This research has a purpose to help academic high school students to choose their own career by developing an examination that distinguishes between liberal arts and natural sciences. Besides an aptitude test, I identified the necessity of a tool for distinguishing liberal arts and natural sciences, using an examination tool that uses puzzles to distinguish liberal arts and natural sciences and conducted the first examination. On the basis of the result of the first examination I made the second examination test, and the algorithm. After conducting the second examination to a variety of target subjects, like academic high school students, university students, and graduate students through the second examination paper and algorithm for distinguishing liberal arts and natural sciences, competent results have been deducted.

Three dogs referred to Veterinary Medical Teaching Hospital, Seoul National University were diagnosed as intervertebral disc disease. Physical examination, neurologic examination, survey radiograph, and myelography were performed in patients. Case 1 showed narrowing intervertebral space and calcified intervertebral disc material in survey radiograph. Case 2 showed increased opacity in the intervertebral opacity in survey radiograph. All of 3 cases showed extradural pattern during myelography. In survey radiography, radiographic signs consistent with intervertebral disc herniations include narrowing of the disc space and the dorsal intervertebral articular process joint space, small intervertebral foramen, increase opacity in the intervertebral foramen and extruded, mineralized disc material within the vertebral canal. Myelography is useful for evaluating the spinal cord and the cauda equina. Indication for myelography includes confirming a spinal lesion seen or suspected on survey radiograph, defining the extent of a survey lesion, finding a lesion not observed on survey radiograph, and distinguishing between surgical and nonsurgical lesion. In presentcases, two of three cases show radiographic signs of IVDD with survey radiograph and all of three case show extradural pattern during myelography. It is observed that intervertebral disc disease is one of the most important indication for radiographic examination and myelography of the vertebral column of small animals.

Purpose: The purpose of this study was to describe the essential structure of the postmortem- examination experiences of nurse career coroners (forensic investigators), to have a profound understanding of their experiences, and ultimately to lay the foundation for nurses' entry into the field of forensic nursing. Methods: The subjects in this study were six coroners. After an in-depth interview from January to June 2007, the collected data were analyzed by Colaizzi as qualitative research. Results: Four categories emerged from seven theme clusters. The four categories were: attracted by being dubbed a stabilized public official, a sense of achievement due to having clarified false death, self-confidence after distinguishing the victim and the wrongdoer, eternal developmental potential is seen. Conclusion: It is expected that this study will provide useful information for nurses who are interested in becoming coroners. It will be helpful for career nurses to extend their nursing science into emerging fields like coroners and select a follow-up career.

Nodular thyroid disease is a common clinical problem. The problem in clinical practice is to distinguish malignant or potentially malignant tumor from harmless nodules. The cases of thyroid nodule surgically managed at Department of General Surgery, Soon Chun Hyang Univ. Hospital during the period Jan. 1985 to July. 1992 were reviewed retrospectively. To assess method of distinguishing malignant from benign lesions of the thyroid gland, we reviewed 162 patients with thyroid nodule. There were 61(37.7%) malignant nodules and 101(62.3%) benign nodules. According to the review, distinguishing the benign from the malignant nodule with history, physical examination, clinical manifestation, and duration of illness was not suggested sufficiently. In ultrasonogram of 73 cases, 57.5% of nodules were solid, 20.6% were cystic, 21.9% were mixed solid and cystic. Of these, 28.5% of the operated solid lesions, 12.5% of the mixed lesions, and only 6.7% of the cystic lesions were malignant. Thyroid scanning of 82 cases revealed cold nodules in 60 patients(73.2%), of which 26 cases were malignant(36.6%) 137 patients underwent fine needle aspiration cytology(FNAC), and these results were as follow: sensitiviey was 70.6%, specificity was 93.0%, false-positive rate was 14.3%, and false-negative rate was 15.8%. 41 patients underwent frozen biopsy, and the results as follow: sensitivity was 80.0%, specificity was 89.7%. Neither scintigraphy nor ultrasonogram has sufficient specificity to distinguish benign from malignant nodule. But FNAC and frozen biopsy have sufficient accuracy to differentiate benign from malignant nodule. In the benign nodules, the most common type of operation was total lobectomy (60.4%). Of the malignant nodules, total thyroidectomy with or without modified radical neck dissection was performed in 30 cases(49.2%). We conclude that the single technique used to determine the differential diagnosis of a thyroid nodule are unrealiable. It is therefore essential to combine all avaiable clinical and laboratory information.

Background and Objectives : Aerodynamic analysis is an examination which provides information regarding various vocalization measures indicating laryngeal efficiency. Voice evaluation using such examination must be capable of distinguishing between normal to abnormal voice. It also observes variables on aerodynamic characteristics by gender in regards to patients of vocal disorders, especially of vocal cord paralysis and vocal polyp, and compares the conditions before and after surgery. This paper therefore, seeks to build a framework for establishing standard levels of aerodynamical characteristic on vocal disorders. Subjects and Methods : The study was intended for a total number of 20 patients with vocal polyp or unilateral vocal cord paralysis. Those with the vocal polyp underwent laryngomycroscopy surgery and the vocal cord paralysis, vocal fold injection using Restylane. Aerodynamic analysis fulfilled the Maximum sustained Phonation (MXPH) and Voicing Efficiency (VOEF) by using PAS Model 6600 (KayPENTAX, USA). Results : In MXPH, increase in PHOT were evident with vocal polyp after surgery. As for patients with vocal cord paralysis, MAXDB, MEADB, DHODB, PHOT all have increased and MEAP, PEF, MEAF decreased after surgery. In VOEF, patients with vocal cord paralysis who underwent surgery showed increase in MAXDB, MEADB, DHODB, FET100, ARES, but decreases in PEF, TARF. Conclusion : Overall, it can be concluded that patients with the vocal polyp and vocal cord paralysis seemed to get closer to the normal values after than before surgery in majority of measures. This confirms that the function of their vocal cord has improved nearly to normality through operations.

Osteopoikilosis is a rare, benign hereditary disease, which presents multiple osteosclerotic, and small round nodules in the bone. It is usually detected incidentally by radiological examination. A radionuclide bone scintigraphy is essential in distinguishing osteopoikilosis from osteoblastic metastases, because scintigraphic findings are usually normal in patients with osteopoikilosis. However, there have been no reports about F-18 fluorodeoxyglucose (FDG) PET findings in osteopoikilosis. Herein, we wish to report a case of osteopoikilosis with breast cancer, which could not be seen in either bone scintigraphy or F-18 FDG PET/CT.

Using imprint cultures and epithelial smears, the density and prevalence of colonization of oral mucosal sites and denture surfaces by Candida albicans has been determined in 28 healthy dentate subjects and 20 denture wearers. With questionnaire, oral and denture examination, the relationship between the carrier rates and several factors; DMFT, oral hygiene index, salivary pH & denture plaque score were studied. But these factors have not significant relationship to the carrier rates. Imprint culture appears to be sensitive technique for detecting candidal carriers and be useful for distinguishing between the healthy carrier state and candidal infection. Cigarette smokers had a significantly increased carrier state (P<0.05) compared with nonsmoker in male dentate subjects. Female were more frequent carriers than male in dentate and denture group, but these differences were not significant. In denture wearers, there was a higher density and frequency of candidal colonization of all mucosal sites sampled, compared with that of healthy dentate group especially anterior palate and posterior palate showed highly significant differences in frequency of candidal colonization (P<0.05). The distribution of Candida albicans is not uniform throughout the mouth. The tongue in the healthy dentate subjects and the impression surfaces of upper dentures are the primary oral reservoirs for the fungus. Overnight wearing of dentures was associated with increased density and frequency of candidal colonization and density.

Trichoblastic carcinoma usually occurs as a malignant transformation of the trichoblastoma, but is very rare. A 25-year-old man was admitted with trichoblastoma in the nuchal area with frequent recurrences since birth. The preoperative neck magnetic resonance image revealed lobulated soft tissue lesions involving superficial fascia and infiltrating into both proximal trapezius muscles. In our department, wide excision and reconstruction with a free anterolateral thigh flap were performed. Histological examination revealed skin adnexal carcinoma, originating from the hair follicles, consistent with trichoblastic carcinoma. There was no palpable mass 5 years postoperatively, and there was no recurrence on follow-up positron emission tomography-computed tomography. Trichoblastic carcinomas are rare and difficult to diagnose, but histopathological findings include atypical basaloid keratinocytes with crowded, hyperchromatic nuclei, and increased mitotic activity. The presence of hypercellular stroma is a criterion for distinguishing trichoblastic carcinoma from basal cell carcinoma. A rare giant trichoblastic carcinoma was reported, which was the biggest one in the literature.

Intramuscular hemangioma is a rare vascular benign proliferation that can occur within any muscle, particularly in the trunk and extremities. In the head and neck region, the masseter muscle is most commonly involved, followed by the periorbital and sternocleidomastoid muscles. Diagnosing intramuscular hemangioma is challenging because there are no characteristic symptoms; instead, magnetic resonance imaging is the best imaging modality to diagnose these lesions. Complete surgical resection is the treatment of choice, although the local recurrence rate is high. Herein, we report a rare case of intramuscular hemangioma located in the zygomaticus minor muscle, which is related to smiling and usually runs along the orbicularis oculi muscle. Distinguishing or separating these two muscles is challenging. However, based on the muscle vector of the midface and radiological findings, the two muscles were successfully separated. The zygomaticus minor was cut very slightly to approach to the lesion and the muscle fibers were split to excise it. A follow-up examination revealed no nerve damage or muscle dysfunction at 4 weeks postoperatively. This rare case may serve as a reference for managing intramuscular hemangioma in the head and neck region.

The study aims to analyze the performance-prove goal orientation and organizational culture on employee work performance of performance appraisal by placing employee work motivation as an interning variable. The study was conducted on a quota sample basis with 134 employees and staff in educational institutions under the auspices of Islamic educational institutions in Banyuwangi, East Java, Indonesia. Analysis through structural equation modeling (SEM) was done, and results were obtined which showed that there is an influence of institutional culture on employee motivation and that there is an effect of employee motivation on performance appraisal. However, the statistical output showed that there is no significant effect of performance-prove goal orientation on employee motivation. In testing the mediating effect, the results showed the significant influence of employee motivation in bridging the relationship between organizational culture on performance appraisal, and performance-proven goals and performance appraisal. The theoretical contributions of the findings were in its examination of performance-prove goal orientation with motivational encouragement in educational institutions to analyze the extent to which an individual's self-confidence was able to integrate patterns in distinguishing the approach used, how to use, and the response to a specific situation of directing toward organizational achievement.
