This paper presents the characteristics of fuel spray in a diesel engine. In this paper, in order to obtain spray droplet size in a diesel engine, water was injected into the cylinder at room temperature and pressure by injection system. Spray droplet size was measured by liquid immersion technique with a lubricant used as an immersion liquid for spray water from injection nozzle. In this experiment, single hole type throttle nozzle are used at same operating conditions, which included opening pressure of nozzle, fuel delivery, and injection speed. Sauter mean diameter decrease with the increase of injection pressure and decrease in injection nozzle diameter. The rate of spray penetration increased with increasing injection pressure and diameter of injection nozzle at the constant spray conditions.

II-A isotherms and phase behaviors of 'tocomide', a newly synthesized 1,3-bis(N-(2-hydroxyethyl)-tocopherol succinylamino)-2-hydroxypropane, mixed with cholesterol and linoleic acid, was studied for its monolayer miscibility and a stable delivery formulation for antioxidant applications. The monolayer of tocomide and cholesterol was formed in a homogeneously mixed state at air-water interface. The ternary mixtures with linoleic acid showed various bulk structures, including a stable and transparent solution of thermodynamically stable lamellar phase. The lamellar structure was confirmed by the X-ray diffraction (XRD) patterns and polarized microscopy such that pure tocomide formed a liquid crystal at room temperature with a lamellar periodicity of 36.7 $\AA$(2$\theta$=2.41$^{\circ}$).

In this study, the interfacial dielectric breakdown phenomenon of interface between Epoxy and Rubber was discussed, which affects the stability of insulation system of power delivery devices. The breakdown strength of specimens are observed by applying high AC voltage at the room temperature. The breakdown times under the constant voltage below the breakdown voltage were gained. As constant voltage is applied, the breakdown time is proportion to the breakdown strength. The life exponent n is gained by inverse power law and the long time breakdown life time can be evaluated.

The characteristics on the interface between Epoxy and EPDM which are materials of the underground insulation systems of power delivery have studied. The breakdown strength of specimens are observed by applying high AC voltage at the room temperature. The breakdown times under the constant voltage below the breakdown voltage were gained. As constant voltage is applied the breakdown time is proportion to the breakdown strength. The life exponent n is gained by inverse power law and the long breakdown life time can be evaluated. AC breakdown strength and life time is improved by oiling to the interface. When the low viscosity oil is spread interface has the highest life time.

This study used adult wistar-based rats to observe the sexual cycle as a morphological characteristic of vaginal epithelial cells by vaginal smearing, and investigated the fetal number through mating with male rats of the same strain. The target animal was a 12 to 13-week-old Wistar-based mature unlighted rat (weight 220 g to 240 g), room temperature 23 ± 2℃, 14 hours artificial lighting (05:00 to 19:00 hours), 10 hours Adapted individuals were used for rearing for at least 2 weeks under the conditions of the darkroom (19:00 to 05:00). The feed was managed for free feeding of pellet feed for animals and water. The vaginal smearing method was used for the experiments by observing the sexual cycle every morning and confirming that the normal sexual cycle of 4 or 5 days was repeated at least 2 cycles or more. As a result, the proestrus was found to have few red blood cells, the cells and nuclei were rather large and round, and many nucleated cells were identified. In the case of the estrus, the cells were large and the nuclei were not stained, and most of the keratinocytes were found. In addition, in the metestrus and diestrus, there were many white blood cells, and it was confirmed that nucleated epithelial cells and keratinocytes were significantly reduced. The pregnancy period was 21 ± 1.8 days, and the number of live births per delivery was 11.9 on average. The number of fetuses on the 8th and 10th days of pregnancy were 15.2 ± 0.4 and 15.4 ± 0.3, respectively. On the contrary, the number of fetuses on the 12th day of pregnancy was 12.9 ± 0.6, which was significantly (p < 0.05) decreased compared to the 10th day of pregnancy, and the number of fetuses was similar until delivery. As a result of investigating the change of body weight according to the birth weight and growth stage after delivery, the birth weight of female and male was 9.2 ± 2.0 g and 9.8 ± 2.5 g, respectively. After that, until the 16th day, the female and the male showed similarly moderate weight gain, and then showed a rapid weight gain until the 21st day of lactation. With reference to the results of this study, it is expected to be used as basic data for determining the mating time of rodents and controlling pregnancy and fetal number.

Purpose: This study was performed to establish the role and to analyze the job of MFICU (Maternal Fetal Intensive Care Unit) nurses using DACUM (Developing a curriculum). Methods: A DACUM workshop was held to define MFICU nurses' role and identify their duties and tasks. A DACUM committee was consisted of 7 nurses, 2 nursing professors and 1 medical doctor and as a result, a survey was developed which contained duties and tasks of MFICU nurse. Pre-test was carried out for the validity, finally collected the data from 97 nurses who worked at 7 MFICU and 10 delivery room. Results: A total of 60 duties, 115 tasks and 822 elements of tasks were defined on the DACUM chart and survey. The importance, frequency and difficulty of the tasks were presented the determinant coefficient (DC), the highest DC duty was 'Manage maternal ventilator' (15.09) and the lowest DC was 'Provide nursing care for leisure to gestation extension mother' (6.52). Twenty-eight tasks were differentiated between MFICU and delivery nurses significantly. And the most important, frequently, difficulty task perceived by MFICU nurse was 'Check fetal heartbeat with electronic fetal heart monitor'. Conclusion: The organized educational program and policy was needed to develop for MFICU nurses.

This study was designed to find the effect of Minocycline loaded microcapsule applied locally to tissue by measuring drug concentration in tissue and serum by HPLC and to achieve optimal drug delivery system and duration to a specific target site. Control group were administrated minocycline intramuscularly twice a day with $0.2{\mu}g/100g$ for 1 to 10 days. In experimental group, surgical wound was created on Rt. cheek and then minocycline loaded microcapsule was applied into the space between superficial and deep layer of masseter muscle. Animals were sacrificed at 1, 3, 5, 7, 10 days after initial administration, blood was obtained from heart and right masseter muscle was excised. Blood sample was centrifuged at 3000rpm for 15min. Tissue sample was homogenized, left at room temperature for 48hr and centrifuged at 4000g for 5min. Supernatant was completely dried and dissolved in distilled water. Analysis was conducted using a ${\mu}Bondapack$ C18 column. The mobile phase was 0.2M Ammonium Oxalate/0.1M EDTA/DMF=11/4/5 solution, which was injected into the column and detected with photodiode detector at 344nm wavelength. The results were as follows : 1. This method was reliable, could be replicated and suitable for minocycline analysis in tissue as well as serum. 2. In tissue, concentration of minocycline of experimental group was higher than that of control group for 5days. 3. Except 1 day, concentration of minocycline in serum of experimental group was lower than that of control group. 4. Concentration of minocycline in tissue was much higher than that in serum. From these results, minocycline loaded microcapsule might be effective tool for local drug delivery system might be useful for treatment of infections of oral and maxillofacial region and management of infected surgical wound, minimizing systemic effects.
