This investigation was conducted to evaluate the shrimp flesh (SF) and shrimp by-product (SB) of the most abundant shrimp species (Metapenaeus affinis, Penaeus semisulcatus and Penaeus monodon) caught in Central Vietnam, with the emphasis on yield, gross and amino acid (AA) composition and effect of heat treatment. The results showed that the mean edible SF and SB (head and shells with tail) yields of the three shrimp species averaged 56.7 and 43.3%, respectively, of the total wet body weight, with the M. affinis generating the highest by-product yield (45.7%) and P. semisulcatus (40.6%) the lowest. Significant differences in dry matter (DM), crude protein (CP) and ash content were found between SF and SB. The DM content of SF (21.5%) was lower than of SB (24.9%) and the ash content (on a DM basis) of the SB in all shrimp species was more than three times that of the SF (p<0.05), whereas the CP content was almost twice as high in the SF as compared with the SB (p<0.05). The SB of the three species contained (on a DM basis) between 44.0 and 49.8% CP (p<0.05) and between 13.5 and 18.1% chitin (p<0.05). The Ca content of SB differed also between species (p<0.05). On average, the sum of AA in SB corresponded to 89.3% of the CP and essential AA accounted for about 50% of the total AA. The most abundant AA were arginine, aspartic and glutamic acids, which accounted for 33% of the total AA. Minor, but significant differences in some AA concentrations of SB between species were observed (p<0.05). With the exception of the DM and ether extract content, all other chemical constituents of entire shrimp, SF and SB were not significantly affected by heat treatment (p>0.05).

The primary sound produced by the vibration of vocal folds reaches the velopharyngeal isthmus and is directed both nasally and orally. The proportions of the each component is determined by the anatomical and functional status of the soft palate. The oral sounds composed of oral vowels and consonants according to the status of vocal tract, tongue, palate and lips. The nasal sounds composed of nasal consonants and nasal vowels, and further modified according to the status of the nasal airway, so anatomical abnormalities in the nasal cavity will influence nasal sound. The measurement of nasal sounds of speech has relied on the subjective scoring by listeners. The nasal sounds are described with nasality and nasalization. Generally, nasality has been assessed perceptually in the effect of maxillofacial procedures for cleft palate, sleep apnea, snoring and nasal disorders. The nasalization is considered as an acoustic phenomenon. Snoring and sleep apnea is a typical disorders due to abundant velopharynx. The sleep apnea has been known as a cessation of breathing for at least 10 seconds during sleep. Several medical and surgical methods for treating sleep apnea have been attempted. The uvulopalatopharyngoplasty(UPPP) involves removal of 1.0 to 3.0 cm of soft palate tissue with removal of redundant oropharyngeal mucosa and lateral tissue from the anterior and sometimes posterior faucial pillars. This procedure results in a shortened soft palate and a possible risk following this surgery may be velopharyngeal malfunctioning due to the shortened palate. Few researchers have systematically studied the effects of this surgery as it relates to speech production. Some changes in the voice quality such as resonance (nasality), articulation, and phonation have been reported. In view of the conflicting reports discussed, there remains some uncertainty about the speech status in patients following the snoring and sleep apnea surgery. The study was conducted in two phases: 1) acoustic analysis of oral and nasal sounds, and 2) evaluation of nasality.

A comparison between the body types of Korean and Mongolian women was made and analyzed to provide a foundation for securing the Mongolian fashion market. 404 adults within the 18 to 24 age group were studied. From the results of comparing 27 items of direct anthropometric measurements, 15 items were shown to have significant differences. Mongolian women were larger in values for 13 items than were Korean women except two items, which are back waist length and arm length. From the results of comparing 25 items of index values, 19 items were shown to have significant differences. The comparison of the anatomical proportions showed that the lower half of Mongolian women's bodies were longer and their shoulder and hips were wider than those of Korean women. Based on these direct anthropometric measurements and index values, Korean and Mongolian women were categorized into 4 Types; Type 1 is average body type with tall height and longer lower half of the body. Type 2 is slimmer body type with average height. Type 3 is average body type with shorter height. Lastly, type 4 is obese body type with average height.

Rabbit meat has high nutritional and dietetic characteristics, but its consumption rate is comparatively lower than other meat types. The nutritional profile of rabbit meat, by comparison with beef, pork, and poultry, is attributed to relatively higher proportions of n-3 fatty acids and low amounts of intramuscular fat, cholesterol, and sodium, indicating its consumption may provide health benefits to consumers. But, the quality attributes of rabbit meat can be originated from different factors such as genetics, environment, diet, rearing system, pre-, peri-, and post-slaughter conditions, and others. Different rabbit breeds and the anatomical location of muscles may also affect the nutritional profile and physicochemical properties of rabbit meat. However, adequate information about the effect of those two factors on rabbit meat is limited. Therefore, cumulative information on nutritional composition and carcass and meat quality attributes of rabbit meat in terms of different breeds and muscle types and associated factors is more important for the production and processing of rabbits. Moreover, some studies reported that rabbit meat proteins exhibited angiotensin-converting enzyme inhibitory characteristics and antioxidant properties. The aim of this review is to elucidate the determinants of rabbit meat quality of different breeds and its influencing factors. In addition, the proven biological activities of rabbit meat are introduced to ensure consumer satisfaction.

Ovaries from total 192 slaughtered cows(154 Korean native cows and 38 Holstein cows) were collected during the slaughtering process in Kimhae, Changyoung and Yangsan abattoirs in Kyungnam province from January 2001 to January 2002. In order to investigate incidence of the ovarian cysts, anatomical, histological observations were performed and also TUNEL methods and PCNA antibody by immunogistochemical methods for diagnostic accuracy of cysts in a few ovaries were applied. Apoptotic positive cells by TUNEL method appeared not or a few in cystic walls but appeared more number in normal large follicular walls and the proliferative positive cells by PCNA antibody appeared numerous in normal large follicular walls but not or a few in cystic walls. The incident rates of ovarian cysts were 19.5% in Korean native cows and 18.4% in Holstein cows. The incident rates of ovarian cysts in Holstein cows were lower than that of Koran native cows. The incident rates of follicular cysts and luteal cysts in Korean native cows were 11.7% and 7.8% respectively. The incident rates of follicular cysts and luteal cysts in Holstein cows were 10.5% and 7.9%, respectively. Higher incidence proportions of ovarian cysts according to seasons in Korean native cows were ordered as spring (29.8%), autumn (21.4%) winter (14.3%) and summer (6.7%). Rates of cows with single cyst and multiple cysts were 63.3%(19 heads /30 heads) and 36.7%(11 heads/30 heads) in 30 cystic Korean native cows, respectively. Cystic cows with corpus luteums were 50.0%(15 heads) in 30 Korean native cows and 42.9%(3 heads) in 7 dairy cows, respectively. Among 15 cystic Korean native cows with corpus luteums, rates of cows with single corpus luteum were 66.7%(10 heads) and rates of multiple corpus luteum were 33.3%(5 heads ), respectively. The average diameter of cysts and corpus luteums in cystic ovaries were 21.0$\times$17.1 mm and 18.1$\times$13.8 mm in 30 Korean native cows and 20.6$\times$17.7 mm and 19.3 $\times$ 14.9 mm in 7 Holstein cows, respectively. So the average sizes of cysts in cystic ovaries were larger than those of corpus luteums.

단감(Diospyros kaki) 저장시 문제되는 과정부 갈변은 품종마다 다른 양상을 보이고 있다. 따라서 본 연구는 단감품종의 일반적인 과실의 물성특성을 파악하고, 저장 100일 후에 각 품종의 과육갈변이 세포구조에 어떠한 영향을 미치는 지에 대해서 조사하였다. 단감 품종은 '부유'(Fuyu), '차랑'(Jiro), '상서조생'(Uenishiwase), '대안단감'(Daiandangam), '로-19'(Ro-19)이며 2003년 10월말에 수확해서 저장 100일 후에 조사하였다. 과실의 각 물성의 특성은 품종마다 다양하였고, '차랑'과 '로-19'는 갈변과가 관찰되지 않았고, '대안단감'의 경우 80%에 가까운 과육 갈변과가 나타났다. 과육 갈변과 발생이 많은 품종인 '부유', '상서조생', '대안단감'과, 과육 갈변과가 발생하지 않는 '차랑' 및 '로-19'와의 과피구조에는 차이가 없는 것으로 조사되었다. '차랑'은 과피층이 외표피층을 포함하여 1~2층으로 형성되어서 갈변이 유도될 만한 세포층 자체를 형성하지 못하는 것으로 보이며, '부유'는 과피층이 2~3층으로 갈변이 유도될 만한 세포층을 제공한 것으로 판단된다. 정상과와 갈변과의 전체적인 조직의 구조적인 차이는 발견되지 못하였으나, 갈변과의 경우 과육 내 소포 소기관이 구별이 되지 못했고, 세포벽의 분해가 진행되는 것으로 관찰되었다.
