Objective : This study aimed to investigate the effect of community-based Goal-Achieving program in geriatric depressive symptoms preliminarily. Methods : We obtained data from elderly Korean subjects with major depressive disorder (n=51) aged 60 years or older at baseline, taking case management from community mental health center. Subjects were randomly assigned to intervention group (n=24) and control group (n=27). We investigated depressive symptoms through Short Form Geriatric Depression Scale-Korean version (SGDS-K) at baseline and every month for 3 months to all subjects. We tested interaction between group and time in SGDS-K score to evaluate the effect of program. And post hoc test examined between group differences of SGDS-K at each time points. Results : In quadratic linear mixed effects model analysis, interaction between group and time was statistically significant (Total SGDS-K score : coefficient=0.29, p<0.001 ; SGDS-K dysphoria subscale : 0.18, p<0.001 ; SGDS-K hopelessness subscale : 0.05, p=0.089 ; SGDS-K cognitive impairment subscale : 0.06, p=0.003). And significant between group difference was shown in post hoc test at time points of third month (SGDS-K score of control group : SGDS-K score of intervention group=$10.74{\pm}3.482$ : $7.25{\pm}4.475$, p=0.0184). Conclusion : These results may suggest that 'Community-based the Goal-Achieving program' has efficacy in reducing geriatric depressive symptoms.

Purpose: This study was aimed to analyze the contents and trend of published research in oncology nursing during the past five years in Korea and to suggest the direction for future research. Methods: Using the key words "cancer", "cancer patients", and "tumor", 391 nursing research published from 2003 to 2008 were selected for the analysis. Results: 1) Three hundred fifty-five (90.8%) of the studies used quantitative research approach, whereas most studies were descriptive in nature. 2) The main subjects of the study were cancer patients with mixed diagnosis (36.4%) and breast cancer patients (20.0%). 3) Complementary alternative therapy (28.9%), educational program (25.6%), and psycho-social and spiritual program (16.7%) were the most frequently used nursing interventions. Most frequently measured outcome variables were psycho, socio, and spiritual factors (38.8%), symptoms (28.2%) and physiological factors (14.6%). 4) Most frequently used key words were identified as quality of life, fatigue, coping, pain, anxiety, anorexia, and depression. Conclusion: The number of published research in oncology nursing in Korea has been increased. It is suggested to conduct international studies to develop, compare, and replicate nursing interventions for patients with cancer in future. Increasing funding, establishing research infrastructure, and removing methodological challenges are warranted for better research environment.

Ankylosis is defined as a fusion of alveolar bone with dentin and/or cementum and may occur at any time during or following active eruption. Ankylosed teeth maintain existing occlusal levels while adjacent teeth continue to erupt via deposition of alveolar bone. This may result in the clinical appearance of depression or submergence of ankylosed teeth below the occlusal plane. It is found more frequently in children of late mixed dentition and in mandibular primary molars. The problems arising from ankylosed teeth, due to their submerged positions, are elongation of the antagonist, tipping of the adjacent teeth, loss of arch length, food impaction and subsequent destruction of periodontal tissue, disturbance of succedaneous tooth eruption. The author observed several cases of ankylosed primary molars and properly managed. Following results were obtained. 1. Severe infraoccluded ankylosis results in loss of arch length and undesirable effect on eruption path of succedaneous tooth, therefore early diagnosis and management are important. 2. The teeth without problems may be examined periodically and restored in order to maintain the normal occlusal function.

Natural and expandable graphites were chemically treated in acidic aqueous solutions such as acetic acid or mixtures of acetic acid and nitric acid. Structures and thermal conductivities of the as-treated graphites were characterized in detail. Both graphites were significantly oxidized in the mixed acidic solution of $H_2SO_4$ and $HNO_3$, which condition was generally used for the oxidation of carbon nanotubes. This considerable oxidation of graphites caused a depression of their thermal conductivity. The structural characteristics, obtained by XRD and XPS, show that the graphites treated in the relatively weak acidic conditions (acetic acid or mixture of acetic acid and nitric acid) were quite similar to the untreated graphites. However, the thermal conductivities of both acidic-treated graphites were remarkably increased.

From January of 1991 to December of 1992, 42 chickens collected from 21 poultry farms and also diagnosed as necrotic enteritis(NE) was examined clinical signs, gross and histopathological findings. Main clinical signs were characterized by decreased appetite, mild to severe depression, reductance to move, ruffled feathers, greenish to yellow-browinish diarrhea sometimes including blood. As progressed, diseased chickens showed feces mixed with necrotic debris which detached from the intestinal mucosa and mostly resulted in the death. In chronic cases, there were dirty feathers around cloaca due to diarrhea and notably retarded growth. Principle gross lesions were usually confined to the jejunum and ileum, especially toward the lower part of Meckel's diverticulum. The part of small intestine was frequently distended with gas, and also showed mucosal congestion and hemorrhages with varying degrees. Sometimes, the intestinal mucosa was thickened, and also covered with fibronecrotic psuedomembrane. In addition, there were focal necrosis and severely multifocal ulcreation in the mucosa of small intestine. Major histopathological findings included villous necrosis and erosion of the small intestine covering with lots of bacterial colonies, inflammatory cell infiltration in the lamina propria, and dilatation and hyperplasia of crypts. Luminal exudate contained bacterial colonies, fibrin, erythrocytes, and desquamated epithelium. Thirteen(61.9%) out of 21 NE-occurring farms were complicated with intestinal coccidiosis.

A primary metastatic malignant plasma cell tumor was diagnosed in a 7-year-old, female mixed breed dog. The dog was admitted to Veterinary Teaching Hospital at College of Veterinary Medicine, Seoul National University after suffering from depression, anorexia, and dyspnea. In radiographic examination, a large occupying mass was found at the right cranial thorax. Due to poor prognosis, the dog was euthanized. At surgery, numerous, firm, round, nodules, 1 to 2 cm in diameter were noted in the ribs. The nodules were often confluent and had cylindrical appearance. Osteolysis was associated with the nodules. A large amount of clear fluid was present in the thoracic cavity. The spleen and liver were markedly enlarged and congested. Histologically, the mass was diagnosed as plasma cell tumor which was believed to be originate from the rib. Evidence of metastasis was observed in the spleen, liver, and kidney.

A 12-year-old, castrated male, mixed-breed dog was referred to us with a history of depression, lameness, neck and multiple joints pain. Clinical signs had been deteriorating from rear limbs lameness leading to pain on all four limbs lameness for 7 days. Mild leukocytosis and increased C-reactive protein concentration were revealed in blood work. On radiography, degenerative change of humerus and cervical intervertebral space narrowing were found. The results of synovial fluid analysis revealed severe neutrophilic pleocytosis, decreased viscosity, increased turbidity and bacterial culture was negative. The antinuclear antibody test was negative and MRI results revealed mild cervical intervertebral disk disease (IVDD). Based on all tests, we diagnosed this case as idiopathic immune-mediated polyarthritis (IMPA). Prednisolone and mycophenolate mofetil were administered and clinical signs were resolved after 7 days. This case report demonstrated that clinical, diagnostic imaging and synovial fluid analysis findings and successful treatment result with prednisolone and mycophenolate mofetil in canine idiopathic IMPA.

Nociplastic pain by the "International Association for the Study of Pain" is defined as pain that arises from altered nociception despite no clear evidence of nociceptive or neuropathic pain. Augmented central nervous system pain and sensory processing with altered pain modulation are suggested to be the mechanism of nociplastic pain. Clinical criteria for possible nociplastic pain affecting somatic structures include chronic regional pain and evoked pain hypersensitivity including allodynia with after-sensation. In addition to possible nociplastic pain, clinical criteria for probable nociplastic pain are pain hypersensitivity in the region of pain to non-noxious stimuli and presence of comorbidity such as generalized symptoms with sleep disturbance, fatigue, or cognitive problems with hypersensitivity of special senses. Criteria for definitive nociplastic pain is not determined yet. Eight specific disorders related to central sensitization are suggested to be restless leg syndrome, chronic fatigue syndrome, fibromyalgia, temporomandibular disorder, migraine or tension headache, irritable bowel syndrome, multiple chemical sensitivities, and whiplash injury; non-specific emotional disorders related to central sensitization include anxiety or panic attack and depression. These central sensitization pain syndromes are overlapped to previous functional pain syndromes which are unlike organic pain syndromes and have emotional components. Therefore, nociplastic pain can be understood as chronic altered nociception related to central sensitization including both sensory components with nociceptive and/or neuropathic pain and emotional components. Nociplastic pain may be developed to explain unexplained chronic pain beyond tissue damage or pathology regardless of its origin from nociceptive, neuropathic, emotional, or mixed pain components.

The purpose of this study was to identify the prevalence of urinary incontinence and its relating factors elderly communities. Subjects of this survey consisted of 877 elderly women and men in one Kun. Korea, who were over 60 years old. The design for this study was descriptive: the subjects were interviewed by well trained investigators from July 9. 1999 to July 20. 1999. During that survey period, the subjects were interviewed with a structured questionnaire. The data were analyzed by frequency, percentage, $X^2-test$. T-test using an SAS program. The results of the study were the following: 1. The prevalence rate of urinary incontinence was 20.1 %. of the total. The types of urinary incontinence were mixed incontinence 44.3%. stress incontinence 38.1%. and urge type incontinence 17.6%. 2. The relating factors of urinary incontinence were as follows: 1) 33.5% of UI(urinary incontinence) subjects reported urine loss once a month. twice or three times a week 23.3%. one or two times a day 17.0% 2) 38.1% of elderly reported only 1 to 2 drops. 1 t-spoon 36.9%. 1 T-spoon 15.9% 3) The volume of urine loss registered by changing underwear was 63.1 %. no necessity of changing underwear was 22.1 %. or using some type of pads was 13.1%. 4) 62.5% of UI subjects never discussed their UI problem with other people. 73.9% of the total had never experienced any treatment for their UI problem. The reasons for not receiving medical cure were their typical conception about urinary incontinence taking UI as a normal part of aging 76.2% and due to their bad financial situation 9.2%. 3. Women had more prevalence of UI than men (p=0.01), and it was found that the worse the subjective health state. the higher the prevalence of UI (p=0.001). However. there was no statistical difference in daily frequency of UI (p>0.05). The more nocturnal incontinence (p=0.001), the more intermittent stream experience (p = 0.01), the more retention experience (p = 0.01), and the more incomplete the emptying experience (p=0.001), the higher the prevalence of UI. 4. UI groups had lower ADL scores than non UI groups(p=0.01). The level of depression in the group of urinary incontinence was significantly higher than that of non incontinence group (p=0.0001). As shown above, the elderly people suffering from UI haven't been treated properly: their subjective health state and their ADL competence was lower, and their depression level was higher than non UI groups. Therefore, the development of a proper urinary incontinence management program are required so that they can lead more healthy lives. Also continual case studies for the elderly people with UI are necessary.

In recent times, the number of men with late-onset hypogonadism has increased, and interest on this topic has also increased. This study was conducted to investigate effects of the mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus on improve late-onset hypogonadism. The experimental subjects consisted of three groups: a control group consisting of 8-week-old male ICR mice that had undergone no treatment, an aging-elicited group (AE group) consisting of 50-week-old ICR male mice that had undergone no treatment, and a Mixed herbal extract treatment group (MT group) consisting of 50-week-old ICR male mice that had undergone the mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus treatment (0.1 g/kg/day) for 6 months. After the experiment, the mice from all the experimental groups were dissected, and they were analyzed through histochemical and immunohistochemical methods. The mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus reduces aging-induced cell damage and oxidative stress and increases the secretion of serotonin and B-endorphin in aged mice, and promotes spermatogenesis in seminiferous tubules and reduces apoptosis and oxidative stress, and increases androgen receptor, $17{\beta}-HSD$ and GnRH, increases the ratio of smooth muscle to collagen fibers in the corpus cavernosum, increases eNOS, decreases PDE-5 and oxidative stress in aged mice, so it improves depression, reproductive, sexual problems caused by Late-onset hypogonadism. the mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus inhibits the induction of osteoporosis by increasing decreased bone matrix distribution due to aging, increasing the activities of OPC and OPN, which are produced in osteoblasts, and decreasing RANKL, MMP-3 activity, increasing OPG activity. It also reduces muscle damage, oxidative stress, inflammation and apoptosis of muscle tissue, and increases Myo-D in the sartorius muscle of aged mice for improving muscle atrophy caused by by Late-onset hypogonadism.
