Objective: This study evaluates the effects of traditional Korean medicine (including Guibi-tang) on a psychogenic urinary incontinence patient with hypersomnia disorder.Method: Herbal medicine, acupuncture, and moxibustion were carried out. The effect of the treatments was then evaluated via the Beck depression inventory (BDI), the Beck anxiety inventory (BAI), the symptom checklist-90-revised (SCL 90-R), the Epworth sleepiness scale (ESS), and the revised urinary incontinence scale (RUIS), as well as the number of urinations, incontinence levels, and sleeping times during the day.Results: After the treatments, both the urinary incontinence and hypersomnia symptoms showed improvement.Conclusion: This study suggests that traditional Korean medicine treatments are effective in caring for patients who suffer from psychogenic urinary incontinence with hypersomnia disorder.

The plunging ranula or cervical ranula is amucous extravasation cyst of the sublingual gland. It is slightly common in females, shows no side preference, and is more prevalent in the second and third decades of life. It typically manifests as a painless, nonmobile swelling in the neck. The pathogenesis of plunging ranula is the discontinuities of the mylohyoid muscle in a position that would allow extravasation of sublingual gland mucin. The histologic appearance is characteristically of a cyst, devoid of epithelium or endothelium, with a vascular fibro-connective tissue wall containing some chronic inflammatory cells and macrophages stuffed with mucin. The correct diagnosis is essential for the most effective treatment, which is exicision of the sublingual gland. The plunging ranula must be differentiated clinically and histomorphologically from thyroglossal duct cyst, dermoid cyst, branchogenic cyst, lymphangioma, laryngocele, lipoma, hemangioma, cervial thymic cyst, cysts of the parathyroid or thyroid gland, lymphadenopathy, abscess, or tumor. We report a case and review the literatures, in our case, 23-year old man were diagnosis as plunging ranula after have been taken sialogam, MRI, etc. He underwent surgery via a cervical approach. The ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle. A pseudocyst was extirpated. Although total sublingual gland excision was not performed, no recurrence was observed during 6 months follow-up periods.

In PRAM applications, the devices can be made for both binary and multi-state storage. The ability to attain intermediate stages comes either from the fact that some chalcogenide materials can exist in configurations that range from completely amorphous to completely crystalline or from designing device structure such a way that mimics multiple phase chase phenomena in single cell. We have designed stack-structured phase change memory cell which operates as multi-state storage. Amorphous $Ge_xTe_{100-x}$ chalcogenide materials were stacked and a diffusion barrier was chosen for each stack layers. The device is operated by crystallizing each chalcogenide material as sequential manner from the bottom layer to the top layer. The amplitude of current pulse and the duration of pulse width was fixed and number of pulses were controlled to change overall resistance of the phase change memory cell. To optimize operational performance the thickness of each chalcogenide was controlled based on simulation results.

we have studied characterization of microbolometer based on the co-sputtered silicon-antimony ($Si_{1-x}Sb_x$) thin film for infrared microbolometer. We have investigated the resistivity and the temperature coefficient of resistance (TCR) with annealing. We deposited the films using co-sputtering method at $200^{\circ}C$ in the Ar environment. The Sb concentration has been adjusted by applying variable DC power from Sb targets. TCR of deposited $Si_{1-x}Sb_x$ films have been measured the range of -2.3~-2.8%/K. The resistivity of the film is low but TCR is higher than the other bolometer materials. Resistivity of the films has not been affected hugely according to the low annealing temperature however the resistivity has been dramatically decreased over $250^{\circ}C$. It is caused of a phase change due to the rearrangement of Si and Sb atoms during crystallization process of the films.

칼륨과 티타니아 담체가 일산화탄소 수소화 반응에서 분자량이 큰 불포화 탄화수소의 합성에 유리할 것으로 예상하여, 칼륨염이 첨가된 티타니아 담지 코발트 촉매를 제조하여 일산화탄소 수소화 반응에 사용하였다. 칼륨과 티타니아 담체는 일산화탄소 수소화 반응에서 분자량이 큰 불포화 탄화수소 화합물을 합성하는 데 있어 중요한 역할을 하였을 뿐 아니라, 탄소 누적에 의한 촉매의 비활성화 방지에도 기여하였다. 이는 티타니아 담체가 코팔트 금속과 강한 상호작용을 하고, 칼륨은 코발트 금속에 전자를 풍부하게 하는 전자 공급자로 작용하여 일산화탄소의 흡착력을 증가시켰기 때문으로 믿어진다. Small amounts of potassium were added to the titania - supported cobalt catalysts in order to produce higher and olefinic hydrocarbons in CO hydrogenation. Titania and potassium played important roles not only for the enhancement of the production of higher and olefinic hydrocarbons, but also for the prevention of the catalyst deactivation by carbon deposits. Titania support induced the so - called SMSI, and potassium seemed to act as an electronic modifier, giving rise to an electron enrichment of the metallic phase.

The intentional objective which it sees to lead and The Southerners, Northerners when it is a rotation yearly work novel of Lee Ho-Chul actual confrontation aspect of the process where in the center the experience of the author is transfigured with novel subject and an author ceremony the subject which appears in work inside to examine closely. It sees hereupon and the experience of the author whom it boils leads and novel composition principle it investigates the process which is transfigured from novel, comparison it analyzes the ceremony of subject and the author. Lee Ho-Chul was the literary applicant who is born from the household where the traditional culture of North Korea continued. It was caused by but by socialistic revolution and Lee Ho-Chul was mobilized in the north army, Lee Ho-Chul‘s household confiscation of property and it was expelled from hometown all. The socialistic revolution literature and property, three branches which the hometown back are important goes in him. The subject of novel loses and him against three branches which it throws away the opposing form which is envy and resentment it shows. Like this actual confrontation aspect of subject the rationality compared to is a possibility relatively the sensitivity knowing. Description of the author depended the objective situation recognition than in sentiment and the ceremony of subject and the author agreed all. Is like that The Southerners, Northerners Lee Ho-Chul stain position Korean history which is unhappy experience of oneself is the work which in the center it describes with appreciation in tragedy of Western ideology and fratricidal war. Despite The Southerners, Northerners is treating the time of agitation and sorrow who is radical it dozes but about the reason where the wail which is miserable does not come out is to. Author ceremony of The Southerners, Northerners it appeals the pain of the individual from historical inside, compared to is a place where it shows the development process of history concretely.
