  • 낙지는 우리나라 연안에 대부분 서식하는 종으로 특히 남해안 연안에서 많이 어획되고 있는 종이다. 현재, 중국산 낙지가 우리나라 수산시장에 많이 수입되고 있는 관계로 본 연구에서는 분자마커를 이용하여 한국산과 중국산 낙지를 구별하기 위하여 조사했다. 유전자 증폭을 이용하여 중국 산동지역에 서식하고 있는 낙지 4마리에 대하여 PCR 생성물이 보인 반면에, 남해, 무안, 여수, 진도에 서식하고 있는 낙지 미토콘드리아 DNA는 나타나지 않았다. 따라서 PCR 증폭으로 국내산 $1{\mu}g$ DNA 첨가 시 중국산 0.1 ng DNA까지 민감도를 보여, 앞으로 간편하고 신속한 중국산 낙지 구별을 위하여 좋은 도구로 이용될 것으로 보인다.

  • 농약의 마이너 사용 이슈는 국내에서 뿐만 아니라 외국에서 그리고 국제적으로도 그 해결책이 요구되고 있다. 더 나아가 마이너 사용에 대한 정의가 나라마다 다르고, 또 주요 작물(major crop)과 마이너 작물(minor crop)이냐에 따라 농약 사용 등록 및 규제에 차이가 있게 되므로 농약 관리에서의 어려움이 가중된다. 여기에서는 마이너 사용에 대한 정의, 국내외 마이너 사용 프로그램, 마이너 사용 등록 장려 방안 등에 관한 정보를 제공함으로써 국내 마이너 사용 이슈를 해결하는 데 도움이 되고자 하였다. 그리고 결론적으로 다음의 두 가지 내용을 제안한다. 첫째로 국내에서 법적으로 마이너 사용을 정의하는 데 신중함이 필요하며 그 정의에는 소면적 재배 작물뿐만 아니라 그 외 마이너 사용에 대한 모든 상황들이 포함되도록 한다. 그리고 둘째로 현재 실시하는 소면적 재배작물의 직권시험을 기반으로 한 더 강력한 마이너 사용 프로그램이 구축될 필요가 있다. OECD 지침에서 제시한 바와 같이 미국의 IR-4 Project와 같은 협력 프로그램을 도입한다면 농약 마이너 사용 프로그램을 보다 더 효과적으로 운영할 수 있게 될 것이다.

  • As public acceptance of nuclear energy in Korea worsens due to the Fukushima accident and the earthquakes that occurred in the Gyeongju area near the Wolsong nuclear power plant (NPP), estimating the effects of earthquakes has become more essential for the nuclear industry. Currently, most countermeasures against earthquakes are limited to large-scale disasters. Minor-scale earthquakes used to be ignored. Even though people do not feel the shaking due to minor earthquakes and minor earthquakes incur little damage to NPPs, they can change the environmental conditions, for instance, underground water level and the conductivity of the groundwater. This study conducted a questionnaire survey of residents living in the vicinity of an NPP to determine their perception and acceptance of plant safety against minor earthquakes. The results show that the residents feel earthquakes at levels that can be felt by people, but incur little damage to NPPs, as minor earthquakes (magnitude of 2.0-3.9) and set this level as a standard for countermeasures. Even if a minor earthquake has little impact on the safety of an NPP, there is still a possibility that public opinion will get worse. This study provides analysis results about problems of earthquake measures of Korean NPPs and specific things that can bring about an effect of deterioration of public acceptance. Based on these data, this article suggests that active management of minor earthquakes is necessary for the sustainability of nuclear energy.

  • The flank wear at the minor cutting edge significantly affects the geometric accuracy and surface roughness in finish machining. A fuzzy estimator based on a fuzzy inference algorithm with a max-min composition rule is introduced to evaluate the minor flank wear length. The features sensitive to minor flank wear are extracted from the dispersion analysis of a time series AR model of the feed directional acceleration signal. These features, dispersions, are used for constructing linguistic rules, and then the fuzzy inferences are carried out with test data sets collected under various cutting conditions. The proposed system turns out to be effective for estimating minor flank wear length.

  • 생성의 입장에서 바라보는 죽음은 소수 교육철학의 형성에 기여한다. 소수 문학에 대한 탐구는 이 관계를 확고하게 해준다. 들뢰즈와 가타리의 소수 문학이란 소수 언어로 쓰인 문학을 말하는 것이 아니라 오히려 소수자들이 다수언어로 만들어내는 문학을 말한다. 그들은 카프카의 작품들을 그 전형으로 내세운다. 카프카의 작품들은 궁극적으로 이 생성(devenir)으로서의 죽음을 말한다. 죽음과 소수 문학은 강도(intensité)라는 이론적 도구를 공유함으로써 서로를 전제하는 것으로 파악된다. 소수 교육철학은 이런 주장을 좇아 그 가능성이 제기된다. 이는 잘 포장된 상품으로서의 지식을 전달하는 일에만 만족하는 현대 교육철학자들의 정체성에 의문을 제기하고, 특정한 방식으로만 철학자들을 독해하도록 강요하는 주류 교육철학에 맞선다. 우리는 이 가능성을 정동(affect)으로서의 언어에 입각한 교육활동을 통해 제기해 볼 수 있다.

  • The response changes of the specific growth rate of Lemna minor duckweed was modeled using the logarithms of frond numbers on tritium activity concentration and gamma radiation dose from cobalt 60. The concept of average specific growth rate depends on the general exponential growth pattern, where toxicity is estimated based on the effect on the growth rate. One of the main questions of the effect of the radiation dose on duckweed is how to correlate the effect of beta radiation with the effect of any other radiation for modeling radiation on Lemna minor. Experimental data were extrapolated by utilizing the OECD guidelines. A linear relationship of absorbed dose and activity concentration was obtained for the average dependency growth rate of Lemna minor as D = (0.1257)·A0.585. The dose rate of gamma irradiation from 60Co increases with tritium activity dependence, on the specific growth rate of the Lemna minor duckweed. An increase in the tritium activity causes a decrease in the specific growth rate of the Lemna minor duckweed. It indicates that as the quantity of the beta radiation dose increase in Lemna minor duckweed, a higher quantity of gamma radiation will be required to cause the same effect in the specific growth rate of Lemna minor duckweed. The relation between the inhibition of the Lemna minor seedling growth and gamma and beta radiation dosage agrees roughly with that between the decrease of survival rate or fertility and dosage.

  • The nutritional worth of Phalaris minor seeds was assessed in comparison to conventional cereal grains like maize and wheat. P. minor seeds had higher total ash and cell wall constituents as compared to wheat and maize grains. The CP content of P. minor was comparable to wheat grains but higher than maize grains. The in vitro studies revealed that the net gas production and availability of ME from P. minor was comparable to that of maize but the digestibility of nutrients was significantly (p<0.05) lower than that of conventional cereal grains. The digestion kinetic parameters for DM and CP revealed that P. minor had the highest (p<0.05) soluble fraction (a) followed by wheat and maize. Reverse trend was observed for insoluble but potentially degradable fraction (b). The effective and true DM and CP degradability was significantly (p<0.05) higher in wheat grains followed by that in P. minor and maize grains. The digestibility of OM and NDF was not affected by replacing cereal grains in concentrate mixture with P. minor seeds up to 75 per cent level. But the availability of ME from concentrate mixtures was comparable to control only up to 50% level of replacement. Replacement of cereal grains with P. minor did not affect the rapidly soluble fraction and insoluble but potentially degradable fraction of concentrate mixture containing P. minor up to 75 per cent, but it was depressed significantly at 100% replacement level. The effective and true degradability of DM of concentrate mixtures containing P. minor from 50 to 100 per cent was comparable to that of conventional concentrate mixture (CCM). The wheat based concentrate mixtures showed higher net gas production (208 vs. 201 ml/g DM/24 h), digestibility of nutrients and ME availability (9.64 vs. 9.54 MJ/kg DM) as compared to maize based concentrate mixture. The wheat based concentrate mixture had significantly (p<0.05) higher rumen undegradable fraction and effective degradability. The data conclusively revealed that conventional cereal grains could be replaced with P.minor seeds up to 75 per cent without affecting the availability of nutrients.

  • The authors reviewed 114 cases of malignant major and minor salivary gland tumors at Presbyterian Medical Center seen from February, 1963 to December, 1983. The results were obtained as follows; 1) Overall male and female sex ratio was 2:1. The peak age of patients with major and minor salivary gland tumor were both 5 th decade. 2) The ratio of benign and malignant tumor was 83:114. The incidence of malignancy in each group was 52% in parotid (50 patients), 75% in minor salivary gland (45 patients), 49% in submaxillary gland(18 patients) and 25% in sublingual gland (1 patient). 3) The incidence according to the anatomic primary site for minor salivary cancers was 10 cases in the nasal cavity, each 8 in the palate and the maxillary antrum, 7 in the tongue, 5 in the gum, 3 in the larynx and 2 in the buccal mucosa. 4) Adenoid cystic carcinoma was the most common cancer of minor salivary gland and malignant mixed tumor was the most common in major salivary glands, each comprising 34 cases (76%) of minor and 19 cases (28%) of major salivary gland tumors. 5) The incidence of cervical lymph node metastasis was 50% in the submaxillary gland cancers, 44% in the parotid gland cancers and 21% in malignant tumors of minor salivary glands. The highest incidence of lymph node metastasis according to histopathological classification was formed in high grade of mucoepidermoid (67%). 6) Nerve invasion was common in mucoepidermoid carcinoma. According to anatomic site, nerve invasion occurred most often in adenoid cystic carcinoma of the submaxillary gland (44%). 7) The lung was the commonest site for distant metastasis comprising 12 cases among 26 cases in which distant spread occurred. 8) The recurrence rate was 50% for major salivary gland cancer and 52% in cancer of the minor salivary gland. In accordance with pathological classification, adenocarcinoma most frequently recurred after excision. This being seen in 88% of patients undergoing definitive therapy. 9) The determinate 5 year survival rate was 78% in major salivary gland tumors, but 69% in minor salivary gland tumors.

  • There are some patients who have traumatic anterior shoulder instability due to minor injuries like overhead activities. The purpose of this study was to clarify characteristic features of traumatic anterior shoulder instability due to minor injuries. According to the mechanism of injury in an initial dislocation, 83 shoulders that underwent the stabilizing surgery for traumatic anterior shoulder instability were divided into two groups. Traumatic group included patients who suffered from a fall or a direct injury. Minor injury group included patients who suffered from the other injury like overhead activity. General joint laxity, range of motion and laxity under anesthesia, and intraarticular findings were compared between two groups. The morphology of superior and middle glenohumeral ligaments, Bankart lesion, Hill-Sachs lesion, and partial articular surface tendon avulsion lesion were observed in arthroscopy. Minor injury group consisted of 19 shoulders with 8 males, 11 females and the mean age of 22.5 years. Traumatic group consisted of 64 shoulders with 52 males, 7 females and the mean age of 24.3 years. Female in minor injury group was significantly more than that in traumatic group. There was no difference in general joint laxity and intraarticular findings between two groups. Range of external rotation in injured side in minor injury group was significantly more than that in traumatic group. Inferior laxity in both sides in minor injury group was more than that in traumatic group. In conclusion, the traumatic anterior shoulder instability due to minor injuries might incline to occur the shoulder in female and with inferior laxity of shoulder.
