  • Secondary metabolism in actinomycetes has been known to be controlled by a small molecule, ${\gamma}$-butyrolactone autoregulator, the binding of which to each corresponding receptor leads to the regulation of the transcriptional expression of the secondary metabolites. We expected that expression of an autoregulator receptor or a pleiotropic regulator in a non-host was to be gained insight of effective production of new metabolic materials. In order to study the function of the receptor protein (seaR), which is isolated from Saccharopolyspora erythraea, we introduced the seaR gene to Streptomyces coelicolor A3(2) as host strains. An effective transformation procedure for S. coelicolor A3(2) was established based on transconjugation by Escherichia coli ET12567/pUZ8002 with a ${\varphi}C31$-derived integration vector, pSET152, which contained int, oriT, attP and $ermEp^*$ (erythromycin promotor). Therefore, the pEV615 was introduced into S. coelicolor A3(2) by conjugation and integrated at the attB locus in the chromosome of the recipients by the ${\varphi}C31$ integrase (int) function. Exconjugant of S. coelicolor A3(2) containing the seaR gene was confirmed by PCR and transcriptional expression of the seaR gene in the transformant was analyzed by RT-PCR. In case of S. coelicolor A3(2), a phenotype microarray was used to analyze the phenotype of transformant compared with wild type by seaR expression. After that, in order to confirm the accuracy of the results obtained from the phenotype microarray, an antimicrobial susceptibility test was carried out. This test indicated that sensitivity of the transformant was higher than wild type in tetracycline case. These results indicated that some biosynthesis genes or resistance genes for tetracycline biosynthesis in transformant might be repressed by seaR expression. Therefore, subsequent experiments, analysis of transcriptional pattern of genes for tetracycline production or resistance, are needed to confirm whether biosynthesis genes or resistance genes for tetracycline are repressed or not.

  • The purpose of this study was to evaluate the validity of dental hygienist job according to judgment standard of medical practice in medical law. In this study, we conducted a self-administered questionnaire survey to evaluate the validity of dental hygienist job for 12 professors of dental college in Gangneung-Wonju National University from November 10 to 20, 2017. We investigated whether the dental hygienist job conforms to the three criteria of medical practice such as disease prevention and treatment, patient care, and health hazard. The response rates were scored and classified into four categories according to the final score. As a result of this study, dental hygienist job are classified into four categories according to judgment standard of medical practice. The higher the level of the category, the higher the degree of difficulty, and the higher the level of expertise and skills required. More than 50% of respondents answered that measuring the gingival pocket, bleeding on probing, professional tooth cleaning, oral health education, counseling after dental treatment are all three criteria for medical treatment. And these were classified into Level 4 group which requires the difficulty and expertise in the final score 4.3. It is necessary to develop and utilize standardized guidelines on the level of knowledge, education, and qualification standards required for dental practice in order to effectively allocate work among the dental personnel while ensuring the health rights of patients in the dental clinic field in Korea. In addition, there is a need to evaluate the various aspects of cost effectiveness, dental health service productivity, and health promotion contribution to dental hygienist jobs, And based on this evidence, it is necessary to continue to expand and adjust the dental hygienist job and to reorganize the dental workforce system.

Clinical Utility of the MMPI-A-RF's Internalization and Externalization Higher-Order Scales: Comparison With the K-CBCL's Internalization and Externalization Scales (MMPI-A-RF의 내재화 및 외현화 상위 척도의 임상적 유용성: K-CBCL의 내재화 및 외현화 척도와의 비교)

  • Objectives : The purpose of this study was to examine the clinical utility of the internalization and externalization higher-order scales of the Minnesota Multiphasic Personality Inventory-Adolescent Restructured Form (MMPI-A-RF), compared with those scales of the Korean Child Behavior Checklist (K-CBCL). Methods : 43 adolescents with internalizing disorders and 44 adolescents with externalizing disorders and their parents were administered the MMPI-A-RF and K-CBCL each. To verify the difference between the internalization and externalization scales of the MMPI-A-RF and K-CBCL for each group, independent-sample t test was performed. To compare the agreement between the MMPI-A-RF and K-CBCL, correlation analysis was also conducted. Lastly, to identify which scales significantly best predict each of the internalizing and externalizing disorder, logistic regression analysis was conducted. Results : Internalization scales of the MMPI-A-RF and K-CBCL were significantly higher in the internalizing disorder group, and the externalization scales were significantly higher in the externalizing disorder group. The positive correlation was significant only for internalization problems between the two evaluation measures in both groups (each r=0.360, p<0.05, r=0.572, p<0.05). In addition, the scales significantly predicted internalizing and externalizing disorders were the internalization and externalization scales of the MMPI-A-RF, followed by the externalization scale of the K-CBCL (R2=0.407, p<0.05). Conclusions : The internalization and externalization higher-order scales of the MMPI-A-RF were found to reliably reflect the characteristics of each disorder in adolescents and be useful evaluative scales to differentiate disorders. Moreover, if adolescents show externalization problems, additional information from the K-CBCL can be more useful to differentiate disorders.

A Study on "Reason and Madness" in Hegel's 『Phenomenology of Spirit』 - An Interpretation searching for the possibility of the dialogue between Hegel and Lacan - (헤겔 『정신현상학』에서의 '이성과 광기'의 문제 - 헤겔의 라캉과의 대화 가능성에서 본 하나의 해석 -)

  • The Law of the Heart, which appears in the chapter "B. The Actualization of Rational Self-consciousness Through its own Activity" in Hegel's Phenomenology of Spirit represents that the self-certainty of the reason may be the another face of the Madness. The Reason's indubitable certainty is the testimony of the truth for Descartes, and it also plays a role as the moral maxim of the conscience for Kant. But this subjective certainty unavoidably leads to the Madness of self-conceit, which unifies the consciousness and the reality ignoring the difference between them. The typical attitude appearing in the reformer like Don Quixote and also romantic idealists reveals the fact that modern reason and the psychosis can be both faces of one and the same coin. The Mirror Stage, the Imaginary, and the Formula of the Desire in Lacan's Theory shows that the Image of completeness is the result of Mis-understanding. Even if the Mirror stage is necessary for the Formation of the subject, at the same time it should also lead to the next stage, i.e., the Symbolic Order. It is considered as the realm of the Otherness, which refers to the realm of language or that of law. If the Ego can't go through the symbolic castration acted on by the Name of the Father, he will be remained in the prison of the Imaginary. The Madness also shows the similar process. For Hegel the Discipline of the Labor or the Death as absolute Otherness that inevitably delays the Desire plays the same role as the name of Father. It may be the experience of Separation or that of Sublation of the individual towards the universal, which is equivalent to the experience of Symbolic castration in Lacan. Furthermore there may be the difference between Hegel and Lacan as the following; while in Hegel the experience of Separation is founded on the spontaneity of the Spirit, for Lacan it is to be compelled and structured by the absolute Other.
