The study was conducted to investigate the community structure of superfamily Cimicoidea (Geocorisae: Hemiptera) in Mt. Kyeryongsan from August, 1989 to August, 1990. The collected cimicoid insects were composed of 27 species, 16 genera, and 2 families. Composition of cimicoid insects found in each observed zone were 67.4% (22 species) in the paddy bank, 29.7% (21 species) in the weedy field and 2.9% (6 species) in the shrubs. Dominant species and Simpson's dominance indices were Ectmetopterus micantulus and Orius sauteri (λ=0.122) in the paddy bank, Halticiellus insularis and Halticiellus micantulus (λ=0.075) in the weedy field, Eurystylus coelestialium and Stenodema rubrinerue (λ=0.141) in the shrubs. Seasonal dominant species were Oriu sauteri and Polymerus (Poeciloscytus) unifascatus (λ=0.188) in Spring, Ectmetopterus micantulus and Orius sauteri (λ=0.137) in Summer, and Adelphocoris triannulatus and Trigonostylus coelestialium (λ=0.151) in Autumn. Species diversity indices (H') in paddy bank, weedy field, and shrubs were 1.049, 1.171, and 0.726, respectively. Eveness indices (J') were 0.781, 0.886, and 0.933, respectively. Community structures were almost similar between a paddy bank and a weedy field. 계룡산 지역에서 발생하는 빈대붙이상과의 군집분석을 위한 조사를 1989년 8월 부터 1990년 8월에 걸쳐 수행하였던 바 다음과 같은 결과를 얻었다. 채집조사된 빈대붙이상과는 2과 16속 27종이었다. 지대별 빈대붙이상과의 발생개체수 구성비율은 논뚝에서 67 4%(22종), 초지에서 29.7% (21종), 관목지에서 2.9%(6종)이었다. 지대별 우점종은 논뚝에서는 큰검정뛰어장님노린재와 애꽃노린재로서 우점도 지수는 λ=0.122, 초지에서는 검정뛰어장넘노린재와 큰검정뛰어장님노린재로서 λ=0.075, 관목지에서는 탈장님노린재와 홍맥장님노린재로서 λ=0.141였다. 계절별 우점종은 봄에는 애꽃노린재와 한띠장님노린재로서 λ=0.188, 여름에는 큰청정뛰어장님노린재와 애꽃노린재로서 λ=0.137, 가을에는 설상무늬장님노린재와 빨강촉각장님노린재로서 λ=0.151이었다. 다양도 (H')는 논뚝에서 1.049이고, 초지에서 1.171이며, 관목지에서는 0.726으로 나타났다. 균등도(J')는 논뚝에서 0.781이고, 초지에서 0.886이며, 관목지에서는 0.933으로 나타났다. 군집유사성은 논뚝과 초지간에 비교적 비슷했다.

In the industrial field, various type of fuel have been used for product processing facilities. Recent for 10 years, the usage of natural gas (NG) was gradually increased. Because it has many merits; clean fuel, no transportation, storage facility and so on. There are common safety concept that strict explosion protection approaches are needed for facilities where explosive materials such as flammable liquid, vapor and gases exist. But some has an optimistic point of view that the lighter than air gases such as NG disperse rapidly, hence do not form explosion environment upon release into the atmosphere, many parts has a conventional safety point of view that those gases are also inflammable gases, hence can form explosion environment although the extent is limited and present. In this paper, the heating equipments (Hot Oil Heater) was reviewed and some risk management measures were proposed. These measures include hazardous area classification and explosion-proof provisions of electric apparatus, an early gas leak detection and isolation, ventilation system reliability, emergency response plan and training and so on. This study calculates Hazardous Area Classification using the hypothetical volume in the KS C IEC code.

Primary Atrophic Rhinitis with Bilateral Turbinates Agenesis

장철,공원경 대한비과학회 2013 Journal of rhinology Vol.20 No.2

In this paper, we report a case of bilateral inferior and middle turbinate agenesis, a rare anomaly. A 27-year-old woman presented with nasal obstruction, crust formation, anosmia, and foul odors. Anterior rhinoscopic examination revealed the absence of the middle and inferior turbinates on both sides. The patient had no history of nasal or sinus surgery. She denied over having expelled anything of significance from her nasal cavity. She had no history of infectious disease-including tuberculosis and syphilis, granuolomatous diseases, sarcoids, Wegener's disease, and radiation therapy. There have been few reports on bilateral turbinate agenesis.

Laryngeal paragangliomas occur infrequently and are usually benign neoplasms. The overwhelming majority of these tumors are supraglottic, and submucosal lesions arise from the superior laryngeal parasympathetic paraganglia. MRI could find these lesions and evaluate vascularization of the tumor. It is important to distinguish between carcinoid, atypical carcinoid and medullary thyroid cancer. This can be done with histopathologic evaluation and immunohistochemical markers. Complete excision is recommended in the treatment of the tumor. We describe a case of a 32-year-old woman who had an laryngeal paraganglioma.

Background and Objectives:The most common cause of olfactory dysfunction is chronic rhinosinusitis, and endoscopic sinus surgery has been reported to yield beneficial outcome for the olfactory function. The purpose of this study was to study the benefits of endoscopic sinus surgery and investigate the influence of prognostic variables on the olfactory function in chronic rhinosinusitis patients. Materials and Method:We enrolled 52 patients who underwent endoscopic sinus surgery for chronic rhinosinusitis with olfactory dysfunction from July 2000 through April 2003 at Bundang CHA General Hospital, College of Medicine, Pochon CHA University. Patients were classified into 3 groups (well-healing, persistent olfactory disturbance and worse groups). We statistically compared various prognostic variables, such as CT scores, age, gender, allergy, duration of disease. and previous nasal surgery history among the 3 groups. KVSS test was used (Korean Version of Sniffin’ Sticks test) for the evaluation of olfactory function. Results:Of the prognostic variables examined, CT scores, gender, allergy, and duration of disease had no influence on the prognosis of olfactory improvement. However, old age and previous nasal surgery were found to have statistically significance on the worse prognosis. The olfactory function improved in 88% of the patients following the endoscopic sinus surgery. Conclusion:We concluded that olfactory function of many patients with conductive disorder improved after endoscopic sinus surgery. Gender, allergy, duration of disease had no singnificant influence on the prognosis of olfaction. The severity of sinusitis and the extent of polyps were not consistent with the degree of olfactory repairment.

This study is going to have been recognized a change of Cervical range of motion with the object 40 persons who sat for many hours before computer. According to the therapy term, sling used joint mobility exercise and Mckenzie was executed by 20 persons Shared. The study results about the effect that Cervical exercise had on joint Range of motion of a VDT syndrome patient were as follows. 1. There was a similar difference a sling used in Cervical Range of motion of joint mobility exercise cure after one-week, two-weet and three-week. 2. The change Cervical Range of motion of Mckenzie exercise has not been after one-week and two-week but a similar difference happens after three-week. 3. There has not been difference between joint mobility exercise and Mckenzie exercise in cure ferm sling used.

PURPOSE: In stroke patient rehabilitation therapy, visual perception disorder is an important factor to decide patient's ADL recovery and recuperation. METHOD: In this study, we studied what factors have effects on ADL performance ability to do stroke patient visual perception therapy on 36 university students and the 28 . ds. We use Dynavision set B-mode visual perception measurement and trainnig tool for 30 seconds at 5-second and 2-second intervals. We use only 4 rings among 5 ones. RESULT: It was resulted that womenls visual perception reaction velocity was a little bit faster when we compared womenls visual perception reaction velocity with menls and that it was faster at 2-second interval than at 5-second interval. In up and down space comparative, there's no significant contrast and in right and left space comparative, left's visual perception reaction velocity was faster than right's. CONCLUSION: We hope to you can use these results to improve stroke patient's ADL effect ability and to study visual perception therapy.
