To investigate the nature of artifacts caused by air and chemical shift by fat, a test tube phantom study was performed in 2.0T and 0.5T superconducting magnetic resonance imaging systems in various imaging sequences. Spatial mismapping and signal change made image distortion in spin echo images of the air-column and severe signal voids in gradient echo images. Chemical shift artifacts appeared in the planes of frequency-encoding axis as crescent-shaped signal voids and summated bright signals, Both artifacts were more prominent in high field strength, Images at 0.5T showed more severe artifacts in the T2-weighted images than those in the other sequences. As the acquisition matrix increased, truncation artifacts decreased and susceptibility artifacts in gradient echo images diminished. Familiarity with causes, appearances and mechanisms of various artifacts will help radiologists for interpretation of MRI.

The purpose of this study was to compare the status of sanitation education and sanitation knowledge in school foodservice with commercial foodservice. The survey sample was institutional foodservice directors (n = 88) in A office of education and commercial foodservice directors (n = 81) in B foodservice industry. The questionnaire requested information about demographic information, situation of sanitation education, contents of sanitation education practice, importance of sanitation education, and sanitation knowledge. Data were analyzed using frequencies, means, chi-square test, and t-test. Over half (52.1%) of the respondents were institutional foodservice directors, 47.9% of the respondents were commercial foodservice directors. The majority of institutional foodservice directors were 25-29 years of age (38.6%), over 10 years of working experience (63.6%) and commercial foodservice directors were 25-29 years of age (53.1%), 5-10 years of working experience (35.0%). 66.3% of the respondents were educated food safety once a month, but 8.6% of commercial foodservices were never educated. The majority of the respondents used printing materials (73.3%) or lecture (74.8%). The importance level of institutional foodservice directors about sanitation education was significantly higher than commercial foodservice directors. The average score of institutional foodservice directors'sanitation knowledge was 87.05/100.00. The commercial foodservice directors'sanitation knowledge 67.74 was significantly lower than institutional foodservice directors (p< 0.05). Therefore, there should be a systematic education program designed for commercial foodservice directors.

One adverse effect of PUVA therapy is the development of severe dermatitis. Only a few cases of photoallergy to psoralens during PUVA therapy have been reported. We describe herein a patient with photoallergic dermatitis induced by PUVA with 8-methoxypsoralen(8-MOP). A 38-year old woman with generalized vitiligo had acute pruritic exanthematous maculopapular lesions in the treated areas after PUVA therapy with 8-MOP. A patch test and photopatch test were performed with 8-MOP, 5-MOP, and 4,5,8-trimethylpsoralen(TMP). The patch test carried out with these psoralen derivatives were all negative, but the photopatch test showed a positive reaction to 8-MOP. The patient consequently had PUVA therapy with 5-MOP and she had no further experience of a photoallergic reaction.

Midtrimester genetic amniocentesis has been a gold standard for prenatal diagnosis in antenatal care since last 25 years. After the triple serum marker test was introduced as a prenatal screening method for Down syndrome, the frequency of genetic amniocentesis was increased. OBJECTIVE: To determine the complication, risk of amniocentesis and detection rate of chromosomal abnormality. MATERIAL AND METHODS: A retrospective clinical analysis of 1,064 midtrimester genetic amnicentesis in IL Sin Christian Hospital antenatal clinic from Jan 1995 to Dec 1997. Chi square test was used for the statistical analysis and p value < 0.05 was considered significant. RESULTS: Amnicentesis were significantly increased in the age of 35-39 yrs and 40yrs over. And also the incidence of chromosomal abnormality was higher than younger age group. The indications of amnicentesis were screen positive of triple marker test(43%), advanced maternal age(20.8%), abnormal beta-hCG level, past history of chromosome abnormality or malformed baby and abnormal alpha-FP level in order. Total number of chromosomal abnormalities was 30 and the incidence of chromosomal abnormalities was 2.8%(30/1,064). The complications were developed in 13 cases and fetal loss rate was 0.78%(9/1,064). CONCLUSION: The detection rate of chromosomal abnormality in midtrimester amnicentesis for prenatal diagnosis was high and relatively safe procedure but, we should be attention to more careful manipulation.

A wide variety of cancers metastasize to the ovaries. In a majority of instances the primary site is the gastrointestinal tract, breast, or other gynecologic organs. The best known tumor of this type is signet-ring cell adenocarcinoma. The gallbladder and bile duct are rare sources of these metastases. The authors have had an experience of a case that was presented of Krukenberg tumor metastatic from the gallbladder and report the case with brief review of literature.

Acquired port-wine stain is rare. It mimics a congenital port-wine stain morphologically but the pattern of onset is acquired after birth. It represents a progressive ectasia of vessels located in the superficial vascular plexus. The exact mechanism is unknown but some reported cases have occurred after trauma. We herein report five cases of acquired port-wine stains and they were idiopathic in nature.
