Isolated stress fracture of the first rib is rare, and repeated muscular pulling and fatigue of bone is thought to be responsible for this fracture. The diagnosis can be made by taking a thorough history and performing chest roentgenography, computed tomography or magnetic resonance imaging. Conservative treatment generally cures this condition. We report here on a case of exercise-induced isolated stress fracture of the first rib in a non-athlete college student and we review the related articles.

Childhood narcolepsy is one of the underdiagnosed diseases even the first symptoms often appear in childhood. Making diagnosis through history taking is not always easy because the symptoms of childhood narcolepsy are different from those of adulthood. Diagnostic laboratory tests such as sleep studies, tests for human leukocyte antigens, cerebrospinal fluid hypocretin measurement should be considered when the child has excessive daytime sleepiness without cataplexy. Treatment approach should be start as early as possible to avoid secondary academic, emotional difficulties. Both pharmacological and non-pharmacological management, and close cooperation between parents and school teachers should be maintained. In the near future, childhood narcolepsy can be a key to understand the pathogenesis of narcolepsy.

Organisms living in the Arctic and Antarctic regions are exposed to strong constraints, of which temperature is a driving factor. Evolution has led to special adaptations, some with important implications at the biochemical, physiological, and molecular levels. The northern and southern polar oceans have very different characteristics. Tectonic and oceanographic events have played a key role in delimiting the two polar ecosystems and influencing evolution. Antarctica has been isolated and cold longer than the Arctic; its ice sheet developed at least 10 million years earlier. As an intermediate system, the Arctic is a connection between the more extreme, simpler Antarctic system and the very complex temperate and tropical systems. By studying the molecular bases of cold adaptation in polar fish, and taking advantage of the information available on hemoglobin structure and function, we analysed the evolutionary history of the ${\alpha}\;and\;{\beta}globins$ of Antarctic and Arctic hemoglobin using the molecular clock hypothesis as a basis for reconstructing the phylogenetic relationships among species.

Objective : The authors investigate appropriate evaluation and surgical methods in treatment of the cerebral paragonimiasis accompanying epilepsy. Methods : Thirteen patients with the cerebral paragonimiasis accompanying epilepsy were included for this study. Preoperative evaluation methods included history taking, skin and serologic tests for Paragonimus westermani, neurologic examinations, computerized tomography, magnetic resonance imaging, amytal test, PET or SPECT, and video-EEG monitoring with depth and subdural grid electrodes. Seizure outcome was evaluated according to Engel's classification. Results : Surgical methods were temporal lobectomy including lesions in six, lesionectomy in five, and temporal lobectomy plus lesionectomy in two. Postoperative neurological complications were not noticed, and seizure outcomes were class I in 12 patients [92%], class II in one [8%]. Conclusion : In patients with a cerebral paragonimiasis accompanying epilepsy, further evaluation methods must be done to define the epileptogenic zone, and complete resection of the epileptogenic zone with different surgical methods should be performed for seizure control.

Purpose - This study sought to discuss definitions of organizational culture taking into consideration different views, and the historical and philosophical elements of organizational culture. Research Design, Data, and Methodology - This paper is a relatively conceptual study that has attempted to define organizational culture, a topic that has been debated among scholars and practitioners. Various studies in the literature related to organizational culture have been reviewed in an effort to reduce the complexities and ambiguities in definitions of organizational culture. Results -This study summarized and synthesized different studies related to organizational culture, and identified the main streams for defining organizational culture as being from the historical and philosophical elements of organizational culture. Conclusions -The concept of organizational culture continues to be an important factor affecting organizational effectiveness and initiating organizational development. However, the definition of organizational culture has not been well-established. In this sense, this paper seems to be significant and meaningful as it attempts to define organizational culture from different perspectives.

The travellers using social media leave their location history in the form of trajectories. These trajectories can be bridged for acquiring information, required for future recommendation for the future travelers, who are new to that location, providing all sort of information. In this paper, we propose a personalized travel path recommendation scheme based on social life log. By taking advantage of two kinds of social media such as travelogue and community contributed photos, the proposed scheme can not only be personalized to user's travel interest but also be able to recommend a travel path rather than individual Points of Interest (POIs). It also maps both user's and routes' textual descriptions to the topical package space to get user topical package model and route topical package model (i.e., topical interest, cost, time and season).

This study explores the building process of innovative capability through overseas direct investment (ODI) by taking the camera business of Samsung Aerospace Industry (SAI) as a case. SAI with less than 20 years history has pursued an aggressive ODI and developed its own camera models. It acquired Rollei in Germany and Union in Japan in 1995, for acquiring advanced technology. Several factors leading to the success of SAI's innovative capability building were taken into consideration. Fists, SAI effectively absorbed technological knowledge by exchanging technical personnel with foreign partners. Second, it chose right partners with the complementary knowledge required for advancing its technological capability. Third, it strengthened its competence to satisfy the technical standards of the partner companies in OEM trade relations. Fourth, ti successfully formed a global marketing network in which subsidiary companies plays a central role in each region. Finally, SAI successfully addressed the factors of mutual respect between partners in order to let its partners to be confident in their ventures.

A four-year-old female Pekingese dog was presented with intermittent ambulatory hindlimb lameness and severe back pain. The course of the disease was acute and static and 5 days passed by until presentation. In neurological examination, severe back pain and slightly decreased proprioception in right hindlimb were shown. In radiographic examination, radiopacity was increased at T10-11 intervertebral disc space. According to the history taking, neurological examination and radiographic examination, it was tentatively diagnosed as intervertebral disc disease (IVDD). Conservative treatment was performed including cage rest, medication with prednisolone and traditional acupuncture. Acupoints were GV-6, GV-7, BL-18, BL-19. BL-40 and GB-34. Dry needlings rested for 20 minutes. Just after the first acupuncture treatment back pain was significantly decreased. With additional acupuncture treatment, all the clinical signs were not observed. It is considered that conservative therapy including traditional acupuncture, medication and cage rest might be the first choice of therapeutic method for Grade I or II IVDD in dogs.

A 4 months old Golden retriever male dog was referred. By the history taking, it was kwon that the mass has been formed at the parietal region of the patient after fourth prevention inoculation. The appetite, urination and excretion were normal. The mass confirmation which was limited in the parietal region, did not seem to be enlargement of lymph node from physical examination palpation. Complete blood count and serum biochemical profiles were consistent with mild lymphocytosis, mild monocytosis, anisocytosis, regenerative anemia and elevated ALP, CPK. Survey radiographs indicated a mixed density in parietal region. We performed surgical resection and chemotherapy for cure and biopsy. Histological finding was periosteal fibrosarcoma. The application of cisplatin was topically used in operation site. Up to now the indication of recurrence is not visible.

A 4-week-old infant presented with a coagulation disorder resulting from a vitamin K deficiency. The vitamin K deficiency was caused by neonatal cholestasis due to biliary atresia. Jaundice, hepatomegaly and pale stools are the predominant presenting symptoms of biliary atresia, none of which were recognized in our patient before admission. However, the patient presented with bleeding caused by vitamin K deficiency. She was fully breastfed and had received adequate doses of vitamin K at birth and from the age of 1 week. In case of a hemorrhagic diathesis due to neonatal cholestasis, timely identification of treatable underlying disorders, in particular biliary atresia, is important because an early surgical intervention results in a better prognosis. Meticulous history taking and a thorough physical exam can be decisive for an early diagnosis and subsequent intervention.
