As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrent further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

Purpose: In maxillofacial surgery, proper preoperative diagnosis is very important in achieving good postoperative results. Although conventional CT scans are useful for visual representations of fractures, they cannot provide direct guidance for reconstructing facial bone fractures. However, the recent technology of multislice scanning has brought many clinical benefits to CT images. Direct correlations can be made between preoperative imaging data and operative planning. The aim of the current study is to evaluate the differences between conventional CT and multidetective three-dimensional CT(3D MDCT) measurements in craniofacial deformities. Methods: From January 2005 to November 2005, MDCT scans of 41 patients were evaluated by comparing them with conventional CT scans. The 3D MDCT images were assessed and reviewed by using a simple scoring system. Results: The 3D MDCT scans offered easy interpretation, facilitated surgical planning, and clarified postoperative results in malar complex fractures, mandibular fractures, and extensive maxillofacial fractures and cranioplasty. However, 3D MDCT images were not superior to conventional CT scans in the diagnosis of blowout fractures. Conclusion: In spite of its limitations, the 3D MDCT provided additional and more comprehensive information than the conventional CT for preoperative assessment of craniofacial deformities. Therefore, the 3D MDCT can be a useful tool for diagnosis and systematic treatment planning in craniofacial skeletal deformities.

The importance of emergency diesel generator(EDG) has confirmed in the safety evaluation of PSA and the study on aging of EDG has been progressed actively as a part of the project of nuclear plant aging research in the U.S.A. As the result, the concept of performance evaluation is being transferred from statistical analysis of test results to performance monitoring and trending analysis for monitoring of aging and reliability. Recently, the study related aging characteristic and reliability for EDGS has begun in Korea. Consequently, the efficient performance monitoring based systematic and integrated monitoring and failure diagnostic technology is necessary. In the research, the knowledge basis of monitoring parameters for EDGS is constructed, and the prototype monitoring and diagnosis system applicable to Pielstick EDG is developed.

The Korean occurrence of Holopyga generosa (F$\ddot{o}$rster, 1853) is reported here for the first time. The genus is also new to Korea. This species might be easily distinguished from other Holopyga species by its relatively long hairs on the head and mesosoma. Diagnosis and digital images are provided.

We report three newly recorded campoplegine species, Klutiana jezoensis (Uchida, 1957), Dusona maruyamator Hinz, 1979, Dusona petiolator (Fabricius, 1804), for the first time from Korea. Genus Klutiana Betrem (1933), is firstly recorded from Korea. Photographs and diagnosis are provided for identification.

Foreign bodies of the upper aerodigestive tract in the pediatric population are a common occurrence. However, despite significant advances in prevention, first aid and endoscopic technology, they remain a diagnostic and therapeutic challenge. Early diagnosis is the key to successful and uncomplicated management of these accidents. An orderly and systematic approach to these patients including a careful history, physical exam and radiographic studies is detailed in this review.

In this paper, we report for the first time on a species of Eupithecia from Korea. Three females of Eupithecia praepupillata Wehrli, 1927, were collected from the northeastern part of South Korea. With this addition, a total of 53 species of Eupithecia from Korea have been recorded. Diagnosis and description of the species are provided with figures of the genitalia.

We report a larentiine species, Collix stellata Warren, for the first time from Korea. Two males and one female were collected from Jeju-do Island, South Korea. Collix stellata is similar to Collix ghosa Walker in external appearances, but can be distinguished by the relatively larger discal dot on forewing and the relatively slender valva with distally projected margin of male genitalia. Diagnosis and description of the species are given with the figures of the genitalia.
