Morphological studies on larval hemocytes of varioius insects were performed in two ways of research. Ⅰ. Finestructures. An electron microscopical study on hemocytes of last instar larvae of 12 species of Lepidoptera was performed to observe cell types, structrues, raions, relationships and their origins. The results are as follows; 1) Prohemocytes are the smallest round cells with large numlesus, poorly developed cytoplasmic organelles and lower composition ratio, accounting for less than 5% of all cell types. Little remarked differences were revealed among prohemocytes of varous insects and they are thought to be the origins of other cell types. 2) Palsmatocytes are relatively large cells with higher composition ration, accounting for about 40%. They could be subdivided into two forms, oval and spindle. Oval cells are rich in cytoplasmic projections and organelles. But the spindle cells include few of them, while nearly all of the spindle cells possess some microtubules as their cytoskeletons. Some marked difference were revealed among different insects. The most exceptional structure was the fibrous bundles located in both nucleus and cytoplasm in Sericinus telamon Donovan. 3) Granular cells are characterized by various granules in cytoplasm, and by higher composition ration, accounting for about 50% of all numbers. They could be subdivided into three forms, oval, round and spindle with fully developed cytoplasmic organelles and Projections. Cellular fractions were often noticed to be enclosed by granular cells, indicating some activities of phagocytosis. Granular cells are the most pleomo rphous of all cell types, and the most exceptional structures are the bundles of microfibrils in Phalerodonta manleyi Leech. 4) Adipohemocyte were found only in Plodia interpunctella Hubner. They are somewhat oval with few cytoplamic projections and less developed organelles. Some granular cells were found to accumulate lipid droplets into the cytoplasm by trapping floating lipid droplets, adn the adipohemocytes are believed to be originated from formers. 5) Sperule cells were found nearly in all specimens and characterized by sperules composed of flocculent materials. They are round or oval with few cytoplasmic organelles. The most conspicuous spherulesof all sperule cells were radial arrangement of sperules in Adristyrannus amurensis Staudinger and presence of the specific granules in Mamestra illoba Butler. Young sperule cells resembled the granular cells and it is possible that they originate from granular cells. 6) Oenocytoids are large cells and were found nearly in all specimens. They could be subdivided into 3 types according to their inclusions, such as microfibrils, microtubules and none of them. Young Oenocytoids resemble the giant plasmatocytes, perhaps in dicating to be originated from the latters. Ⅱ. Composition ratios of cell types from mid 5-instar to late prepupa. Composition ratios of cell types were investigated in phalerodonta manley; Leech and could be summarized as follows; 1) Prohemocytes disappeared from the stage of early prepupa. 2) Plasmatocytes increased in number at mid stages of each inster and decreased nearing to pupal stage. 3) Granular cells reached peak at early prepupal stage. 4) Adipohemocytes heavily increased at late prepupal stage. 5) Sperule cells increased at late stage of each instar and reached peak at late prepupal stage. 6) Oenocytoids increased at late stage of each instar and reached peak at early prepupal stage.

The Insurance Contract Law is private law, but nevertheless it restricts the principle of private autonomy by the Article 663 of Commercial Law. Under the Article 663 any special free contract between parties is not allowed, except reinsurance, marine insurance and other similar kinds of insurance policies. In this study I examine some serious problems of peremptory notice under the Article 650 Clause 2 regarding the principle of the disadvantage forbidden alteration.

배추흰나비 食道下神經節의 神經細胞에 관한 形態學的 硏究

梁熙永,李鳳熙,金宇甲 순천향대학교 1985 논문집 Vol.8 No.1

The study on the nerve cells in the subesophageal ganglion of adult cabbage butterfly (Pi-eris rapae L.) was performed to observe their structural characteristics. The subesophageal ganglion which had been associated to rear part of brain in the process of metamorphosis of larva to pupa was consisted of neuropile in the central region and nerve cell bodies in the rind. The nerve cell bodies were divided into three types on basis of their shapes, sizes and presence of neurosecretory granules, etc. In type I nerve cells the sizes of their cell bodies were 9.5 to 14.5μm in diameter and those of their nuclei were 7.0 to 12.0μm. The type I nerve cells which were the most typical neurons of brain nerve cells from cabbage butterflies had round or ellipsoid shapes. The type Ⅱ nerve cells had a variety of shapes, i.e., round, ellipsoid or triangle, and their sizes were 14.5 tp 20.0μm in diameter. The type Ⅱ nerve cells which included a number of neurosecretory granules were considered neurosecretory cells. The type Ⅲ nerve cells had the smallest sizes of approximately 4.5μm in diameter and their nuclei were about 2.5μm. These cells had no secretory granules in their cell bodies.

An Easy Approach to Conversation

Yang,He-young 한국항공대학교 1982 論文集 Vol.20 No.-

In the given situations in Korea, it is extremely difficult for adults to learn to speak the sopken English accurately and naturally by the inductive method. For developing the ability to use the spoken English properly, adult students should be taught the fundamental principles in learning English which are described her by the deductive method. after the habit-formation of these principles, they would be aboe to learn English through the self-instruction. Practice must parallel theory inlearning the spoken language. The ideal thing, i it can be arranged, is to give the students and opportunity, one or two of them at a time, to meet and talk with a group of English-speaking people, and to let them listen and join in the conversation. But in our situations, it may be impossible for the students to have such a favorable opportunity either inside or outside the classroom. In teaching conversation to children the inductive method should be used if a teacher familiar with the technique is abailable. But it is a fallacy to suppose that adults can learn a foreign language in the same way as children do, unless they learn it in the country where it is spoken. Most adult students find the inductive method unsatisfying and are not content to wait for the rules to emerge fro the particular instances. Most of them probably know that rules of grammar and syntax are a common feature of all civilized languages. it is essential for the adult to learn something of the pattern of a new language, its grammatical and syntactical framework, and it is natural for him to learn a language deductively since in any language there are rules to learn. He is sure that he is saving time by learning rules from te start instead of deriving a knowledge of them inductivel. Therefore, they should deductively learn the spoken English thourhg havit forming practice. The following are intended to suggest ways in wyich the spoken language can be learned easily ad put to practical use.

A Hybrid Fault Diagnosis Approach for Hydraulic Systems by using Radial basis Function Networks

Xiang-yu He,Yijiao Yang,Shanghong He 보안공학연구지원센터 2014 International Journal of Control and Automation Vol.7 No.12

To improve the reliability of hydraulic systems, a fault diagnosis approach based on radial basis function (RBF) networks was proposed in this paper. According to the target fault features extracted from a fuzzy auto-regressive with extra outputs (FARX) model, RBF networks serve as a fault classifier and the output of the RBF networks is the result of fault diagnosis. Several typical faults of hydraulic systems were used to test the fault diagnosis approach. Experiment results showed that the fault diagnosis approach is feasible and effective for improving the reliability of hydraulic systems.

Yan, Yue,Zhang, Ya-Xiong,Fang, Wen-Feng,Kang, Shi-Yang,Zhan, Jian-Hua,Chen, Nan,Hong, Shao-Dong,Liang, Wen-Hua,Tang, Yan-Na,He, Da-Cheng,Wu, Xuan,Zhang, Li Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.2

Background: Differentiating morphologic features based on hematoxylin-eosin (HE) staining is the most common method to classify pathological subtypes of non-small-cell lung cancer (NSCLC). However, its accuracy and inter-observer reproducibility in pathological diagnosis of poorly differentiated NSCLC remained to be improved. Materials and Methods: We attempted to explore the role of immunohistochemistry (IHC) staining in diagnosing pulmonary squamous cell carcinoma (SQCC) with poorly differentiated features by HE staining or with elevated serum adenocarcinoma-specific tumor markers (AD-TMs). We also compared the difference of epidermal growth factor receptor (EGFR) mutation rate between patients with confirmed SQCC and those with revised pathological subtype. Logistic regression analyses were used to test the association between different factors and diagnostic accuracy. Results: A total of 132 patients who met the eligible criteria and had adequate specimens for IHC confirmation were included. Pathological revised cases in poor differentiated subgroup, biopsy samples and high-level AD-TMs cases were more than those with high/moderate differentiation, surgical specimens and normal-level AD-TMs. Moreover, biopsy sample was a significant factor decreasing diagnostic accuracy of pathological subtype (OR, 4.037; 95% CI 1.446-11.267, p=0.008). Additionally, EGFR mutation rate was higher in patients with pathological diagnostic changes than those with confirmed SQCC (16.7% vs 4.4%, p=0.157). Conclusions: Diagnosis based on HE staining only might cause pathological misinterpretation in NSCLC patients with poor differentiation or high-level AD-TMs, especially those with biopsy samples. HE staining and IHC should be combined as pathological diagnostic standard. The occurrence of EGFR mutations in pulmonary SQCC might be overestimated.

A Study on Punctuation

Yang, He-young 한국항공대학교 1978 論文集 Vol.14 No.-

Speech consists not merely of sounds but of organized sound sequences that follow various structural patterns and are pronounced with modifications of pitch and stress and pauses. Punctuation marks as the signposts of the English writing system, which, in a broad sense, include italics, capitals, and so forth, are used in order to separate groups of words and to indicate the varying pitch and volume and especially the pauses in the stream of speech sounds. Thus, punctuation marks are sometimes as important to clear and effective communication as the words or the tone one uses. Although English punctuation was primarily rhetorical until the eighteenth century, in Modern English, punctuation has become more systematized, working largely in a set of relatively consistent practices intended to clarify meaning in writing and to help mark the grammatical structure of the sentence. Consider the following: If she plans to be married, before she is twelve she should have started a hope chest. If she plans to be married before she is twelve, she should have started a hope chest. The American soldiers who had been hiding in the old barn were all killed. The American soldiers, who had been hiding in the old barn, were all killed. Many points concerning punctuation are largely a matter of style, but there are certain principles that may serve as a guide. The meaning and function of the various punctuation marks and their actual use in current writing are explained below.
