Ultrafine cadmium ferrite particles have been investigated by X-ray diffractometry, transmission electron microscopy and SQUID magnetometry. All peaks of X-ray diffraction patterns are broad, but correspond to a cubic spinel structure with the lattice constant of 8.65 $\AA$. The average particle size determined by TEM is 9.7 nm and the size distribution of particles is not normal, but lognormal. The maximal magnetization measured at 5 K was 17.7 emu/g. The experimental data show a transi-tion from a disorder ferrimagnetic phase to a spin-glass phase (i.e. reentrant behavior) with a freezing temperature (T$\_$f/) of 30 K. Superparamagnetic behavior of the particles is confirmed by the coincidence of the plots of M vs. H/T for 100 and 300 K.

The purpose of this study is to investigate the differences in irrational faith and the school adaptation of elementary school students by experimental group and control group. To achieve these goals, the followings are setting the programs. The subjects are selected from grade 4, 5, 6 students from the elementary schools. The tools used for this study were Irrational faith Test and School adaptation Test. The followings are the results of the analysis of the collected data. First, in the analysis of irrational faith, there is no significant difference between experimental group and control group. Second, in the analysis of school adaptation, there is significant difference between experimental group and control group(t=.05, p<.05).

Tic disorders, including Tourette syndrome, are known as neurobiologic disorders and as such, much emphasis has been placed on isolating genetic determinants. Although previous reports involving studies of discordance among monozygotic twins have shown the importance of genetic predisposition, they have also supported a role for environmental factors in the development of tic disorders. Therefore, it is important to consider that both genetic and environmental factors contribute to their clinical expression. The goal of this article was to review recent reports regarding the role of environmental factors in development and progression of tics. Specific environmental factors associated either with a more severe course of illness or improved outcomes were discussed. Given that accumulating evidence had suggested the usefulness of behavior therapies in the suppression of tic disorders, particular emphasis was placed on the impact of several contextual factors.

We have studied the effect of sintering temperature and time on the cation ordering and second phase formation in Ba(Mg/sub 1/3/Nb/sub 2/3/)O₃(BMN) microwave ceramics by using transmission electron microscopy. The relationship between the structural-chemical behavior arid microwave dielectric properties has also been investigated. It is revealed that according to the sintering conditions the BMN ceramics show very diverse local ordering behavior, such as the development of domain twinning and "core-shell"-structured grains and the formation of local disordered domains, though having 1 : 2 cation ordering structure basically. The disordered structure is found in Mg-excess region. Such local chemical variation seems to be caused by the formation of BaNb₂O/sub 6/-like second phase in its neigh-boring grain boundary. The microwave dielectric quality factor of the ceramics decreases greatly with the increase of the structural-chemical inhomogeneity and diversity.

To ensure the autonomy of nursing care aetivies is one of the major and most interesting issues in the field of nursing. The pertaining autonomy demands the nurse to make decisions of her or his own with out interference and free of help from other sides of health care agency. The whole process of autonomous nursing behavior should be judged and conveyed by the nurse only on the basis of the internal factors of her care to solve the problems of the client's disorder in health. Truth of nursing science and relevence of nursing conduct depend on our construction of internal basis and establishment of self-sufficient reference system. The information for efficient decision-making at the scene of nursing can only be supplied by a systematic body of nursing science consisting of true or properly corroborated propositions. The science of nursing can be autonomous when we have framework of explanation, independently of other sciences and the behavior of nursing care can factually be independent of and peculiar to that of other but similar fields only when the science of nursing is correspondently autonomous.

The purpose of this study was to examine emotional and behavioral problems of children from broken families. The subjects of the study were 200(100girls, 100boys) 5th and 6th grade children from P city in Kyuug-gi area. The main results were as follows; First, children from broken families showed some behavior problems such as aggressiveness, anxiety, developmental disorder, absences from school, bad-habits and attention-seeking behaviors. The parenting behaviors of broken families were characterized as negative, rejective, and inconsistent behaviors. Second, emotional and behavioral problems of children from broken families varied as a function of child sex, care giver, reason of loss and parenting.

An 11-year-old, toy poodle dog was presented with dermatologic lesions and mammary gland tumor (MGT) evaluation. A solitary, lobulated MGT (size $2.5{\times}3.5$ cm) was affecting the 5th left mammary gland. Firm, oval plaque skin lesions were present on the left dorsal carpal area. The skin lesions were alopecic and salivary staining. The dog had historical separation anxiety and excessive licking of skin lesions were observed. Based on the clinical and histopathologic examinations, MGT was diagnosed with mammary complex adenoma and the skin lesions were diagnosed with acral lick dermatitis. Behavior modification treatment using oral clomipramine was effective.

Hepatic encephalophthy was diagnosed with serum chemistry, abdominal radiography and ultrasonography in a 2.6kg, 4 year-old maltese dog showing signs of hypersalivation, involutary spasm of facial muscles, ataxia, behavior abnormalities like dullness, sleep disorder, restlessness. In serum chemistry, the level of alanine transferase and aspartate trasferase was mildly elevated, ammonia was severely increased. On abdominal radio-graphs, the size of liver was mildly decreased. In ultrasonographic examination, diffuse lesion with hyperechoic change and decreased vasculature were seen in the hepatic region. But vascular abnormalities of liver were not observed. Drug and dietary therapy were undertaken and severities of clinical sign were alleviated.

The purpose of this study was to detect early children with hyperactivity which is one of the symptoms of Attention Deficit-Hyperactivity Disorder (ADHD). This study used two methods: K-CBCL and observation of children's behavior. K-CBCL was done online by parents at home. For observation of children's behavior, the school asked children to wear a 3-axis accelerometer on their wrists. The data from K-CBCL and 3-axis accelerometer were analyzed and clustered to separate hypersensitive children from ordinary children. This experiment confirmed that 3-axis accelerometer which is one of Ubiquitous techniques and the K-CBCL questionnaire were helpful for detection of hypersensitive children.

Behavioral problems could be easily observed in patients with various mental disorders, and may be inevitable. Self-injurious behavior(SIB) can be defined as a deliberate or subconscious alteration or destruction of one's body without conscious suicidal intent. SIB frequently involves oral tissues and could vary from a trifling injury to damages that could lead to further disabilities. The cases presented in this report discuss oral SIB due to Tic disorder and ADHD and their treatments. Clinicians should be well aware of the possibility of oral SIB in various mental disorders as well as the diverse depths of such behaviors accordingly. Moreover, different treatment modalities should be prioritized according to the causative mental disorders.
