfare together through medical convergence based on the main subject of a culture of convergence. Artists' drug accidents are never ending. Now Korea is also out of the drug cleansing country. it is impossible to get rid of them with the national public power. It is time for a treatment plan for these. They need a certain period of time and regular periods of rest and control over sports. Our humanities are researching to understand the changing human images of today. In parallel, medical convergence will also have to be transformed in various ways for human healing. Recently, we can see the case of healing with the combination of oriental medicine, natural healing and western medicine. Furthermore, the structure of medical convergence for the fight against disease can be analyzed as an example. South Korea is also preparing for various convergence programs focusing on natural sciences such as engineering, medical care, and the environment. In order to prevent drug addiction it is important to determine the department responsible for handling the problem of substance abuse. we need to improve the environment that they can be combined with Ondol therapy and natural healing therapies. Furthermore, I expect that fusion medicine will contribute to improving the quality of life of drug addicts and become a successful model to revitalize local economies in particular.

  • The possibility of using polypyrrole as a drug delivery system(DDS) has been studied using indicate (Phenol red) and substance with therapeutic activity(Sodium salicylate). In aqueous solution, negative potential is applied to polypyrrole then anion(with therapeutic activity) of sodium salicylate is released by redox processes of polypyrrole. The release amount of anionic drugs from polypyrrole is measured by UV-visible spectrometer which can measure UV-absorbance of materials. Electrode area that use for release amount measurement is$50mm^{2}(5{\times}10mm)$,and thickness of polypyrrole membrane is $15{\mu}m$. DC 1V applied in saline solution, the release amount according to time increased gradually. In various electrode area, release amount of anionic drug is directly to electrode area.

  • Objective : The purpose of this study was to lay the groundwork for understanding the details and scope of the legal definition of medicinal products, following the changes in the relevant laws and regulations. This will let readers properly understand the origins of the ongoing conflicts on herbal drugs and new drugs from natural products that are present in the medical field and the medical industry. Possible solutions are proposed in the end. Method : I analyzed the changes in definition of medicinal products since 1945 that have been used in relevant laws and regulations(i.e. Pharmaceutical Affairs Act) and drug approval process(i.e. New Drug Application and Investigational New Drug Application). Results : Legal definition of medicinal products has changed in accordance with the changes in the pharmaceutical industry, such as the establishment of dualistic medical and pharmaceutical System and the introduction of the substance patent. Due to those changes, boundaries of Western medicinal products and health food expanded, while those of herbal medicine products relatively downscaled. Conclusion : Legal definition of medicinal products-i.e. Herbal Drugs, Crude Drugs, and New Drugs from Natural Products-should be reestablished according to academic legitimacy and dualistic medical and pharmaceutical System.

  • This paper presents drug release properties of active drug delivery system (DDS) using volume change of polypyrrole (PPy). The incorporation of various chemical substances into the PPy and controlling its release with the externally applied voltage to the PPy are possible. In order to confirm possibility for drug delivery system qualitatively, indicator(phenol red) was examined as a dopant of PPy. The applied voltage to the PPy electrode was set to -2 V and this negative voltage makes the anionic indicator released in saline solution. After qualitative analysis, in order to confirm quantitative drug release characteristic of PPy, salicylate which is one of the aspirin substance was used as a dopant of PPy. As a result, the salicylate release characteristics with time was thoroughly investigated while varying the electrode area, polymerization time, the applied voltage for drug release. Based on these quantitative results, a preliminary experiment was carried out to check the feasibility of the PPy applicable to the neuronal system.
