The aim of the present recent study was to compare the protein patterns in the vaginal mucus of Hanwoo cattles during spontaneous and CIDR induced-estrus. Ten cattles, who had been observed in estrus, received no treatment and served as the group of cattles with normal spontaneous estrus. Thirteen cattles in the CIDR received an CIDR insert on day 14 were removed and cattles were injected GnRH on day 15. Vaginal mucus samples were collected from all cattles at the same time the single AI in cattles with spontaneous estrus and the AI in cattles with induced estrus. Spontaneous and CIDR-induced estrus vaginal mucus samples were analyzed on two different array surfaces: cation-exchange (CM10), anion-exchange (Q10). In addition, using the NaCl solution by which the proteins combined after washing are 0.5, 1 and 2 M, it was fractionated and a protein was collected successively. The results are summarized as follows: 1) Ionic surfaces chemistries (Q10 and CM10) gave the best results in terms of detectable protein peaks, with more than 100 protein peaks in the two fractions and under each condition. 2) Protein mass spectrometer using 11 different proteins in protein identification of 7 were able to determine the protein. List of identified proteins as follows; Ribosome-binding protein 1, GRIP 1-associated protein 1, Katanin p60 ATPase-containing subunit A-like 1, Protein FAM44A, DUF729 domain-containing protein 1, Prolactin precursor, Dihydrofolate erductase. Conclusively, on the basis of this study, protein expression in the vaginal mucus could be used as an indicator for time of estrus manifestation in order to increase conception rates by applying AI at an optional time.

최근 녹색교통수단으로서 자전거의 이용자수는 급격하게 증가하고 있으나 차대 자전거사고 감소와 자전거 이용자의 안전성 향상에 대한 노력은 미비한 설정이다. 따라서 본 연구에서는 최적의 교차로 설계지침 제공 및 자전거 사고유형에 영향을 미치는 요인들을 면밀히 분석하여 교차로에서의 자전거사고 안전성 향상에 그 목적이 있다. 이를 위해 본 연구에서는 2005년도 인천광역시 사지교차로에서 발생한 56건의 자전거사고 자료에 대한 분석과 사고발생 교차로에 대한 현장조사를 실시하였으며, 다항로짓모형을 이용하여 3가지 경우에 대한 자전거 사고유형 분석모형을 개발하였다. 모형분석결과, 사망사고 유무, 부도로 교통섬 유무, 도로위계, 사고당시 날씨, 주도로 버스정류장 유무, 주도로 차로폭, 인적유발요인이 자전거 사고 유형에 중요한 변수로 나타났다.

The purpose of this article is to suggest John Wesley’s attempt to church renewal in the 18th century England through exploring his ecclesiology. This article deals with patterns of church renewal as it uses Wesley’s ecclesiology and Howard Snyder’s mediated model of church renewal, and attempts to rediscover of the essence of the church, and finds out clues of renewal and transformation of the Korean church along with the lessons given to the Korean church today. John Wesley constructed a very creative ecclesiology which was integrated various insights given by innovative renewal movements in the early church and the church history along with the understanding of the traditional church. Therefore John Wesley's understanding of the church can be understood through his renewal movement. Also his ecclesiology emphasizes the community for renewal of the church. In fact, Wesley's original intention was to form a organic community, that is, “ecclesiola in ecclesia.” In order to achieve his church renewal ministry Wesley suggested a integrated(holistic) renewal model that would keep the balance between institution and movement. Some characteristics of a renewed church is a living organism not just a institution or organization. The renewed church is charismatic community. Church renewal movement can not be separable with the kingdom of God. In this sense, Howard A. Snyder suggests five dimensions of John Wesley’s church renewal movement. First, it is individual renewal as it takes place in believer's personal repentance and conversion. It is spiritual renewal. But it is not just spiritual but communal. Unless there is no true community, individual renewal cannot be taken place. Second, communal renewal means a shared faith in a community as it happened when the church experiences God's transforming work. Third, conceptual renewal(or theological renewal) means a paradigm shift in theology. In this aspect, every great renewal movements are closely related to conceptual renewal. Fourth, structural renewal is to change forms and structures of which the church uses. Thus, the church must be changed in cultural contexts. Institutionalized and rigid structures of the church can often hinder the work of the Holy Spirit. Even though structural change is not the starting point of renewal, it can keep the renewal movement continue. Fifth, missional renewal of the church is about passion of proclaiming the gospel as the essential call of the church. Missional renewal can be accomplished when the church rediscover the essence of mission. This is not for the church itself but for the kingdom of God. The church that is internally renewed must have missional renewal. In this sense, the Korean church can learn from John Wesley’s renewal movement which attempted to renew the church by forming the authentic community connected with the kingdom of God.

본 연구의 목적은 인간의 간섭 및 영향에 따른 도시지역에서의 식물종의 분포패턴 및 특성을 분석하는데 있다. 전주시에서 자생적으로 이입된 모든 유관속 식물종에 대한 포괄적 자료습득을 위하여 각 1헥타 크기의 106개 표본 조사구가 분석되었다. 이러한 표본조사구는 전주시의 전형적인 토지이용유형을 대표하고 도심지역으로부터 다양한 이격거리를 갖도록 선정되었다. 종풍부성, 생활형의 패턴 그리고 외래종의 비율이 표본조사구의 헤메로비 정도와의 관계에 대해서 분석되었다. 식물종의 수는 적당히 영향을 받는 부지에서 가장 높게 나타남을 알 수 있었다. 이는 적당한 교란은 종풍부성 증가를 유도한다는 중간 교란 가설에 상응하는 결과이다. 인간의 영향을 가장 많이 받는 부지의 식물상은 일년생 식물과 외래종의 비율이 가장 높은 특징을 보였다. 그리고 일부 식물종들은 토지이용유형과 도시구역에 상응하는 유사한 분포를 갖는 세 가지 그룹인 도시지역 기피종(땅비싸리, 졸참나무, 개옻나무 등), 도시지역 및 외곽지역에 널리 분포하는 종(닭의장풀, 개망초, 박주가리 등)과 도시지역 선호종(애기땅빈대, 개쑥갓, 서양민들레 등)으로 구분되었다.

Determining age distributions of insect is required for many basic ecological studies. Most of insect developmental studies, the head capsule width and other developmental traits have been widely used to distinguish the instars. Unlike to other insect species, collembolan continues to molt after they reach sexual maturity. So these traits sometimes make it difficult to conduct developmental studies. Model animal used in this study was Paranura rosea a native collembolan speciese. To determine the age groups of P. rosea, we periodically (1week) made digital images of P. rosea (over 100 different images) under the magnifier (DIMIS-M) for consecutive 20 week. And then the head capsule width and the surface area of P. rosea were analyzed using a image software (ImageJ). In this test the head capsule widths and surface area were set as developmental parameters. Both two developmental parameters showed time-dependent increase patterns. And they gave good agreements between predicted developmental parameters and observed parameters (r2=0.83 and 0.71). Based on the reproducibility of juveniles and statistical mean separation tests (tukey's test), both two developmental parameters could be divided into 3 age groups. The information given this study will be used as a basis for understanding the population dynamics and other ecological research.

As an effective generalist predator of aphids and other hemipteran pests, Harmonia axyridis has been a successful biological control agent. Interestingly, it was known that there were varied in color patterns on H. axyridis elytra. In fact, Seo & Youn (2007) reported that H. axyridis had five color patterns, for example, succinea 1, 2, conspicua, spectabilis, and axyridis. But there are uncertain that H. axyridis elytra colour patterns are regulated by genetic polymorphism. So we tried to what is the reason that color patterns are greatly variable. To identify DNA markers linked to a elytra polymorphism, amplified fragment length polymorphism (AFLP) analysis was performed on DNA samples from four female succinea, conspicua, spectabilis and Coccinella septempunctata which is another species in Coccinellidae. AFLP analysis with the restriction endonuclease combination EcoRⅠ and MseⅠwas performed. Using 12 AFLP primer pairs, nine AFLP fragments which is specific between succinea, conspicua, spectabilis was identified. These nine AFLP fragments were isolated, cloned and sequenced. Subsequent UPGMA cluster analysis revealed three major group of H. axyridis populations. These genetic tree showed that H. axyridis elytra colour diversity was affected by genetic polymorphism. For more genetically understanding elytra colour genes, different primer combinations may be need to be generate enough polymorphic markers. These genetic analyses may be facilitate the understanding of molecular mechanism behind wing colour pattern formation.

The genus Linaeidea Motschulsky, 1860, contains six species, and is distributed in China, Japan, USSR, Europe, with only two species known in Korea (Gressitt and Kimoto, 1963; Seeno and Wilcox, 1982; Kimoto and Takizawa, 1994; Lee and An, 2001). Morphological notes of the immature stages and life history of Japanese L. aenea (Linne, 1758) were well studied by Kimoto (1962)and Kimoto and Takizawa (1994). Very little is known about the immature stages of this genus from Korea: only the larva of L. aenea have been briefly described and illustrated by Lee (1996). According to Hennig (1938), this genus is separable from the genus Chrysomela, in having sternal tubercles which are disappeared in the last instar larvae. However, the L. adamsi was not applied in the diagnosis character of this genus. The purpose of this results are to provide a key, detailed description, illustration and tubercles patterns of all known Korean species of genus Linaeidea as the basic data for the phylogenetic study the subfamily Chrysomelinae.

본 연구는 사육환경 조건에서 참수리(Haliaeetus pelagicus)의 연령에 따른 꼬리깃의 변화 과정을 조사하기 위해서 2000년 11월부터 2006년 7월까지 약 6년간 경성대학교 조류연구소에서 조사한 것이다. 꼬리깃의 깃갈이 시기는 보통 7월부터 시작해 익년 4월까지 진행되었으며, 1회의 깃갈이에 모든 깃이 교체되었다. 보통 12월 이전에 2/3 정도가 교체되었으며, 나머지는 익년 4월까지 모두 교체되었는데, 겨울동안에도 깃갈이가 지속되었다. 꼬리깃의 총 개수는 14개로써 깃갈이는 번갈아가면서 단계적으로 이루어졌고 암컷은 4단계, 수컷은 3단계로 진행되었는데 각 단계마다 좌.우측 깃이 대칭적으로 진행되는 것이 특징이었고 한 단계의 성장이 거의 끝날 때 다음단계가 시작되었다. 유조 꼬리깃의 빛깔은 흰색 바탕에 검은색 얼룩이 산재해 있고 깃의 끝부분에는 불규칙적인 검은색 띠가 있었는데 1-3세대깃(1-3차 여름깃)까지는 빛깔의 차이가 극히 적어 꼬리깃으로만 연령을 파악하기는 어려웠다. 또한 개체별로 나타나는 검은색 얼룩무늬의 양도 다르다는 것을 고려했다. 4세대 깃(4차 여름깃)은 3세대 깃에 비해서 큰 차이를 보이며 흰색깃에 약간의 검은색 얼룩만 존재하였다. 4차 깃갈이가 끝난 5세대 깃(5차 여름깃)은 순 백색의 완전한 성조 꼬리깃의 빛깔을 갖추었다. 야외에서 참수리를 관찰하였을 때 3세대 깃(3차 여름깃)까지는 연령을 판단하는데 신중한 검토가 필요하며 꼬리깃 외에 다른 부위의 깃 변화도 함께 관찰해야 할 것으로 생각한다.

This study examined the actual consumption status and consumer preference for juk via questionnaire survey to provide useful basic data for the development of diversified commercial juk products. The survey data were collected from a target number of 450 participants living in the Seoul area. The subjects represented different age groups (over 20 years old) and both genders. Through a market survey based on five different retailers, which included juk-specialty stores, supermarkets, and local shopping marts, 17 kinds of commercial juk were chosen for the survey. Consumption frequency and purchasing factors were examined, along with preferences toward commercial juk products and areas for quality improvement. The results revealed that 54.0% of the respondents consumed commercial juk, and male consumers exceeded female consumers in number. It was also shown that those in their 20°Øs consumed commercial juk products the least as compared to other age groups. With regard to commercial juk preferences by type of production mode, females especially preferred specialty store juk while males preferred retort juk sold in supermarkets or local shopping marts. In addition, 85.7% of the total respondents indicated that commercial juk should be further improved in quality, and they specifically noted possible improvements in the areas of ‘choice diversification’ and ‘healthy juk’ products. Therefore, one can conclude that by making such improvements, increase in consumption and further diversification of commercial juk products could be realized.

직물의 결점은 원단손실을 가중시키기 때문에, 검단공정에서 결점부위를 제거한다. 실제공장에서 이뤄지는 검단공정은 육안판정방식과 전자동 방식 중 하나를 채택하는데, 두 방식 나름대로 장단점이 있다. 본 연구에서는 육안판정과 전자동 방식의 장점만을 모아 검출은 사람이 하지만, 결점위치 정보 제공 및 결점정보 기록을 컴퓨터가 하도록 반자동 검단기를 개발하였다. 본 연구에서 개발한 레이저 그리드는 결점의 위치를 검단자가 쉽게 파악하도록 돕는 역할을 하며, 야드미터는 자동으로 결점의 위치를 측정하는 역할을 한다. 컴퓨터는 야드미터로 측정된 직물의 길이와 사람이 검출한 결점의 위치정보를 받아들여 저장하고 직물의 결점정보를 한눈에 보여주는 역할을 한다. 실제 사용되는 직물을 대상으로 특정 패턴으로 재단했을 때의 손실률을 계산하여 개발된 시스템의 성능을 객관적으로 평가하였다.

Three benzimidazole pesticides commonly used in korean lettuce were subjected to a field residue trial to ensure safety of terminal residue in the harvest. The residual patterns of three benzimidazole pesticides, which were carbendazim, benomyl and thiophanate-methyl were examined after applying with the recommended dose in two types of korean lettuce (Chima and Chuckmeon) and their DT50 were calculated. In Chima lettuce, biological half-lives of carbendazim, benomyl and thiophanate-methyl were 2.56, 1.37 and 2.54 days, respectively and their required time under MRL(5.0 mg/kg as carbendazim) were 4.5, 2.2 and 1.0days. In Chuckmeon lettuce, biological half-lives of them were 3.41, 1.70 and 4.20 days, respectively and their required time under MRL were 5.4, 1.9 and 0.5days.

Benthic macroinvertebrates were collected with a Surber sampler in streams across different levels of pollution in Korea. Abundance data in different species were analyzed according to the models used in species abundance distribution (SAD), covering geometric series, log series and log normal model. Different patterns in SADs were observed according to the states pertaining to the sample sites. While the log normal patterns were broadly applied to the collected samples, the other models (e.g., geometric series) were selectively observed. The slopes of rank abundance also accordingly reflected the degree of pollution. Application of the theoretical models was additionally discussed in revealing the states of communities. Efficiency of SADs was proposed in community monitoring in response to stressful conditions in aquatic ecosystems.

The surface of most coccinellids (particularly the elytra) has characteristic colour patterns, which show great variability within many species. Individuals of a species of ladybird often differ from one another in colour and pattern. In case of Harmonia axyridis, environmental factors, such as temperature or food, can probably influence colour and pattern. However, virtually no work has been carried out in the influence of such factor. Therefore, in this study, according to rearing temperature, photoperiod and diet, variation of elytra color patterns were investigated. First instar larva on each color pattern were reared in an incubator at one of two temperatures; 25 and 30℃, under the following photoperiod; L16: D8, L12: D12 and L8: D16 and were provided three species of aphids. And their color pattern of adults were estimated.

The multicolored Asian ladybird beetle, Harmonia axyridis, which demonstrates typical genetic polymorphism in its elytra color patterns. Early studies have color polymorphism in terms of geographical clines while a few investigated temporal populations in Coccinellidae. Nevertheless, note that geographical and temporal morph variation does not always correspond to what is expected from thermal and industrial adaption theories. A recent study of transformation and RNAi of the ladybird beetle, however, there is yet no evidence to indicate the variation is genetic or environmental factors. Here we describe a relatively new molecular fingerprinting technique, amplified fragment length polymorphism (AFLP). Because we think that color polymorphism in Coccinellidae is affected by genetic polymorphism. In total 38 markers were scored from which some markers were polymorphic. Supsequent UPGMA cluster analysis revealed 3 major group of Harmonia axyridis populations. But for strains that are more genetically similar, different primer combinations may be need to generate enough polymorphic marker.

본 연구는 도시생태계 연구의 적지로 판단되는 경기도 성남시를 대상으로 습지 현황, 습지 유형, 습지식물의 특성, 그리고 훼손상태를 조사 분석하였다. 성남시의 도시습지는 1차 조사결과 모두 162개소가 확인되었으며, 입지적 특성에 따라 산간습지 55개소, 하천변 습지 4개소, 묵논 및 묵밭 62개소, 웅덩이 37개소, 저수지 4개소 등으로 분류되었다. 1차 조사결과, 습지로서의 잠재력이 있다고 판단된 107개소에 대해 2차 정밀 모니터링을 실시한 결과 약 39%에 달하는 42개소가 규모가 작고 육지화되어 습지의 가치가 매우 낮으며 매립 및 배수화 등으로 심각하게 훼손되고 있었다. 학술적으로 보전가치가 높은 중요 습지 27개소를 대상으로 수문환경 특성과 습지식물의 분포특성을 분석한 결과, 성남시 도시습지는 아직도 양호한 수환경 조건과 다양한습지식물의 분포와 정착환경이 형성되어 있는 것으로 나타났다. 그러나 조사된 184종류의 식물종 가운데 습지의존적인 식물은 75종류인 약 40.7%의 비율에 불과하며, 따라서 대부분의 습지가 육상역 식물종의 침입과 같은 인위적인 교란상태에 놓여있는 것으로 판단되었다. 이러한 사실은 습지식물 우세도 지수를 적용하여 습지의 보전상태를 평가한 결과에서도 성남시 전체의 경우 지수 값이 약 3.7로 나타나 습지평가유보 단계를 벗어난 양호한 육상생태계 수준에 근접하고 있는 것으로 분석되었다. 성남시가 중부내륙의 산악도시임을 감안할 때 전 지역에 고르게 분포하는 산간습지와 묵논 및 묵밭의 발달은 비록 규모는 작으나 육상과 수계 생태계사이의 생태적 추이대로 생태적 거점역할 측면에서 매우 중요할 것으로 판단되었다.

수업 중 발화의 대부분을 차지하는 것은 교사의 발화이다. 그러나 교사는 항상 교사의 입장에서만 말하는 것이 아니라 학생 발화와 유사한 발화를 통해 학생들의 수업에 도움을 줄 수 있을 것으로 생각되나 이에 대한 연구는 아직 부족한 것이 현실이다. 따라서 본 논문에서는 이러한 발화 형태를 유사학생발화라 명명하고, 유사학생발화가 다수 관찰될 것으로 예상되는 방송 수업(EBS의 2005학년도 중 1 과학 수업 중 지구과학 부분)을 연구하여 유사학생발화를 '수업 중, 학생 발화와 같은 역할을 하나, 교사를 통해 이루어지는 모든 발화의 통칭'이라 정의하였으며, Lemke(1990)의 학생발화분류를 토대로 연구 대상인 수업 중 나타난 유사학생발화를 교사가 개입하는 형태의 유사학생발화와 교사가 개입하지 않는 유사학생발화로 크게 유사학생발화를 나누고 교사 개입 유사학생발화로 유사 교사-학생 간 협의(Pseudo Teacher-Student Conferences), 유사 삼단계 담화(Pseudo Triadic Dialogue), 유사 교재 활용 담화(Pseudo External Text Dialogue), 유사 학생 질문 담화(Pseudo Student-Questioning Dialogue), 유사 교사-학생 간 담화(Pseudo Teacher-Student Dialogue), 유사 교사-학생 간 토론(Pseudo Teacher-Student Debate), 유사 실 담화(Pseudo True Dialogue), 유사 학생 상호 담화(Pseudo Cross Dialogue), 유사 동료 학생 발화 (Pseudo classmate talk)를, 그리고 교사 미개입 유사학생발화로 유사 학생 독백/유사 수업 중 잡담(Pseudo student monologue/Pseudo side talk)을 분류하였다. 또한 이러한 분류와 함께 각 유사학생발화의 실례를 소개하고 그 특징을 기술하였다.
