Ninerty one of Trichoderma spp. were isolated from ginseng growing bed, dead trees and muchroom in Korea from March 1978 to June 1979. Six species were identified as T. hamatum(13 strains), T, roningii(17 strains), T. aureoviride(4 strains), but other six strains(strain No. 111, 125, 127, 130, and 503) unidentified by Rifai's key. The reason which is not identified is as following. According to Rifai's key, phialid, phialospore and colony's colour of four strains (strain No. 125, 126, 127 and 130) are like T. longibrachiatum, but they are different from Rifai's method, because sterile-hypha often appears. the fature of standard strain ATCC no. 13631 T. longibrachiatum is like ster9ile-hypha that is used strains in this experiment. The morphology of strain No.503 is the same as T. hamatum except phialospore. Gnerally, T. hamatum's phialospore is subcylindrical, but strain No. 503 is regular ovoid. Therefore, strain No.503 cannot be identified by Rifai's key. The property, strain No.111's phialid is very irregular $(5{\sim}20{\times}2{\sim}2.5{\mu})$) and its phialospore $(4.0{\sim}6.0{\times}3.0{\sim}4.0{\mu})$) is subcylindrical, is uncomfortable to Rifai's method. The standard strains used in this experiment are 7 kinds of Trichoderma spp. received from ATCC.

Purpose: The purpose of the study was to identify functional structure and patterns of dialogue sequence in conversations between elderly patients with dementia and nurses in a long-term care facility. Methods: Conversation analysis was used to analyze the data which were collected using video-camera to capture non-verbal as well as verbal behaviors. Data collection was done during February 2005. Results: Introduction, assessment, intervention, and closing phases were identified as functional structure. Essential parts of the conversation were the assessment and intervention phases. In the assessment phase three sequential patterns of nurse-initiated dialogue and four sequential patterns of patient-initiated dialogue were identified. Also four sequential patterns were identified in nurse-initiated and three in patient-initiated dialogues in the intervention phase. In general, "ask question", "advise", and "directive" were the most frequently used utterance by nurses in nurse-initiated dialogue, indicating nurses' domination of the conversation. At the same time, "ask back", "refute", "escape", or "false promise" were used often by nurses to discourage patients from talking when patients were raising questions or demanding. Conclusion: It is important for nurses to encourage patient-initiated dialogue to counterbalance nurse-dominated conversation which results from imbalance between nurses and patients in terms of knowledge and task in healthcare institutions for elders.

The recent research on proper orthogonal decomposition (POD) has revealed the linkage between proper orthogonal modes and linear normal modes. This paper presents an investigation into the modal identifiability of an instrumented cable-stayed bridge using an adapted POD technique with a band-pass filtering scheme. The band-pass POD method is applied to the datasets available for this benchmark study, aiming to identify the vibration modes of the bridge and find out the so-called deficient modes which are unidentifiable under normal excitation conditions. It turns out that the second mode of the bridge cannot be stably identified under weak wind conditions and is therefore regarded as a deficient mode. To judge if the deficient mode is due to its low contribution to the structural response under weak wind conditions, modal coordinates are derived for different modes by the band-pass POD technique and an energy participation factor is defined to evaluate the energy participation of each vibration mode under different wind excitation conditions. From the non-blind datasets, it is found that the vibration modes can be reliably identified only when the energy participation factor exceeds a certain threshold value. With the identified threshold value, modal identifiability in use of the blind datasets from the same structure is examined.

In this paper, a new protocol-based approach was proposed for development of a ubiquitous vision system. It is possible to apply the approach by regarding the ubiquitous vision system as a multiagent system. Thus, each vision sensor can be regarded as an agent (vision agent). Each vision agent independently performs exact segmentation for a target by color and motion information, visual tracking for multiple targets in real-time, and location estimation by a simple perspective transform. Matching problem for the identity of a target during handover between vision agents is solved by the Identified Contract Net (ICN) protocol implemented for the protocol-based approach. The protocol-based approach by the ICN protocol is independent of the number of vision agents and moreover the approach doesn't need calibration and overlapped region between vision agents. Therefore, the ICN protocol raises speed, scalability, and modularity of the system. The protocol-based approach was successfully applied for our ubiquitous vision system and operated well through several experiments.

This study was conducted to identify native ectomycorrhizal (ECM) fungi colonizing Pinus densiflora for revegetation of abandoned coal mines in Korea. Seedlings of P. densiflora growing on coal mining spoils of a study site in Samcheok were collected. ECM roots were observed under stereomicroscope and their DNA were extracted from each root tip for a seedling for molecular identification. A PCR primer pair specific to fungi, ITS1F and ITS4, was used to amplify fungal DNA. Restriction enzymes, Alul and Hinfl were used for restriction fragment length polymorphism (RFLP). Combined with RFLP profiles and sequence analysis, total twenty one taxa were identified from the ECM root tips. Basidiomycetous fungi including Thelephoraceae, Pezizales, Laccaria, Pisolithus and Ascomycetous fungi including ericoid mycorrhizal fungi were identified from this study. Results showed that the most frequently found in the study sites was a species in Thelephoraceae. A possible use of ECM fungi identified in this study for the revegetation of abandoned coal mines with P. densiflora was discussed.

This study was carried out to investigate the flora of Is. Gageo (Jeollanam-do). The vascular plants were collected 13 times (from June 2008 to September 2011), and 465 taxa in total were identified, including 112 families, 301 genera, 402 species, 3 subspecies, 49 varieties, 9 forms and 2 hybrids. 171 taxa were first records for the region. Among them were seven taxa of Korean endemic plants and the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as three taxa. There were 54 taxa of the flora with the levels III, IV, V in the floristic indicator plants which was designated by Ministry of Environment. The naturalized plants were identified as 29 taxa, and their naturalization ratio and urban index were found to be 6.2% and 9.0% respectively. There existed many kinds of plants resources having conservational value like $Loxogramme$ $salicifolia$, $Sarcandra$ $glabra$, $Osmanthus$ $insularis$, $Saussurea$ $polylepis$, $Carex$ $ligulata$ var. $austrokoreensis$, $Hosta$ $jonesii$, $Cyrtosia$ $septentrionalis$, etc., in this area. As therefore clear that appropriate plans to conserve the natural habitat of Is. Gageo must be made immediately.

The rectnt studies on the learning of the scientific concepts have suggested that most students have misconceptions related to the contents to be learned and that those misconceptions exert their influences on the subsequent learning of the content Those facts necessitate the identification of the misconceptions before the instructions and the preparation of the instructional materials based on those misconceptions identified. Several studies also revealed that such biological areas as cell division, reproduction and fertilization were ranked among the most difficult areas for high school students to learn. Therefore, this study had its triple objectives as follows: (1) Identification of misconceptions in such areas as cell division, reproduction and fertilization. (2) Investigation of the current high school biology textbook I's as the sources of those misconceptions. (3) Development of teaching materials based on the misconceptions identified and the problems in the textbooks analyzed. This study identified several misconceptions held by high school students of biological concepts related to the conceptual areas of life-continuity, and found the problems in learning of the high school biology textbooks. Based on the misconceptions and the problems, a teaching/learning model and its content material were developed at the final course of this study.

This study examined the consumption of licensed sports fashion products by sports fans in order to provide useful information to apparel companies that are interested in sports sponsorship marketing. Grounded theory approach was adopted to explore consumers' attitude toward the sponsoring companies, and motives of buying licensed fashion products. In-depth interviews were conducted with female fans of professional baseball clubs. The main phenomena of interest was consumer purchase of licensed fashion product, with the emphasis on cultural consumption as a causal condition. Providing support for victory, vicarious consumption, social identification, and needs to differentiate were identified as strategies related to licensed product purchase. Economic situations and limitations to purchase are identified as the mediating conditions. The study identified the effects of the consumption on the fan as well as the sponsoring companies as consequences of the phenomena. Sports marketing strategies were suggested for apparel companies based on the analysis of the consumption rituals for licensed fashion goods.

Two leptocephali [total length (TL) 68.2-80.5 mm] from the family Ophichthidae, collected from the waters south of Jeju Island, Korea, were identified using morphology. The two ophichthid leptocephali were identified as belonging to the genus Ophichthus based on morphological characters: 131-132 myomeres; nine gut swellings; dorsal fin origin above the middle of the body; five postanal pigments present from the anus to the caudal margin. Ultimately, both leptocephali were identified as Ophichthus asakusae, as the total number of myomeres was consistent with those of adult O. asakusae. Here, we first describe the morphological characteristics of the O. asakusae leptocephalus, and suggest diagnostic characters for leptocephali belonging to the genus Ophichthus.

CCTV image processing techniques have been developed for safety management in manufacturing sites. However, CCTV growth has become a social problem for video surveillance with regard to privacy. This study aims to manage the safety system efficiently and protect privacy simultaneously. In this study, the CCTV monitoring system is composed of five steps (accident monitoring, detection, notification, management, restoration). De-identified image is observed when we are in a normal situation. De-identified image changes to identified image when it detects an accident. As soon as it detects an accident, the accident information is sent to the safety administrator. Then the administrator could conduct safety measures. Afterward, accumulated accident data could be used for statistical data that could be utilized as analyzing expecting accident.
