Functional dyspepsia is one of the most common bowel disorders as prevalent of 7.7% Korean population. The cardinal manifestations include bothersome postprandial fullness, early satiation, epigastric burning or pain. These features are chronic and should be presented recurrently with no other compatible organic disease to explain the symptoms. Even though it is not life-shortening, functional dyspepsia usually make the health-related quality of life worse especially if other functional bowel disorder coexist. The coexistence of functional bowel disorders is called as 'overlap syndrome'. Anxiety, somatization and insomnia is more prevalent in overlap syndrome compared with sole functional bowel disorder. Therefore, it is worthwhile that physician interviews and elucidates whether the dyspeptic patient had other kinds of functional bowel disorders, and manages the underlying psychotic pathology. Placebo effect is large in functional dyspepsia, and there is only four kinds of prokinetics that is proven to be superior to placebo. Adverse events relating prolonged administration of prokinetics sometimes fatal or irreversible, physician willing to describe prokinetics should be familiar to the possible adverse effects and the relating risk factors. Pathologic acid reflux is not uncommon in functional dyspepsia, and acid-suppressant is equivalent to the prokientics in most of dyspeptic patients.

복통은 말 그대로 '배가 아픈 것'을 말하며, 한 번쯤 겪어보지 않은 사람이 없을 만큼 흔한 증상이다. 복통은 흔한 만큼 그 원인도 다양하다. 소화불량, 역류성 식도염, 과민성 대장증후군, 간염, 위궤양 등 비교적 널리 알려진 질병도 있지만 크론병, 게실염 등 일반에게는 생소한 질병도 있다.

In order to determine optimum condition for the Ko-Choo-Jang (red-pepper-paste) processing, chemical analysis, mixed ratio, and sensory teat, resulted as follows. 1. The best nutritional value could be obtained after three hours at $60^{\circ}C$, which proved to be the optimum temperature in koji digestion of starch paste. 2. The component ratio of wheat flour to koji-powder was two to one giving the best digestion. 3. The mixing ratio of salt and red-pepper-powder and flour-koji was determined as 1 : 1.5 : 3 by sensory tests. 4. The highest reducing sugar content appeared in a digested mixture using glutinous rice as a starch source and the reducing sugar increased continuously with decreasing, total sugar content in almost every mixture of starches. 5. As a starch source, glutinous rice powder produced the highest total sugar in the beginning stages, however, after 10 day's curing produced less sugar than rice powder. 6. The order of total nitrogen content in the cured paste was recorded as wheat-flour, rice-powder, corn-powder, glutinous-powder, barley-powder, and sweet potato-starch. 7. Amino-nitrogen was increased with curing and the highest, value was observed in the case of wheat flour. 8. In sensory test, Ko-Choo-Jang made of glutinous rice-powder resulted in the best taste.

Intestinal tuberculosis is an infection of the gastrointestinal tract by the Mycobacterium tuberculosis complex. To the best of our knowledge, solitary intestinal tuberculosis accompanied by intestinal obstruction, particularly in the middle of the small intestine, is extremely rare. We report a case of solitary jejunal tuberculosis in a 49-year-old man with no underlying disease. He was admitted a few days after the onset of diffuse abdominal discomfort. Upon evaluation, we initially considered a malignancy of the distal jejunum with ileus due to the presence of a mass. Therefore, he underwent laparoscopic resection of the small bowel. Unexpectedly, the histologic specimen showed a chronic caseating granulomatous lesion with acid-fast bacilli. Ultimately, he was diagnosed with solitary jejunal tuberculosis. He was successfully treated with anti-tuberculosis drugs without any complications.

Indoor hydrant facilities are used to fight initial fires before more intense fire extinguishing activities. Fire extinguishing facilities should ensure good fire extinguishing performance and the safety of users. Indoor hydrant facilities are mostly installed in buildings and facilities, and users must manipulate valves, hoses, and nozzles manually. When the discharge pressure is higher than 0.70 MPa, there is a high possibility that problems with manipulation and hose breakdown can occur. To prevent these problems, a method to attach orifice-type decompression valves to the angle valves of indoor hydrant discharge outlets has frequently been used for decompression methods. However, the decompression performance was reduced due to structural problems of the decompression valves over time. Accordingly, based on three-stage initial pressures, applicable pressure ranges were selected by measuring the decompression performance according to the diameter of the decompression orifices. Based on the data, stable decompression valve models are proposed. These models have the lowest decrease in decompression performance, regardless of time.

This study describes extinguishment mechanism of the purely buoyant diffusion flame using the water spray. Experiments are systematically carried out for the oul pool fire with the six different atomizing nozzles. From the measurement of burning rate which represents the combustion intensity of fire, it is observed that the water spray is able to act to enhance fire rather than to extinguish fire. The air entertainment due to the water spray is visualized to understand this phenomenon, acting to enhance fire. In order to observe effects of droplet size on fire extinguishment, and amount of water which reaches the flame base, fuel surface, and mean diameter of droplets are measured. When water droplets are too small, they do not reach the flame base because they can the water spray having too small doplets is ineffective for extinguishment of the oil fire.

It is already known that adzuki beans (Vigna angularis) are able to control appetite. Therefore, this study tested the proteins isolated from adzuki beans for their protease resistance and interaction with the intestinal mucosa. The major proteins from adzuki beans were found to be resistant to the digestive enzymes pepsin and pancreatin, and were identified using 2D-SDS-polyacrylamide gel electrophoresis and mass spectrometry. The major adzuki proteins were easily fractionated by treating the soluble protein extract with 10mM $CaCl_2$, and were found to contain lactotransferrin, a homologous protein to the dynein light chain domain, proteinase inhibitor, and proteins with unknown functions. From a tissue binding assay using mouse intestinal tissue sections, the major protein fraction showed weak, yet significant and specific binding to the mucosa layer of the small intestine. Thus, the current results suggest that adzuki proteins are resistant to digestive enzymes, which enables them to survive protease digestion in the intestinal tract, plus they may interact with the intestinal mucosa layer. Therefore, the molecules responsible for controlling appetite in adzuki beans are presumably protease-resistant proteins that interact with the intestinal mucosa or delay digestion in the digestive tract.

Acid phosphatase(AP) of he aphid, Megoura crassicauda and the major component of the lady beetle's artificial diet, fresh chicken liver, was adapted as a model protein to study the digestion of diet proteins in the midgut of Harmonia axyridis. The lady beetle did not secrete its own AP into the lumen of the midgut. The aphid and the live chicken liver had AP which was still alive in enzymatic activity from the extract of the lumen of the midgut of the lady beetle. The digestive ability of the lady beetle on proteins turned out to be different depending on food sources. In the lumen of the midgut of the lady beetle, though most of AP of live chicken liver lost its activity withtin 12 hours, that of M. cassicauda kept strong enzymatic activity up to 24 hours.

The genus Pseudostellaria (Caryophyllaceae) in Korea was investigated in order to clarify the taxonomic positions and scientific names among the species in this genus based on morphological characteristics. P. ${\times}$ bohyeonsanensis and P. ${\times}$ seoraksanensis share several characteristics (trichome on the sepal margin and midvein, five petals, and stem reclining to the ground after flowering) with P. davidii. P. ${\times}$ bohyeonsanensis, resulting from natural hybridization of P. davidii and P. okamotoi var. longipedicellata, has sterile fruit and a long pedicel (2.2-6.0 cm). P. ${\times}$ seoraksanensis, a natural hybrid of P. davidii and P. palibiniana var. palibiniana, has sterile fruit and a short pedicel (1.1-1.8 cm). P. okamotoi var. longipedicellata shares several characteristics (long pedicels of chasmogamic flowers that elongate to the ground when bearing fruit and cleistogamic flowers with a long pedicel) with the related taxa P. okamotoi var. okamotoi. P. okamotoi var. longipedicellata has slender root tubers, glabrous pedicels, and 5-9 petals. P. palibiniana var. gageodoensis is described from Gageodo Island. It is similar to P. palibiniana var. palibiniana having chasmogamic flowers at the stem terminal, 5-7 petals, and a short pedicel, but P. palibiniana var. gageodoensis is distinguished by 1-2 rows of trichomes on the pedicel, a large sepal size, a large petal size, and a branched stem at its base. P. ${\times}$ biseulsanensis, from a natural hybrid of P. heterophylla and P. okamotoi var. longipedicellata, has a solitary aerial stem, a chasmogamic flower at the stem terminal, a shallow marginate or bitten petal apex, one row of trichomes on the pedicel, and sterile fruit. P. ${\times}$ segeolsanensis, from a natural hybrid of P. palibiniana var. palibiniana and P. okamotoi var. okamotoi, is described from Segeolsan Mt. It has numerous aerial stems, a chasmogamic flower at the stem terminal, 1-2 rows of trichomes on the pedicel, and fertile fruit. Consequently, the genus Pseudostellaria in Korea has been classified into eight species, four hybrids, two varieties, and five forms.
