Diabetic polyneuropathy (DPN) is the most frequently encountered form of neuropathy in diabetic patients, and it either relentlessly progresses or remains relatively stable for many years, not showing any trend towards improvement. From this point of view, early detection of DPN is very important to prevent the irreversible change of the peripheral nerve from diabetic insults. Although a number of clinical symptoms and/or deficit scales have been developed for clinical or research purposes, nerve conduction study (NCS) has been known one of the most objective and sensitive tools to detect peripheral nerve dysfunctions in diabetic patients. NCS, however, also have several shortcomings. The next two consecutive articles will focus on debates about diagnostic usefulness of NCS and on recent updates of other diagnostic tests including quantitative sensory testings and skin biopsy in the field of diabetic polyneuropathy.

In this study, we conducted preliminary survey, diagnostic test and in-depth interview in order to study Korean pre-service chemistry teachers' understanding on entropy and investigate how Korean pre-service chemistry teachers deal with the natural phenomenon which is related to entropy conceptions. Firstly, as a result of the preliminary survey, it was found that pre-service chemistry teachers strongly recognized entropy as the degree of disorder. Secondly, the diagnostic test showed pre-service chemistry teachers were mostly confused about whether the entropy of the universe increases during a spontaneous change, and they had a tendency to interpret the natural phenomenon related to entropy change as the change of disorder. Finally, during in-depth interview, after we explained entropy change in all diagnostic test questions with the concept of microstate, pre-service chemistry teachers revealed a better understanding about entropy. Through this research, pre-service chemistry teachers had an opportunity to reflect on their deficiencies of entropy conceptions, which will ultimately help students to approach the concept of entropy more correctly.

The aim of this study is to propose the desirable plan of the diagnostic radiology department in general hospital. The main contents and results of this study are as follows. 1. By investigating and analyzing the activities and circulation of the patients and staffs in diagnostic radiology department, the activity model of the department was extracted. 2. The types of operating system of the department were extracted and activity model by the operating systems were made. 3. The types of the plan of the department were classified into three types, such as confusing-corridor type, separated-corridor type and contract type. 4. After dividing them into eight types in detail, the merits and demerits of each type were analyzed. 5. Among those types contact types were evaluated best in comparison with the other types in terms of efficiency of staff's work, access of patients to staffs and reduction of staffs movement.

This paper was performed research for the total filtration in the useful beam of 45 diagnostic x-ray equipments using in Korea. We obtained the following results: 1. A good ability of total filtration was showed in higher than lower maximum permissible rating equipments. 2. In 53 percentage of 45 diagnostic x-ray equipments, the total filtration in the useful x-ray beam was not less than the values given in the Korean industrial standard. This results suggested to user to need the more ability management of diagnostic x-ray equipments using now.

With the rotating machinery getting more accurate and diversified, the necessity fur an appropriate diagnosis technique and maintenance system has been greatly recognized. However, until now, the operator has executed a monitoring of the machine by the senses or simple the change of RMS (root mean Square) value. So, the diagnostic expert system using the fuzzy inference which the operator can judge easily and expertly a condition of the machine is developed through this study. In this paper, the hardware and software of the diagnostic expert system was composed and the identification of the diagnostic performance of the developed system for 5 fault phenomena was carried out.

With respect to the effectiveness of types of knowledge on human diagnostic performance, the results of several experiments claimed that training with diagnostic rules (procedural knowledge) is more effective than training that provides theoretical knowledge (principle knowledge). However, we usually have the idea that understanding the principles of system dynamics is necessary for diagnosis in some situations. In this study, we pointed out some problems in the previous experiments that force to reinterpret their experimental conclusions. Accordingly, we conducted an experiment to reinvestigate the value of theoretical knowledge in two problem situations. A simulator system, which is named DLD, that is to diagnose an electronic device was created for this purpose. It is a context-free digital logic circuit which includes forty-one gates of three basic types. Our experiment investigated the marginal effects of theoretical knowledge over common diagnostic rules. The experimental results showed that the effectiveness of the instruction in theoretical knowledge is dependent on the complexity of diagnostic situations. This adds up an experimental evidence against the presumed ineffectiveness of theoretical knowledge and forward reasoning in fault diagnosis. Furthermore, the result suggests the source of the use of theoretical knowledge.

Objective : The purpose of this paper is to report the effect of Danggwihweyeokgaohsuyu-saenggang-tang(DHGOST) on primary dysmenorrhea from the disease pattern identification diagnostic system based on Shanghanlun provisions. Methods : According to a disease pattern identification diagnostic system based on Shanghanlun provisions, the patient was diagnosed with 'Reverting Yin Disease'. She took DHGOST for 75 days. This paper evaluated the results of treatment by Measure of Menstrual Pain(MMP) and Menstrual Symptom Severity List(MMSL) Results : The MMP score was declined from 8.3 to 3.5. And the MMSL score was declined from 46 to 38. Conclusions : This case study suggests that DHGOST has effectiveness on primary dysmenorrhea who is diagnosed with 'Reverting Yin Disease'.

Computerization for the work of diagnostic radiology department is needed to manage the department efficiently, to deal with the information increasing gradually, and to provide qualified care for patients. There is few computerized management system for diagnostic radiology department in our country. Foreign systems were developed commercially and academically, but almost failed to meet the needs of demands. So in this paper, to help the exploitation of soft ware suitable for the information system of diagnostic radiology department of our country; 1) foreign systems were introduced. 2) Data flow of diagnositc radiology department was analysised by SSA method. 3) Composition of computer system centered on the functions of terminals was presented.
