플라워샵 경영주를 대상으로 한 주요 절화류의 용도별 이용성과 장래성에 대한 조사연구
허북구,윤재길,강호종,박상현 진주산업대학교 2001 論文集 Vol.40 No.-
Survey for utilization, future availability and demand prospect of 32 cut flowers on 120 flower shop owners was conducted. On the utilization for purposes, out of 32 cut flowers surveyed, cut flowers evaluated as more than 'good' were 15, 14 and 12, in for flower basket, bouquet and home, respectively. Flowers evaluated as less than 'medium' were just 1-2 kinds including standard chrysanthemum. For event decoration and religion, 5 and 8 cut flowers were evaluated as more than 'good'. For consolation garland, celebration garland and bridal bouquet, just 1, 6 and 7 plants were evaluated as more than 'good'. These results indicated that utilization of cut flowers were largely different according to their use purposes. On the future availability, all 32 cut flowers were evaluated as more than 'good' in for religion. Almost plants were evaluated as more than 'medium' excepting standard mum and gerbera in for home, standard mum and china aster in for celebration garland, standard mum in for flower arrangement, houquet, flower basket and event ceremony. However, for consolation garland, just 7 plants including standard mum were evaluated as more than 'medium'. For bridal bouquet, just 5 plants including rose were evaluated as more then 'good'. The importance for purposes of cut flowers is orderly for flower basket > bouquet > celebration garland > consolation garland > bridal bouquet > flower arrangement > event decoration. The demand prospect for purposes of cut flowers was evaluated as more than high in for flower basket and bouquet, as more than medium in for event decoration, home, flower arrangement and religion, and as less than medium in for celebration garland.

Partial or complete arrest of root formation is a rare complication caused by different factors that affects the permanent tooth during root development. The possible factors affecting this complication have been reported in dentin dysplasia, trauma, transmission of the periapical infection of the primary teeth to permanent tooth germ, radiation therapy, and congenital renal disease. One of these factors, traumatic injury to the primary dentition may cause a deflection or displacement of the permanent tooth bud. And the effects of trauma to Hertwig's epithelial root sheath which is essential to root development are the result of the transmission of the traumatic force through the surrounding bone or through the primary tooth. And it can cause critical damage to the normal root development. These tow cases show 2 children who complained of delayed eruption of permanent incisors, who have had a traumatic history during primary dentition. After clincial examination, because they have no more evidence of root formation of maxially lateral incisors. We extracted the permanent maxially lateral incisors which show partial or complete arrest of root formation. We concluded as follows; 1. These two cases show that one is a complete arrest of root formation when injured at 3 years old, the other is a partial arrest of root formation when injured at 5 years old. So, it is considered that direction and magnitude of traumatic forces and injured stage of permanent tooth bud will affect the root development. 2. It was noticed that there was an arrest or loss of Hertwig's epithelial root sheath in the histologic section of the extracted maxially lat. incisors. 3. After continuous observation, if there is a sign of partial or complete arrest of the root formation, impaction, or delay of the eruption of surrounding teeth after the normal root formation stage, extraction is indicated, and it is considered that orthodontic or prosthodontic treatment is needed.

Mucocele is clinical term used to describe swelling caused by the pooling of saliva at the site of a severed or obstructed minor salivary gland duct. Two types are recognized: extravasation type is most common and their pathogenesis is related to partial obstruction travasation type is most common and their pathogenesis is related to partial obstruction of the duct. Mucocele may occur in any location where accessary saivary gland tissue is found. However, most frequently, it occur on the lower lip. Clinically, it is painless, spherial, bluish, fluid-filled blister or vesicle. The lesions varies in size from a few millimeters to a centimeter. The preferred treatment is complete excision. If the mucocele is incompletely removed, it has a marked tendency to recur. This case report presents three cases. Two cases was developed on lower lip and the other was on dorsum of the tongue. All cases was extravasation type and treated by surgical excision of the lesion. There was no recurrence during follow up period about 5-12 months.

8년간(1992~1999) 산업안전보건연구원에 의뢰된 직업병 심의 사례 분석
강성규,김규상,김양호,최정근,안연순,진영우,최병순,양정선,김은아,채창호,최용휴,김대성,박정선,정호근 대한산업의학회 2000 대한직업환경의학회지 Vol.12 No.2
Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

In this pater, new design method for VLSI fault test are proposed by using built-in self test technique. The ordering algorithm for effective test pattern generation and the design method multi-input signature analysis for improving the fault detection capability are suggested. Also, a new multi-function BILBO(Built In Logic Block Observer) is sugested to reduce the hardware. By involbing the latch of sequential circuit into the BILBO, Built In Self Test can be executed effectively. The above proposed multifunctional BILBO was designed to operate both at a test pattern generator and a signature analyzer for reduction of the additional circuit and test time. Moreover, by using input and output line of multifunctional BILBO as a common, the external terminal are saved and the internal chip wiring can be done easily, and also the propagation delay of data signal is not ocurred. Through the implementation of test pattern generation and reordering and algorithm and multifunctional BILBO with C-language on the VAX 11/750(UNIX) computer, the efficienty of algorithm and the availability of designed method are verified.
