A layer feeding trial was conducted for 10 weeks to investigate the effects of the addition of corn distillers dried grains with solubles (DDGS) to layer diets on the laying performance, egg qualities, and yolk fatty acid composition. Nine hundred Hyline Brown layers, 24 weeks of age, were randomly allotted to 20 replicate laying cages, 45 birds per replicate. There were four diet treatments (0, 10, 15, and 20% DDGS), and five replicates per treatment. All experimental diets were prepared to contain iso-protein (17%) and iso-calorie (TMEn 2,780 kcal/kg). The use of DDGS up to 20% level in layer diets did not exert any influence on feed intake, laying rate, total egg mass, mean egg weight, and feed conversion ratio. DDGS did not exert any influence in weight of egg, breaking strength, and color of eggshell. The albumen height and Haugh unit was not influenced by DDGS addition. The yolk color was significantly increased by DDGS supplementation. As the DDGS level increased, the oleic acid content decreased, and the linoleic acid increased (P<0.05). The degree of saturation of yolk fatty acids was not affected by dietary DDGS. The inclusion of DDGS up to 20% in layer diets resulted in the decrease of feed cost per kg without any effect in the laying performance. In conclusion, the use of DDGS up to 20% level in layer diets could replace corn and soybean meal without any harmful effect on the laying performances.

Gastric candidiasis is an uncommon disorder. It is an opportunistic pathogen in immune compromised individuals, alcoholics, persons treated with broad-spectrum antibiotics, immunosuppressive and chemotherapeutic agents. Besides, the use of drugs that reduce the gastric acid production may be a cause of gastric candidiasis. We experienced a case of gastric candidiasis following advanced gastric adenocarcinoma. A 85-year-old woman was admitted to our hospital because of epigastric soreness. Endoscopic findings revealed a large ulcero-infiltrating mass with yellow exudate at cardia of the stomach, which suggested an advanced gastric cancer. Endoscopic biopsy revealed spores and pseudohyphae infiltrating through the ulcerated stomach wall, diffuse infiltration of tumor cells and abortive tumor glands. After treatment with fluconazole 100 mg daily for 21 days, no evidence of the gastric candidiasis was seen on endoscopic biopsy and pathologic findings. The case is herein reported of gastric candidiasis following advanced gastric adenocarcinoma along with a review of corresponding literature.

1) According to Article 747(Limits of Liability) para. 1 of the Korean Commercial Act, the limit of the liability for claims against the shipowner shall be calculated as follows : 1. The limits of the liability in respect of claims for loss of life or personal injury of passengers shall be an amount of 46,666 Units of Account multiplied by the number of passengers which the ship is authorized to carry according to the ship`s certificate, but not exceeding 25 million Units of Account. Article 747 paragraph 1 adopted Article 7 (The limits for passenger claims) of International Convention on Limitation of Liability for Maritime Claims, 1976. Article 750 (Persons Entitled to Limit Liability) paragraph 1 of the Korean Commercial Act provides that charterer, manager and operator of a ship may limit their liability to the same extent as the shipowner in accordance with the provisions of the Chapter. 2) The provision of Article 7 of the Convention on Limitation of Liability for Maritime Claims, 1976 was amended by the Protocol of 1996 ; The limit of liability of the shipowner was raised to an amount of 175,000 Units of Account multiplied by the number of passengers (the limit of 25 million Units of Account was deleted). Accordingly Article 747 paragraph 1 of the Korean Commercial Act (the limit of the liability for claims against the shipowner) should be considered increasing the above-men tioned limits. 3) According to Korean Commercial Act, a carrier shall not be relieved of liability for damages from any injury sustained by a passenger arising from the carriage unless the carrier proves that neither he nor any of his employees has neglected care in connection with the carriage( Art. 148 para. 1, Art. 830 para. 1). The Act does not limit the liability of the carrier for the damage sustained by a particular passenger carried by sea. Athens Convention relating to the Carriage of Passengers and Their Luggage by Sea, 1974 and Protocol of 1990 to amend the Athens Convention, 1974 ought to be considered to be adopted into the liability of the carrier by sea in the Act.

In vasospastic angina, exercise typically does not lead to vasoconstriction. We present the case of a patient with an atypical presentation of vasospastic angina, characterized by regional wall motion abnormalities confirmed by exercise stress echocardiography. A 58-year-old female patient presented to the hospital reporting chest pain during both exercise. During the exercise stress echocardiogram, regional wall motion abnormality was confirmed. However, the coronary angiography did not reveal significant lesions. Subsequently, ergonovine test was positive and then exercise induced vasospastic angina was diagnosed. Following medical treatment, the patient’s symptoms showed improvement. This case underscores an uncommon presentation of vasospastic angina in an individual already diagnosed with coronary artery disease, indicating that exercise stress echocardiography could serve as a valuable screening tool for specific types of vasospastic angina.

A CMOS RF bandpass amplifier which performs both functions of low-noise amplifier and bandpass filter is designed for the application of 900 ㎒ RF front-end in wireless receivers. The positive-feedback Q-enhancement technique is used to overcome the low gain and low Q factor of the bandpass amplifier. The Miller-capacitance tuning scheme compensates for the process variations of center frequency. The designed bandpass amplifier is simulated with HSPICE and fabricated using 0.8 ㎛ CMOS 2-poly 2-metal full custom process. Under 3 V supply voltage, results of simulation show that the CMOS bandpass amplifier provides the quality factor Q of 40 and the gain of 20 ㏈. The center-frequency tuning range is from 894 ㎒ to 906 ㎒ and power dissipation is about 72 ㎽.
