  • In this paper, we introduce and study the generalized inverse $A^{(1,2)}_{T,S}$ with the prescribed range T and null space S of an adjointable operator A from one Hilbert $C^*$-module to another, and get some analogous results known for finite matrices over the complex field or associated rings, and the Hilbert space operators.

  • In presented paper there were studied some properties of Benford's law. The existence of this law in not necessary large sets of numbers is a very interesting example that can show how the complex phenomena can appear in the positional number systems. Such systems seem to be very simple and intuitive and help us proceed with numbers. However, their simplicity in the case of usage in our lifetime is not necessary connected with the simplicity in the case of laws that govern them. Even if this laws indicate the existence of self-similar properties.

  • The NADPH oxidase of phagocytes catalyzes the reduction of oxygen to $O_2^-$ at the expense of NADPH. The enzyme is dormant in resting neutrophils and becomes activated on stimulation. During activation, $p47^{phox}\;(\underline{ph}agocyte\;\underline{ox}idase\;factor)$, a cytosolic oxidase subunit, becomes extensively phosphorylated at a number of serines located between S303-S379. Oxidase activation can also be achieved by the addition of phosphorylated recombinant $p47^{phox}$ by protein kinase C in the cell-free system in the presence of $GTP{\gamma}S$. The cell-free activation is inhibited by wortmannin and LY294002. specific inhibitors of phosphatidylinositol 3kinase (PI 3-kinasel) These results indicate that PI 3-kinase may playa pivotal role in the activation of NADPH oxidase.

  • The seakeeping and resistance tests of a 47.7m class catamaran are conducted in a towing tank with the 1/21.5 scale model. The effect of the trim tab on the resistance is investigated with the trim tab angle variations and the resistance and trim angle of the catamaran with the trim tab are compared with those without the trim tab. The heave and pitch motions are measured at the three full scale speeds in sea state of 3.4 and 5 and the vertical accelerations at five points on the deck are also measured. The measured accelerations are compared with the criteria of ISO 2631/3 and it is shown that the seakeeping performance of the catamaran is good.

  • The purpose of this study is to investigate the cytogenetic characteristics of Down's syndrome in Korea. For this study, selected were 92 patients who were diagnosed as Down's syndrome by the chromosomal analyses, among 115 patients who were supected of Down's syndrome and referred to the Cytogenetic Laboratory, Institute of Reproductive Medicine and Population, Seoul National University, for 2 years from January 1984 to December 1985. Among 92 patients with Down's syndrome 83 (90.2%) had G-trisomy, 4 (4.3%) had translocation, and 2 (2.2%) had mosaicism of normal and G-trisomic cell lines. Two patients of the remaining 3 had both G-trisomic and translocation, 47, XX, t (1:21) (p32:q22), +21, 47, XX, t (9:11) (q34:q14), +21. The remaining 1 patient had 47, XY, +mar.

  • Objective : This study aimed to develop a Korean version of the HLS-EU-Q47 that deals with the concept of health literacy based on the understanding, apply/use, process/appraisal, and access/obtain to health information. The purpose of this study is to confirm the level of comprehensive health literacy of the elderly in Korea using this tool. Methods : After going through the Korean interpretation process of HLS-EU-Q47, the items were confirmed through content validity verification by experts. The completed Korean-HLS-EU-Q47 (K-HLS-EU-Q47) was applied to 254 elderly people in the local community to analyze the degree of internal consistency and reliability. Furthermore, a comparative analysis based on the general variables was conducted. Results : The internal consistency of this tool for the elderly yielded Cronbach's 𝛼 of .81~.91, indicating a high level of reliability. There was a difference in health literacy according to sex and age based on general characteristics. Men had higher health literacy than women, and with increasing age, health literacy decreased. Conclusion : In this study, the K-HLS-EU-Q47 was developed to assess the comprehensive health literacy level of the elderly in Korea. It is expected that the search for ways to maintain a healthier life for the elderly through understanding the health literacy levels of the elderly using the results of this study will become more active.

  • Objective : The present study examined the effectiveness of the mindful self-compassion (MSC) program on anxiety, depression, self-compassion and emotion regulation. Methods : A total of 29 subjects (mean age 27.5±6.5 years, 15 males and 14 females) participated in a standardized 8-week MSC program. The control group consisted of age- and sex-matched twenty participants (mean age 26.0±2.9 years, 11 males and 9 females). All subjects completed self-report measurements at two weeks before and after the MSC program. Results : MSC training improved self-compassion as demonstrated by the significant group x time interaction effects on the total Self-Compassion Scale scores (F[1, 47]=8.324, p<0.01). Regarding the subscale scores, a significant improvement in self-kindness, isolation and mindfulness components of self-compassion was observed after MSC training. A significant group x time interaction was observed on the self-kindness subscale (F[1, 47]=4.664, p<0.05), with a significant main effect of time (F[1, 47]=23.723, p<0.001). The isolation subscale showed a significant group x time interaction (F[1, 47]=8.698, p<0.001). For the mindfulness subscale, there was a significant group x time interaction (F[1, 47]=6.611, p<0.05) and main effect of time (F[1, 47]=6.611, p<0.05). MSC training also improved the acceptance emotion regulation strategy, as demonstrated by the significant group x time interaction in the acceptance subscale scores of the Cognitive Emotion Regulation Questionnaire (F[1, 47]=6.845, p<0.05). Conclusion : MSC training showed efficacy in fostering self-compassion and improving emotion regulation. Thus, this program might be applicable to improve mental health.
