The teleosts represent ancient real-bony vertebrates in phylogeny and resemble major genetic patterns to higher vertebrates. In the present study, we have defined the single family of insulin-like growth factors (IGFs) from flounder (Paralichthys olivaceus), compared to the prototype of IGFs observed in the Agnathan hagfish. In flounder, IGFs are clearly diverged into two major types including type I and II, and they are structurally similar by displaying a multidomain structure consisting of five functional regions as previously found in other vertebrates. However, flIGF-I appears to be more basic (pI 8.03) than the flIGF-II (pI 5.34) in the fully processed form for the B to D domain region. The flIGF-I seems to contain an evolutionary conserved Asn-linked glycosylation in E domain, which is not found in flIGF­II. The most interesting feature is that flIGF-II appeared to be structurally close to hagfish IGF in secondary structures, particularly in Band D domains. This could tell us an idea on the molecular divergence of IGFs from the Agnatha to teleosts during the vertebrate phylogeny. It also support, in part, a notion regarding on how IGF-II is appeared as more embryonic during development. Nonetheless, the biologically active B to D domain region of flIGF-II shows significant sequence homology of $65.6\%$ to flIGF-Is and contains the evolutionary conserved insulin-family signature, as well as a reserved recognition site (Lys) in D domain, necessary to generate proteolytic cleavage for E-peptide. A significant structural difference was found in E domain in which flIGF-I possesses two potential alternative splicing donor site at $Val^{17,\;24}$ of E domain. Therefore, it seems so far that IGF-I sorely produces spliced variants due to the spliced E-peptide moiety while IGF-II appears to be maintained in a single type during evolution. IGF-II, however, may be also possible to transcribe unidentified variants, depending on the physiological conditions of tissues in vertebrates in vivo.

Objectives : The 7-zone-diagnostic system is a device for predetermining bodily locations by measuring the energy of the living body. The purpose of this study is to examine correlations between gastroscopy results and zone-5 data from the 7-zone-diagnostic system. Methods : This study was carried out with data from gastroscopy procedures. It involved 115 patients who had been diagnosed with gastritis, esophagitis, or gastric ulcers. These patients were divided into three groups according to the different patterns of zone-5 factors AA, FL2 and FL1. Group A was made up of patients for whom the red bar graph of zone-5 was higher than the normal range for factor AA. Group B was made up of patients for whom the red bar graph of zone-5 was within the normal range for factor AA. Group C was made up of patients for whom the red bar graph of zone-5 was lower than the normal range for factor AA. Group D E and F were made up of same way as group A B and C for factor FL2. Group G H and I were made up of same way as group A B and C for factor FL1. After the collection of gastroscopy results and data on zone-5 from the 7-zone-diagnostic system, the data was analyzed statistically. Results : 1. Group D had a higher ratio of medication than group E, and this result was statistically significant. 2. Group D G had a higher ratio of medication than group E G and group E H, and this result was statistically significant. 3. Group G had a higher ratio of esophagitis than group H, and this result was statistically significant. 4. A Group B H had a higher ratio of esophagitis than group B G, group C G, and group C H, and this result was statistically significant. 5. The medication group had a high score on the function index than the non-medication group, and this result was statistically significant. Conclusions : This study suggests that there is a slight correlation between gastroscopy results and zone-5 data from the 7-zone-diagnostic system. The research resulted in significant data that are helpful for diagnosing digestive system problems through the use of the 7-zone-diagnostic system.

Comparative studies regarding the nutritional status of 93 home-living elderly people taking free congregate lunch meals(FL) and 87 middle income class elderly people(MI) were performed in Taejon city. Data was obtained from questionaires, anthropometry and interviews for the 24-hour dietary recall of 2 nonconsecutive days during August, 1996. The average age for FL was 75.8 years. The monthly familly income for FL belonged to the low-income class. FL females had lower heights and weights than MI females. The average daily nutritional intake of both FL and MI were low, particularly in FL whose %RDA of energy was 68.5%, protein 65%, Ca 29.6%, Fe 50.8%, vitamin A 34.5%, vitamin E 30.5%, riboflavin 40.6%, vitamin C 76.9%. MI's %RDA of energy was 76.4%, protein 80.a2%, Ca 48.1%, Fe 78.6%, vitamin A 67.3%, vitamin E 117.4%, riboflavin 45.6%, vitamin C 136.5%. Comsumption of Zn, vitamin $B_6$ and folic daily average. There was no nutrient having average INQ(Index of nutritional quality) over 1 for either group. The INQs for protein, Ca, Fe and vitamin A were 0.802, 0.377, 0.625 and 0.296 in FL, and 0.900, 0.601, 0.784 and 0.602 in MI, respectively. The MAR(Mean adequacy ratio) was low with the value of 0.500-0.518 in FL and 0.630-0.723 in MI. The percentage of main nutrients from lunch was the highest among the three meals for FL males, while that from breakfast was the highest for MI. Free lunches taken by FL supported higher percentages of main nutrients than home-lunches taken by MI. Eating-out was done more frequently by MI than by FL and that eating-out brought them more nutritional intake. The above data indicated that the dietary nutritional intake status of the FL elderly was very poor in both quantity and quality and that free congregate lunch significantly contributed to the daily nutrient-intake for the FL elderly.

The insulin-like growth factor (IGF) is found in all vertebrates and its type-II molecule is regarded as a fundamental embryonic growth factor during development. We have firstly identified, in this study, a cDNA clone corresponding to IGF-II (flIGF-II) from the adult brain of the teleost, Paralichthys olivaceus. We also examined the tissue expression of flIGF-II in several adult tissues by RT-PCR. The flIGF-II cDNA contained a complete ORF consisting of 215 amino acids and one stop codon. Its molecular characteristics appear to be similar to the previously identified IGF-II molecules, in which a common primary structure exhibiting B, C, A, D, and E domains is evidently observed. This cDNA clone seems to be cleaved at $Ala_{52}$ for the $NH_2$-end signal peptide and appears to produce a 98 amino acid-long E-peptide from the $Arg^{118}$. The functional B-D domain regions, therefore, include 65 amino acids and is able to encode a 7.4-kDa protein. The most prominent structural difference between IGF-I and IGF-II was that the D domain of IGF-II exhibits a two-codon-deleted pattern compared to the 8 amino acid-containing IGF-I. The insulin family signature in the A domain and six cysteins forming three disulfide bridges between the B and A domains were evolutionary-conserved from teleosts to mammalian IGF-II. Interestingly, the E-peptide region appears to provide a distinct hallmark between teleosts in amino acid composition. The flIGF-II shows 85.1% of sequence identity to salmon and trout, 90.6% to tilapia, and 98.4% to perch in amino acid level. In tissue expressions of IGF-II, it is very likely that flIGF-II has a significant expression in the adult brain. However, liver seems to be the main source for IGF-II production, and relatively low signals were observed in the adult muscle and kidney. Taken together, it would be concluded that the functional region for IGF-II mRNA is highly similar in phylogeny and is evolutionary, conserved as a mediator for the growth of vertebrates.

Using differential display reverse transcription technique, the present study attempted to isolate and characterize genes specifically expressed in cotyledons of Pharbitis nil Choisy cv. Violet during floral induction. A total of 107 bands specific to the inductive condition were initially obtained with 80 primer sets of 20 different arbitrary primers combined with 4 kinds of T12MN. In northern blot analysis with reamplified cDNAs as probes, three cDNAs were detected to be expressed specificcally in the induced cotyledon tissues, and designated PnFL-1, PnFL-2 and PnFL-3 , the size of which were 228 bp, 317 bp and 272 bp, respectively. A search for sequences similar to the decuced amino acid sequences was conducted using GenBank and EMBL database ; seequence encoded by PnFL-1 had 29% identity with the clone of Arabidopsis thaliana similiar to reverse trascriptase (Genbank Acc. N0.3047086), PnFL-2 shared 50% identity with hydroxiyproline-rich glycoprotein of Glycine max(GenBank Acc. No.347455), and PnFL-3 had 46% identity with TAMU 4. Thaliana genomic clone T23E16 (GenBank Acc. No.B67574). None of them was known gene in the plant system up to date, implying that the fragments may comprise parts of genes which are associated with the floral induction in Pharbitis nil.

Cheongkukjang is a traditional fermented soybean food in Korea that is used in the manufacture of functional foods. This study was conducted to assess vitamin contents and sensory qualities of powdered Cheongkukjang dried by oven drying, far-infrared drying and freeze drying. Vitamins $B_1$, $B_2$, $B_6$, E, niacin and pantothenic acid were detected using all drying methods. However, vitamin D was not detected in the oven drying samples, and was most prevalent($82.47{\mu}g$/100 g) in the far-infrared drying samples. The sensory characteristics included color, off flavor, salty taste, bitter taste, sweet taste, roasted taste and after-taste. Oven drying and freeze drying samples exhibited highest and lowest color scores(5.62 and 2.0, respectively). Oven drying samples also exhibited the highest roasted taste score(4.76), although not significantly different from far-infrared drying samples(4.0, p<0.05), while the score of freeze drying samples(2.38) was significantly different from the other methods(p<0.05). It is concluded that freeze drying is most suitable.

본 논문에서는 소프라노가 성악 발성으로 한국어 단모음을 발음할 때, 그 단모음들의 포르만트가 F0(Fundamental frequency)에 따라 어떻게 바뀌어지는지 연구되었다. 일반적으로 다른 파트의 경우와는 달리, 소프라노가 노래를 할 때에는 포르만트가 그 F0의 영향을 크게 받는 것으로 알려져 있다. 따라서, 성악발성에 대한 연구를 위해서는 소프라노가 발성할 수 있는 전 음역 대의 F0에서 각 모음에 대한 포르만트 분석이 필요하다. 이러한 분석 결과를 바탕으로 성악 발성의 특징들을 패턴화하여 성악발성 평가 시스템이나 성악발성 합성 시스템을 구축할 수 있다. 5명의 전문 소프라노를 대상으로 '아, 에, 이, 오, 우' 5모음의 성악발성을 A3(220.0Hz)에서부터 A5(880.0Hz)까지의 피치에서 포르만트 분석을 하였다. 또한, 일반적인 대화 시 이 5가지 모음의 포르만트를 분석하여 성악발성의 경우와 비교하였다. 연구 결과, '아, 에, 이'의 F2/F1의 그래프가, B4(493.8Hz)이상의 F0에서는 거의 직선으로 나타났다. B4는 Changing Voice가 시작되는 곳으로, 성악가의 음색 변화가 포르만트 형태의 변화와 밀접한 관계가 있음을 알 수 있다. 또한, A5에서는 '아, 에, 이, 오, 우'의 F1, F2의 수치가 거의 일치하는 것으로 나타났다. 즉, 최고음부에서 불려지는 모음들은 서로 구별되기가 어렵게 되는 것이다. 본 논문은 성악발성 평가 시스템이나 성악발성 합성 시스템을 구축할 때에, '아, 오, 우'의 경우에는 B4에서 A5의 F1, F2를 F0대한 기울기로 규정화할 것을 제안한다. 이와 같은 규정화를 통하여 성악발성과 관련된 시스템 구축에 필요한 노력과 비용을 줄일 수 있을 것이다.
