The 1,3-bis(4-aminoaryl)squaraines showed colour change behaviour, they were found to undergo reduction with sodium borohydride in solution to give colourless leuco compounds, which oxidised readily in air back to the coloured squaraine dye. We have shown that oxidation of the parent leuco-squaraines gives the neutral squaraine system. Initial observations indicated that the derivatives gave new long-wavelength absorbing chromophores, and It is interesting to note that the onidation of the leuco squaraines did initially produce a species absorbing at longer wavelengths than the parent squaraine dye. This colour-change redox behaviour has potential in the area of peroxidase-based bioassays and artificial camouflage.

The effect of chemically oxidized intermediates of Polynuclear Aromatic Hydrocarbon (PAH) compounds on the degradation of the parent PAHs was characterized and evaluated for the context of cooxidation. Anthracene and pyrene exhibited extensive degradation (mean percent removal of 57.5%) after 28 days of incubation by introducing the Fenton oxidation intermediate of the PAH compounds, while unoxidized anthracene and pyrene exhibited 12.5% removal The chemical oxidation products can serve as a structually similar analogue substrates for a consortia of soil microorganisms and as a metabolic intermediates in the biodegradation sequence of the parent PAH compounds. These results may be interpreted in the context of cooxidation mechanism whereby high recalcitrant PAH compounds are biodegraded in the soil and suggest a potential tool for bioremediation of PAHs contaminated soils and protection of groundwater.

Purpose: The current descriptive study examined the health and healthcare status of preschoolers in poverty group compared to those of comparison group. Method: Data were collected from 51 mothers in federal poverty group and 49 in low-income group and 200 mothers in normal income comparison group in one city. The instruments used for this study were Korean CBCL and health related questionnaire. Results: Public assistance group showed more low-birth-weight infants, developmental delay, and hospital admission experiences. Their compliance for vaccination and congenital metabolic disorder test were lower than those of comparison group. Preschoolers' behavior problems were not significantly different depending upon the income of the group. Conclusion: Preschoolers' health and healthcare status are affected by the socioeconomic characteristics of the family. It indicated an need for anticipatory guidance and early intervention that might help to prevent or ameliorate potential health problems in poverty.

Purpose: The aim of this study is to suggest a direction for the development of effective methods for relieving labor pain, by analyzing non-pharmacological interventions through a literature review. Methods: Collection of literature data in this study has been accomplished through theses, reports, and academic data searched on databases of the Research Information Sharing Services (Riss), PubMed, ProQuest, and the National Discovery for Science Leaders (NDSL). Results: Non-pharmacological interventions analyzed as effective in relieving labor pain, in literature published both within and outside of Korea, included: pre-delivery education, Yoga, Doula delivery care, Massage, Music therapy, Aromatherapy, Hypnosis, TENS, Sterilized water injection, and Acupuncture. Conclusion: Several different interventions have been attempted for the relief of labor pain. Since even the same intervention shows different results depending on the research method utilized, critical factors must be acknowledged that compromise the effectiveness of these methods. In addition, study of potential synergy effects of interventions that combine these various methods might also prove to be significant.

Pivaloyloxymethyl ester of cefoperazone was synthesized by treating sodium cefoperazone with chloromethyl pivalate and its chemical structure was determined by spectroscopic trials. The pharmaceutical properties of the ester were investigated to assess its potential as a prodrug of cefo perazone. Cefoperazone pivaloyloxymethyl ester was microbiologically inactive itself in vitro, but hydrolyzed into the parent drug in vivo. After a single oral dose of each drug to rabbits, serum concentrations of cefoperazone were determined by high performance liquid chromatographic assay. The ester showed higher and more sustained blood level than cefoperazone. Therefore, the total area under the serum concentration-time curve of the derivative was 16.8 times larger than that of the parent drug.

The effect of chemically oxidized intermediated of PAH compounds on the degradation of the parent PAHs was characterized and evaluated for the context of cooxidation. Anthracene and pyrene exhibited extensive degradation (mean percent removal of 57.5%) after 28 days of incubation by introducing the Fenton oxidation intermediate of the PAH compounds, while unoxidized anthracene and pyrene exhibited 12.5% removal. Dehydrogenase activities for the oxidized PAH studies ware enhanced two to five folds to the unoxidized PAHs studies. The chemical oxidation products can serve as a structually very similar analogue substrates for a consortia of soil microorganisms and as a metabolic intermediates in the biodegradation sequence of the parent PAH compounds. These results may be interpreted in the context of cooxidation mechanism whereby high recalcitrant PAH compounds are biodegraded in the soil and suggest a potential tool for bioremediation of PAHs contaminated soils and protection of groundwater.

Objectives : The goal of the surgical management of large and giant aneurysm is complete extirpation of the aneurysms with preservation or reconstruction of the parent artery. To improve the surgical management results of those aneurysms in the future, we review our experience and discuss technical maneuvers and strategies used to avoid potential complications of those aneurysm surgery. Material and Methods : During the past 12 years, thirty six cases of large and giant aneurysms(diameter>19mm) were managed by surgery. The clinical characteristics, treatment methods, surgical complications and outcome of those cases were analyzed and, based on the review of the literatures, the preventive methods of surgical complication related to the clipping of those aneurysms were discussed. Results : The locations of those aneurysms were anterior circulation in 34 cases and posterior circulation in 2 cases. The most frequent site of aneurysmal location was a paraclinoidal region of the anterior circulation. The aneurysms were managed surgically by direct clipping of aneurysmal neck in 31 cases, aneurysmal trapping followed by extracranial-intracranial bypass in 2 cases, proximal clipping of parent artery, aneurysmorrhaphy, and excision of aneurysm followed by end to end anastomosis of parent artery in each one case. Surgical complications occurred in 13 cases. A parent vessel occlusion by thrombus formation and parent vessel stenosis after clipping of aneurysm were the main complications. We obtained good outcome in 27, fair 5, poor 1 and dead in 3 case(s). Conclusion : We conclude that selection of suitable management method for each case, high quality of surgical technique and prevention of complication during operation are important key points for the successful treatment of large and giant aneurysm. The heparinization prior to application of temporary clip on parent vessels, aneurysmal decompression during dissection and clipping of aneurysm, complete closing of the aneurysmal neck and avoiding the narrowing of parent vessel after clipping of aneurysm were the main technical maneuvers used to avoid complications of those aneurysm surgery.

Purpose: In this study, the Internet game addiction level was assessed, and parent-child attachment level associated with the addiction was analyzed. Method: From December 5 to 23, 2005, self-reported questionnaire data were collected from 990 Busan City elementary school students of the 5th and 6th grades. The questionnaire consisted of questions about their characteristic features in playing Internet games based on the K-scale developed by KADO. The data were analyzed using the SPSS WIN 10.0 program. Frequency, percentage, arithmetic mean, and standard deviation, $X^2$-test, ANOVA analysis and Scheffe test were used to analyze the data. Results: 1. With regard to the level of Internet game addiction, 71.2% of the students responded that they were general users, and 6.3%, at high risk for addiction. Mean scores were 103.3 for the high-risk group, 77.7 for the potential risk group, and 55.86 for the general user group. The total mean was 63.74. 2. Mean scores for parent-child attachment levels were 97.1 and 99.6 for father and mother, respectively. Conclusion: These results suggest that a collaborative program to educate and counsel parents to increase the parent-child attachment level needs to be established in protection and recovery programs for Internet game addiction.
