본 논문에서는 적은 비용으로 핵의학 영상을 상용 PACS에 전송하는 프로토콜을 개발하였다. 핵의학 DICOM gateway를 사용하여 자체 지역 네트워크로 연결되어 있는 PACS 네트워크와 핵의학과 네트워크를 연결하였다. 본원 핵의학 기기에서 사용하고 있는 Interfile 3.3을 PACS에서 사용하는 DICOM 3.0으로 변환하는 DICOM 변환 프로그램을 개발하였다. DICOM 변환 프로그램은 핵의학 영상을 DICOM으로 변환한 후 PACS DICOM gateway에 전송한다. PACS DICOM gateway는 핵의학과에서 전송된 영상 정보와 병원정보시스템 데이터베이스의 환자 정보와 일치 여부를 확인 후 PACS 데이터베이스에 저장한다. 전송방법으로 Interfile, 화면 캡쳐, 스캔 파일 형식, 등을 개발하였다. 핵의학 영상 전송은 성공적으로 이루어졌으며 Interfile로 전송하였을 경우 PACS에서 영상처리가 가능하였고 그래프와 주석 등의 정량적 정보는 화면 캡쳐 방법으로 쉽게 전송할 수 있었다. 필름은 스캐너로 스캔하여 화면 캡쳐와 동일한 방법으로 전송하였다. 핵의학 영상 전송 프로토콜 개발로 적은 비용으로 쉽게 핵의학 영상을 PACS에 전송할 수 있었다.

This paper is based on our comments and proposed amendments to the documents, Annex A, Phantom for determining Maximum Depth of Penetration, and Annex B, Local Dynamic Range Using Acoustical Test Objects 87/400/CDV. IEC 61391-2 Ed. 1.0 200X, prepared by IEC technical Committee 87; Ultrasonics. The documents are concerned with the influence of microstructure of reference target material on the ultrasonic backscattering. Previous works on the attenuation due to backreflection and backscattering of reference target materials are reviewed. The drawback to the use of ungraded stainless steel and metallic materials without microstructural data such as, crystal structure, basic acoustic data of sound velocity and attenuation, grain size, roughness and elastic constants has been discussed. The analysis suggested that the insightful conclusion can be made by differentiating the influence arising from target size and microstructure on the backscattering measurements. The microstructural parameters are associated with physical, geometrical, acoustical and mechanical origins of variation with frequency. Further clarification of such a diverse source mechanisms for ultrasonic backscattering would make the target material and its application for medical diagnosis and therapy simpler and more reliable.

User review sites are spaces where users can freely post and share their opinions, which are trusted by many people and directly influence sales. In addition, they overcome the limitations arising from existing requirements collection and are able to gather the needs of large numbers of different people at a low cost. Therefore, such sites are attracting attention as new spaces for understanding user needs. In a previous study, a user review analysis was attempted using 5W and 1H, and we inferred that a sentence containing "when" has special information based on the user experience. In addition, the requirements of the derivative activities in a user review can identify more user needs than the general requirements of derivative activities. In this paper, we propose a systematic method of deriving "when" sentences contain meaningful information from user reviews and converting them into use cases, which is one of the requirements of a specification method. This method converts unstructured data into structured data such that it can be included as the user requirements during software development from user comments expressed in natural language. This method will reduce project failures and increase the likelihood of success by enabling an efficient collection and analysis of user needs from valuable user reviews.

In this paper, under some new appropriate conditions imposed on the parameter and mappings involved in the resolvent operator associated with a P-accretive mapping, its Lipschitz continuity is proved and an estimate of its Lipschitz constant is computed. This paper is also concerned with the construction of a new iterative algorithm using the resolvent operator technique and Nadler's technique for solving a new system of generalized multi-valued resolvent equations in a Banach space setting. The convergence analysis of the sequences generated by our proposed iterative algorithm under some appropriate conditions is studied. The final section deals with the investigation and analysis of the notion of H(·, ·)-co-accretive mapping which has been recently introduced and studied in the literature. We verify that under the conditions considered in the literature, every H(·, ·)-co-accretive mapping is actually P-accretive and is not a new one. In the meanwhile, some important comments on H(·, ·)-co-accretive mappings and the results related to them appeared in the literature are pointed out.

After translating the contents of "Treatise on Bundon Disease in Chapter 8 of the Essence of the Synopsis of the Golden Chamber" and it was compared with the contents of "The Lecture of Synopsis of Prescriptions of the Golden Chamber" and speculated to review the characteristics of the comments of Ui(尤怡) and the following conclusions were made. As the causes of bundon(奔豚) disease, which means gas rushing like a running piggy from the lower abdomen to the throat, they could be categorized into the cases belongs to miscellaneous diseases (雜病) and into the cases of suffering from cold diseases(傷寒). If it was diagnosed as miscellaneous disease, terror and fear(驚恐) could be regarded as its cause and if it was diagnosed as cold disease, insufficiency of heart Gi(心氣) due to the excessive sweating and the invasion of exterior coldness could be regarded as its cause. As the pathogenesis of this disease, the pathogenic factors of liver and kidney could be found. Since the liver and Soyang meridian(少陽經) are subjected to the exterior and interior relation in case of the pathogenic factor of liver, alternate attacks of chills and fever(寒熱往來) could be characteristic for the disease. If this disease was caused by the pathogenic factor of kidney, there are two cases. One is the palpitation under the umbilicus(欲作奔豚: 臍下動悸) developed by the lack of heart Gi(心氣) and the other is gas rushing like a running piggy from the lower abdomen to the throat which could be developed by the exterior cold disease which invade into the interior and reach into the kidney when the heart Gi(心氣) was insufficient. In its treatment, bundon disease caused by the pathogenic factor of liver could be treated with Bundontang(奔豚湯), and the understanding of Ui(尤怡) on Pinellia ternata Breitenbach(半夏) having the effect of perspiration in the prescription is quite unique concept. In case of bundon disease caused by the pathogenic factor of kidney, treatment is focused to treat exterior coldness by applying moxibustion(灸) and Gyejigagyetang(桂技加桂湯), and in case of the palpitation under the umbilicus(欲作奔豚: 臍下動悸), its pathogenic factor of kidney is controlled with Cinnamomum louerii Nees(桂技), Polia cocos Walf and the spleen Gi(脾氣) is cared by using Glycyrrhiza uralensis Fischer et. De Candolle(甘草) and Zizyphus jujuba Mill(大棗). Especially, Ui(尤怡) emphasized Cinnamomum louerii Nees(桂技) as the medication to treat the pathogenic factor of kidney.

Objectives : To develop and validate a survey form for adverse events(AEs) associated with acupuncture and moxibustion treatment. Methods : The 1st version of a survey form consisting of 9 categories was developed and modified based on the analysis of questionnaires from previous studies on AEs. To evaluate content validity of the 1st version, a Delphi survey where experts in acupuncture and moxibustion, and research methodology were invited, was conducted alongside a separate content validity questionnaire. The content validity indices for each item and total scale were calculated as the proportion of the number of experts judging each item or scale valid to the number of total experts. Results : After the Delphi round 1, the content validity of 2 items and total scale was rated as inadequate. The 1st version was modified accordingly, and the 2nd version of the survey form was developed. The content validity of the 2nd version was assessed in the Delphi round 2 and the final version was completed after incorporating the expert comments. The final version consists of 13 questions regarding practitioner/patient information, condition/disease, intervention, treated body parts, safety issue and AE occurrence related with practitioner's behavior or instruments, AEs associated with treatment and emergency actions taken if necessary, time to AE occurrence, outcomes, serious AEs or death, and time to AE disappearance. Conclusions : This newly developed and validated survey form will serve to collect AEs associated with acupuncture and moxibustion treatments in Korea and contribute to establishing the evidence on safety of Korean acupuncture treatment.

Backgrounds & Methods : Asthma is considered to be chronic inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia. Recently, there has been many researches about asthma. IBS(Irritable Bowel Syndrome), PUD(peptic Ulcer disease) and GERD(gastroesophageal reflux disease) are the most common diseases of the gastrointestinal tract. Recent studies suggest that IBS, PUD and GERD are associated with bronchial hyper-responsiveness and bronchial asthma might be more prevalent in IBS and GERD patients than in control subjects. In addition, there are many comments about the interrelationship between the gastrointestinal problem and asthma in the oriental medical books. Actually, many oriental medical doctors don$^{\circ}$Øt consider the gastrointestinal condition when they deal with the asthmatic patients these days. So, we assessed the prevalence of gastrointestinal symptoms and histories in a cohort of patients with asthmatic symptoms. We evaluated 128 outpatients with asthmatic symptoms(60 males and 68 females, aged 13-75). All subjects enrolled completed the GSRS(Gastrointestinal Symptom Rating Scale). GSRS is an interview based rating scale consisting of 15 items for assessment of gastrointestinal symptoms in IBS and PUD developed by Jan Svedlund. Results : The limit of total score of GSRS in asthmatic patients is zero to 30. The number of patients with no GI symptoms is 66(51.5%). The number of patients with GSRS>5 is 62(48.4%), GSRS>10 is 24(18.8%), GSRS>15 is 8(6.25%). The number of patients with history of gastritis is 54(42.2%), gastric ulcer is 13(10.2%), gastroptosis is 8(6.25%), IBS is 6(4.68%), others is 6(4.68%). Conclusions : This study suggests that patients with bronchial asthma have an significant prevalence of gastrointestinal symptoms. Additional studies are needed to find the mechanism of the association between gastrointestinal symptoms and asthma.
