The neural network approach has been shown to be a general scheme for nonlinear dynamical system identification. Unfortunately the error surface of a Multilayer Neural Networks(MNN) that widely used is often highly complex. This is a disadvantage and potential traps may exist in the identification procedure. The objective of this paper is to identify a nonlinear dynamical systems based on Self-Organized Distributed Networks (SODN). The learning with the SODN is fast and precise. Such properties are caused from the local learning mechanism. Each local network learns only data in a subregion. This paper also discusses neural network as identifier of nonlinear dynamical systems. The structure of nonlinear system identification employs series-parallel model. The identification procedure is based on a discrete-time formulation. Through extensive simulation, SODN is shown to be effective for identification of nonlinear dynamical systems.

Author has studied and reported on taxonomy of Korean sedges, using gross morphology, anatomy and epidermal patterns of the leaf blades(1969, 1971, 1973, 1974). This paper is the 6th report of epidermal patterns of leaf blade on sedges and includes 5 genera, Eriophorum, Fuirena, Kobresia, Rhynchospora and Scirpus. The author proposed to find epidermal patterns of leaf blades as an important taxonomic characteristic of sedges classification. The result of this study, the elements of leaf epidermis, subsidal cells, silica body, cell wall of long cell, prickles, and arrangement of the elements are considered to be significant characteristics for the identification and classification of sedge.

During the period from 5 to 15 , August 1965 , the author had made collection of flies at Mt. Sol-ak, Kangwon-Do and a total of 2000 specimens was collected . A close examination of the specimens reveals that Sarcophaga sichotealini (Rohdendorf, 1938) and anthomyia illocata Walker , 1956 wer ehitherto unreported from Korea. The author wishes to express his deep appreciation to Dr, Rokuro Kano to whom he owes for the identification of the said two species.

The Author had tried to classify lip print patterne of 380 persons aged from 3 to 71 for detecting possibility of individual identification. The results were as follows: 1. The incidency of lip print patterne by means of the Tsuchihashi modifiation method was high in type I, type Ⅱ,typeⅢ,type I`, typeⅣ, typeⅤ, respectively. 2. Any of lip print had no same shape. 3. No same shape of lip print was found even family members. 4. The shapes of lip prints were unchangeable in the period of 5 months.

저자명 식별이란 다른 이름으로 표기된 한 명의 개인을 식별하는 것과 같은 이름을 가진 서로 다른 저자들을 각기 구별된 개인으로 분류하는 것으로, 저자의 연구 목록 및 연구 업적 평가, 특정 분야의 전문가를 검색하거나, 인용색인과 같은 학술 정보 서비스의 원활한 운영을 위해 반드시 해결해야 할 문제이다. 본 연구는 단순 머신러닝만을 사용한 실험 결과와 휴리스틱 방식으로 데이터 셋의 오류 수정 및 정규화 작업을 이후 머신러닝의 처리 과정에 룰 베이스 기반의 규칙을 부여한 저자명 식별 실험의 결과의 비교를 통하여, 인간의 개입이 머신러닝의 단점을 보완하고 저자명 식별 성능을 향상시킬 수 있는지 알아보았다. 그 결과 F-measure 0.1 이상 향상시킨 정규화 된 email기반의 룰 베이스 저자식별 결과로 정규화 과정과 휴리스틱 설정에 필요한 인간의 패턴인식과 추론능력이 머신러닝의 단점을 보완해줄 수 있음에 대한 가능성을 나타내었다.

As the improvement of digital technologies increases the use of images from various fields, the domain of image retrieval has evolved and become a growing topic of research in the Library and Information Science field. The purpose of this study is to identify the knowledge structure of the image retrieval domain by using the author co-citation analysis and author bibliographic coupling as analytical tools in order to understand the domain's past and present. The data set for this study is 245 articles with 8,031 cited articles in the field of image retrieval from 1998 to 2013, from the Web of Science citation database. According to the results of author co-citation analysis for the past of the image retrieval domain, our findings demonstrate that the intellectual structure of image retrieval in the LIS field consists of predominantly user-oriented approaches, but also includes some areas influenced by the CBIR area. More specifically, the user-oriented approach contains six specific areas which include image needs, information seeking, image needs and search behavior, image indexing and access, indexing of image collection, and web image search. On the other hand, for CBIR approaches, it contains feature-based image indexing, shape-based indexing, and IR & CBIR. The recent trends of image retrieval based on the results from author bibliographic coupling analysis show that the domain is expanding to emerging areas of medical images, multimedia, ontology- and tag-based indexing which thus reflects a new paradigm of information environment.

Authors observed a corpse which is died from "Charring", caused by air disaster, for the purpose of individual identification. This is an identifide case of the charred corpse due to the fire while landing of KAL 747 Jumbo(HL 7445) at Kimpo airport Nov.1980. It was referred to author in the state of carbonization by high degree of heat-as unknown body entirely. But teeth condition and treated condition were well preserved under mouth closing and by the comparative examination of antermortem dental records, dental radiographs, the individual identification was simply accomplished. Therefore, it brought repeatedly a recognition of the practical effectiveness of dental identification and importance or dental records.

Identification of blood group from dental hard tissue for the purpose of individual identification of a highly burned corpse would play a significant role in a practical legal medicine. The author conducted a study of blood group with teeth left stading at a high temperature by the method of elution test. The following results were obtained. 1. The blood identifcation from heated dental hard tissue proved to be possible. 2. In cases of heat-treated theeth at $100^{\circ}C$ for 120 minutes, at $150^{\circ}C$ for 120 minutes and at $200^{\circ}C$ for 45 minutes for A.B.O(H) blood group, the identification of blood group was possible. 3. In case of heat-treated teeth, thermostability of blood group was found to be $150^{\circ}C$. 4. The adequate surface area for the detection of blood group was 40-80 meshes.

The author analyzed acoustic parameters of ten Korean numbers produced by ten male students using Praat. Variations of f0, F1, F2 and F3 within and between speakers were examined by determining an average and standard deviation of the parameters of each number and by comparing the acoustic values with one another. Results showed that each subject produced the numbers within a certain range of variation across time. Thus, speaker identification can be more certain using dynamic information of the acoustic parameters within each vocalic segment. Also, percent difference of within-subjects' variation to that of between-subjects can be utilized to determine which sounds would be better stimuli for speaker identification. According to the criteria, the number '2' proved the best stimulus while the number '7' was the worst. Future studies will be necessary to explore robust methods of speaker identification under noisy conditions.

In the field Of individual identification in forensic Science, if the body is charred, it is sometimes impossible to identify the morphologic changes and charred tissue such as blood, muscle and bone can not be identified by forensic microbiologic method such as DNA typing. So the author used the characteristics of teeth which is relatively firm compare to other organs and stable to external environment such as heat and also possess cells needed for the DNA typing. The author conducted the experiment on teeth to detect DNA related to individual identification regarding to temperature in which other charredorgans can not be detected. The experiment was done on 64 extracted third molars consisted of unheated ones, and heated teeth to $100^{\circ}C$, $150^{\circ}C$, $200^{\circ}C$ for 45 min, 90 min, and 120 min respectively and to $250^{\circ}C$ for 45 min. DNA was extracted from each tooth and amplified fragment length polymorphism procedure(AMP-FLPs) using polymerase chain reaction(PCR) was applied and observed for the matching DNA in HumTH01 and HumCD4 locus and the followings Are the results : 1. It was able to detect matching DNA in HumTH01 and HumCD4 locus in every teeth which no heating has been done. 2. It was able to detect matching DNA in HumTH01 and HumCD4 locus in every teeth heated to $100^{\circ}C$ for 45, 90 and 120 min. 3. It was able to detect matching DNA in HumTH01 and HumCD4 locus in teeth heated to $l00^{\circ}C$, $200^{\circ}C$ for 45, 90, 120 min. 4. It was impossible to detect matching DNA in HumTH01 and HumCD4 locus in teeth heated to $250^{\circ}C$. So, it is possible to extract DNA from teeth that otherwise can not be extracted from other organs in the charred body and it can be concluded that teeth are highly reliable and applicatable as forensic odontology for individual identification.
