Food intake of birds can be affected by particle size as well as diet composition, In order to investigate whether food intake of diets including excessive amount of phenyalanine(Phe) was influenced by diet types. a series of experiments were conducted in growing chicks and laying hens. Growing chicks significantly decreased food intake in a semipurified excessive Phe diet compared with a semipurified control diet, while laying hens fed a practical diet including excess Phe did not significantly reduce their food intake over a corn starch-substituted control diet. In an attempt to find out whether diet type affects food intake in layers, the semipurified type diet with excess Phe greatly reduced food ingestion, but the effect was delayed in the practical type diet. Moreover, under choice feeding regimes between the Phe and either starch, tyrosine(Tyr) or fiber diets in order to investigate whether the decreased food intake in the presence of an excess of dieary Phe in laying hens is involved in the palatability for the diet, there was no significant difference between Phe and starch diet while a preference for the Phe diet tended to be increased when birds were offered Tyr. Laying hens ingested significantly more the Phe diet than the fiber diet within 1 h after feeding. For supporting the idea that preference for the Phe diet may be affected by manipulating taste sense, an anaesthetic or saline was intramuscularly administered under the tongue just before a choice feeding. Preference for the Phe diet was not significantly different from that for the fiber reference diet within 1 h in the anaesthetized birds while the birds preferred the Phe diet in the saline treated group. It is suggested that because birds are able to select a diet, the decreased food intake induced by dietary excess Phe may be due to the repulsive effect of Phe after ingestion but not the taste of Phe.

The actual burden of head and neck cancer in India is much greater than reflected through the existing literature and hence can be regarded as a 'tip of iceberg' situation. This has further been evident by the recent reports of 'Net-based Atlas of Cancer in India'. South-east Asia is likely to face sharp increases of over 75% in the number of cancer deaths in 2020 as compared to 2000. Since the percentage increase of Indian population has been nearly twice that of the world in last 15 years there is a likelihood of increase in cancer burden with the same proportion. The distribution of population based cancer registries is grossly uneven with certain important parts of the country being not represented at all and hence the current cancer burden is not reflected by registry data. However, the pathetic situation of health care system in major parts of the country as also emphasized by the World Bank, is not suitable to provide anywhere near accurate data on cancer burden. Head and neck cancer (including thyroid lesions) is third most common malignancy seen in both the sexes across the globe but is the commonest malignancy encountered in Indian males. Also oral cavity cancer is the most prevalent type amongst the males and one of the highest across the globe. This article reviews the latest global and national situation with an especial emphasis on head and neck cancer. Furthermore this review focuses on burden in different sub sites at national and global levels.

The purposes of this study are two-folds: to find out the acoustic features of Korean stops in various utterance positions and their influence on the neighbouring segments. Korean stops($/p,\;p',\;p^{h};\;t,\;t',\;t^{h};\;k,\;k',\;k^{h}/$) are examined from CV, $V_1CV_2,\;V_1NCV_2,\;V_1LCV_2$ sequences. Three speakers (two male and one female speakers of Seoul dialect) served as subjects for the present study. VOT, closure duration of the target stops and duration of the neighbouring segments were measured from acoustic data. The results can be summarized as follows. First, stops show different temporal aspects depending on their place of articulation as well as their voice types. Velar stops tend to have shorter closure duration and longer VOT due to relatively slower movement of the articulator (i.e. tongue body) and higher supraglottal air pressure during the closure, respectively. Second, temporal aspects of the neighbouring segments appear to be influenced by the voice type of stop. The preceding segment tends to be longer when a stop has shorter duration. On the other hand, the following segment tends to be shorter, when a stop has longer VOT.

Urticaria is an erythematous or white non-pitting edematous plague that changes in size and shape by peripheral extention or regression during the few hours or days. Urticaria is classified as acute or chronic type. The etiology of acute urticaria has been determined in many case, but the cause of chronic urticaria has been determined in only $5\%\;to\;20\%$ of cases. This observation was aimed to evaluate the clinical manifestations and clinical indence of urticaria seen between June, 1995 and November, 1996(18months) at the Department of Dermatology, Oriental Medical Hospital, Kyung Hee University. The results were summarized as follows ; 1. In the cases of 106 patients, $43\%\;were\;male\;and\;51\%$ were female. 2. The pick incidence of age group was 20 to 29($32\%$). 3. The most frequent duration of urticaria was from 2 months to 6 months. 4. In this study, the inciting causes could not be found in $61\%\;of\;acute\;patients,\;60\%$ of chronic patients. 5. Among 107 patients, $5\%$ of all patients had personal history of atopic diseases and $9\%$ of all patients had familly history. 6. Angioedema was founded in 7 patients, and the most common involved site were lips, eyelids and tongue. 7. The most frequently treated prescription was Chhunggisan which occupied $51\%$ of all, Gyakhangjunggisan(41\%$) and Gosamhomasan($25\%$), Bangpoongtongsungsan($22\%$) in that order of frequency.

Experimental investigations of interlaminar mechanical properties for carbon fiber reinforced plastic (CFRP) laminates were carried out using aramid fiber ($Kevlar^{(R)}$-29 1000d) and carbon fiber (TR40-1K 612d, Mitsubishi Rayon) stitching. Various carbon fiber (CF) stitch densities were used to prepare a number of CF stitched CFRP laminates for double cantilever beam (DCB) tests. An insert tongue-type loading fixture, developed by the Japan Aerospace Exploration Agency (formerly the National Aerospace Laboratory of Japan), was also employed in the DCB test. Interlaminar tension tests were carried out under an out-of-plane directional loading using a single CF stitch thread in the CFRP laminates. The DCB test results clarified that the relationship between the volume fractions of the CF stitch thread ($V_{ft}$) and mode I critical energy release rate ($G_{Ic}$) showed a mostly linear function with a higher gradient than that of the $Kevlar^{(R)}$ stitched CFRP laminates. The CF stitched CFRP tension test results indicated that the consumption energy per unit area ($E_i$) was larger than that of $Kevlar^{(R)}$ stitched CFRP laminates.

Several investigators have shown that human papillomavirus(HPV) appear to play an etiologic role in oral and paranasal sinus carcinoma. It was known that 15-25% of head and neck squamous cell carcinoma(SCC) showed HPV-positive infection. Among them, HPV 16 was the most common type but HPV 18 was observed only 2-4% of HPV-positive head and neck cancers. In recent, we treated uncommon 2 oral SCC cases that associated with HPV infection. One is a case of tongue SCC after bone marrow transplantation(BMT), and the other is a case of SCC occurring with aspergillosis in the maxillary sinus. After surgery, HPV 16 and 18 were detected in the surgical specimens by the histological and polymerase chain reaction(PCR) examination. In this report, we present these cases with a review of literature.

In China, elder brother's wife is called 'Sao' or 'Saozi' and younger brother's wife is called 'Fu' or 'Difu', etc. On the other hand, In Korea is called 'Hyeongsu' and 'Jesu'. This paper aims to find that Korean and Chinese kinship terminology 'Hyeongsu' and 'Jesu's origin and characteristics. And considerd reason that Korean kinship terms different changed with Chineses and investigated whether the presence of native language. In China, Kinship term reflected strict species act. Therefore, for elder brother's wife to give dignity 'Sao' in the title that made separately. In other hand, sister-in-law used 'Fu that means submission. The first was to use the same type of Kinship terms in the Korean and Chinese. Because Korea accept of the China's relative terms. But gradually confusion about the meaning of the original issued 'Sao' and wrong term 'Jesu' appeared. In response, 'Hyeongsu' as a two-syllable terms was shown whence they came. Also through literature shows that '아??마', '아??마니 is called native tongue.

This paper addresses the question of why prepositions are particularly difficult forEFL learners. The first reason for such difficulty lies in the distinction between seemingly equivalent prepositions such as to and with, as in compared to and compared with. Most monolingual learners' dictionaries regard these two phrases as virtually synonymous. Yet, the results of the corpus analysis conducted in this study indicate that there are differences between the two. A second reason why EFL learners have problems with prepositions is that there are often variations in the inputdata. For example, although from generally follows different, in American English different than is also used. On the other hand, in British English, different to is the second most commonly used construction. This type of regional variation, confirmed in the corpus findings of the present paper, causes confusion in students of English. A learner who is not accustomed to British English may be puzzled by the expression different to. Finally, L1 negative transfer is responsible for the incorrect use of expressions such as discuss about. An error of this sort is the result of interference from the learner's mother tongue. The English verb discuss is not subcategorized for a preposition, whereas the equivalent Korean verb, for example, requires a noun phrase combined with the postposition.
